The Abnormally High Non-Cosmic Radioactivity in Neanderthals and the Underestimated Effect of Atomic Tests on Human Populations in Central Africa

Authors: Alexis Zaganidis
Comments: 17 Pages.

1) The "great" statistical anomaly of "natural" radioactive radiation. The "natural" radioactive radiation can be separated into two "independent" sources : cosmic one and terrestrial one or non-cosmic one. In order to have an over-optimized human intelligence, the sum of these two "independent" sources has been greatly minimized thanks to the fine tuning of physical constants, thanks to a very particular cosmic formation called the KBC Void and thanks to a very particular planetary formation in the case of the Earth itself. 2) The atomic tests on tropical islands between 1946-1967 (previously evacuated of all human life) have heavily irradiated these tropical islands and have therefore boosted the fungal diseases of tropical living organisms. The mosquito is one of the most mobile & dynamic tropical living organisms and therefore the most sensitive & susceptible to fungal diseases which greatly reinforce the supremacy of static life. Therefore, the atomic tests on tropical islands have had a very positive effect against malaria and all tropical diseases transmitted by mosquitoes.

Authors: Hyunho Shin
Comments: 8 Pages. (Note by viXra Admin: Further speculative work will not be accepted!)

This study describes the development of an expression system for an oral Zika virus vaccine. The vaccine is based on a fusion protein of the cholera toxin B subunit (CTB) and the Zika virus envelope protein (E protein), connected via a GGSG linker and expressed in Saccharomyces cerevisiae. The ADH1 promoter was incorporated into the yeast expression vector to drive transcription of the fusion protein. Yeast transformants were confirmed through colony PCR, and initial protein expression was validated using SDS-PAGE.

A Physics Perspective on Trial and Error Evolution and Intelligence

Authors: Eran Magshim Lavi
Comments: 10 Pages. Distributed under CC BY-NC 4.0

This article investigates the pivotal role of Energy in trial-and-error evolution (TAEE). I commence by discussing the Uncertainty principle, which introduces fundamental randomness to physical phenomena and imparts random variability to the TAEE (trial and error evolution). As Energy is the sole component of our Cosmos, the TAEE reflects in Energy and its changes: its exertion capabilities, storage, and ad hoc planning (of Energy exertion.) I then investigated TAEE as reflected in the emergence of intelligence. The Least action principle controls Energy movement in space-time; thus, intelligence emergence directly connects to structures' ability to use the Least action principle. For example, first-level nonintelligent structures (e.g., elementary particles, simple replicating molecules) cannot plan a path, and the Least action principle completely predetermines their infinitesimal movements. They cannot control their Energy exertion, store Energy, or plan ad hoc. After a long process of TAEE, intelligent structures emerged with advanced Energy control, robust Energy storage, and ad hoc planning, allowing complete ad hoc path planning and the ability to make unrestricted mid-course path adjustments. This progression underscores the intricate relationship between Energy dynamics, trial and error evolution, and intelligence evolution.

Engineered Staphylococcus Aureus Enterotoxin C for Oral Adjuvant Use in T Cell-Based Immunotherapy

Authors: Hyunho Shin
Comments: 6 Pages. (Note by viXra Admin: Further speculation will not be accepted!)

Staphylococcus aureus enterotoxins are potent superantigens known for inducing strong T cell activation, which can lead to cytokine storms and significant immune responses. Recent advancements in T cell-based cancer immunotherapies, including CAR-T cell therapy and immune checkpoint inhibitors, highlight the potential role of modified superantigens as adjuvants to boost immune activation. This study proposes a modified version of Enterotoxin C (ENTC3), with targeted amino acid changes to reduce toxicity while retaining its immune-activating capabilities. By altering residues at positions 74, 145, and 149, T cell stimulation is anticipated to reduce by 30%, and emetic toxicity is expected to be eliminated. Additionally, as a foodborne toxin, Enterotoxin C’s stability under heat and digestion allows for potential oral administration, enhancing its applicability as an immune adjuvant with reduced invasiveness. Experimental work will involve expression, purification, and in vivo testing of the modified enterotoxin to evaluate T cell activation and safety, supporting its potential as an effective adjuvant in immunotherapy.

Modification of Campylobacter Cytolethal Distending Toxin for Selective Targeting of PD-L1 Expressing Cancer Cells

Authors: Hyunho Shin
Comments: 8 Pages.

Cytolethal Distending Toxin (CDT), a tripartite exotoxin from Campylobacter jejuni, is known for inducing DNA damage and apoptosis. In this study, we engineered the A subunit (CDTA) to selectively target cancer cells by replacing its native binding region with anti-PD-L1 antibody sequences. Using sequence data from UniProt (CDTA: A1VXG4, PD-L1: Q9NZQ7), we identified and modified CDTA’s residues 129-140. Structural validation using AlphaFold 2 confirmed that these modifications retained CDTA’s structural stability and affinity for PD-L1, supporting its potential as a targeted cancer therapeutic. Future experimental steps include protein expression, purification, and cytotoxicity testing to confirm the toxin’s selective binding and apoptotic effects on PD-L1 positive cancer cells.

Development of a Silk Fibroin Scaffold for Gingival Regeneration: Formulation, Efficacy Testing, and Expected Clinical Application

Authors: Hyunho Shin
Comments: 7 Pages.

Gingival recession, characterized by the apical migration of gingival tissue, leads to root exposure and subsequent complications such as sensitivity, root caries, and periodontal disease. Current treatment options, including tissue grafts and regenerative therapies, are limited by their invasiveness and inconsistent outcomes. This study proposes a silk fibroin scaffold infused with three growth factors (EGF, FGF, VEGF) and three adhesive proteins (laminin, fibronectin, osteonectin) to enhance gingival cell proliferation, attachment, and integration with the alveolar bone. The scaffold aims to promote natural gingival regeneration while providing structural support. The development process, efficacy testing, and expected clinical application of this novel gingival regeneration scaffold are outlined. This approach, if successful, could offer a safer, non-invasive, and cost-effective solution for treating gingival recession.

[Speculation on a] Novel Approach for Alzheimer’s Disease Treatment: Inhibition and Degradation of Beta-Amyloid 42 Aggregates Using a Nasal Ultrasonic Nebulizer for Peptide Delivery

Authors: Hyunho Shin
Comments: 10 Pages.

This study proposes an innovative therapeutic approach for Alzheimer’s disease (AD) targeting the aggregation and clearance of the neurotoxic amyloid-beta 42 (Aβ42) peptide. Utilizing computational design tools such as AlphaFold 2, we identified and optimized functional peptides capable of binding the hydrophobic C-terminal region of Aβ42 to prevent aggregation and promote degradation via the ubiquitin-proteasome system (UPS). This non-invasive strategy envisions peptide administration through a nasal ultrasonic nebulizer, which could bypass the blood-brain barrier (BBB) and deliver peptides directly to the brain. The concept focuses on the potential of combining targeted peptide design with a delivery system that enables rapid, brain-specific absorption, presenting a novel direction for AD therapy.

A Bio-Technical Trick for the Ultra-Precise Detection of Infectious Airborne Viruses.

Authors: Alexis Zaganidis
Comments: 11 Pages.

Virology is at the crossroads of five frontiers : medicine, molecular biology, biochemistry, physics and human rights. In Western countries, the role of physics in virology is completely minimized while it plays the absolute greatest role. Interdisciplinarity is also of paramount importance in theoretical physics because of the quest for a unified theory between quantum fields and general relativity. Einstein’s theory is so powerful because it can very well formulate its own limits (one cannot go faster than the speed of light in all inertial frames). This incredible theoretical paradigm can also be developed in Virology. The first part and most important part of the present article is about a bio-technical trick for the ultra-precise detection of infectious airborne viruses. The second part of the present article is about the Theoretical Characteristics of the Omicron variant. The third part of the present article is about the Duality of the Omicron variant. And the fourth and least important part of the present article is about the Origin of the SARS-Cov-2 virus.

A Model and Genomic Evidence of Imprinting DNA Sequence on Water Structure

Authors: Ivan V. Savelev, Michael M. Rempel, Alexandr V. Vikhorev, Oksana O. Polesskaya, Alexandr V. Vetcher, Richard Alan Miller, Max V. Myakishev-Rempel
Comments: 36 Pages.

A novel model is presented of DNA-water interactions within the cell nucleus, proposing a mechanism for continuous self-reorganization of water structures around DNA. The model suggests that DNA sequences may imprint information onto water through shifting layered structures, facilitating sequence-specific chromatin folding. A key feature of this model is the homologous sequence-specific adhesion of repetitive DNA elements, particularly transposons. In this process, two identical double-helical DNA sequences stick to each other in head to head orientation via transverse water layers, without unwinding or separating their strands. This adhesion is proposed to drive perpetual, dynamic chromatin refolding by pairing identical transposons to form large DNA loops and helices to form 30nm fibers and higher-order chromatin structures. The model postulates the existence of a chromatin code based on the positions of transposons in introns and intergenic sequences, offering a new perspective on the functional significance of these often overlooked genomic regions. Predictions based on this structural model were tested using genome sequence data, revealing specific patterns in purine sequence distribution and nucleotide homology that provide preliminary support for the model. This framework suggests novel functions for repetitive DNA sequences and proposes that sequence-specific chromatin refolding may serve as a mechanism for cellular sequence-guided information processing and self-regulation. While largely theoretical, the model generates testable predictions and suggests new directions for research. Several experimental approaches to validate the model are proposed, emphasizing the importance of in vivo studies or experiments closely mimicking nucleoplasm conditions. This work may have significant implications for understanding gene regulation, developmental biology and physiology, with potential applications in fields such as regenerative medicine and cancer research.

Questioning Darwin-Malthusian Hypothesis: Remark on Critics to Darwin’s Evolutionary Process of History, from Ernst Cassirer to Jaroslav Flegr

Authors: Victor Christianto, Florentin Smarandache
Comments: 14 Pages. published in Octogon Mathematical Magazine, vol. 32, no. 1, 2024

As Rev. John Polkinghorne, the late professor of mathematical physics and priest, wrote:"The idea of a ready-made world was replaced by that of a creation so endowed by its Creatorwith potentiality that creatures could be allowed ‘to make themselves’ (Charles Kingsley)through the explorations of evolutionary process. The history of the world is to be understood as an unfolding act of continuous creation. Such a creation is a great good, but it has an inescapable shadow side for evolution results not only in great fertility but also in blind alleys and extinctions. Genetic mutation produces both new life forms and also malignancy, and one cannot have the one without the other. Theology can find here some help from science as it wrestles with the perplexities of natural evil and suffering." (cf. Polkinghorne, The University of Edinburgh, 2009). Notably several scholars have come up with differentarguments to criticize Darwin’s evolution theory, for instance Ernst Cassirer Vern Poythress with Interpreting Eden, and Jaroslav Flegr, with his book Frozen evolution, that is not the way it is, mr Darwin. The present review is intended to bring more arguments in particular from recent development of low-temperature physics and its connection to cosmology.

The Origin of Life as Life Being the Most Involved with Fundamental Physics

Authors: Alexis Zaganidis
Comments: 5 Pages.

The origin of life can been seen as the first original anti-entropic engine with respect to a pressure-temperature reference. Therefore, under that theoretical paradigm, the chemolithoautotrophic bacteria are the best candidates by far for the origin of life. To have a more detailed description of the the origin of life, we consider the concept of "fungal catastrophe" from nuclear-biology and we also consider the many-worlds interpretation (MWI) with an almost infinitely large number of quantum parallel universes. In the present article, we will use many times the shorter designation "anti-entropic engine" instead of the longer designation "anti-entropic engine with respect to a pressure-temperature reference".

What is Cancer?

Authors: Junichi Hashimoto
Comments: 9 Pages.

Relational physics, which I founded, is essentially a theoretical system in physics, but it is a theory of everything that can be applied to all other disciplines. In this paper, I attempted to apply the ideas about energy to medicine (cancer mechanisms) in order to establish new methods of treatment and prevention. Based on the numerical values of nerve pulses (electrical energy) generated in the human body, the various other factors that make up these pulses were also quantified, contributing to the derivation of the most rational model for protecting somatic cells from excessive pulse energy. It came to fruition as synaptic therapy. This study is unique in that it identified the root cause of cancer not in somatic cells but in cranial nerve cells, and elucidated its meaning in a holistic and comprehensive manner, intertwining it with cosmic and global organismic theory.

Physics Source for Intelligence

Authors: Eran Magshim Lavi
Comments: 9 Pages. Distributed under CC BY-NC 4.0

In physics, Energy is the fundamental component of the Cosmos, integral to all processes and changes. Evolution, through trial and error, must adhere to the restrictions of the "Energy Conservation Principle," just like all other processes in space-time. The development of both nonintelligent and intelligent structures is driven by Energy changes, and the "Uncertainty Principle." Nonintelligent structures lack ad hoc planning. Through an extensive evolutionary process of trial and error, intelligent structures emerged from nonintelligent ones, gaining capabilities for advanced Energy exertion control, increasing Energy storage capabilities, ad hoc planning, and bypassing the "Least Action Principle."

Novel Physical, Chemical and Nuclear Phenomena Driving and Driven by Neutrino Oscillations

Authors: Reginald B. Little
Comments: 23 Pages.

A new theory is further developed for internal nucleon, quark and gluon structures for understanding new solar neutrino interactions changing macroscopic matter, nanoparticles, molecules, atoms, nuclei, and nucleons. The theory determines that dynamical phenomena involving quantum fluctuations down to nuclei, nucleons, quarks, and gluons induce fractional reversible (FR) fissing and fusing of quarks and gluons nuclei and into surrounding electronic shells for activating stronger neutrino interactions for larger neutrino cross-sections. Also, such theory is described for understanding dimensionality and effects of dimensions of gluons-quark interactions. Proof of such solar neutrino driven phenomena occurring is given in earth’s atmosphere, earth’s core, earth’s lithosphere, earth’s biosphere and earth’s hydrosphere. The gallium induced graphene and diamond formations are catalytically explained by such neutrino interactions. Proton induced diamond is explained by such solar neutrino interactions. Proteins and ATP activations are explained by solar neutrino interactions for driving biomolecules for life on Earth. Life in Venusian clouds is rationalized by this theory of the author of solar neutrinos driving molecules in the clouds of Venus. The recently observed accelerations of cancer and bacterial cell growths on the International Space are explained by the solar neutrino interactions given by this theory. On the other hand, the recent observation of reversal of aging by submersion in ocean water is explained by the author’s dynamical neutrino interactions for driving biomolecules. Effects on life of elevating terrestrial life into orbit like International Space Station (ISS) are explainable by this introduced solar neutrino interactions with nuclei in the living organisms.

Algebraic Model of Genetic Code and Biospin (In English)

Authors: Sergey Y. Kotkovsky
Comments: 32 Pages. English version of Russian paper viXra:2406.0163

Based on the algebra of biquaternions in isotropic basis, we have built a model of the DNA genetic code that describes nucleotides, doublets and triplets. Each nucleotide in this model is represented by its own biquaternion. Together, these four nucleotide biquaternions form the basis of the entire biquaternion space. The model justifies the grouping of triplets which are encoding the same amino acids. It is possible to trace direct correspondences between the algebraic structures of our model and the spin wave functions studied in quantum relativistic field theory. This suggests a special quantum-like nature of the structures of the genetic code. A new biquaternion representation of the Dirac equation is obtained, the establishment of connections with which allows one to see the chiral states in the DNA structure. The mathematical nature that characterizes the genetic code specifies a particular skew-symmetric type of noise immunity, which is based on the operation of parallel complementary channels of code implementation.

На основе алгебры бикватернионов в изотропном базисе нами построена модель генетического кода ДНК, описывающая нуклеотиды, дуплеты и триплеты. Каждый нуклеотид в этой модели представлен своим бикватернионом. Вместе эта четвёрка бикватернионов нуклеотидов образует базис всего бикватернионного пространства. В рамках модели обосновывается группирование триплетов, кодирующих одни и те же аминокислоты. Можно проследить прямые соответствия между алгебраическими структурами нашей модели и спиновыми волновыми функциями, изучаемыми в квантовой релятивистской теории поля. Это даёт основание предположить особую квантово-подобную природу структур генетического кода. Приводится новое бикватернионное представление уравнения Дирака, установление связей с которым позволяет увидеть киральные состояния в структуре ДНК. Математическая природа, характеризующая генетический код, задаёт особый кососимметрический тип помехоустойчивости, в основе которой лежит работа параллельных взаимодополнительных каналов реализации кода.

Plausible Photomolecular Effect and Microwave in Phase Transition of Water as a Newdawn for Renewable Energy and Ensemble-Holistic Approach to Health Management

Authors: Victor Christianto, Florentin Smarandache
Comments: 8 Pages.

Interaction among light and water molecules have baffled scientists for many decades, and even centuries. In this regards, photons in the visible spectrum, where bulk water normally doesn't absorb light, can surprisingly cleave off large water clusters from the water-vapor interface, according to a recent study by Tu and Chen (2023). This discovery, termed the "photomolecular effect," opens exciting possibilities for not only revolutionizing renewable energy but also paving the way for a more integrated-ensemble approach to health management (cf. Smarandache & Christianto, 2010; Tu &Chen, 2023; Tu et al., 2024). In a sense, other than with green or red LED, we can also introduce low intensity laser to alter water molecule, as we discussed earlier in this journal (cf. Christianto, Chandra,Smarandache, 2023a; 2023b).

Theory of Solar Anti-Neutrinos Stimulating Clumped 13C in Biomolecules for Causing Cancer

Authors: Reginald B. Little
Comments: 3 Pages.

A mechanism for 13C causing cancer is further evidenced on basis of solar antineutrinos selectively stimulating 13C relative to 12C due to years of eating foods enriched in 13C like from C4 plants and years of exposure to solar antineutrinos with 5 MeV anti neutrinos selectively stimulating 13C for gamma emission and damage to surrounding DNA and proteins for cancer genesis. The cumulative effects of the enrichment of 13C in tissue from diet of the host and the years of bombardment with solar anti-neutrinos and low cross-sections of anti-neutrino interactions manifest logical patterns and rhythms for cancer genesis with aging in humans.

Rotations of Electromagnetic Waves for Novel Chemical Dynamics: Decomposition of PAFS and Synthesis of BC8 Super-Diamond

Authors: Reginald B. Little
Comments: 5 Pages.

A new theory is given for the decomposition of PFAS and the formation of BC8 Super-diamond by application of RBL’s rotating magnetic field and static magnetic field for stimulating nuclei having nonzero nuclear magnetic moments (NMMs). The induced NMMs are proposed more readily in the 19F of PFAS due to large mass defect of 19F and the many C-F bonds per molecule. The superdiamond is reasoned to form with its body center cubic lattice with central carbon atom per cube due to the rotating magnetic field and resulting internal induced sp3 hybridization with more efficiency for the applied external pressure to be better used to compress the resulting sp3 carbon atoms to BC8 super-diamond.

A Preliminary Investigation of Open-Ended Evolution in Two-Dimensional Discrete Dynamical Systems

Authors: Perry W. Swanborough
Comments: 15 Pages.

Open-ended evolution (OEE) of interacting elementary cellular automata (ECA) was studied by Alyssa Adams et al. (2017). Some instances of composite ECA systems incorporating state-dependent dynamics were shown to satisfy definitions of unbounded evolution (UE) and innovation (INN), facilitating OEE. As an exercise in the rigorous analysis of systems not larger than sufficient to establish universal requirements for OEE, the scope of the study was restricted to small one-dimensional systems (ECAs) in which the perturbation of one subsystem by one other was one-way only (from "environment", e to "organism", o), but the authors recognized that their conclusions should also be relevant to the richer dynamics of large systems of mutually interacting subsystems. In this study, I explore the potential of three mutually interacting hodge podge machines for OEE and recognize that study of OEE in such comparatively large systems is provisionally tractable only by assessment of INN, considered as a reliable UE/OEE indicator.

"Neural Avalanches: Optimizing Neurodynamics, Network Formation, and Brain Development

Authors: Richard Murdoch Montgomery
Comments: 16 Pages.

Neural avalanches, characterized by cascading bursts of activity propagating across neural networks, are emerging as a fundamental phenomenon in brain function and development. This article explores the intricate relationship between neural avalanches and their role in optimizing neurodynamics, network formation, and information processing in the brain.Drawing from recent research findings, I delve into the criticality exhibited by neural avalanches, which put the brain at an optimal state for efficient information transmission and computational capabilities. The article examines how neural avalanches facilitate the formation of efficient neural networks through a process called "neuronal avalanche organizing" (NAO), where neurons participating in the same avalanches tend to wire together, leading to the emergence of functional neural circuits.Furthermore, I discuss the importance of moderate levels of D1 dopamine receptor activation in supporting avalanche dynamics. Appropriate D1 receptor activation helps maintain the balance between excitation and inhibition, regulating neural excitability and gain modulation, and contributing to synaptic plasticity mechanisms underlying network reorganization.Extending beyond neurodynamics and network formation, the article explores the pivotal role of neural avalanches in brain development. I try to elucidate how avalanche dynamics shape neural circuit formation, synaptic pruning, and refinement, as well as facilitate critical period plasticity and functional specialization of brain regions. Additionally, I highlight the contribution of neural avalanches to network integration and the emergence of higher cognitive functions and complex behaviors during development.By synthesizing current understanding and ongoing research, this article provides a comprehensive perspective on the intricate interplay between neural avalanches, neurodynamics, network formation, and brain development. It underscores the significance of this phenomenon in optimizing information processing, shaping neural architecture, and guiding the maturation of the brain's intricate circuitry.Word highlights: Neural avalanches, Criticality , Neurodynamics

Topology of Saliva

Authors: Arturo Tozzi, James F. Peters
Comments: 8 Pages.

Physical properties like shape, volume and size affect the dynamics of biological systems. Along these lines, we focus on the topological properties of biological fluids and their biochemical and physiological outcomes. We take as a paradigmatic example the salivary fluid and describe how its topological features may affect the physiopathology of the oral cavity. Topological approaches assess the general properties of saliva, ignoring small-scale physical details such as density, flow rate, stiffness, viscosity. Specifically, the mucin aggregates scattered in the salivary fluid can be tackled in terms of topological holes, i.e., vortical clusters that modify the direction, flow, impulse, local rate-of-change and velocity of saliva. While the current methodological approaches are inclined to remove the effects of impurities assessing systems as homogeneous structures, we argue that the occurrence of mucins breaks up the salivary fluid’s homogeneity, leading to unexpected biophysical modifications. We suggest that every collected salivary sample is not reliable for accurate clinical and experimental investigation, since it displays highly local as well as variable chemical, physical and biological features, not reflecting the current physiological state of the oral cavity. Therefore, the assessment of a single salivary sample is not fully reproducible and cannot provide information about the biophysical, enzymatic and microbiological content of the whole saliva. In sum, the very topological features of the saliva - such as volume, shape, antipodal cells, vortex area, whirling fluid mass, segmentation, discretization, triangulation, node numbering - produce unnoticed biological consequences and network connectivity features with intriguing operational implications.

By this process, a singular organization of this matrix is highlighted in both symmetrical and asymmetrical arrangements. Also, the configurations of this matrix are organized in coincidence with the alphanumeric system introduced in a recent published article by the author. This compressed version of the genetic code is called "the ultimate genetic code matrix."

Formulating a Mathematical Model for Living Systems

Authors: Nguyen Khanh Toan
Comments: 4 Pages.

Prigogine’s 1978 concept of dissipative structures, drawing parallels with living systems, forms the basis for exploring life’sunique traits. However, these identified similarities prove insufficient in capturing the entirety of life. To address this gap, ourproposed modeling approach emphasizes the distinctive ability of living organisms to observe other systems—an attributeintricately tied to quantum mechanics’ "measurement" processes, as highlighted by Howard Pattee. This article introduces acomprehensive mathematical model centered on quantum dynamical dissipative systems, portraying living systems as entitiesdefined by their observational capacities within this framework. The exploration extends to the core dynamics of these systemsand the intricacies of biological cells, including the impact of membrane potentials on protein states. Within this theoreticalstructure, the model is expanded to multicellular living systems, revealing how cells observe quantum dynamical systemsthrough protein state changes influenced by membrane potentials. The conclusion acknowledges the current theoreticalstatus of the model, underscoring the crucial need for experimental validation, particularly regarding the superposition state ofmembrane proteins under the influence of an electric field.

Comments: 9 Pages.

Almost all phenomena and structures in nature exhibit some degrees of fractionality or fractality. Fractional calculus and fractal theory are two interrelated concepts. In this article we study the memory effects in nature and particularly in biological structures. Based on this fact that natural way to incorporate memory effects in the modeling of various phenomena and dealing with complexities is using of fractional calculus, in this article we present different examples in various branch of science from cosmology to biology and we investigate this idea that are we able to describe all of such these phenomena using the well-known and powerful tool of fractional calculus. In particular we focus on fractional calculus approach as an effective tool for better understanding of physics of living systems and organism and especially physics of cancer.

In this study we present some promising models for future studies in biomedicine, including constant and variable order fractional Maxwell and Kelvin—Voigt models to study the mechanics of cancer cells. We also emphasize that fractional calculus will play a vital and central role in the understanding of the complexities that occur when we deal with the phenomena and processes in the realm of bioscience and biomedicine and particularly in physics of cancer.

Comments: 7 Pages.

Understanding biological complexity is one of the most important scientific challenges nowadays. Protein folding is a complex process involving many interactions between the molecules. Fractional calculus is an effective modeling tool for complex systems and processes. In this work we have proposed a new fractional field theoretical approach to protein folding. We have derived two coupled fractional partial differential equations that their solutions with specific boundary conditions and different values of the order of fractional derivative would describe and predict the possible contour of conformational changes for protein folding.

We conclude that the Age vs Amplitude of accommodation of eyes, can be characterised by a magnetisation curve of a Spin-Glass in the presence of an external magnetic field.

Origin of Left- or Right-Handed Byl Cellular Automata Replicators: An Analogy for the CISS Theory of Biological Homochirality Origin

Authors: Perry W. Swanborough
Comments: 6 Pages.

Homochiral biology can be recognized as the outcome of an ancestral breaking of chiral symmetry which has subsequently propagated through a broadening range of descendant dynamic networks. Recently published research provisionally accounts for the establishment of biological homochirality by demonstrating that the chiral symmetry of ribo-aminooxazoline (RAO) in racemic solution is broken by exclusive adsorption of D-RAO, a precursor of RNA, on to a naturally-magnetized mineral surface (magnetite). This proposed mechanism in the prebiotic environment would allow for subsequent unidirectional propagation of homochirality through homochiral RNA to homochiral peptides (including enzymes) to homochiral metabolism. Noting these recent chemical and physical results, I show that an origin out of broken chiral symmetry and subsequent homochiral replication of the Byl cellular automata replicator (1989) can be seen as an analogy to the origin and propagation of biological homochirality.

Gravitational and Rotational Entanglements of Nuclear Magnetic Moments for Nonlocal Biomolecular Recognition and Charging and Macro-Entanglement of Planetary Clouds

Authors: Reginald B. Little
Comments: 22 Pages. Novel Theory of entanglement of matter on subatomic and planetary sizes by Nuclear Magnetic Moments is developed further with details by Reginald B. Little.

Fermentative productions of amino acids are thought to retain homochirality. This work can propose rotational motions for accelerations by centrifugations during fermentative processes enrich heavier, stable isotopes of differing nuclear magnetic moments (NMMs) with consequent possibility of altered chirality and magnitude of rotating polarized light for altering chemical, physical and biological phenomena of such enantiomers. The author discovered gravity seeding homochirality. Thereby in this work, the author determined that altered gravity can change magnitude and direction of chirality. In this work, the changes in isotopes alter gravitational effects on metabolism of enantiomers in hosts eating fermentative produced amino acids.

The charged 1H atmosphere of Neptune is thereby the basis for charging Neptune’s atmosphere and the author thereby explains the disappearance and reappearance of Neptune’s clouds by magnetic coupling of charged atmosphere of Neptune to Sun’s magnetic field.

Consciousness and Afterlife in the Evolution of Intelligence

Authors: K. L. Senarath Dayathilake
Comments: 49 Pages.

To date, no scientific study has found reliable evidence of an afterlife; the mechanism of consciousness is two of the most challenging questions. Here, I show the hypotheses for consciousness and the probability of an afterlife through three simple thought experiments and theoretical evidence. I demonstrate the problems of consciousness, intelligence, and the brain's relationship with remaining neuroscience, physics, and psychology; and why new physics, psychology, and philosophy are needed to fulfill the gaps in research objectives. Furthermore, I discuss how and why I suggest significant probability of a continuum of consciousness - the afterlife. Findings show no alternatives other than the afterlife. In other words, I did not find different ways to discuss the results of those experiments yet. I show how and why new findings might help evolve well-being and make a better world.

Relativistic Chiral Inversion of Non-Zero Nuclear Magnetic Moments During Centrifugal Industrial Fermentative Processes

Authors: Reginald B. Little
Comments: 15 Pages. This manuscript gives powerful theory from authors prior theory of nuclear magnetic moments for explaining range of phenomena from industrial fermentative productions to lack of lightning on Venus and Neptune and Neptune's disappearing clouds!

Fermentative productions of amino acids are thought to retain homochirality. This work proposes rotational motions for accelerations by centrifugations during fermentative processes enrich heavier, stable isotopes of differing nuclear magnetic moments (NMMs) with consequent altered chirality and magnitude of rotating polarized light for altering chemical, physical and biological phenomena. The author discovered gravity seeding homochirality. Thereby in this work, the author determined that altered gravity can change magnitude and direction of chirality. In this work, the changes in isotopes alter gravitational effects on metabolism in hosts eating fermentative produced amino acids. Cancer was determined from eating heavy isotopes from fermentative processes and cancer cells were reasoned in this work to be more affected as earth’s gravitational field is reduce by travel away from earth’s surface. Similarly accelerated motional and gravitational effects on isotopes in planetary atmospheres of Earth, Saturn, Jupiter and Uranus by 14N, 15N, 1H, 3He, 13C and 17O was reasoned in this work to cause lightning. Such solvent of positive NMMs were reasoned to accumulate and exchange charges in clouds and solute negative NMMs were reasoned to alter charge for streamers to induce lightning strikes. Lack of sufficient 13C and 17O in the CO2 of Venus’ atmosphere is explained in this work to mediate lack of charge accumulation and discharge for lack of lightning on Venus. The lower temperature (-214 oC) and raining N2 (boiling temperature of -210 oC) in Neptune was reasoned in this work to strips 15N from the atmosphere of Neptune for explaining its lack of lightning in spite of its similar atmospheric composition but warmer (-193 oC) as Uranus. Such internal charging of Neptunian’s atmosphere by the inability to discharge lightning by the author’s theory is a basis for stronger gravitomagnetic coupling of Neptune to the magnetic field of the Sun. The author thereby explains the disappearance and appearance cycle of Neptune’s clouds by gravitomagnetic coupling of charged clouds of Neptune to 11-year magnetic pole reversal of the Sun!

The Biological Rule that Need to be Followed to Build the Martian Space Station Ecosystem

Authors: Zhengxi Wang
Comments: 7 Pages.

In this paper, the biological survival rule is described, based on which the cause of the failure of Biosphere 2 is analysed at the structural level to find solutions to the existing problems and guide biological practices in the future. The main cause of the failure of Biosphere 2 was that species were not introduced in classes, in order and in a step-by-step manner and not in sufficient time. A solution for establishing a biosphere involves step-wisely introducing species in the following order: prokaryotes, eukaryotes, plants, animals, and humans. The future Mars ecological engineering project should also adopt the above rule and follow the biological survival rule, starting from introducing prokaryotes and then simple eukaryotes to reproduce the process of biological evolution on Earth, which can also be applied to Lunar bases and space station.

Cancer is a complex disease having a number of composite problems to be considered including cancer immune evasion, therapy resistance, and recurrence for a cure. Fundamentally, it remains a genetic disease as diverse aspects of the complexity of tumor growth and cancer development relate to its genetic machinery and require addressing the problems at the level of genome and epigenome. Importantly, patients with the same cancer types respond differently to cancer therapies indicating the need for patient-specific treatment options. Precision oncology is a form of cancer therapy that focuses on the genetic profiling of tumors to identify molecular alterations involved in cancer development for custom-tailored personalized treatment of the deadly disease. This article aims to briefly explain the foundations and frontiers of precision oncology in the context of ongoing technological advances in this regard to assess its scope and importance in the realization of a proper cure for cancer.

Systems of State Set-Permutated Langton Cellular Automata Replicators Compared with Systems of Byl Replicators

Authors: Perry W. Swanborough
Comments: 7 Pages.

Methods applied to the Byl cellular automata (CA) replicator (1989) which demonstrated strict homochirality and functional heterochirality of replication were applied to the earlier Langton CA replicator (1984). Langton replicators varying by state set permutations group into systems of two members each, replicating under a single system-specific cell state transition function. Notably, the Langton systems are smaller than the homochiral Byl replicator systems of three or four members. There are fundamentally two Langton systems distinguishable by the non-existence of permutation transforms which interconvert either one to the other, so in one sense there is non-trivial state-set permutation variation in the set of permutated Langton systems that does not exist in the set of permutated Byl systems.

Finger Temperature Fluctuations of a Covid-19 Patient

Authors: Wei Qiang
Comments: 6 Pages.

In recent years, studies have found that rapid temperature fluctuations can be observed by measuring and recording infrared temperature on different fingers even if the patient does not alternate between feeling hot and cold. After the COVID-19 epidemic spread widely in China, a similar result was also found in a COVID-19 patient: the infrared temperature on the ulnar side of the ring finger and the radial side of the little finger appeared to fluctuate with an amplitude greater than 0.5 degrees every minute. At this time, the temperature of other fingers (including the ulnar side of the little finger) fluctuated only slightly or did not fluctuate at all. In addition, as the condition changed, the aforementioned phenomenon disappeared, and the infrared temperature curve on the radial side of the thumb changed slowly and greatly, but the infrared temperature changes in the other fingers were much smaller. These phenomena are difficult to explain in terms of thrombus or changes in blood temperature/flow velocity. In contrast, it may be more reasonable to assume that the heat generated by Qi changes when the flow of Qi is obstructed.

Systems of State-Set Permutated Replicators Walking Ergodically and Non-Ergodically in Permutation Space

Authors: Perry W. Swanborough
Comments: 14 Pages.

In this paper I describe collections of state-set permutated Byl replicators replicating under common state-transition functions as systems of replicators, and show that systems can be walked through a permutation space by replacement or deletion and addition of system members. By doing this, a process of homochiral replication systems exploring an "adjacent possible" is modelled. Ergodicity corresponds to the maximum possible number of replacements in a system at some or all steps, but assuming gradualism of system change by limiting the number of changes in each step to the minimum possible, walks within the comprehensive permutation space become restricted in range.

Second Level Code of Life: Existence and Role of Protein Program

Authors: Bo Zhang
Comments: 19 Pages.

The traits of an organism are determined by DNA or RNA genetic information. Based on modern genetic theory, such determination path is from genetic information to proteins’ structures, proteins’ functions, then to traits or abilities of an organism. However, the microscopic activities of life molecules in many phenomena and functions of specific proteins are not well explained only by the structures of proteins and other life molecules.I propose a classification of rules that things operate in accordance with which includes rules of natural laws, rules of structures and rules of information codes. Then I infer a new concept model of life, namely, genetic program of genetic substance molecules that are the second level code of life, the inference is based on modern genetic theory and the concept of the three types of rules. Genetic program is carried and executed by genetic substance molecules including DNA, RNA and proteins and define certain rules of action of life. The protein program is now the mainstay of the genetic program. And the protein’s role as the information substance of life is examined in this paper on this account.The theory provides new perspective and justifications to explain activities of biomolecules and biological functions. I also give a new definition of life based on the concept of the genetic program: A life is a body that contains molecules carrying genetic program, at least one of the molecules haven’t lost the ability to execute its genetic program.

Exobiological DNA 1bna based on Silicon

Authors: Ricardo Gobato, Abhijit Mitra, Sufia Zaman
Comments: 7 Pages.

The Silies has been investigated as a possible al-- the DNA double helix - sometimes doubles up again. Researchers have now found this quadruple-stranded form in healthy human cells for the first time. Speculate that the quadruplex structure forms to hold the molecule open and facilitate the reading of the genetic code and thus the production of proteins. G-quadruplex DNA is a four-stranded structure made that can form a ’knot’ in the DNA of living cells. In these terms, it was analyzed through computationalcalculations, via MM(Molecular Mechanics), and byab initio Restricted Hartree-Fock (RHF) method, on a simple STO-3G (Slater-type orbitals with 3 Gaussians) basis, the possibility of a DNA macromolecule based on Silicon. From the basic structure of 1bna, however, you assume conditions without the presence of Carbon, replacing it with Silicon. It was obtained a cluster of G-quadruplex DNA, forming a cocoon, with great possibility for the pharmaceutical industry in capturingmolecules foreign to human DNA.

Photophosphorylation Generates Evolutionarily Compromised Adenosine Triphosphate With a Central Role in Energy Transduction to Operate Open Systems (In Spanish)

Authors: Alfred Bennun
Comments: 21 Pages. (Correction made by viXra Admin - Please conform!)

La investigación pionera en la estructura y función de los sistemas de membranas enzimáticas, que están acopladas a fuentes de energía, podría eludir el principio de reversibilidad microscópica y permitir la emergencia-desarrollo de un mecanismo de cinética vectorial. La investigación sobre el mecanismo de los sistemas acoplados implicó el aislamiento de CF1-ATPasa purificada y la reconstitución de fotofosforilación por adición a la membrana residual, conteniendo los fotosistemas I y II. Adicionalmente, se obtuvo el desacoplamiento y reconstitución de las ATPasas dependientes de la luz (light-dependent) y activadas por la luz (light-triggered) en un porcentaje similar a la reconstitución de la fotofosforilación con la membrana residual. La enzima aislada y luego purificada también se investigó como una enzima funcional oscura mediante activación hasta tripsina o tratamiento térmico. Además, se investigaron los requisitos del mecanismo del modelo, que requiere un nivel de física microscópica y/o mecánica cuántica para demostrar una participación en la transducción de energía. Este enfoque involucró los vínculos con los estados de excitación y los mecanismos de los fotosistemas I y II descriptos por muchos otros investigadores. La interpretación de modelos utilizando el mecanismo de ruptura de puentes de H en la configuración del potencial de acción de masas por la alta molaridad del cúmulo de agua permitió un desplazamiento lejano del equilibrio, funcional al sistema abierto, asegurando la irreversibilidad del sistema completo. Se propusieron moléculas de agua que carecen de puentes de H para actuar como portadores disipadores de entropía. Los mecanismos homeostáticos de temperatura se aplicaron para el cerebro humano. Independientemente de las diferentes propuestas, se enfatiza que se ajustan los requisitos para operar la vida como un sistema abierto. La propuesta de implicar en un rol general de la transición de estado del agua en lugar de describir específicamente cada reacción conduce a evaluar el potencial disipativo del clúster de agua (H2O)n para interactuar con las asimetrías hidrofílicas (para entalpía) vs hidrofóbicas (para entropía), y restringir la aleatoriedad (caos) al dar unicidad al sentido cinético. Así, interpretar su acción como si constituyera un solo pico, consolidando su rol operativo como energía de activación (Ea). Las capas de hidratación podrían actuar en secuencia como un potenciador difuso de contribución específica para obtener Ea de la totalidad del sistema, incluso como entrada en varios picos que activan secuencialmente estados de transición.

El efecto Doppler podría aplicarse a la conectividad neuronal direccional que implica un cambio en la frecuencia ν±Δν de la onda que se mueve en relación con la fuente de la onda, actuando sobre el distanciamiento del circuito neuronal. El orbital 1s del átomo de hidrógeno permite que el espín del electrón suba y baje para emitir a 18 cm del radical hidroxilo y 21 cm de hidrógeno atómico, que combinados forman agua.Esta línea espectral más fuerte del hidrógeno, presente en la Edad Oscura y detectada por radioastronomía desde las galaxias primordiales. Es también emitida por el agua de todos los tejidos, médicamente aplicada para estudios cerebrales, por resonancia magnética (MRI). Por lo tanto, una imagen oscilante del efecto Doppler de la dinámica de distanciamiento-acortamiento permite la conectividad neuronal por sus frecuencias de espectro de emisión.Por lo tanto, el ensayo de coherencia a escalas nanométricas o termodinámica de distanciamiento, equivalente a la fuerza de plasticidad del movimiento neuronal para la conectividad eléctrica. Por lo tanto, su medida de interpretación era equivalente al diálogo (crosstalk) entre neuronas y su elucidación se convirtió en un análogo a una sincronización a un nivel quántico (Truncated by viXra Admin)

The Doppler effect could be applied to directional neural connectivity that implies a change in the frequency ν±Δν of the moving wave relative to the source of the wave, acting on the distancing of the neural circuit. The 1s orbital of the hydrogen atom allows the electron spin to bob up and down to emit 18 cm of the hydroxyl radical and 21 cm of atomic hydrogen, which combined form water.This stronger spectral line of hydrogen, present in the Dark Ages and detected by radio astronomy from primordial galaxies. It is also emitted by the water of all tissues, medically applied for brain studies, by magnetic resonance imaging (MRI). Thus, an oscillating Doppler shift image of the distancing-shortening dynamics enables neural connectivity by their emission spectrum frequencies.Therefore, the assay of coherence at nanometer scales or distancing thermodynamics, equivalent to the force of plasticity of neuronal movement for electrical connectivity. Therefore, its interpretation measure was equivalent to the dialogue (crosstalk) between neurons and its elucidation became an analogue to a synchronization at a quantum level.

A Comprehensive Identification of Coexisting Cellular Automata Replicators Varying by State-Set Permutations.

Authors: Perry W. Swanborough
Comments: 7 Pages.

A study to determine state-set permutated replicators of opposite handedness coexisting with John Byl’s 1989 replicator subsequently suggested the task of identifying the comprehensive set of all left- and right-handed state-set permutated replicators coexisting with the Byl replicator. This work reports the lists of both left- and right-handed state-set permutated replicators coexisting with replication of the original Byl structure replicating under Moore state-transition rules, and as such supplements previous work described in viXra:2101.0075 and viXra:2107.0172.

The Cosmos Thermodynamics Axis Manifests Decoherence That Integrates Into a Multi-level Space-metrics for Coherence for Brain Function

Authors: Alfred Bennun
Comments: 74 Pages. 18 figures, 1 table

The Doppler shift could be applied to directional neuronal connectivity involving change in frequency ν±Δν of wave that is moving relative to the wave source, acting over neuronal circuit distancing. The 1s orbital of the hydrogen atom allows the electron spin-flip up and down to emit radio emission at 18cm from hydroxyl radical and 21cm atomic hydrogen, which combined form water. This strongest spectral line of the hydrogen, present in the Dark Ages and by radio astronomy detected from primordial galaxies, is emitted by the water of all tissues, medically applied for brain studies, by magnetic resonance imaging (MRI). Hence, a Doppler Effect imaging of the distancing dynamics allows neuronal connectivity by their emission spectrum frequencies. Hence, the assay of nano scales coherence or distancing thermodynamics, equivalent to the plasticity strength of neuronal movement for electric connectivity. Therefore its interpreting measure an equivalent of crosstalk between neurons and its elucidation became an analog to a translation of this unknown process. The transmembrane enzymes generate the enthalpy, coupled to the metabolism of glucose and water cluster. The products CO2 and water as vapor are exhaled at the mouth as entropy. This integrative model allows a joint perspective of multiple layers of the reality, conditioned by scale dimension. Thus, the metrics of the quantum mechanics realm could show the locals frames for superposition of space and simultaneity. The brain thermodynamics relationship between inputs of glucose and the enthalpy process of metabolic energy (heat), coupled homeostatically at 36.6℃ to water cluster H-bond breakdown, which in the cerebrospinal fluid (CSF) flow in microtubules could circulate in a liquid state as dimers (H2O~OH2) to dissipate entropy as vapor in the oral cavity. The multi-layers at neuron scale manifest spin in antenna role to signal connectivity for axon, dendrites, microtubules and tunneling. Myelinated space is a thermodynamic closed system, which eventually tends to equilibrium between enthalpy and entropy in which free energy cannot produce work. At a myelinated axon the Nodes of Ranvier "jumps" from node to node operate the unmyelinated stretches as a nano open space-time system. Quantic thermodynamic allows a repetitive sequence at the nano level of close to open, close to open, close u2026 Hence, a maximal value of enthalpy is conserved and entropy became dissipated outside the system, maintaining the action potential level in steady state.

Numbering of the Twenty Proteinogenic Amino Acids

Authors: Jean-Yves Boulay
Comments: 40 Pages.

By proposing a numbering of the twenty proteinogenic amino acids deduced from the physicochemical properties of the four coding DNA nucleobases, it is established that this amino acid number, equal to 5x entities, is not arbitrary. Indeed, we demonstrate that many attributes of these twenty amino acids, as a whole, are also 5x in number and that by isolating, since their numbering, the 3x peripheral amino acids from the 2x internal ones, these attributes are divided into ratios of 3/2 as exact value. This is verified both as the physicochemical properties of the 20 amino acids and as the coding configurations of the nucleobases, the source of this numbering.

Neurons and Electromagnetic Waves

Authors: Zuodong Sun
Comments: 13 Pages.

Based on the potassium channel "origami windmill" model, and the conservation law of cell membrane area and ion inequality equation of based on the potassium channel "origami windmill" model, and Maxwell's electromagnetic theory, it is theoretically proved that neurons can generate electromagnetic waves. The electromagnetic wave is an energy wave, never disappear. The neurons are equivalent to the built-in antennas of the brain, and information transmission between neurons is conducted wirelessly. The material basis for neurons to generate electromagnetic waves is the result of the exchange of cations on the inner surface of the cell membrane, especially Na+ and K+； The essence of consciousness should be electromagnetic wave. The conclusion that "neurons can produce electromagnetic waves" overturns the view that "electricity→chemistry→electricity" conducts information between neurons, and provides theoretical support for humans to finally solve the mysteries of the brain. At the same time, seven falsificationist methods are given. The brain is a huge gold mine, and it is too important to crack the mystery of the brain. It should be a joint operation of "multiple arms". It should not only be the work of brain scientists, but also the participation of physicists, chemists and mathematicians.

Does Replication in Cellular Automata Spaces Always Correspond to Broken Symmetries?

Authors: Perry W. Swanborough
Comments: 10 Pages.

The Noether theorem establishes that symmetries in physics correspond to conservation laws, and therefore contra-positively that un-conserved quantities correspond to broken symmetries. This theorem was not established for dynamic systems in discrete space and discrete time, but the author in previous work has observed that replication of published cellular automata (CA) loop structures corresponds to chiral asymmetries. The work described here shows that replication of a different kind of CA replicator (the HighLife replicator of Nathan Thompson, 1994) corresponds to loss and restoration of a line of symmetry in each replication cycle. In addition to my past observations of loop replication chirality, the broken symmetry observed in the achiral replication of the achiral Thompson replicator suggests a hypothetical general principle of a correspondence between replication observed as an un-conserved (increasing) number of replicator instances and a range of broken symmetries. The paper concludes with some speculation about the possible relevance of simple CA replicators to proto-biology.

Censorship and Active Suppression of Science and Medicine: Censorship exercised on scale during the Covid-19 pandemic has actively suppressed the wide circulation of legitimate scientific inquiry, critical analysis and discussion. Together with the vaccination failure itself, as foreshadow by Judy Wilyman, the officially sanctioned censorship is now the No.1 issue of our time. It has involved the lockstep behaviour of BigPharma, main stream media, BigTech, governments, peak medical, scientific and public health authorities. How did this happen? What are the well spring roots of this extraordinary co-ordinated active suppression of legitimate alternative viewpoints and data analysis in science and medicine?

A Protein Hydrophilic Active Site Could by Mutual Exclusion Became Hydrophobic, Allowing This Vectorial Transition to Bypass the Microscopic Reversibility Principle

Authors: Alfred Bennun
Comments: 22 Pages. 9 figures

Prigogine proposed a coupling between larger sources of enthalpy to allow an open system to operate life. The sun flow of energy is coupled to water cluster thermogenic breakdown of H-bonds to vapor. The position of proline in a polypeptide chain allows sliding between segments, in the tertiary folding structure response to electrostatic attractions, could differentiate positive vs negative domains. Thus, bypass the microscopic reversibility principle, illustrated as a single door, vectorial kinetic only made possible by the jokingly Maxwell proposed operator demons. The physiological function of Hb oxygenation by pO_2 shows a microscopic thermogenesis biological vector, functioning by the enthalpy potential of the large mass action of surrounding air and releasing entropy. The mechanism shows the H-bonds breakdown required for changes in the structure-function levels by the proline mediated folding. The tense (T) to relax (R) forms shows vectorial microscopic dynamics, during Hb oxygenation. Thus involves a sliding by H-bonds breakdown, distancing between subunits β_2 and α_1. Thus, open a larger entrance to a fully hydrated Mg^2+ to coordinate amphoteric and negative R groups characterizable to a hydrophilic site. The transition of R to T allows positive R groups to bind 2,3-DPG to form deoxyHb. Thus, a microscopic smaller entrance by decreasing its opening size does not allow entrance of the fully hydrated Mg2+, but allow the exit of nitric oxide (NO) and a poorly hydrated Mg^2+, denominated nascent. This one acts for competitive hydration sieving on the shells of Na+, which in terms take water from the K+ shell, potentiating a K+/Na+-translocation operating the electrogenic transmembrane potential. The deoxygenation in the reverse transition of R to T binds NO, protecting against a premature decrease of the chromosome’s telomeres size by stressing factors such as depression, anxiety and physic traumatisms, over endothelial cells delaying premature senescence. The arginine metabolism produces NO, dilating blood vessels, improving the circulatory systems and the muscular recovery-development. A diet rich in arginine by producing a high sustainable level of NO may prevent the resistance to treatment by the consolidation of large vascular masses. The H-bonds donor potential by their breakdown leads to randomness (or entropy) decreasing the kinetic energy of solvation, scaling down the polarity on the thermogenic dissipation of oxy vs deoxyHb and choroid plexus epithelium on plasma generation of cerebrospinal fluid (CSF). The enthalpy of photosynthesis-metabolism releases CO_2, whereas the water cluster mediated thermostatic function releases vapor. In both systems, the entropy release maintains a high potential of enthalpy. Hence, overcomes the thermic and electric noises by an irreversible dissipative kinetics, facilitating a clear development of a meditative level of reasoning and learning. Thus, the brain acquires an autonomous function, beyond behavioral genetic conditioning.

Living Cell’s Feeling of Holes: The Mathematics of Cavities in Biophysical Structures

Authors: Arturo Tozzi
Comments: 10 Pages.

Mechanical properties such as shape, volume and size affect the dynamics of biological systems. Most of the current methodological approaches are inclined to remove the existence of holes and impurities from systems’ description, regarding them as routes toward mechanical failure. On the contrary, we suggest that the occurrence of holes might be of utmost functional importance, allowing reversible transformations of cellular structures. The focus here is on the widespread occurrence of intracytoplasmic holes, that deeply modifies the topology of living cells and provides researchers with novel operational tools to investigate intracellular dynamics. We take as example the prokaryotic gas vesicles, i.e., intracellular cavities filled with gases spreading from the nearby medium. The mechanical and topological cellular properties dictated by intracytoplasmic holes are investigated, focusing on the physical constraints imposed by their very existence. For instance, the presence of gas vesicles breaks the cytoplasmic homogeneity, leading to inhomogeneity in functional activities and modifications in intracellular flows. Also, a topological approach to cytoplasmic holes suggests novel physiological roles for gas vesicles. For example, the gas vesicles’ ability to increase/decrease cellular volumes provides a mechanism that counteracts the detrimental effects of the surface/volume ratio. In conclusion, a structural/methodological approach based on the occurrence of holes testifies once again how the simple biophysical structure alone can dictate the function.

Photophosphorylation Generates Atp Committed by Evolution to a Central Role in Energy Transduction to Operate Open Systems

Authors: Alfred Bennun
Comments: 19 Pages. 9 figures, 4 tables.

Pioneering research in the structure and function of enzyme membrane systems, which are coupled to energy sources, could bypass the microscopic reversibility principle, and allow the emergence-development of a mechanism for vectorial kinetics. The research on the mechanism of coupled systems involved the isolation and reconstitution of the purified CF1-ATPase with the residual membrane. Photophosphorylation involves coupling with photosystem I and II, which by uncoupling show a light-dependent and light-triggered ATPases. The isolated and then purified enzyme was also investigated as a dark functional enzyme by activation through to trypsin or heat treatment. In addition, were investigated the requirements of model mechanism, which requires microscopic physics or/and quantum mechanics level to demonstrate an energy transduction participation. This approach involved the links to the excitation states and mechanisms of photosystem I and II discovered by many other investigators. The interpretation of models using the mechanism of H-bond breakdown in the configuring of the mass-action potential by the high molarity of the water cluster allowed a faraway displacement of equilibrium to the parameter ensuring irreversibility of the system. H-bond lacking molecules of water were proposed to act as dissipative carriers of entropy. However, homeostatic temperature mechanisms could be developing for brains, which are under discussion. Independently of different proposals it is emphasized that fit requirements to operate life as an open system. The proposal to implicate in an overall general role of the state transition of water rather than described specifically every reaction lead to evaluate the dissipative potential of water cluster (H2O)n to interact with the hydrophilic vs hydrophobic asymmetries, which restrict randomness of in the singleness of kinetic sense. Thus, interpret its action as if it constitutes a single peak, consolidating its operative role as is activation energy (Ea). The hydration shells could in sequence act as a diffuse enhancer of specific contribution to obtain Ea of the totality of the system even as an input into several peaks that sequentially activate transition states. Hence, changes in dipole state, sliding, pKa, n-H-bonds, etc., could become concatenated for vectoriality. (H2O)n by the loss of H-bonds coupled with the hydration turnover of proteins and ions to result in incomplete water cluster (H2O)n*, with a lower-n. (H2O)n* became a carrier of heat/entropy.

Integration of Bioinspired Artificial Channels for the Concept Design of an Artificial Kidney Device

Authors: A. Alayoud
Comments: 23 Pages.

Recently, there has been a great interest in the possible applications of synthetic transporters that mimic the structures and functions of natural ion channels for liquid separations, water purification, and biosensing. Here we propose, for the first time, the use of selective polymer membranes incorporated by synthetic artificial carriers combined with existing dialysis technologies to create a synthetic nephron. Consistent with renal physiology, the proposed system has 3 distinct sections, replicating the glomerular filtration and tubular functions (secretion and reabsorption) and may represent a breakthrough in renal replacement therapy based on the functioning of native kidneys. Thus, this design can be used to manufacture a dialysis machine, with technical features capable of allowing dialysis treatment without ultrapure water or concentrate.

The Axon: Restructuring Waves and Electrical Currents

Authors: Lev I. Verkhovsky
Comments: 7 Pages.

An article “The Brain, Reimagined,” by Douglas Fox (Sci. Am.,v.27, No 3, Fall 2018) concerns work by physicists T. Heimburg and A.D. Jackson, who argue that signals in neurons are conveyed by mechanical waves of expansion and contraction of the cell membrane rather than by electrical spikes, or action potentials, as described by the Huxley-Hodgkin theory. But the chief provisions of this theory are firmly established. Hypothesis on the honeycomb structure of the lipid biomembrane by Dr. R.-H.N. Mikelsaar makes it possible to remove the contradictions between these two concepts.

Overview SARS-CoV-2 Pandemic as January 2022: Cometary Origin, Global Spread, Prospects for Future Vaccine Efficacy

As the SARS-CoV-2 pandemic is nearing its eventual end we focus on what we believe are two key omissions from the mainstream scientific literature and which have significant implications for how mankind manages the next global pandemic. We review data, observations and conclusions from our papers published 2020 and 2021 on its likely cometary origin and global spread. We also revisit the superior effectiveness of intra-nasal vaccines against respiratory tract pathogens. While these two oversights seem disparate, together they provide us with new insights into our collective awareness of how we might view and address the next global pandemic. We begin with our hypothesis of its likely cometary origin via a bolide strike in the stratosphere on the night of October 11 2019 on the 40o N line over Jilin in NE China. Further global spread most likely occurred via prevailing wind systems transporting both the pristine cometary virus followed by continuing strikes from the same primary source as well as prior human passaged virus transmitted by person to person spread and through contaminated dust in global wind systems. We also include a discussion of our prior work on data relating to vaccine protective efficacy. Finally we review the totality of evidence concerning the likely origin and global spread of the predominant variants of the virus ‘Omicron’ (+ Delta mix?) from early to mid-December 2021 and extending into the first week January 2022. We describe the striking data showing the large numbers of infectious cases per day and outline the scale of what appears to be a global pandemic phenomenon, the causes of which are unclear and not completely understood. We discuss a number of mechanisms and explanations for this striking coo-ordinated global phenomenon. We conclude with an optimistic note for mankind. Given our prior knowledge on the effectiveness against respiratory tract pathogens of mucosal immunity involving induction of dimeric secretory IgA antibodies, we consider the recently published intra-nasal vaccine data from laboratories based at the University of California, San Francisco and, independently at Yale University, holds great promise for the future development of both pan-specific and specific immunity against future pandemics caused by suddenly emergent respiratory pathogens, whether viral and bacterial.

The Quantum Motion of the Nerve with an Interstitial Defect

Authors: Miroslav Pardy
Comments: 7 Pages. Original article

We consider the nerve as the elastic string, the left end of which is fixed at the beginning of the coordinate system, the right end is fixed at point l and mass m is fixed between the ends of the string. We determine the classical and the quantum vibration of such system. The quantum motion is obtained by the so-called non-conventional oscillator quantization method by author. The proposed model can be also related in the modified form to the problem of the Moessbauer effect, being the recoilless nuclear resonance uorescence, which is the resonant and recoil-free emission and absorption of gamma radiation by atomic nuclei bound in a solid. (Mossbauer,1958). It is not excluded that our oscillator quantization of the string can be extended to generate the new way of the string theory of matter and physiology of nerves.

Development of a Two-Dimensional Replicator from a Single Non-Quiescent Cell in Cellular Automata Space

Authors: Perry W. Swanborough
Comments: 7 Pages.

Two hard problems in the origin of life question are identification of the structure of biology’s ancestral replicator(s), and the emergence of replicators from a prebiotic environment. In the discipline of cellular automata (CA), not all CA abstractions of replication include any origin pathway to the replicating structures. In this work, an origin for the J. Byl (1989) CA replicator from an isolated non-quiescent cell is described. This origin pathway requires introduction of one oriented state and three other states, all of which permanently disappear from the subsequent replication process. Origin of the replicator and subsequent replication display three sequential and spatially-expanding domains of counter-clockwise rotation: the oriented state of a single cell rotates as the first replicator structure develops around it, followed by rotation of the 2x2 cell information loop as a replication cycle proceeds, and in subsequent cycles of replication, orientation of a parent replicator also rotates counter-clockwise as directions of replication are successively blocked by the replicator’s children.

Evolutionary Elongation of Purine Stretches in the Genome and Their Possible Role in Resonance Signaling

The concept of electromagnetic signaling in biological tissues has been around almost since Hertz's experiment proving the existence of electromagnetic waves. Although electromagnetic signaling would better explain the speed and precision of the work of the genome and coordination between the cells than chemical signaling, molecular mechanisms and experimental evidence for it are insufficient. Recently, we proposed that DNA, being the central program of life and a very stable substance, is directly involved in electromagnetic signaling and that its sequences harbor sequence-dependent electromagnetic oscillators. We also proposed two types for sequence-dependent electromagnetic oscillation - the ones that include delocalized negative and positive charges. The first type is proposed to occur in purine stretches in DNA, i.e. stacks of purine bases (A and G) with electron clouds delocalized within stacked aromatic rings. Here, we utilized the public data on genetic variations in genomes of several biological species to test the evolutionary pressure on the length of purine stretches. The single nucleotide polymorphism (SNP) replacing a purine with pyrimidine would disrupt the purine stack and the corresponding delocalized electron cloud and thus impact its oscillation frequency. As a result, it was demonstrated that there is a consistent evolutionary pressure towards the elongation of purine stretches in the genomes of the human and all other tested species. Additional analysis demonstrated that this pressure is independent of the bias caused by unequal chemical nucleotide lability and is therefore genuinely caused by the functional evolutionary advantage of longer purine stretches. This offers additional support for the proposed mechanisms of electromagnetic signaling in the genome.

Oscillations in Hypothalamic-Pituitary-Adrenal Axis

Authors: Igor B. Krasnyuk, Andrey E. Zabolotin
Comments: 23 Pages.

A structured model of the HPA axis that includes the glucocorticoid receptor (GR) is considered. The model includes nonlinear dynamics of pituitary GR synthesis. The nonlinear eect arises from the fact that GR homodimerizes after cortisol activation and induces its own synthesis in the pituitary. This homodimerization makes possible two stable steady states (low and high) and one unstable state. The model includes also delay on stress. It is shown that concurrence between trajectories of dynamical system, which are produced by the unstable manifold and the value of delay time τ produce slow oscillating asymptotic periodic oscillations of cortisol with a period, which is grater then 2τ. It is shown that such oscillations exist only in an interval τ1 < τ < τ2 , where exact formulas for τ1 and τ2 has been obtained. Such oscillation arise when an initial values of stress are lager of some threshold.

We have set out to assess the data on the intensity of the COVID-19 pandemic with a view to making plausible predictions of its decline. A plot of “ % COVID-19 Associated Death per Day” versus the timing and extent of the roll out of national vaccination campaigns in Sweden, Denmark, Netherlands, United Kingdom, France, Germany, Italy and USA shows that the decline in the severity of the COVID-19 pandemic was well advanced noticeably before vaccinations began or could have become a significant contributory factor. Israel is an outlier in its manifest decline pattern, yet the data also demonstrate that vaccination has had no discernible impact at all on % Deaths per Day in Israel.

The Relevance of the Significant Reduction of X-ray Dose while Increasing the Resolution of Diagnostic Radiology

Authors: Avsharov Evgeny Mikhailovich
Comments: 9 Pages. In Russian

Currently existing approaches to the construction of x-ray diagnostic systems do not allow to combine in one product characteristics such as: - reduce x-ray dose by an order of magnitude, - reduction f the focal spot x-ray tube to a value of 0.1*0.1 mm and less in the millisecond time shooting the x-ray image; - decrease integral radiation power of the image frame coinciding with the period of radiation without increasing the instantaneous power of x-ray tube; - increasing resolution, dynamic x-ray detectors with a simultaneous increase in the speed of frames per second; - reducing the value of the ratio signal/noise and to increase the resolution of diagnostic images through mathematical processing of images. The output from the system of constraints is only possible through the creation of a new class of x-ray diagnostic systems, built on technology “Microsecond Radiology”, which incorporates the best of all three rentgenologii – Standard, Microfocus and Nanosecond rentgenology.

Instances of Functional Heterochiral Replication of the J. Byl Structure Supported by Two State-Set Permutations

Authors: Perry W Swanborough
Comments: 7 Pages.

Previous work demonstrates that strict heterochiral replication of self-replicating loops in two-dimensional cellular automaton space is not possible under any single cell-state transition function, but a less-strict functional heterochirality is possible with the introduction of a different broken symmetry: a cell state-set permutation applied exclusively to left- (or right-) handed replication. A new result reported here is that up to two different state-set permutations applied to one replication chirality can support functionally-heterochiral replication of the J. Byl self-replicating structure in one common cellular automata space.

The possible role of DNA sequence-dependent electromagnetic resonance in the formation of the morphogenic field is discussed. It is hypothesized that the basis of the morphogenic field is the resonant oscillations of clouds of delocalized electrons and protons in the stack of DNA bases, and that genomic repeats serve as universal resonators that provide two-way transfer of information between chromatin structures and the morphogenic field. The proposed algorithm for the resonant transformation of genomic information into the structure of the organism mediated by the morphogenic field is named "the DNA resonance code", and approaches to its decoding based on a combination of biophysics, spectroscopy, and experimental and computational genomics are proposed.

Applying "Ab Initio" Hartree-Fock Methods to Exobiological Nanomolecules

Authors: Ricardo Gobato, Alireza Heidari, Lauro Figueroa Valverde, Abhijit Mitra
Comments: 6 Pages. Exobiology

he core of the work is based on the replace- ment of carbon atoms by silicon atoms, on the basis of four standard bases of DNA: A, C, G and T (adenine, cytosine, guanine, thymine). Determining with minimum computational methods via "ab initio" Hartree-Fock methods, infrared spectrum and their peak absorbance frequencies. The option for simple replacement of carbon by silicon is due to the peculiar characteristics between both. Atomic interactions under non-carbon conditions were studied, with only the Hydrogen, Silicon, Nitrogen and Oxygen atoms, in STP (Standard Temperature and Pressure), for the four standard bases of DNA, A, C, G and T, thus obtaining by quantum chemistry four new compounds, named here as: ASi, CSi, GSi and TSi. Computational calculations admit the possibility of the formation of such molecules, their existence being possible via quantum chemistry. Calculations obtained in the "ab initio" Unrestricted and Restrict Hartree-Fock method, (UHF and RHF) in the set of basis used Effective core potential (ECP) minimal basis, UHF CEP-31G (ECP split valance) and UHF CEP-121G (ECP triple-split basis), CCpVTZ (Correlation-consistent valence-only basis sets triple-zeta) and 6-311G**(3df, 3pd) (Gaussian functions quadruple-zeta basis sets).

Therefore, the idea that the biofield is created by the mass of DNA in the organism remains a hypothesis. We will first briefly summarize the existing evidence and then briefly review our studies, in which we used computational genomics to reveal the traces of resonance signaling in the genome and provided statistical evidence for this resonance signaling.

Thought is force. Thought force can be detected by thought force sensor. If we place two thought force sensors in two separate DC circuits and we connect these circuits with a single-wire without return, we get an unorthodox DC circuit. Here, the two DC circuits are not closed in the ordinary acceptance of the term, yet both thought sensors can be controlled with the same thought force via the single-wire. This is only possible, if current flows in two different directions simultaneously in the single-wire without return that connects the two DC circuits.

Functional Heterochirality of Replication of the J. Byl Self-Replicating Structure: A Moore Rules State-Transition Function and Cell State-Set Permutations.

Authors: Perry W Swanborough
Comments: 16 Pages.

Heterochiral self-replication of loop structures in cellular automata spaces cannot be achieved by pooling a state-transition function supporting self-replication with its corresponding mirror-transformed transition function because some chiral rules specific to right-handed replication are contradicted by chiral rules specific for left-handed replication. In a subsequent study, a less-strict functional heterochirality of self-replication, notionally achievable by application of state-set permutation-transformation to structures and state-transition functions was investigated. Although this strategy reduces the number of rule contradictions between left-handed and right-handed self-replication, state-set permutations applied to left-handed replication do not enable functional coexistence of left- and right-handed self-replication. This work describes the consequences of rewriting von Neumann state-transition rules as a larger set of corresponding Moore state-transition rules. It was observed that there are less state-transition rule contradictions between left- and right-handed self-replication under the Moore rules state-transition function. The observations that state-set permutation-transformations and Moore state-transition rules independently reduce rule contradictions between left- and right-handed self-replication suggested the hypothesis that both strategies implemented together may reduce rule contradictions between left- and right-handed self-replication to zero, enabling functional coexistence of left- and right-handed self-replication. This work reports success in implementing functional coexistence of left- and right-handed self-replication of the J. Byl structure (1989) by application of a Moore rules state-transition function, and any one of six state-set permutation transformations applied to left-handed self-replication.

How Schrödinger's Mice Weave Consciousness

Authors: Max Myakishev-Rempel, Ivan V. Savelev
Comments: 20 Pages. [Corrections made by viXra Admin to conform with scholarly norm]

This paper continues the series of papers on DNA resonance signaling. Previously the authors proposed that DNA is involved in the work of mind directly and immediately via the network of optical fibers. The authors proposed the mechanism of signal transduction in DNA via a sequence-specific resonance between the clouds of delocalized charges in the base stack. It was computationally demonstrated that certain repetitive patterns of delocalized charge clouds were evolutionarily enriched in various genomes. Here, the authors propose that natural quantum computation in DNA in living cells is based on the tautomerization of basepairs and involves coordinated oscillations of hydrogen-bond protons and aromatic electrons. The authors expand the ORCH-OR theory to include the collapse of the wave function of aromatic electrons in purines and propose that such collapses and expansions produce the experience of consciousness and the perception of time. The above mechanisms are supported by an observation that the majority of the psychoactive drugs are aromatic and the suggestion that they modify the aromaticity of DNA by binding to it. Quantum mechanical considerations for the collapse of aromaticity by double proton transfer in basepairs are discussed in terms of the collapse of the wave function, loss of delocalization, and the dynamic balance between coherence and decoherence in DNA.

It is well written and clear, but uneven in parts, particularly absence of a sensible discussion of Hoyle-Wickramasinghe’s Panspermia-Cosmic Biology - the author’s conclusions on the origins of influenza pandemics since the1880s (from 1889 in particular) suffer from not considering all the extant evidence for Panspermia. The book is in two parts over 565 pages, rich in detailed referencing and notes which begins on page 393. This is a valuable resource.

Rapid Diagnosis of Coronavirus Infection and Protective Equipment

Authors: Vasyl Korniienko, Vasyl Belokrinitsky, Ivan Vikulin
Comments: 11 Pages. in English and Russian

It is known that any matter has a quantum electromagnetic field (QEF) [1], Therefore, the WEF of Earth's stressed matter generates waves of quantum electromagnetic energies (S-radiation), which reveals the origin of geopathic radiation (GR), which, as is well known, cause diseases. For the same reason, electric generators, including solar panels, together with electric current generate quantum currents. Internet technology and satellites transform them into S-radiation, the effects of which, like GR, cause diseases. The orbits of these satellites correlate with the dislocation of coronavirus foci, indicating their involvement in the emergence and development of the pandemic. It is shown that the S-radiated metal of the roof of the car, as well as a person infected with COVID-19, generate S-radiations that infect others. Proposed measures that will increase the effectiveness of quarantines, which will stop the pandemic.

Predictive Mathematical Models of the Covid–19 Pandemic in Ode/sde Framework

Authors: Marcello Colozzo
Comments: 23 Pages. [Non-conforming header blocked by viXra Admin]

This article proposes a viral diffusion model (like Covid-19 pandemic) in the ordinary differential equations (ODE) and stochastic differential equations (SDE) framework. The classic models based on the logistic map are analyzed, and then a noise term is introduced that models the behavior of the so-called deniers. This model fairly faithfully reproduces the Italian situation in today’s period. We then move on to local analysis, arriving at an equation of continuity for what concerns the density of the number of infected in an assigned region. We, therefore, prove a Theorem according to which classical logistics is the most catastrophic of predictions. In a realistic scenario, it is necessary to take into account the inevitable fluctuations in the aforementioned density. This implies a fragmentation of the initial cluster (generated by “patient zero”) into an N disjoint sub clusters. For very large N, statistical analysis suggests the use of the two-point correlation function (and more generally, n-points). In principle, an estimate of this function makes it possible to determine the evolution of the pandemic. The distribution of the sub clusters could be fractal, exactly as it happens for the distribution of galaxies starting from a homogeneous and isotropic primordial universe, but with random fluctuations in matter density. This is not surprising, since due to the invariance in scale, fractals have a low “computational cost”. The idea that pandemics are cyclical processes, that is, they occur with a given periodicity, would therefore remain corroborated.

The Reason for the Emergence of Primary Foci of the Coronavirus Pandemic and the Fight Against Them

Authors: V. Korniienko, V. Belocrinicky, I. Vikulin, M. Turkin
Comments: 12 Pages.

The origin of the primary foci of coronavirus is unknown, which makes it difficult to fight the pandemic. However, we found that the centers of the pandemic in Euro-Asia are mainly concentrated along the orbit plane of Chinese Internet satellites, and on the American continents - Starlink satellites. This is due to the fact that their radio waves contain waves of quantum electromagnetic energy (S-radiations). It has been shown that the nature of the origin of S-radiations is the same as geopathic radiation (GR), the property of which causes diseases is well known. Therefore, the S-radiations of these satellites can cause coronavirus diseases and primary pandemic foci. Therefore, it is advisable, based on standards, to limit the level of their S-radiations.

Showing Role of Angiotensin-Converting Enzyme 2 in Covid-19 Using Novel Fic-Fac Ratio

Authors: John Yuk Ching Ting
Comments: 13 Pages. Our novel Fic-Fac Ratio can be regarded as a simple mathematical tool to usefully model COVID-19 and help clinicians better understand this deadly infection. This Ratio essentially allows us to relate open problems from Number theory to to COVID-19.

Objectives: We utilize a Case Report of severe acute respiratory distress syndrome (ARDS) from pneumonia together with applications from Fic-Fac Ratio to creatively explain COVID-19’s drug and vaccine developments, and mitigation measures to combat the resulting pandemic (declared by World Health Organization on March 11, 2020). Methods: Diagnostic test ‘Accuracy’ refers to ability of that test to distinguish between patients with disease, and those without. Our novel Fic-Fac Ratio, which is an acronym that stands for Fictitious-Factitious Ratio, is roughly considered as ‘Inverse Accuracy’ with higher Accuracy corresponding to lower Fic-Fac Ratio and vice versa. Regarded as tertiary spin-off from mathematically proving open problems in Number theory of Riemann hypothesis (and explaining two types of Gram points), Polignac’s and Twin prime conjectures; we succinctly outline the derivation of this Ratio. Results: 2003 Case Report of 43 year-old male presenting with severe ARDS due to Bilateral Early Lobar Pneumonia of uncertain viral etiology resulting in death at a small Australian regional hospital. ACE is an acronym that stands for angiotensin-converting enzyme. The functions of ACE and its counterpart ACE2 are outlined. Physiological and pharmacological implications of ACE2 also acting as entry receptor for the coronavirus causing COVID-19 infection are detailed. Epidemiological principles on modelling COVID-19 pandemic with ‘less accurate’ SIR model versus ‘more accurate’ SEIR model are also presented. Conclusions: Controlling COVID-19 pandemic and developing effective COVID-19 drugs and vaccine(s) can be creatively explained using Fic-Fac Ratio. International collaboration is generally required to defeat COVID-19.

Physical Paradigm of Life as a Generalization of Biochemical Conception. A Physical Law Governing Life Origin and Development

Authors: Yuri K. Shestopaloff
Comments: 40 Pages. Previous versions are on https://arxiv.org/abs/1609.09421

The present view of biological phenomena is based on a biomolecular paradigm that development of living organisms is entirely defined by information stored in a molecular form as some genetic code. However, new facts and discoveries indicate that biological phenomena cannot be reduced to a biomolecular realm alone, but are also governed by mechanisms of other nature. These mechanisms, acting in tight cooperation with biochemical mechanisms, define life cycles of individual organisms, and, through this, the origin and evolution of the living world. Here, we present such a physical mechanism (General growth law), which represents a new physical law of nature. It acts at cellular, organ, system and whole organism scale levels, directing growth and reproduction together with biomolecular mechanisms by imposing uniquely defined constraints on distribution of nutrients between biomass production and maintenance, thus defining the composition of biochemical reactions, their change and irreversibility during the organismal life cycle. Mathematically, this law is represented by the growth equation. Using this equation, we introduce growth models and explain division mechanisms for unicellular organisms. High adequacy of obtained results to experiments proves validity of the General growth law and of the new physical paradigm of Life based on this law.

Dinosaurs Could Submerge Themselves and Breathe While Walking in Shallow Lakes, Their Long Necks Really Did Function as Snorkels

Authors: Jeffrey Joseph Wolynski
Comments: 4 Pages.

: It was claimed that a brachiosaurus would suffocate while walking in a shallow body of water because of the pressure of the water. People in the early 1900’s painted dinosaurs walking in shallow bodies of water, as the artist Zdenek Burian did, using its neck as a snorkel. Fast forward, paleontologists claimed that this would not be possible because the pressure in the water would collapse the dino’s lungs, so then they placed dinos above and out of the water. Now we are going back to dinos easily navigating the shallow seas underwater, because of the ancient atmosphere being much denser during the existence of dinosaurs, of 3-5 bar. Brachiosaurus could snorkel because he/she would only be at ~102- 112% ambient atmospheric pressure. Humans can breath at 109%. Some screen shots and pictures are presented to explain.

Evidence for DNA Resonance Signaling Via Longitudinal Hydrogen Bonds

Authors: Ivan Savelyev, Max Myakishev-Rempel
Comments: 12 Pages.

The theory of the morphogenic field suggests that chemical signaling is supplemented by electromagnetic signaling governing the structure and shape of tissues, organs and the body. The theory of DNA resonance suggests that the morphogenic field is created by the genomic DNA which sends and receives electromagnetic signals in a sequence-specific manner. Previously, the authors have proposed the existence of HIDERs, genomic elements that serve as antennas in resonance signaling and demonstrated that they occur nonrandomly and are conserved in evolution. Here, it is proposed that longitudinal hydrogen bonds exist in the double helix, that chains of these bonds form delocalized proton clouds, that the shapes of these clouds are sequence-specific and form the basis of sequence-specificity of resonance between HIDERs. Based on longitudinal hydrogen bonds, a proton DNA resonance code was devised and used to identify HIDERs which are enriched 20 fold in the genome and conserved in evolution. It was suggested that these HIDERs are the key elements responsible for DNA resonance signaling and the formation of the morphogenic field.

Microscope Images Indicate that Water Clusters Are the Cause of Phyllotaxis

Authors: Harry K. Hahn
Comments: 17 Pages. 73 figures

With my study I want to advance a hypothesis that Phyllotaxis is caused by a lattice of Ice-Crystals or large Water Clusters which are stablized (coated) by certain proteins, e.g. special Ice-binding- or Water-Cluster-binding-proteins. The microscopic Image of the remains of an evaporated water droplet shows a phyllotactic pattern that formed during the evaporation of the water droplet on a silicon wafer. This image is a proof that Water itself must be the main contributor which causes Phyllotaxis ! The pysical process Evaporation, and electric charge and coloumb forces caused by evaporation also seem to play a role in the pattern formation and in the precise orientation and positioning of the water clusters in the pattern. Important for the formation of a phyllotactic Fibonacci pattern seems to be a large central Water Cluster, that may have icosahedral MacKay-geometry, consisting of large icosahedral Sub-Clusters formed by the stable icosahedral water clusters (H2O)100 or (H2O)280. Typical cluster numbers of Mackay-Clusters are 13 and 55 which are Fibonacci Numbers ! Additional proof comes from SEM-Images of the Sunflower Capitulum. These images indicate that new primordia are caused by rhombic crystals, which seem to be either ice-crystals or large water cluster crystals that formed with the help of ice-binding proteins or similar. Proof for a physical cause of Phyllotaxis is also provided by a study about variations in the Fibonacci-spiral patterns of twigs of the three “Pinus Mugo“ which shows that the Fibonacci-pattern variation depends on altitude and temperature- /radiation- conditions. With the results of this study I developed an infinite Fibonacci-Number-Sequences-Table that contains all existing Fibonacci-Sequences and all natural numbers. Finally I present a mathematical discovery regarding constant Phi. All natural numbers and their square roots, as well as constant Pi (π), can be expressed by only using constant Phi (1.618…) and the base unit 1.

Three Paradoxes of Thought

Authors: Tamas Lajtner
Comments: 41 Pages.

There are three paradoxes that summarize the working method of thought. 1) Your thoughts change even when they do not change. 2) If you are thinking today what you thought yesterday, you are already thinking something else. 3) In order to remain in one place you should run. To understand the three paradoxes of thought, we have to understand what thought is. Thought is force. This force is a real force that makes impacts on living and inanimate, e.g. thought force creates the brain’s electromagnetic signals. The existence of thought force can be captured by appropriate mechanical and electronic devices, where thought power and energy can be also measured. This study presents some values of thought power and energy measured by the first electric Thought Power Meter in the world. Knowing these values, using devices like this it is possible to control objects like computer, switch on the wall etc. by thought force. The mainstream science refuses to accept the existence of thought force. In the second part of the study a short physics explanation is given that describes how thought force works. This physics necessarily goes beyond mainstream phys-ics giving new definition of time and space. Thought force is in a given size range. Like all forces, thought force also creates its own counterforce. (Thought force itself can also be a counterforce of other forces.) There is no way to understand how thought works without accepting the human experience on thought’s counterforce. The counterforce and other forces in this size range can be created by lining and inanimate (non-living). Saying this, thought force can be created with and even without brains. This new recognition causes the three paradoxes of thought.

Conditions for Stable Equilibrium of the Upright Human Body in the Absence and Presence of External Influence

Authors: Karlo Moistsrapishvili
Comments: 10 Pages. -

Introduction: This paper combines two previous scientific works [1, 2]. It investigates conditions of the equilibrium stability of a cylinder (shaped homogeneous body) in order to study the equilibrium stability of a human body of different proportions. A new method to determine a human body’s common center of gravity is proposed. An optimal bending forward angle at which the degree of the equilibrium stability of an upright standing person reaches its maximum value is defined and relevant conclusions are drawn. In addition, external forces are also introduced, which may disturb the stable equilibrium and cause the body to tumble. The paper also introduces the concept of the coefficient of the stable equilibrium and proposes a formula for its calculation. Finally, a formula is set up to obtain the maximum value of external forces under which the body still maintains the state of equilibrium. Key words: equilibrium stability; common center of gravity; optimal bending; critical angles, stability coefficient, force of gravity, external force, overturning.

Relationship Between Liquid-Liquid Phase Separation and Epigenetic Modification Based on the Boltzmann Distribution

Authors: Fei Xiong
Comments: 9 Pages.

Liquid-liquid phase separation is pervasive in the interior of cells. Elucidating the mechanism of its formation is important both for understanding its physiological function and for predicting prospective drug targets. According to the Boltzmann distribution, we describe a physical relationship between liquid-liquid phase separation and epigenetic modification, suggesting that biochemical metabolism may play an important role in phase separation. It also suggests that liquid-liquid phase separation is universal in the origins of early life because alkaline hydrothermal vents are full of biochemical reactions.

Masks Don’t Work: a Review of Science Relevant to Covid-19 Social Policy

Authors: Denis G. Rancourt
Comments: 13 Pages.

Masks and respirators do not work. There have been extensive randomized controlled trial (RCT) studies, and meta-analysis reviews of RCT studies, which all show that masks and respirators do not work to prevent respiratory influenza-like illnesses, or respiratory illnesses believed to be transmitted by droplets and aerosol particles. Furthermore, the relevant known physics and biology, which I review, are such that masks and respirators should not work. It would be a paradox if masks and respirators worked, given what we know about viral respiratory diseases: The main transmission path is long-residence-time aerosol particles (< 2.5 μm), which are too fine to be blocked, and the minimum-infective-dose is smaller than one aerosol particle. The present paper about masks illustrates the degree to which governments, the mainstream media, and institutional propagandists can decide to operate in a science vacuum, or select only incomplete science that serves their interests. Such recklessness is also certainly the case with the current global lockdown of over 1 billion people, an unprecedented experiment in medical and political history.

Interpretation of Action Potential Generation Mechanism in Cardiomyocytes by Potassium Channel “Origami Windmill” Model

Authors: Zuodong Sun
Comments: 10 Pages.

The study of the action potential of cardiomyocytes is as important as the study of nerve fiber cells. The theoretical basis of the action potential of cardiomyocytes is the ionic theory formed by nerve fiber cells. Its core point of view: the decline phase of the action potential of cells is dominated by K+ outflow. Applying the principle of the K+ channel “origami windmill” model, the mechanism of action potential generation of nerve fiber cells has been reasonably explained, and a point contrary to the ion theory has been drawn: the phase of the action potential decline is dominated by K+ influx. Similarly, applying the principle of the K+ channel “origami windmill” model can also give a reasonable explanation for the mechanism of action potential generation of cardiomyocytes. The difference between cardiomyocyte action potential and nerve fiber cell: In addition to K+, Cl-, Na+, the process of generating cardiomyocyte action potential also involves the participation of Ca2+. Ca2+ inflow in the rising phase will shorten the depolarization time; Ca2+ inflow in the falling phase will prolong the repolarization time. K+, Ca2+ space substitution proportion: rotate into 2 K+, squeeze out 3 Ca2+, and 4 extra negative charges in the cell, the proportion is 2: 3: 4; Conversely, squeeze out 2 K+, rotate into 3 Ca2+, 4 extra positive charges the cells, the proportion is 3: 2: 4. Na+, Ca2+ space substitution proportion: rotate into 1 Na+, squeeze out 1 Ca2+, and 1 extra negative charges in the cell, the proportion is 1: 1:1; Conversely, rotate into 1 Ca2+, squeeze out 1 Na+, there is 1 more positive charge in the cell, and the proportion is 1: 1: 1. Application of “origami windmill” model principle, can reasonably explain the cardiomyocytes action potential generation mechanism, further proveding “origami windmill” the model theory, “the theory of dove-like particles”“the theory of braincell activation” of science, also proved that the viewpoint of “action potential descending phase, dominated by K+ internal current” is correct. The scientific and rational interpretation of the action potential of cardiomyocytes has far-reaching impact and great significance to the basic theoretical research and clinical practice of the heart from now on.

Enlightening Point of View Based on Potassium Channel “Origami Windmill” Model

Authors: Zuodong Sun
Comments: 28 Pages.

Applying the K+ channel origami windmill model principle, the whole process of action potential generation of nerve fiber cells and cardiomyocytes is explained reasonably. Its core view is: cell action potential decline phase, dominated by influx of potassium ions. This is contrary to the core idea of the traditional theory—ionic theory. According to ionic theory, cell action potential decline phase, dominated by outflow of K+ ions. In the face of such two opposing views, the author traces back to the source, combing and commenting on the basic theoretical research on the production mechanism of cell bioelectricity generation and the results of classical basic experiments. And a series of enlightening viewpoints are produced：1. Ionic theory has its preexistence deficiency; 2. There are principle defects in GHK equation and H-H equation; 3. Ion channels may “same direction sharing”; 4. Sodium-potassium pumps, calcium pumps and so on May not exist. The thesis's Point is falsifiable. If “cell action potential decline stage, dominated by outflow of K+ ions” can be proved, all the points in this paper will not be true. On the contrary, the series of enlightening views in this paper will inevitably lead to a revolution in the field of life science. The viewpoint of this paper is not only closely related to the causes of human major diseases, treatment principles and methods, but also may have a profound impact on the future research direction of life science researchers. So the author suggests that scholars in the field of life science should re sort out the existing bioelectricity knowledge system—eliminate the false, save the true and clear the source, especially focusing on the papers published by Hodgkin and Huxley in 1952; At the same time, it is necessary to reevaluate the scientificity and scientific value of membrane theory, ionic theory, GHK equation and H-H equation, and put forward new theories based on Bernstein membrane theory, and establishing a new mathematical model of cell action potential.

Conservation Law of Cell Bioelectricity Membrane Area and Ion Inequality Equation Based on Potassium Channel “Origami Windmill” Model

Authors: Zuodong Sun
Comments: 19 Pages.

At present, there are misunderstandings and even subversive errors in the understanding of cellular bioelectricity phenomena. The theory explaining the mechanism of bioelectricity generation is the ionic theory, and the ionic theory is based on the membrane theory. The membrane theory may be the correct part, and the ionic theory does not give a definite affirmation; the membrane theory may be the wrong part, and ionic theory does not give a clear negative, instead, has been further strengthened in the later period. Whether it is membrane theory or ionic theory, the author has ignored the structure and characteristics of ion channels, and has not found the essence and law of ion exchange inside and outside the cell membrane. Therefore, the GHK equation and the H-H equation based on the ionic theory have congenital deficiencies. Therefore, it is necessary to put forward a new doctrine on this basis and establish a new mathematical model based on the new doctrine to re-explain the mechanism of bioelectricity generation scientifically and rationally. This paper is based on the principle of K+ channel “origami windmill” model, the conservation law of membrane area of cell action potential ion exchange was proposed, and establishes a new mathematical model of cell action potential based on the conservation law of membrane area—ion inequality equation. The expression of conservation law of membrane area: SA (t) + SB (t) = S0, the expression of the ion inequality equation: resting potential N = N0 + Vt; action potential N = N0+ 170t -90t2. The conservation law of membrane area holds that bioelectrical activity is a process in which different cations replace each other on the inner surface of the cell membrane. Cl- is already surrounded by the cell membrane at the beginning of cell membrane formation, which determines the “positive” and “negative” of the cell action potential; The cations such as Na+, K+, etc., the amount of mutual replacement on the inner surface of the cell membrane determines the amplitude of the action potential, and the ratio of mutual replacement complies with the principle that the membrane area is equal and the ions are not equal. The ion inequality equation, cited the kinematics principle, can not only reflect the nature and rule of cation exchange on the inner surface of cell membrane,but also can reasonable avoid cell membrane expansion force and ionic driving force, completed the bioelectricity generation mechanism from the qualitative to the quantitative expression, supports the preexistence of membrane theory, to verify the theory of brain cell activation, the theory of dove-likeparticles and “origami windmill” model, has opened up a scientific and quantitative description cell action potential new ways and means.

Sem-Images Indicate that Water Clusters or Ice-Crystals Are the Cause of Phyllotaxis

Authors: Harry K. Hahn
Comments: 37 pages, 110 figures, 10 tables

With my study I want to advance the hypothesis that a lattice ( network ) of Ice-Crystals or large Water Clusters together with special proteins, socalled Ice-binding proteins, is causing Phyllotaxis in plants. SEM-Images seem to proof this hypothesis. The (E)SEM-Image of the remains of an evaporated water droplet clearly shows a complex phyllotactic pattern ! This phyllotactic pattern formed during the evaporation of the water in the vacuum chamber of the SEM. The shown (E)SEM-Image is a first proof that Water must be the fundamental source of Phyllotaxis ! --> (E)SEM = (Environmental) Scanning Electron Microscope Responsible for the formation of the phyllotactic pattern seems to be a large central Water Cluster, that may have an icosahedral MacKay-geometry, consisting of large icosahedral Sub-Clusters formed by the stable icosahedral water clusters (H2O)100 or (H2O)280. Typical cluster numbers of Mackay-Clusters are 13 and 55 which are Fibonacci Numbers ! Additional evidence comes from SEM-Images of the generative zone of the Sunflower Capitulum. These images indicate that new primordia in the generative zone are caused by rhombic crystals, which seem to be either ice-crystals or large water cluster crystals that formed with the help of ice-binding proteins or water-cluster binding proteins. Additional proof for a physical cause of Phyllotaxis is provided by a study about variations in the Fibonacci-spiral patterns of twigs of the three “Pinus Mugo“ which shows that the Fibonacci-pattern variation depends from the altitude ( temperature / radiation conditions ) where the three grows. With the results of this study I developed an infinite Fibonacci-Number-Sequences-Table that contains all existing Fibonacci-Sequences and all natural numbers. Finally I present a mathematical discovery regarding constant Phi. All natural numbers and their square roots, as well as constant Pi (π), can be expressed by only using constant Phi (1.618…) and the base unit 1.

Nanoparticles Measure Cancer Cells

Authors: George Rajna
Comments: 77 Pages.

A first-of-its-kind nanoparticle-based in vivo imaging technique that may one day be used to help diagnose and even treat cancer has been developed by researchers collaborating from Michigan State, Johns Hopkins and Stanford universities. [50] The hope is that further research into cilia will help untangle the complex relationship between them and cancer, and provide both new insights into some of the drivers of cancer as well as new targets for cancer treatment. [49] Researchers have found that changing the mechanical properties of individual cells disrupts their ability to remain stable, profoundly affecting their health and the health of the tissue that comprises them. [48] Biochemists at the University of Bayreuth and the University of Bonn have now discovered a way to regulate this process which is central to gene expression: Certain actinobacteria contain a protein that binds RNA molecules under blue light and can thereby deactivate them. [47] A new piece of a difficult puzzle-the nature of memory-fell into place this week with a hint at how brain cells change structure when they learn something. [46] Researchers at the University of Alberta have found an important protein in the cells of a deadly infectious parasite, opening the door to less harmful treatment for millions of people suffering from diseases like sleeping sickness in Africa and Chagas disease in South America. [45] The remarkable ability of a small Australian sea snail to produce a colourful purple compound to protect its eggs is proving even more remarkable for its potential in a new anti-cancer pharmaceutical. [44] Gene editing technology is a technology that eliminates the underlying causes of and treats diseases by removing specific genesor editing genes to restore their normal function. In particular, CRISPR gene editing technology is now commonly used for immunotherapy by correcting the genes of immune cells to induce them to attack cancer cells selectively. [43]

[45] Researchers in Brazil analyzed the growth of confirmed infected COVID-19 cases across four continents to better characterize the spread of the virus and examine which strategies are effective in reducing its spread. [44] A system that checks from a safe distance whether someone is displaying symptoms of COVID-19 has been developed by Urs Schneider and colleagues at the Fraunhofer Institute for Manufacturing Engineering and Automation in Stuttgart, Germany. [43] Although the test still needs to be tested on intact viral RNA from patient samples, it could help relieve the current pressure on PCR-based tests, the researchers say. [42] Simon Fraser University researchers will use their pioneering imaging technology-called Mango, for its bright colour-to develop coronavirus testing kits. [41] According to the Centers for Disease Control and Prevention, common human coronaviruses usually cause mild to moderate upper-respiratory tract illnesses, like the common cold. [40] When diseases reinforce each other, they rapidly accelerate through the population, then fizzle out as they run out of new hosts. [39] It's no coincidence that some of the worst viral disease outbreaks in recent years-SARS, MERS, Ebola, Marburg and likely the newly arrived 2019-nCoV virus-originated in bats. [38] An interdisciplinary team of researchers at Colorado State University has used computational chemistry, biochemistry and virology to uncover new information on how viruses such as West Nile, dengue and Zika replicate.

Electromagnetic and Ultrasound Waves Exchange Between Dnas Within Cells, Rnas Within Coronaviruses and Towers in 5G Technology

Authors: Massimo Fioranelli, Alireza Sepehri, Maria Grazia Roccia, Aroonkumar Beesham
Comments: 26 pages, 5 figures

A DNA is built from charged electrons and atoms and has the inductor-like structure. This structure could be divided into linear, toroid and round inductors. These inductors interact with external electromagnetic waves, move and produce some extra waves within the cells. The shapes of these waves are similar to shapes of hexagonal and pentagonal bases of their DNA source. These electromagnetic waves interact with charged particles on the nuclear membranes and lead to their vibrations. By these vibrations, nuclear membranes act like vibrators within a speaker/microphone and some new ultrasound waves are emerged. Thus, DNAs within cells emit both electromagnetic and ultrasound waves. These waves produce some holes in liquids within the nucleus and cells. To fill these holes, some extra hexagonal and pentagonal bases are produced. These bases could join to each other and form some viruses like Coronavirus. To produce these viruses within a cell, its need that wavelength of external waves be shorter than the size of a cell. Thus 5G millimeter waves could be good candidates for applying in constructing Coronaviruses (COVID-19) within biological cells.

The insides of living cells can be seen in their natural state in greater detail than ever before using a new technique developed by researchers in Japan. [47] Scientists have been using fluorescence microscopy to study the inner workings of biological cells and organisms for decades.

Non-Linear Hexagonal/pentagonal Ultrasound Waves Exchange Between Covid-19 and Dermatologic Antenna

Authors: Alireza Sepehri, Massimo Fioranelli, Maria Grazia Roccia, Aroonkumar Beesham
Comments: 25 pages, 12 figures

In this research, we propose an antenna model for cells and determine the shape and the wavelength of DNA ultrasound waves which are emited or received by dermatologic antenna. In this model, we show that the structure of a DNA within a nucleus is very similar to an inductor within a speaker/microphone and produce some ultrasound waves. We divide the structure of a DNA into several linear and curved inductors. Linear inductors emit linear magnetic fields and curved inductors produce curved waves. Also, DNA inductors are built from hexagonal and pentagonal bases and consequently emit hexagonal and pentagonal waves. On the other hand, nuclear membranes play the role of magnets within a speaker/microphone. Charged particles out and within nucleus, produce some electric fields along nuclear membranes. These fields produce some currents along membranes. These currents emit some magnetic fields which interact with DNA inductors. The interactions between magnetic fields of membrane and DNA inductors lead to their motions. By motions of charged particles within DNA inductors, some currents are emerged. These currents emit some extra magnetic fields. These magnetic fields interact with nuclear membranes and vibrate them. In these conditions, membranes play the role of plastic within a speaker/microphone. By vibrating nuclear membranes, some linear/curved hexagonal/pentagonal ultrasound waves are emerged. Frequency of these waves are more than frequency of light waves and their wavelengths are smaller than size of air molecules. Thus, these waves pass air molecules and propagate in any empty vacuum. These waves could be taken by viral RNAs in COVID-19 and move them. These RNAs act like the round inductors, vibrate and lead to the vibrations of viral membranes. By vibrations of RNA membranes, some new waves are emerged that are taken by dermatologic antennas. Exchanging waves between Covid-19 and dermatologic antennas causes to absrorptions of viruses by biological human’s body. Wavelenths of Coronaviruses are in the range of wavelengths in 5G technology. Thus, using waves in this technology, we can control COVID-19. On the other hand, millimeter waves in 5G technology could be absorbed by the cell membranes. These waves move molecules within cells and produce some stronger waves. These new waves pass the nuclear membranes, move DNAs and produce some hexagonal/pentagonal holes. To fill these holes, some bases are emerged. These bases join to each other and form some viral RNAs like RNAs of Coronaviruses. Thus, millimeter waves in 5G technology could play the role in constructing Coronaviruses within cells.

Genes Affecting Life Span

Authors: George Rajna
Comments: 74 Pages.

Scientists believe about 25 percent of the differences in human life span is determined by genetics-with the rest determined by environmental and lifestyle factors. But they don't yet know all the genes that contribute to a long life. [44] Researchers in Japan have discovered that the DNA inside human cells moves around less when its genes are active. [43] Matthias Wilmanns and colleagues at the European Molecular Biology Laboratory in Hamburg, Germany, developed methods to study the structure of a protein "strain absorber" as it changes during muscle contractions. [42] Using pulsed infrared light lasers, scientists have activated molecules located inside neural tissue with an efficiency of almost 100 percent. [41] DNA damage is occurring in our cells all the time due to external agents, such as exposure to sun, or internal agents, like reactive oxygen species. To detect and repair DNA lesions, cells have evolved DNA damage response. [40] When Greg Bowman presents a slideshow about the proteins he studies, their 3-D shapes and folding patterns play out as animations on a big screen.

Quantitative biologists David McCandlish and Juannan Zhou at Cold Spring Harbor Laboratory have developed an algorithm with predictive power, giving scientists the ability to see how specific genetic mutations can combine to make critical proteins change over the course of a species's evolution. [34] Reconstructing evolutionary branches is tricky, especially when many species share a similar type of protein that might have evolved to perform somewhat different functions.

Scientists have been using fluorescence microscopy to study the inner workings of biological cells and organisms for decades.

Treatment of COVID-19 by Improving Blood Supply in Lung

Authors: Bing Luo
Comments: 5 Pages.

In blood circulation (systemic circulation), the order of blood circulation is that arterial blood flows into capillaries only after venous blood refluxes. The human body controls the flow of arterial blood into capillaries by controlling the flow of venous blood. The refluxing power of venous blood changes with the rotation and revolution of the earth, and leads to changes in arterial blood obtained by cells, tissues and organs. If the refluxing power of venous blood of the lungs has a problem, the actual amount of blood obtained by the lungs will be less than the amount of blood distributed to the lungs by the human body (supplying the lungs with nutrients and oxygen they need), and what Pasteur called “the terrain” (There is a paragraph in Seasons of Life: “On his deathbed, Louis Pasteur, the founder of the germ theory of disease, allegedly said, ‘the germ is nothing, the terrain is everything’.”) will form in the lungs.

[24] Now, researchers at Stevens Institute of Technology and colleagues have modeled how these toxic proteins spread throughout the brain to reproduce the telltale patterns of atrophy associated with Alzheimer's disease, Parkinson's disease, and amyotrophic lateral sclerosis, or ALS.

A tiny chemical modification on one of the most abundant and important proteins in cells, actin, has long been somewhat mysterious, its function not fully understood, but scientists from the Perelman School of Medicine at the University of Pennsylvania have now taken a big step towards clearing up the mystery. [27] It's a remarkable choreography. In each of our bodies, more than 37 trillion cells tightly coordinate with other cells to organize into the numerous tissues and organs that make us tick.

The Nature of the Origin of the Coronavirus Revealed Measures to Stop the Pandemic

Authors: V.Korniienko, V.Belocrinicky, I.Vikulin
Comments: 37 Pages. In English and Russian

The cause of the natural hotbeds of the coronavirus pandemic is ambiguous, which causes its rapid development. This reason reveals a technique that shows that matter has a quantum electromagnetic field (QEF) that provides stability to the properties of any matter. It is shown that despite the absence of Sun activity, it generates waves of quantum electromagnetic energies (S-radiations). They contain information whose effect on the QEF of human matter causes the development of coronavirus in his body and the emergence of natural centers of pandemic. Measures have been proposed, the implementation of which will exclude the possibility of the emergence of natural centers of coronavirus and will revive the economy.

In a new study published in Nature Communications, a research team from Virginia Tech reported that they had found a substantial collection of genes for metabolic cycles-a defining characteristic of cellular life-in a wide range of "giant viruses." [10] A research team led by physicist Roya Zandi at the University of California, Riverside, has made progress is solving this mystery. [9] A protein involved in cognition and storing long-term memories looks and acts like a protein from viruses. [8] Discovery of quantum vibrations in 'microtubules' inside brain neurons supports controversial theory of consciousness The human body is a constant flux of thousands of chemical/biological interactions and processes connecting molecules, cells, organs, and fluids, throughout the brain, body, and nervous system. Up until recently it was thought that all these interactions operated in a linear sequence, passing on information much like a runner passing the baton to the next runner. However, the latest findings in quantum biology and biophysics have discovered that there is in fact a tremendous degree of coherence within all living systems. The accelerating electrons explain not only the Maxwell Equations and the Special Relativity, but the Heisenberg Uncertainty Relation, the Wave-Particle Duality and the electron's spin also, building the Bridge between the Classical and Quantum Theories. The Planck Distribution Law of the electromagnetic oscillators explains the electron/proton mass rate and the Weak and Strong Interactions by the diffraction patterns. The Weak Interaction changes the diffraction patterns by moving the electric charge from one side to the other side of the diffraction pattern, which violates the CP and Time reversal symmetry. The diffraction patterns and the locality of the self-maintaining electromagnetic potential explains also the Quantum Entanglement, giving it as a natural part of the Relativistic Quantum Theory and making possible to understand the Quantum Biology.

Self-Replication of the J. Byl Replicator in Cellular Automata Space With Permutations of the State Set.

Authors: Perry W Swanborough
Comments: 6 Pages.

It has been established that heterochiral self-replication of loop structures in cellular automata (CA) spaces cannot be achieved by pooling a state-transition function with its corresponding mirror transition function because some chiral rules specific to right-handed replication are contradicted by chiral rules specific for left-handed replication. A less-strict functional heterochirality of self-reproduction by structures in CA space, notionally achievable by permutation-transformation of structures and transition functions, was hypothesized. Over all possible state-set permutations, it was found that there is no permutation-transformation of the left-handed form of the J. Byl (1989) state-transition function which corresponds to no contradictions with the right-handed (original) transition function. This result demonstrates that the structure’s replication is robustly homochiral.

[9] A protein involved in cognition and storing long-term memories looks and acts like a protein from viruses. [8] Discovery of quantum vibrations in 'microtubules' inside brain neurons supports controversial theory of consciousness The human body is a constant flux of thousands of chemical/biological interactions and processes connecting molecules, cells, organs, and fluids, throughout the brain, body, and nervous system. Up until recently it was thought that all these interactions operated in a linear sequence, passing on information much like a runner passing the baton to the next runner. However, the latest findings in quantum biology and biophysics have discovered that there is in fact a tremendous degree of coherence within all living systems. The accelerating electrons explain not only the Maxwell Equations and the Special Relativity, but the Heisenberg Uncertainty Relation, the Wave-Particle Duality and the electron's spin also, building the Bridge between the Classical and Quantum Theories. The Planck Distribution Law of the electromagnetic oscillators explains the electron/proton mass rate and the Weak and Strong Interactions by the diffraction patterns. The Weak Interaction changes the diffraction patterns by moving the electric charge from one side to the other side of the diffraction pattern, which violates the CP and Time reversal symmetry. The diffraction patterns and the locality of the self-maintaining electromagnetic potential explains also the Quantum Entanglement, giving it as a natural part of the Relativistic Quantum Theory and making possible to understand the Quantum Biology.

Are Qualia Reducible, Physical Entities?

Authors: Christian Kerskens
Comments: 5 Pages.

Controversial hypotheses to explain consciousness exist in many fields of science, psychology and philosophy. Recent experimental findings in quantum cognition and magnetic resonance imaging have added new controversies to the field, suggesting that the mind may be based on quantum computing. Quantum computers process information in quantum bits (qubits) using quantum gates. At a first glance, it seems unrealistic or impossible that the brain can meet the challenges to provide either of these. Nevertheless, we show here why the brain has the incredible ability to perform quantum computing and how that may be realized.

EPFL researchers have developed a device that can zoom in on previously invisible cells at the back of the eye. The technology could be extremely useful for ophthalmologists, in particular for detecting age-related macular degeneration early and assessing new treatment options. [33] A research team led by the University of California San Diego has developed a soft robotic lens whose movements are controlled by the eyes—blink twice and the lens zooms in and out; look left, right, up or down and the lens will follow.

Particle Therapy Dose Distribution

Authors: George Rajna
Comments: 53 Pages.

Precise patient positioning is an essential stage in any radiation treatment, but is particularly critical for particle therapies, which are highly sensitive to range uncertainties. [33] Ion beam radiotherapy offers precision dose deposition, with a low entrance dose increasing to a maximum at the Bragg peak and then falling off sharply. [32] Researchers at Aalto University have discovered a surprising phenomenon that changes how we think about how sound can move particles. [31] Large-scale plasmonic metasurfaces could find use in flat panel displays and other devices that can change colour thanks to recent work by researchers at the University of Cambridge in the UK. [30] Particles in solution can grow, transport, collide, interact, and aggregate into complex shapes and structures. [29] Lawrence Livermore National Laboratory (LLNL) researchers are working to make better electronic devices by delving into the way nanocrystals are arranged inside of them. [28] Self-assembly and crystallisation of nanoparticles (NPs) is generally a complex process, based on the evaporation or precipitation of NP-building blocks. [27] New nanoparticle-based films that are more than 80 times thinner than a human hair may help to fill this need by providing materials that can holographically archive more than 1000 times more data than a DVD in a 10-by-10-centimeter piece of film. [26] Researches of scientists from South Ural State University are implemented within this area. [25] Following three years of extensive research, Hebrew University of Jerusalem (HU) physicist Dr. Uriel Levy and his team have created technology that will enable computers and all optic communication devices to run 100 times faster through terahertz microchips. [24] When the energy efficiency of electronics poses a challenge, magnetic materials may have a solution. [23]

A cheap, biocompatible white powder that luminesces when heated could be used for non-invasively monitoring the temperature of specific organs within the body. [37] The Internet of Things (IoT) is a technology classification that includes home appliances and other items embedded with electronics, software, sensors, and actuators that connect and exchange data. One key IoT technology is optical fiber sensing.

Graphite Nanoplatelets Kill Bacteria

Authors: George Rajna
Comments: 72 Pages.

Graphite nanoplatelets integrated into plastic medical surfaces can prevent infections, killing 99.99 per cent of bacteria which try to attach—a cheap and viable potential solution to a problem which affects millions, costs huge amounts of time and money, and accelerates antibiotic resistance. [43] Researchers at The University of Manchester in the UK, led by Dr. Artem Mishchenko, Prof Volodya Fal'ko and Prof Andre Geim, have discovered the quantum Hall effect in bulk graphite—a layered crystal consisting of stacked graphene layers. [42] Light particles normally do not "feel" each other because there is no interaction acting between them. Researchers at ETH have now succeeded in manipulating photons inside a semiconductor material in such a way as to make them repel each other nevertheless. [41]

Antibodies are proteins that act as recognition molecules for pathogens, like viruses and bacteria, and are the workhorses of the body's immune system. [27] According to the World Health Organization, one of the biggest health threats around the world is antibiotic-resistant bacteria. [26] Researchers at the University of Illinois at Chicago have identified a molecular switch that causes immune cells called macrophages to clean up cellular debris caused by infections instead of contributing to inflammation and tissue injury.

Graphene-based biosensors could usher in an era of liquid biopsy, detecting DNA cancer markers circulating in a patient's blood or serum. [37] What we learned in this study is extremely useful in designing new drugs because it tells us which areas to target to block the checkpoint protein's function." [36] Now, in a watershed advance, engineers at the University of California, Riverside, in collaboration with researchers at City of Hope National Medical Center, have invented a device that holds potential for mass-producing engineered cells at lower cost, a tipping point for these lifesaving therapies.

Bacteria Carry Microscopic Cargo

Authors: George Rajna
Comments: 27 Pages.

In a paper published in Nature Physics, researchers at the Niels Bohr Institute, University of Copenhagen, in collaboration with groups in U.S. and U.K., have now reported doing just that. They have found a way to control bacteria to transport microscopic cargo. [16] Biochemists at the University of Illinois have isolated a protein supercomplex from a bacterial membrane that, like a battery, generates a voltage across the bacterial membrane. [15] Scientists from Moscow State University (MSU) working with an international team of researchers have identified the structure of one of the key regions of telomerase-a so-called "cellular immortality" ribonucleoprotein. [14] Researchers from Tokyo Metropolitan University used a light-sensitive iridium-palladium catalyst to make "sequential" polymers, using visible light to change how building blocks are combined into polymer chains. [13] Researchers have fused living and non-living cells for the first time in a way that allows them to work together, paving the way for new applications. [12] UZH researchers have discovered a previously unknown way in which proteins interact with one another and cells organize themselves. [11] Dr Martin Sweatman from the University of Edinburgh's School of Engineering has discovered a simple physical principle that might explain how life started on Earth. [10] Nearly 75 years ago, Nobel Prize-winning physicist Erwin Schrödinger wondered if the mysterious world of quantum mechanics played a role in biology. A recent finding by Northwestern University's Prem Kumar adds further evidence that the answer might be yes. [9] A UNSW Australia-led team of researchers has discovered how algae that survive in very low levels of light are able to switch on and off a weird quantum phenomenon that occurs during photosynthesis. [8] This paper contains the review of quantum entanglement investigations in living systems, and in the quantum mechanically modeled photoactive prebiotic kernel systems. [7] The human body is a constant flux of thousands of chemical/biological interactions and processes connecting molecules, cells, organs, and fluids, throughout the brain, body, and nervous system. Up until recently it was thought that all these interactions operated in a linear sequence, passing on information much like a runner passing the baton to the next runner. However, the latest findings in quantum biology and biophysics have discovered that there is in fact a tremendous degree of coherence within all living systems. The accelerating electrons explain not only the Maxwell Equations and the Special Relativity, but the Heisenberg Uncertainty Relation, the Wave-Particle Duality and the electron's spin also, building the Bridge between the Classical and Quantum Theories. The Planck Distribution Law of the electromagnetic oscillators explains the electron/proton mass rate and the Weak and Strong Interactions by the diffraction patterns. The Weak Interaction changes the diffraction patterns by moving the electric charge from one side to the other side of the diffraction pattern, which violates the CP and Time reversal symmetry. The diffraction patterns and the locality of the self-maintaining electromagnetic potential explains also the Quantum Entanglement, giving it as a natural part of the Relativistic Quantum Theory and making possible to understand the Quantum Biology.

Mayo Clinic have leveraged new ultrasound tracking technology to reveal the hypoxic status of tumours. [34] Using the latest advances in imaging and computing, Johns Hopkins Medicine researchers have developed a framework that's able to reveal the structural and functional changes in the blood vessel network required for growth of a tumour. [33] Medical physicist Dr. Aswin Hoffmann and his team from the Institute of Radiooncology-OncoRay at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have combined magnetic resonance imaging (MRI) with a proton beam, thus demonstrating for the first time that in principle, this commonly used imaging method can work with particle beam cancer treatments. [32] Washington State University researchers for the first time have shown that they can use electrical fields to gain valuable information about the tiny, floating vesicles that move around in animals and plants and are critically important to many biological functions. [31] Finding a fast and inexpensive way to detect specific strains of bacteria and viruses is critical to food safety, water quality, environmental protection and human health. [30] In the perspective, Gabor and Song collect early examples in electron metamaterials and distil emerging design strategies for electronic control from them. [29] Lawrence Livermore National Laboratory (LLNL) researchers are working to make better electronic devices by delving into the way nanocrystals are arranged inside of them.

University researchers will use their pioneering imaging technology-called Mango, for its bright colour-to develop coronavirus testing kits. [41] According to the Centers for Disease Control and Prevention, common human coronaviruses usually cause mild to moderate upper-respiratory tract illnesses, like the common cold. [40] When diseases reinforce each other, they rapidly accelerate through the population, then fizzle out as they run out of new hosts. [39] It's no coincidence that some of the worst viral disease outbreaks in recent years-SARS, MERS, Ebola, Marburg and likely the newly arrived 2019-nCoV virus-originated in bats. [38] An interdisciplinary team of researchers at Colorado State University has used computational chemistry, biochemistry and virology to uncover new information on how viruses such as West Nile, dengue and Zika replicate. [37] David Baker, Professor of Biochemistry and Director of the Institute for Protein Design at the University of Washington will speak about how algorithmic processes such as de novo design predict protein structures, protein folding mechanisms, and new protein functions. [36] A research team at Kobe University has developed a method of artificially controlling the anchorage position of target proteins in engineered baker's yeast (Saccharomyces cerevisiae).

Chemists at Texas A&M University are taking a p[h]age from bacteria's playbook in order to beat viruses at their own game and develop new drugs to fight cancer and a host of other human diseases in the process. [27] Researchers at Western University have developed a new way to deliver the DNA-editing tool CRISPR-Cas9 into microorganisms in the lab, providing a way to efficiently launch a targeted attack on specific bacteria. [26] The work reflects a growing trend at both the Salk Institute and elsewhere toward integrating computational approaches into biology research. [25] That's only a smattering of what scientists will be able to examine with the new microscope-an atomic force-Raman microscope, to be exact-now housed in the University of Delaware's Lammot du Pont Laboratory. [24] The Pt nanoreactor was designed with a controlled core-shell structure and morphology for the visual detection of metabolic biomarkers and direct laser desorption/ionization MS fingerprinting of the native serum. [23] Nuclear technology companies Phoenix and SHINE Medical Technologies have achieved a new world record for a nuclear fusion reaction in a steady-state system, the strongest of its kind ever produced on Earth. [22] Bacterial systems are some of the simplest and most effective platforms for the expression of recombinant proteins. [21] Now, in a new paper published in Nature Structural & Molecular Biology, Mayo researchers have determined how one DNA repair protein gets to the site of DNA damage.

Nanoimaging Aid Drug Development

Authors: George Rajna
Comments: 42 Pages.

Chemotherapeutics are key players in the clinical setting to fight most types of cancer, and novel chemicals could facilitate new and unique intracellular interactions that modulate the cell machinery and destroy the tumor cells. [32] Researchers at The University of Texas at Austin have developed new guidelines for fabricating nanoscale gel materials, or nanogels, that can deliver numerous therapeutic treatments to treat cancer in a precise manner. In addition to enabling the delivery of drugs in response to tumors, their nanogels can target malignant cells (or biomarkers), degrade into nontoxic components and execute multiple clinical functions. [31] A revolutionary, cutting-edge technology, developed by researchers at Bar-Ilan University's Institute of Nanotechnology and Advanced Materials (BINA), has the potential to provide a new alternative to eyeglasses, contact lenses, and laser correction for refractive errors. [30] Electrons in graphene-an atomically thin, flexible and incredibly strong substance that has captured the imagination of materials scientists and physicists alike-move at the speed of light, and behave like they have no mass. [29] In a series of exciting experiments, Cambridge researchers experienced weightlessness testing graphene's application in space. [28] Scientists from ITMO University have developed effective nanoscale light sources based on halide perovskite.

[24] In a joint research project, scientists from the Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI), the Technische Universität Berlin (TU) and the University of Rostock have managed for the first time to image free nanoparticles in a laboratory experiment using a highintensity laser source. [23] For the first time, researchers have built a nanolaser that uses only a single molecular layer, placed on a thin silicon beam, which operates at room temperature. [22]

A novel hybrid microscope delivers the same information as standard optical microscopy without the need for detrimental tissue staining, while also providing molecular insight into tissue biopsies [38] A new system capable of probing microscopic environments inside cells has been installed at the University of Exeter's Bioimaging Centre. [37] "We put the optical microscope under a microscope to achieve accuracy near the atomic scale," said NIST's Samuel Stavis, who served as the project leader for these efforts. [36] Researchers have designed an interferometer that works with magnetic quasiparticles called magnons, rather than photons as in conventional interferometers. [35] A technique to manipulate electrons with light could bring quantum computing up to room temperature. [34] The USTC Microcavity Research Group in the Key Laboratory of Quantum Information has perfected a 4-port, all-optically controlled non-reciprocal multifunctional photonic device based on a magnetic-field-free optomechanical resonator. [33] To address this technology gap, a team of engineers from the National University of Singapore (NUS) has developed an innovative microchip, named BATLESS, that can continue to operate even when the battery runs out of energy. [32] Stanford researchers have developed a water-based battery that could provide a cheap way to store wind or solar energy generated when the sun is shining and wind is blowing so it can be fed back into the electric grid and be redistributed when demand is high. [31] Researchers at AMOLF and the University of Texas have circumvented this problem with a vibrating glass ring that interacts with light. They thus created a microscale circulator that directionally routes light on an optical chip without using magnets.

Rutgers researchers have discovered the origins of the protein structures responsible for metabolism: simple molecules that powered early life on Earth and serve as chemical signals that NASA could use to search for life on other planets. [38] Researchers in Dana-Farber's cBio Center have now demonstrated a powerful 'experimental evolution' method to discover details of protein shape and function, and the method may find uses across a very broad spectrum of biomedical research. [37] The discovery, published in Nature Communications, could help uncover treatments for age-related conditions, such as Alzheimer's disease, which are often caused by accumulation of misfolded proteins. [36] Korean researchers have used light to control the binding of two separate and inactive antibody fragments and generate a specific, timely immune response to antigens. [35] A new Empa study recently published in Nature Communications shows how this amazing behavior can be improved-and even used to treat injuries and tissue damage. [34] Scientists at Johns Hopkins Medicine report they have created a tiny, nanosize container that can slip inside cells and deliver protein-based medicines and gene therapies of any size-even hefty ones attached to the gene-editing tool called CRISPR. [33] Protocells-artificial cells-that are active and mimic living cells by moving independently and that are biocompatible and enzymatically active are now possible using an improved method developed by Penn State researchers. [32] Pioneering new research into the way in which cells communicate with each other could hold the key to unlocking new, improved treatment for life-threatening diseases, including cancer. [31] Researchers at the University of Illinois at Chicago have demonstrated that magnetic nanoparticles can be used to ferry chemotherapy drugs into the spinal cord to treat hard-to-reach spinal tumors in an animal model.

We argue that the new coronavirus COVID-19 was probably linked to the arrival of a pure culture of the virus in cometary debris that was deposited in the stratosphere, and first came down in the Wuhan province of China. The subsequent worldwide spread of the virus has taken place by a combination of two effects: the deposition of further large quantities of virus at several locations – Iran, North Italy, South Korea – combined with much slower spread through person-to-person infection (itself largely by contaminated surfaces and personal affects). The location of the foci outside China all lie close to latitude 40 degrees N, consistent with the transport of aerosols by cyclonic winds in the stratosphere. It is also remarkably consistent with observations in the 1960’s of the fall-out of radioactive dust deposited in the stratosphere in the last of the atmospheric atom bomb tests. On this basis, we conclude that a stratospheric loading of the Coronavirus that happened in October/November 2019 could take a few winter seasons to be fully drained. A clearer understanding of the causal events that led to the COVID-19 pandemic could help planning future strategy.

Low-Dose CT Doesn’t Damage DNA

Authors: George Rajna
Comments: 39 Pages.

To investigate whether exposure to low-dose CT could increase the risk of radiation-induced cancers, a Japanese research team compared the number of DNA double-strand breaks and chromosome aberrations in peripheral blood lymphocytes following low-dose and standard-dose chest CT. [23] Biology encodes information in DNA and RNA, which are complex molecules finely tuned to their functions. [22] When cells suffer DNA damage, they send out an SOS signal. When the repair crew arrives, the emergency signal is cancelled as it is no longer needed. [21]

Virus Forms its Symmetric Shells

A research team led by physicist Roya Zandi at the University of California, Riverside, has made progress is solving this mystery. [9] A protein involved in cognition and storing long-term memories looks and acts like a protein from viruses. [8] Discovery of quantum vibrations in 'microtubules' inside brain neurons supports controversial theory of consciousness The human body is a constant flux of thousands of chemical/biological interactions and processes connecting molecules, cells, organs, and fluids, throughout the brain, body, and nervous system. Up until recently it was thought that all these interactions operated in a linear sequence, passing on information much like a runner passing the baton to the next runner. However, the latest findings in quantum biology and biophysics have discovered that there is in fact a tremendous degree of coherence within all living systems. The accelerating electrons explain not only the Maxwell Equations and the Special Relativity, but the Heisenberg Uncertainty Relation, the Wave-Particle Duality and the electron's spin also, building the Bridge between the Classical and Quantum Theories. The Planck Distribution Law of the electromagnetic oscillators explains the electron/proton mass rate and the Weak and Strong Interactions by the diffraction patterns. The Weak Interaction changes the diffraction patterns by moving the electric charge from one side to the other side of the diffraction pattern, which violates the CP and Time reversal symmetry. The diffraction patterns and the locality of the self-maintaining electromagnetic potential explains also the Quantum Entanglement, giving it as a natural part of the Relativistic Quantum Theory and making possible to understand the Quantum Biology.

Wang, Bren Professor of Medical Engineering and Electrical Engineering, has now further advanced photoacoustic imaging technology with what he calls Photoacoustic Topography Through an Ergodic Relay (PATER), which aims to simplify the equipment required for imaging of this type. [16] Researchers supported by the EU-funded photonics innovation incubator ACTPHAST 4.0 have introduced "a swept light source technology that makes it possible to take full 3-D OCT [optical coherence tomography] images of the eye," says a news release posted on the project website.

Comments on the Origin and Spread of the 2019 Coronavirus

Authors: N Chandra Wickramasinghe, Edward J Steele, Reginald M Gorczynski, Robert Temple, Gensuke Tokoro, Jiangwen Qu, Daryl H Wallis, Brig Klyce
Comments: 4 Pages.

We propose that the new coronavirus which first appeared in the Hubei province of China was probably linked to the arrival of a pure culture of the virus contained in cometary debris that was dispersed over a localised area of the planet namely China. The sighting of a fireball some 2000 kilometers north of Wuhan on 11 October 2019 followed shortly after with the first recorded cases in Hubei is suggestive of a causal link. Gene sequencing data of the virus that show little or no genetic variations between isolates, combined with available epidemiological data point to the predominance of a transmission process directly from an “infected” environment, with person- to-person transmission playing a comparatively weaker secondary role. The facts relating to this epidemic are discussed and placed in the context of other pandemics that have been recorded throughout history.

Comments: 70 Pages.

EPFL scientists have developed a new type of microscope slide that can boost the amount of light in fluorescence microscopy by a factor of up to 25. [46] Selecting the most effective molecules for drug delivery is often a trial-and-error process, but Cornell engineers are providing some precision thanks to a technique that reveals the performance of those molecules inside living cells. [45] Now, researchers at MIT and elsewhere have developed a system to deliver medical treatments that can be released at precise times, minimally-invasively, and that ultimately could also deliver those drugs to specifically targeted areas such as a specific group of neurons in the brain. [44] Gene editing technology is a technology that eliminates the underlying causes of and treats diseases by removing specific genesor editing genes to restore their normal function. In particular, CRISPR gene editing technology is now commonly used for immunotherapy by correcting the genes of immune cells to induce them to attack cancer cells selectively. [43]

Technologies like this could contribute significantly to the fight against antimicrobial resistance. [20] For bacteria facing a dose of antibiotics, timing might be the key to evading destruction. In a series of experiments, Princeton researchers found that cells that repaired DNA damaged by antibiotics before resuming growth had a much better chance of surviving treatment. [19] It's called gene editing, and University of Alberta researchers have just published a game-changing study that promises to bring the technology much closer to therapeutic reality. [18]

Coronavirus is Not Alone

When diseases reinforce each other, they rapidly accelerate through the population, then fizzle out as they run out of new hosts. [39] It's no coincidence that some of the worst viral disease outbreaks in recent years-SARS, MERS, Ebola, Marburg and likely the newly arrived 2019-nCoV virus-originated in bats. [38] An interdisciplinary team of researchers at Colorado State University has used computational chemistry, biochemistry and virology to uncover new information on how viruses such as West Nile, dengue and Zika replicate. [37] David Baker, Professor of Biochemistry and Director of the Institute for Protein Design at the University of Washington will speak about how algorithmic processes such as de novo design predict protein structures, protein folding mechanisms, and new protein functions. [36] A research team at Kobe University has developed a method of artificially controlling the anchorage position of target proteins in engineered baker's yeast (Saccharomyces cerevisiae). [35] Scientists have found a new way to home in on the proteins covering a particular cell's surface. The feat offers insight into how brain cells form intricate networks during development. [34]

Neutrons for Dental Restorations

Authors: George Rajna
Comments: 24 Pages.

Neutron scattering research provides insights that may lead to the development of novel materials for implant dentistry, he said. [14] Coupled with SNS, the world's most powerful pulsed accelerator-based neutron source, VENUS will be the only open research facility platform in the US to provide time-of-flight neutron imaging capabilities to users from academia and industry. [13] A spallation neutron source has been used by physicists in Japan to search for possible violations of the inverse square law of gravity. [12] Physicists have proposed a way to test quantum gravity that, in principle, could be performed by a laser-based, table-top experiment using currently available technology. [11] Now however, a new type of materials, the so-called Weyl semimetals, similar to 3-D graphene, allow us to put the symmetry destructing quantum anomaly to work in everyday phenomena, such as the creation of electric current. [10] Physicist Professor Chunnong Zhao and his recent PhD students Haixing Miao and Yiqiu Ma are members of an international team that has created a particularly exciting new design for gravitational wave detectors. [9] A proposal for a gravitational-wave detector made of two space-based atomic clocks has been unveiled by physicists in the US. [8] The gravitational waves were detected by both of the twin Laser Interferometer Gravitational-Wave Observatory (LIGO) detectors, located in Livingston, Louisiana, and Hanford, Washington, USA. [7] A team of researchers with the University of Lisbon has created simulations that indicate that the gravitational waves detected by researchers with the LIGO project, and which are believed to have come about due to two black holes colliding, could just have easily come from another object such as a gravaster (objects which are believed to have their insides made of dark energy) or even a wormhole. In their paper published in Physical Review Letters, the team describes the simulations they created, what was seen and what they are hoping to find in the future. [6] In a landmark discovery for physics and astronomy, international scientists said Thursday they have glimpsed the first direct evidence of gravitational waves, or ripples in space-time, which Albert Einstein predicted a century ago. [5] Scientists at the National Institute for Space Research in Brazil say an undiscovered type of matter could be found in neutron stars (illustration shown). Here matter is so dense that it could be 'squashed' into strange matter. This would create an entire 'strange star'-unlike anything we have seen. [4] The changing acceleration of the electrons explains the created negative electric field of the magnetic induction, the electromagnetic inertia, the changing relativistic mass and the Gravitational Force, giving a Unified Theory of the physical forces. Taking into account the Planck Distribution Law of the electromagnetic oscillators also, we can explain the electron/proton mass rate and the Weak and Strong Interactions.

A new article by the Oxidative Stress and Cell Cycle research group at UPF identifies the main strategy of cells to deal with the accumulation of misfolded proteins. [34] These will then produce the proteins themselves, without the cell functions being disturbed: cells, structures or their activities thus become visible under the microscope. [33] Measuring optical blood flow in the resting human brain to detect spontaneous activity has for the first time been demonstrated by Wright State University imaging researchers, holding out promise for a better way to study people with autism, Alzheimer's and depression.

Researchers can uncover how proteins interact with other proteins with far greater sensitivity and in a more natural context than conventional methods, thanks to an analytic technique developed by a RIKEN team. [22] Histones are proteins that regulate the unwinding of DNA in the cell nucleus and the expression of genes based on chemical modifications or "marks" that are placed on their tails. [21] Now, in a new paper published in Nature Structural & Molecular Biology, Mayo researchers have determined how one DNA repair protein gets to the site of DNA damage. [20] A microscopic thread of DNA evidence in a public genealogy database led California authorities to declare this spring they had caught the Golden State Killer, the rapist and murderer who had eluded authorities for decades. [19] Researchers at Delft University of Technology, in collaboration with colleagues at the Autonomous University of Madrid, have created an artificial DNA blueprint for the replication of DNA in a cell-like structure.

[15] Scientists from Moscow State University (MSU) working with an international team of researchers have identified the structure of one of the key regions of telomerase-a so-called "cellular immortality" ribonucleoprotein. [14] Researchers from Tokyo Metropolitan University used a light-sensitive iridium-palladium catalyst to make "sequential" polymers, using visible light to change how building blocks are combined into polymer chains. [13] Researchers have fused living and non-living cells for the first time in a way that allows them to work together, paving the way for new applications. [12]

[27] According to the World Health Organization, one of the biggest health threats around the world is antibiotic-resistant bacteria.

SR-FACT visualizes both the cellular landscape and the molecular identity of live cells. [38] Using a familiar tool in a way it was never intended to be used opens up a whole new method to explore materials, report UConn researchers in Proceedings of the National Academy of Science. [37] "We put the optical microscope under a microscope to achieve accuracy near the atomic scale," said NIST's Samuel Stavis, who served as the project leader for these efforts. [36] Researchers have designed an interferometer that works with magnetic quasiparticles called magnons, rather than photons as in conventional interferometers. [35] A technique to manipulate electrons with light could bring quantum computing up to room temperature. [34] The USTC Microcavity Research Group in the Key Laboratory of Quantum Information has perfected a 4-port, all-optically controlled non-reciprocal multifunctional photonic device based on a magnetic-field-free optomechanical resonator. [33] To address this technology gap, a team of engineers from the National University of Singapore (NUS) has developed an innovative microchip, named BATLESS, that can continue to operate even when the battery runs out of energy. [32] Stanford researchers have developed a water-based battery that could provide a cheap way to store wind or solar energy generated when the sun is shining and wind is blowing so it can be fed back into the electric grid and be redistributed when demand is high. [31] Researchers at AMOLF and the University of Texas have circumvented this problem with a vibrating glass ring that interacts with light. They thus created a microscale circulator that directionally routes light on an optical chip without using magnets. [30] Researchers have discovered three distinct variants of magnetic domain walls in the helimagnet iron germanium (FeGe). [29] Magnetic materials that form helical structures-coiled shapes comparable to a spiral staircase or the double helix strands of a DNA molecule-occasionally exhibit exotic behavior that could improve information processing in hard drives and other digital devices.

Supramolecular Linkages

Authors: George Rajna
Comments: 25 Pages.

Supramolecular Linkages NUS biophysicists have developed a manipulation assay that can quantify the mechanical stability and biochemical regulations of inter-molecular interactions at the single-molecule level. [19] Now, a team of researchers led by Dongsheng Li, a materials scientist at PNNL, and collaborators at the University of Michigan and the Chinese Academy of Sciences, have unlocked the secret to one of the most useful nanostructures: the five-fold twin. [18] The researchers have generated femtosecond laser pulses, with tailor-made, temporally varying polarizations, which are themselves chiral. [17] The scientists identified a shortlist, a kind of "periodic table" of the most designable knot types, i.e. those knots that could easily self-assemble under appropriate physical and chemical conditions. [16] Scientists have now observed for the first time how diamonds grow from seed at an atomic level, and discovered just how big the seeds need to be to kick the crystal growing process into overdrive. [15] The researchers engineered diamond strings that can be tuned to quiet a qubit's environment and improve memory from tens to several hundred nanoseconds, enough time to do many operations on a quantum chip. [14] Intel has announced the design and fabrication of a 49-qubit superconducting quantum-processor chip at the Consumer Electronics Show in Las Vegas. To improve our understanding of the so-called quantum properties of materials, scientists at the TU Delft investigated thin slices of SrIrO3, a material that belongs to the family of complex oxides. [12] New research carried out by CQT researchers suggest that standard protocols that measure the dimensions of quantum systems may return incorrect numbers. [11] Is entanglement really necessary for describing the physical world, or is it possible to have some post-quantum theory without entanglement? [10] A trio of scientists who defied Einstein by proving the nonlocal nature of quantum entanglement will be honoured with the John Stewart Bell Prize from the University of Toronto (U of T). [9] While physicists are continually looking for ways to unify the theory of relativity, which describes large-scale phenomena, with quantum theory, which describes small-scale phenomena, computer scientists are searching for technologies to build the quantum computer using Quantum Information. In August 2013, the achievement of "fully deterministic" quantum teleportation, using a hybrid technique, was reported. On 29 May 2014, scientists announced a reliable way of transferring data by quantum teleportation. Quantum teleportation of data had been done before but with highly unreliable methods. The accelerating electrons explain not only the Maxwell Equations and the Special Relativity, but the Heisenberg Uncertainty Relation, the Wave-Particle Duality and the electron's spin also, building the Bridge between the Classical and Quantum Theories. The Planck Distribution Law of the electromagnetic oscillators explains the electron/proton mass rate and the Weak and Strong Interactions by the diffraction patterns. The Weak Interaction changes the diffraction patterns by moving the electric charge from one side to the other side of the diffraction pattern, which violates the CP and Time reversal symmetry. The diffraction patterns and the locality of the self-maintaining electromagnetic potential explains also the Quantum Entanglement, giving it as a natural part of the Relativistic Quantum Theory and making possible to build the Quantum Computer with the help of Quantum Information.

CT Traces Coronavirus

An ongoing investigation into the novel coronavirus (2019-nCoV) outbreak has characterized the most common CT findings associated with the virus and identified possible markers of disease progression several days after the onset of symptoms. [27] To diagnose and treat diseases like cancer, scientists and doctors must understand how cells respond to different medical conditions and treatments. [26] Following its recent release of a massive database of chest X-rays, the US National Institutes of Health (NIH) has now made nearly 10,600 CT scans publicly available to support the development and testing of artificial intelligence (AI) algorithms for medical applications. [25] AI combined with stem cells promises a faster approach to disease prevention. Andrew Masterson reports. According to product chief Trystan Upstill, the news app "uses the best of artificial intelligence to find the best of human intelligence-the great reporting done by journalists around the globe." [23] Artificial intelligence is astonishing in its potential. It will be more transformative than the PC and the Internet. Already it is poised to solve some of our biggest challenges. [22] In the search for extraterrestrial intelligence (SETI), we've often looked for signs of intelligence, technology and communication that are similar to our own. [21] Call it an aMAZE -ing development: A U.K.-based team of researchers has developed an artificial intelligence program that can learn to take shortcuts through a labyrinth to reach its goal. In the process, the program developed structures akin to those in the human brain. [20] And as will be presented today at the 25th annual meeting of the Cognitive Neuroscience networks to enhance their understanding of one of the most elusive intelligence systems, the human brain.

Origin of New Emergent Coronavirus and Candida Fungal Disease– Terrestrial or Cosmic?

Authors: Edward J. Steele, Jiangwen Qu, N. Chandra Wickramasinghe, Reginald M. Gorczynski, Gensuke Tokoro, Robert Temple
Comments: 22 Pages. Penultimate prepublication version - to appear Advances in Genetics, Vol 106, 2020

We analyse the relevant genetic and epidemiological data of two recent and suddenly emerging diseases- the fungal disease due to Candida auris, and the common cold causing viral disease due to Coronavirus COVID-19. Analysis of all genetic, epidemiological and geophysical and astrophysical data suggest the alternate hypothesis of cosmic origins in both cases. The in-fall “signatures” are different yet distinctive implying clear Panspermic arrival of micro-organisms and viruses from space. For COVID-19 the evidence is now compelling that it arrived as a ‘pure culture’ via a meteorite, presumed carbonaceous meteorite, that struck North East China on October 11 2019. We also assume the viral dust debris carrying trillions of COVID-19 particles then made land fall in the Wuhan and related regions about a month to six weeks later. This resulted in first cases of the viral pneumonia due to COVID-19 emerging in Wuhan regions late November 2019-early December 2019. For COVID-19 the entire central region of China has been heavily physically contaminated, and that is why it has been described as a “Chernobyl-like” event. We make a number of future predictions – e.g. fragments of the meteorite viral dust cloud we think is now (February 16 2020) on the move into the South China Sea and making spot land fall over Japan.

An associate professor from Michigan State University has helped invent a potential treatment for coronary artery disease-a sub-microscopic scouring process he likens to "taking out the garbage." [23] Researchers at Oregon State University have developed an improved technique for using magnetic nanoclusters to kill hard-to-reach tumors. [22] MIT researchers have now come up with a novel way to prevent fibrosis from occurring, by incorporating a crystallized immunosuppressant drug into devices.

Bioengineers can design smart drugs for antibody and nanomaterial-based therapies to optimize drug efficiency for increasingly efficient, early-stage preclinical trials. [41] Many of these products use nanomaterials, but little is known about how these modern materials and their tiny particles interact with the environment and living things. [40] When chemists from the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw were starting work on a new material designed for the efficient production of nanocrystalline zinc oxide, they didn't expect any surprises. [39] Now writing in Light Science & Applications, Hamidreza Siampour and co-workers have taken a step forward in the field of integrated quantum plasmonics by demonstrating on-chip coupling between a single photon source and plasmonic waveguide. [38] Researchers at University of Utah Health developed a proof-of-concept technology using nanoparticles that could offer a new approach for oral medications. [37] Using scanning tunneling microscopy (STM), extremely high resolution imaging of the molecule-covered surface structures of silver nanoparticles is possible, even down to the recognition of individual parts of the molecules protecting the surface. [36] A fiber optic sensing system developed by researchers in China and Canada can peer inside supercapacitors and batteries to observe their state of charge. [35] The idea of using a sound wave in optical fibers initially came from the team's partner researchers at Bar-Ilan University in Israel. Joint research projects should follow. [34] Researchers at the Technion-Israel Institute of Technology have constructed a first-of-its-kind optic isolator based on resonance of light waves on a rapidly rotating glass sphere. [33] The micro-resonator is a two-mirror trap for the light, with the mirrors facing each other within several hundred nanometers. [32]

As the coronavirus outbreak shows, viruses are a constant threat to humanity. Vaccines are regularly developed and deployed against specific viruses, but that process takes a lot of time, doesn't help everyone who needs protection, and still leaves people exposed to new outbreaks and new viruses. [39] It's no coincidence that some of the worst viral disease outbreaks in recent years-SARS, MERS, Ebola, Marburg and likely the newly arrived 2019-nCoV virus-originated in bats. [38] An interdisciplinary team of researchers at Colorado State University has used computational chemistry, biochemistry and virology to uncover new information on how viruses such as West Nile, dengue and Zika replicate. [37] David Baker, Professor of Biochemistry and Director of the Institute for Protein Design at the University of Washington will speak about how algorithmic processes such as de novo design predict protein structures, protein folding mechanisms, and new protein functions. [36] A research team at Kobe University has developed a method of artificially controlling the anchorage position of target proteins in engineered baker's yeast (Saccharomyces cerevisiae). [35] Scientists have found a new way to home in on the proteins covering a particular cell's surface. The feat offers insight into how brain cells form intricate networks during development. [34]

A new technique could offer a targeted approach to fighting cancer: low-intensity pulses of ultrasound have been shown to selectively kill cancer cells while leaving normal cells unharmed. [34] Doctors have used focused ultrasound to destroy tumors without invasive surgery for some time. However, the therapeutic ultrasound used in clinics today indiscriminately damages cancer and healthy cells alike. [33] Scientists in the UK have shown for the first time that focused ultrasound from outside the body can improve the delivery of cancer drugs to tumors in humans. [32] The discovery could help us better understand aging and eventually could lead to new treatments for cancer.

A new collaborative study published by a research team from the Wayne State University School of Medicine, the CReATe Fertility Centre and the University of Massachusetts Amherst provides the first in-depth look at the microbiome of human sperm utilizing RNA sequencing with sufficient sensitivity to identify contamination and pathogenic bacterial colonization. [25] An LMU team has improved both the sensitivity and efficiency of a popular method for single-cell RNA sequencing, which yields a molecular fingerprint for individual cells based on their patterns of gene activity. [24] The goal is to find bits of DNA in common between the known relatives and the unidentified remains, suggesting both belong to a particular lineage. One analysis develops a profile that combines what's found at 23 spots in the DNA, for example.

[32] A particularly aggressive, metastasizing form of cancer, HER2-positive breast cancer, may be treated with nanoscopic particles "imprinted" with specific binding sites for the receptor molecule HER2. [31] UNC School of Medicine scientists created a powerful new "directed evolution" technique for the rapid development of scientific tools and new treatments for many diseases. [30] Scientists have been aware of this 'length problem' for a long time, but it was largely overlooked for most of the twentieth century. [29] Such emulsions are similar to the mixture that forms when you shake an oil-and-vinegar salad dressing, but with much smaller droplets. [28] Russian scientists found that nanocrystal tungsten trioxide can be used instead of barium for X-ray examinations and also in cancer treatment. [27] Medical advancements can come at a physical cost. Often following diagnosis and treatment for cancer and other diseases, patients' organs and cells can remain healed but damaged from the medical condition. [26]

Mucus is a protective, slimy secretion produced by goblet cells and which lines organs of the respiratory, digestive, and reproductive systems. [27] Scientists from EPFL's Institute of Bioengineering have discovered that the circadian clock and the cell-cycle are, in fact, synchronized. [26] Researchers at the University of Illinois at Chicago have identified a molecular switch that causes immune cells called macrophages to clean up cellular debris caused by infections instead of contributing to inflammation and tissue injury.

CAR T Treatments to Cancer

Authors: George Rajna
Comments: 44 Pages.

New cancer immunotherapies involve extracting a patient's T cells and genetically engineering them so they will recognize and attack tumors. [30] University of Wisconsin-Madison researchers have developed nanoparticles that, in the lab, can activate immune responses to cancer cells. [29] Small magnetic objects, which have been used successfully in technological applications such as data storage, are showing promise in the biomedical field. [28] Imaging at the scale of a single molecule has gained much recent research interest in diverse fields of molecular biology, physics and nanotechnology. [27] Physicists have developed a technique based on optical microscopy that can be used to create images of atoms on the nanoscale. [26] Researchers have designed a new type of laser called a quantum dot ring laser that emits red, orange, and green light. [25] The world of nanosensors may be physically small, but the demand is large and growing, with little sign of slowing. [24] In a joint research project, scientists from the Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI), the Technische Universität Berlin (TU) and the University of Rostock have managed for the first time to image free nanoparticles in a laboratory experiment using a highintensity laser source. [23] For the first time, researchers have built a nanolaser that uses only a single molecular layer, placed on a thin silicon beam, which operates at room temperature. [22] A team of engineers at Caltech has discovered how to use computer-chip manufacturing technologies to create the kind of reflective materials that make safety vests, running shoes, and road signs appear shiny in the dark. [21] In the September 23th issue of the Physical Review Letters, Prof. Julien Laurat and his team at Pierre and Marie Curie University in Paris (Laboratoire Kastler Brossel-LKB) report that they have realized an efficient mirror consisting of only 2000 atoms. [20] Physicists at MIT have now cooled a gas of potassium atoms to several nanokelvins-just a hair above absolute zero-and trapped the atoms within a two-dimensional sheet of an optical lattice created by crisscrossing lasers. Using a high-resolution microscope, the researchers took images of the cooled atoms residing in the lattice. [19]

RNA Direct Effect on DNA

Authors: George Rajna
Comments: 40 Pages.

Following a new collaboration between UiO and research groups in Nottingham and Oxford, it has now been revealed that RNA has a direct effect on DNA stability, according to Professor Klungland's research. [26] To dictate the biology of any cell, DNA in the cell's nucleus must be translated into corresponding strands of RNA. [25] An LMU team has improved both the sensitivity and efficiency of a popular method for single-cell RNA sequencing, which yields a molecular fingerprint for individual cells based on their patterns of gene activity. [24] The goal is to find bits of DNA in common between the known relatives and the unidentified remains, suggesting both belong to a particular lineage. One analysis develops a profile that combines what's found at 23 spots in the DNA, for example. [23] A new method allows researchers to systematically identify specialized proteins that unpack DNA inside the nucleus of a cell, making the usually dense DNA more accessible for gene expression and other functions. [22] Bacterial systems are some of the simplest and most effective platforms for the expression of recombinant proteins. [21] Now, in a new paper published in Nature Structural & Molecular Biology, Mayo researchers have determined how one DNA repair protein gets to the site of DNA damage. [20] A microscopic thread of DNA evidence in a public genealogy database led California authorities to declare this spring they had caught the Golden State Killer, the rapist and murderer who had eluded authorities for decades. [19] Researchers at Delft University of Technology, in collaboration with colleagues at the Autonomous University of Madrid, have created an artificial DNA blueprint for the replication of DNA in a cell-like structure. [18] An LMU team now reveals the inner workings of a molecular motor made of proteins which packs and unpacks DNA. [17]

Jumping Genes Stabilize DNA Folding

Authors: George Rajna
Comments: 39 Pages.

"Jumping genes"—bits of DNA that can move from one spot in the genome to another—are well-known for increasing genetic diversity over the long course of evolution. [23] Biology encodes information in DNA and RNA, which are complex molecules finely tuned to their functions. [22] When cells suffer DNA damage, they send out an SOS signal. When the repair crew arrives, the emergency signal is cancelled as it is no longer needed. [21] Now, in a new paper published in Nature Structural & Molecular Biology, Mayo researchers have determined how one DNA repair protein gets to the site of DNA damage. [20]

But the complicated mechanics of this collective cell movement-which are facilitated by rearrangements between each cell and its neighbors-have made it challenging for researchers to decipher what's actually driving it. [27] It's a remarkable choreography. In each of our bodies, more than 37 trillion cells tightly coordinate with other cells to organize into the numerous tissues and organs that make us tick. [26] A Virginia Commonwealth University researcher has developed a procedure for identifying the source of cells present in a forensic biological sample that could change how cell types are identified in samples across numerous industries.

Ultrasound Disrupts Cancer Cells

Authors: George Rajna
Comments: 53 Pages.

Medical engineers have proven that the unique internal structure of cancer cells can make them vulnerable to vibrations from specific frequencies of ultrasound. [34] Using the latest advances in imaging and computing, Johns Hopkins Medicine researchers have developed a framework that's able to reveal the structural and functional changes in the blood vessel network required for growth of a tumour. [33] Medical physicist Dr. Aswin Hoffmann and his team from the Institute of Radiooncology-OncoRay at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have combined magnetic resonance imaging (MRI) with a proton beam, thus demonstrating for the first time that in principle, this commonly used imaging method can work with particle beam cancer treatments. [32] Washington State University researchers for the first time have shown that they can use electrical fields to gain valuable information about the tiny, floating vesicles that move around in animals and plants and are critically important to many biological functions. [31] Finding a fast and inexpensive way to detect specific strains of bacteria and viruses is critical to food safety, water quality, environmental protection and human health. [30] In the perspective, Gabor and Song collect early examples in electron metamaterials and distil emerging design strategies for electronic control from them. [29] Lawrence Livermore National Laboratory (LLNL) researchers are working to make better electronic devices by delving into the way nanocrystals are arranged inside of them. [28] Self-assembly and crystallisation of nanoparticles (NPs) is generally a complex process, based on the evaporation or precipitation of NP-building blocks. [27] New nanoparticle-based films that are more than 80 times thinner than a human hair may help to fill this need by providing materials that can holographically archive more than 1000 times more data than a DVD in a 10-by-10-centimeter piece of film. [26] Researches of scientists from South Ural State University are implemented within this area. [25]

Molecular Nano-Patterning

Authors: George Rajna
Comments: 25 Pages.

Body movement, from the muscles in your arms to the neurons transporting those signals to your brain, relies on a massive collection of proteins called molecular motors. [19] Now, a team of researchers led by Dongsheng Li, a materials scientist at PNNL, and collaborators at the University of Michigan and the Chinese Academy of Sciences, have unlocked the secret to one of the most useful nanostructures: the five-fold twin. [18] The researchers have generated femtosecond laser pulses, with tailor-made, temporally varying polarizations, which are themselves chiral. [17] The scientists identified a shortlist, a kind of "periodic table" of the most designable knot types, i.e. those knots that could easily self-assemble under appropriate physical and chemical conditions. [16] Scientists have now observed for the first time how diamonds grow from seed at an atomic level, and discovered just how big the seeds need to be to kick the crystal growing process into overdrive. [15] The researchers engineered diamond strings that can be tuned to quiet a qubit's environment and improve memory from tens to several hundred nanoseconds, enough time to do many operations on a quantum chip. [14] Intel has announced the design and fabrication of a 49-qubit superconducting quantum-processor chip at the Consumer Electronics Show in Las Vegas. To improve our understanding of the so-called quantum properties of materials, scientists at the TU Delft investigated thin slices of SrIrO3, a material that belongs to the family of complex oxides. [12] New research carried out by CQT researchers suggest that standard protocols that measure the dimensions of quantum systems may return incorrect numbers. [11] Is entanglement really necessary for describing the physical world, or is it possible to have some post-quantum theory without entanglement? [10] A trio of scientists who defied Einstein by proving the nonlocal nature of quantum entanglement will be honoured with the John Stewart Bell Prize from the University of Toronto (U of T). [9] While physicists are continually looking for ways to unify the theory of relativity, which describes large-scale phenomena, with quantum theory, which describes small-scale phenomena, computer scientists are searching for technologies to build the quantum computer using Quantum Information. In August 2013, the achievement of "fully deterministic" quantum teleportation, using a hybrid technique, was reported. On 29 May 2014, scientists announced a reliable way of transferring data by quantum teleportation. Quantum teleportation of data had been done before but with highly unreliable methods. The accelerating electrons explain not only the Maxwell Equations and the Special Relativity, but the Heisenberg Uncertainty Relation, the Wave-Particle Duality and the electron's spin also, building the Bridge between the Classical and Quantum Theories. The Planck Distribution Law of the electromagnetic oscillators explains the electron/proton mass rate and the Weak and Strong Interactions by the diffraction patterns. The Weak Interaction changes the diffraction patterns by moving the electric charge from one side to the other side of the diffraction pattern, which violates the CP and Time reversal symmetry. The diffraction patterns and the locality of the self-maintaining electromagnetic potential explains also the Quantum Entanglement, giving it as a natural part of the Relativistic Quantum Theory and making possible to build the Quantum Computer with the help of Quantum Information.

Bacterial Cells in Photo-Emission

Authors: George Rajna
Comments: 26 Pages.

A team of Russian scientists working in cooperation with international colleagues used a new method combining visual microscopic observations and photoemission spectrum registration that can be used to create a map of the physical and chemical state of a cell surface. [16] Biochemists at the University of Illinois have isolated a protein supercomplex from a bacterial membrane that, like a battery, generates a voltage across the bacterial membrane. [15] Scientists from Moscow State University (MSU) working with an international team of researchers have identified the structure of one of the key regions of telomerase-a so-called "cellular immortality" ribonucleoprotein. [14] Researchers from Tokyo Metropolitan University used a light-sensitive iridium-palladium catalyst to make "sequential" polymers, using visible light to change how building blocks are combined into polymer chains. [13] Researchers have fused living and non-living cells for the first time in a way that allows them to work together, paving the way for new applications. [12] UZH researchers have discovered a previously unknown way in which proteins interact with one another and cells organize themselves. [11] Dr Martin Sweatman from the University of Edinburgh's School of Engineering has discovered a simple physical principle that might explain how life started on Earth. [10] Nearly 75 years ago, Nobel Prize-winning physicist Erwin Schrödinger wondered if the mysterious world of quantum mechanics played a role in biology. A recent finding by Northwestern University's Prem Kumar adds further evidence that the answer might be yes. [9] A UNSW Australia-led team of researchers has discovered how algae that survive in very low levels of light are able to switch on and off a weird quantum phenomenon that occurs during photosynthesis. [8] This paper contains the review of quantum entanglement investigations in living systems, and in the quantum mechanically modeled photoactive prebiotic kernel systems. [7] The human body is a constant flux of thousands of chemical/biological interactions and processes connecting molecules, cells, organs, and fluids, throughout the brain, body, and nervous system. Up until recently it was thought that all these interactions operated in a linear sequence, passing on information much like a runner passing the baton to the next runner. However, the latest findings in quantum biology and biophysics have discovered that there is in fact a tremendous degree of coherence within all living systems. The accelerating electrons explain not only the Maxwell Equations and the Special Relativity, but the Heisenberg Uncertainty Relation, the Wave-Particle Duality and the electron's spin also, building the Bridge between the Classical and Quantum Theories. The Planck Distribution Law of the electromagnetic oscillators explains the electron/proton mass rate and the Weak and Strong Interactions by the diffraction patterns. The Weak Interaction changes the diffraction patterns by moving the electric charge from one side to the other side of the diffraction pattern, which violates the CP and Time reversal symmetry. The diffraction patterns and the locality of the self-maintaining electromagnetic potential explains also the Quantum Entanglement, giving it as a natural part of the Relativistic Quantum Theory and making possible to understand the Quantum Biology.

[33] A team of researchers from Harvard University and Massachusetts Institute of Technology has found that they could use an optical tweezer array of laser-cooled molecules to observe ground state collisions between individual molecules.

[31] The optical tweezer is revealing new capabilities while helping scientists understand quantum mechanics, the theory that explains nature in terms of subatomic particles. [30] In the perspective, Gabor and Song collect early examples in electron metamaterials and distil emerging design strategies for electronic control from them. [29]

A Theory for Gravitational Killing Cancer Cells, Lightning Mechanism and Anomalous Magnetism of Muon 2G

Authors: Reginald B. Little
Comments: 33 Pages.

The death of cancer cells under zero gravity or simulated zero gravity has an unknown cause. A prior theory of gravity by fractional, reversible fissing of matter and fusing of space to target is presented for explaining this mystery of gravitational killing of cancer cells. With this new theory a new math of divergent differentiations and divergent integrations are outlined to explain mysteries. By the mechanism given the variation in source gravity as computed by the new math can thereby explain effects on biology as the biology and chemistry have divergent differentiations and divergent integrations, which couple source of gravities and couple changing gravities to surrounding spaces and targets in surrounding spaces. Greater effects of gravities in nano-scales than molecular scales are reasoned as nano-sizes have mass effects and greater collectivity relative to molecular scales. The mechanism also postulates superluminosity of rare with slowing to luminous with denseness (space reversal) for explaining inertia, denseness and back and forth time reversal. The loss of inertia due to space reversal is reasoned! Mass to energy and vice versa dynamics are involved relativistically. By such new mechanics there are differences in denseness as the superlumes fiss to rare so surrounding rare can couple and the superluminous rare concentrates to slow so as to couple to dense. There are limits of such superluminosity as by the vast distances and the vast, composite, dense spaces of matter and the slowness (inertia). These new mechanics of composite matter/space manifest group dispersion (by new divergent calculus) as provided by hidden mechanics as by self-interacting self-deforming conformations to explain observable phase dispersed (older calculus). The observables are manifested by phase dispersions of matter and space as by new divergent calculus via constructive self interactions. The new math is contrasted with the Newtonian integrals and derivatives, which are more finite in actions and consequences whereas the divergent integrals and divergent differentiations are more infinities in actions and consequences. If dynamic infinity and count infinity, then the counting and mechanics can be as demonstrated here by many infinities or counter infinities.

Synthetic Nanopores made from DNA

Authors: George Rajna
Comments: 27 Pages.

In 2015, the first commercial nanopore DNA sequencing device was introduced by Oxford Nanopore Technologies. [15] In the journal PNAS this week, researchers at Boston Children's Hospital and MIT show that these mini-antibodies, shrunk further to create so-called nanobodies, may help solve a problem in the cancer field: making CAR T-cell therapies work in solid tumors. [14] What if the brain could detect its own disease? Researchers have been trying to create a material that "thinks" like the brain does, which would be more sensitive to early signs of neurological diseases such as Parkinson's. [13] University Professor of Applied Physics Stephen Arnold and his team at the New York University Tandon School of Engineering have made a discovery that could lead to Star Trek-like biosensor devices capable of flagging the barest presence in blood of a specific virus or antibody, or protein marker for a specific cancer; or sniffing out airborne chemical warfare agents while they are still far below toxic levels. [12] Lead researcher Dr Jonathan Breeze, from Imperial's Department of Materials, said: "This breakthrough paves the way for the widespread adoption of masers and opens the door for a wide array of applications that we are keen to explore. We hope the maser will now enjoy as much success as the laser." [11] Japanese researchers have optimized the design of laboratory-grown, synthetic diamonds. [10] Nearly 75 years ago, Nobel Prize-winning physicist Erwin Schrödinger wondered if the mysterious world of quantum mechanics played a role in biology. A recent finding by Northwestern University's Prem Kumar adds further evidence that the answer might be yes. [9] A UNSW Australia-led team of researchers has discovered how algae that survive in very low levels of light are able to switch on and off a weird quantum phenomenon that occurs during photosynthesis. [8] This paper contains the review of quantum entanglement investigations in living systems, and in the quantum mechanically modeled photoactive prebiotic kernel systems. [7] The human body is a constant flux of thousands of chemical/biological interactions and processes connecting molecules, cells, organs, and fluids, throughout the brain, body, and nervous system. Up until recently it was thought that all these interactions operated in a linear sequence, passing on information much like a runner passing the baton to the next runner. However, the latest findings in quantum biology and biophysics have discovered that there is in fact a tremendous degree of coherence within all living systems. The accelerating electrons explain not only the Maxwell Equations and the Special Relativity, but the Heisenberg Uncertainty Relation, the Wave-Particle Duality and the electron's spin also, building the Bridge between the Classical and Quantum Theories. The Planck Distribution Law of the electromagnetic oscillators explains the electron/proton mass rate and the Weak and Strong Interactions by the diffraction patterns. The Weak Interaction changes the diffraction patterns by moving the electric charge from one side to the other side of the diffraction pattern, which violates the CP and Time reversal symmetry. The diffraction patterns and the locality of the self-maintaining electromagnetic potential explains also the Quantum Entanglement, giving it as a natural part of the Relativistic Quantum Theory and making possible to understand the Quantum Biology.

Why Does Menstruation Cycle Synchronize with Moon Cycle?

Authors: Wan-Chung Hu
Comments: 2 Pages.

Primates and bats are mammals with menstruation cycle. The menstruation cycle is around 28-35 days in most primates. The cycle is synchronizing with moon period. Why does menstruation cycle synchronize moon cycle? Here, I propose that the phenomenon is because primates and bats need to increase the change of fertilization. Primates as well as bats can stand with two legs or hang with two legs. In majority of time, they maintain the straight position of their bodies. In this position, sperms will need swim against gravity toward Fallopian tube after intercourse. They will need to take 1-12 hours to meet the oocytes. Straight body position will increase the difficulty to let sperms to meet oocytes. Thus, gravity force can affect the chance of fertilization. Moon is the major source of tidal force. The moon cycle will affect the magnitude of gravity force. Thus, primates and bats evolve menstruation cycles to let the ovulation occur during the less-gravity period. So, menstruation cycle is synchronizing the moon cycle. That is the reason why primates and bats, not other mammals, have menstruation cycles.

Superbugs Destroyed by Molecular Drills

Authors: George Rajna
Comments: 26 Pages.

Molecular drills have gained the ability to target and destroy deadly bacteria that have evolved resistance to nearly all antibiotics. In some cases, the drills make the antibiotics effective once again. [19] Now, a team of researchers led by Dongsheng Li, a materials scientist at PNNL, and collaborators at the University of Michigan and the Chinese Academy of Sciences, have unlocked the secret to one of the most useful nanostructures: the five-fold twin. [18] The researchers have generated femtosecond laser pulses, with tailor-made, temporally varying polarizations, which are themselves chiral. [17] The scientists identified a shortlist, a kind of "periodic table" of the most designable knot types, i.e. those knots that could easily self-assemble under appropriate physical and chemical conditions.

Self-Cleaning Surface Repels Superbugs

A team of researchers at McMaster University has developed a self-cleaning surface that can repel all forms of bacteria, preventing the transfer of antibiotic-resistant superbugs and other dangerous bacteria in settings ranging from hospitals to kitchens. [20] Molecular drills have gained the ability to target and destroy deadly bacteria that have evolved resistance to nearly all antibiotics. In some cases, the drills make the antibiotics effective once again. [19] Now, a team of researchers led by Dongsheng Li, a materials scientist at PNNL, and collaborators at the University of Michigan and the Chinese Academy of Sciences, have unlocked the secret to one of the most useful nanostructures: the five-fold twin.

[17] The scientists identified a shortlist, a kind of "periodic table" of the most designable knot types, i.e. those knots that could easily self-assemble under appropriate physical and chemical conditions. [16] Scientists have now observed for the first time how diamonds grow from seed at an atomic level, and discovered just how big the seeds need to be to kick the crystal growing process into overdrive. [15] The researchers engineered diamond strings that can be tuned to quiet a qubit's environment and improve memory from tens to several hundred nanoseconds, enough time to do many operations on a quantum chip. [14] Intel has announced the design and fabrication of a 49-qubit superconducting quantum-processor chip at the Consumer Electronics Show in Las Vegas. To improve our understanding of the so-called quantum properties of materials, scientists at the TU Delft investigated thin slices of SrIrO3, a material that belongs to the family of complex oxides. [12] New research carried out by CQT researchers suggest that standard protocols that measure the dimensions of quantum systems may return incorrect numbers. [11] Is entanglement really necessary for describing the physical world, or is it possible to have some post-quantum theory without entanglement? [10] A trio of scientists who defied Einstein by proving the nonlocal nature of quantum entanglement will be honoured with the John Stewart Bell Prize from the University of Toronto (U of T). [9] While physicists are continually looking for ways to unify the theory of relativity, which describes large-scale phenomena, with quantum theory, which describes small-scale phenomena, computer scientists are searching for technologies to build the quantum computer using Quantum Information. In August 2013, the achievement of "fully deterministic" quantum teleportation, using a hybrid technique, was reported. On 29 May 2014, scientists announced a reliable way of transferring data by quantum teleportation. Quantum teleportation of data had been done before but with highly unreliable methods. The accelerating electrons explain not only the Maxwell Equations and the Special Relativity, but the Heisenberg Uncertainty Relation, the Wave-Particle Duality and the electron's spin also, building the Bridge between the Classical and Quantum Theories.

Children's Research Hospital scientists have identified a new therapeutic strategy that enhanced cancer immunotherapy, slowed tumor growth and extended the lives of mice with cancer. [34] Using the latest advances in imaging and computing, Johns Hopkins Medicine researchers have developed a framework that's able to reveal the structural and functional changes in the blood vessel network required for growth of a tumour. [33] Medical physicist Dr. Aswin Hoffmann and his team from the Institute of Radiooncology-OncoRay at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have combined magnetic resonance imaging (MRI) with a proton beam, thus demonstrating for the first time that in principle, this commonly used imaging method can work with particle beam cancer treatments. [32] Washington State University researchers for the first time have shown that they can use electrical fields to gain valuable information about the tiny, floating vesicles that move around in animals and plants and are critically important to many biological functions. [31] Finding a fast and inexpensive way to detect specific strains of bacteria and viruses is critical to food safety, water quality, environmental protection and human health. [30] In the perspective, Gabor and Song collect early examples in electron metamaterials and distil emerging design strategies for electronic control from them. [29] Lawrence Livermore National Laboratory (LLNL) researchers are working to make better electronic devices by delving into the way nanocrystals are arranged inside of them. [28] Self-assembly and crystallisation of nanoparticles (NPs) is generally a complex process, based on the evaporation or precipitation of NP-building blocks. [27] New nanoparticle-based films that are more than 80 times thinner than a human hair may help to fill this need by providing materials that can holographically archive more than 1000 times more data than a DVD in a 10-by-10-centimeter piece of film. [26] Researches of scientists from South Ural State University are implemented within this area. [25]

Researchers in Dana-Farber's cBio Center have now demonstrated a powerful 'experimental evolution' method to discover details of protein shape and function, and the method may find uses across a very broad spectrum of biomedical research.

Chip-Based Optical Sensor Detects Cancer

For the first time, researchers have used a chip-based sensor with an integrated laser to detect very low levels of a cancer protein biomarker in a urine sample. [30] Researchers at the National Institute of Standards and Technology (NIST) have made a silicon chip that distributes optical signals precisely across a miniature brain-like grid, showcasing a potential new design for neural networks. [29] Researchers have shown that it is possible to train artificial neural networks directly on an optical chip. [28] Scientists from Russia, Estonia and the United Kingdom have created a new method for predicting the bioconcentration factor (BCF) of organic molecules. [27] Predictions for an AI-dominated future are increasingly common, but Antoine Blondeau has experience in reading, and arguably manipulating, the runes-he helped develop technology that evolved into predictive texting and Apple's Siri. [26] Artificial intelligence can improve health care by analyzing data from apps, smartphones and wearable technology. [25] Now, researchers at Google's DeepMind have developed a simple algorithm to handle such reasoning-and it has already beaten humans at a complex image comprehension test. [24] A marimba-playing robot with four arms and eight sticks is writing and playing its own compositions in a lab at the Georgia Institute of Technology. The pieces are generated using artificial intelligence and deep learning. [23] Now, a team of researchers at MIT and elsewhere has developed a new approach to such computations, using light instead of electricity, which they say could vastly improve the speed and efficiency of certain deep learning computations. [22] Physicists have found that the structure of certain types of quantum learning algorithms is very similar to their classical counterparts-a finding that will help scientists further develop the quantum versions. [21] We should remain optimistic that quantum computing and AI will continue to improve our lives, but we also should continue to hold companies, organizations, and governments accountable for how our private data is used, as well as the technology's impact on the environment.

Protein-like molecules called "polypeptoids" (or "peptoids," for short) have great promise as precision building blocks for creating a variety of designer nanomaterials, like flexible nanosheets-ultrathin, atomic-scale 2-D materials.

In addition, owing to the achieved ligands ordering, we are able to pack a lot of active drug particles on a small carrier," adds Professor Lewinski. [28] Nanotechnology may provide an effective treatment for Parkinson’s disease, a team of researchers suggests. [27] Recent research from Kumamoto University in Japan has revealed that polyoxometalates (POMs), typically used for catalysis, electrochemistry, and photochemistry, may also be used in a technique for analyzing quantum dot (QD) photoluminescence (PL) emission mechanisms.

Authors: George Rajna
Comments: 78 Pages.

A new imaging technique developed by Biwei Yin and interdisciplinary researchers at the Massachusetts General Hospital and Harvard Medical School in the U.S., provides resolution at the subcellular-level to image the heart's vascular system. [47] The key to ghost imaging is to use two or more correlated beams of particles. [46] Physicists at the University of Alberta in Canada have developed a new way to build quantum memories, a method for storing delicate quantum information encoded into pulses of light. [45] Now, an Australian research team has experimentally realised a crucial combination of these capabilities on a silicon chip, bringing the dream of a universal quantum computer closer to reality. [44] A theoretical concept to realize quantum information processing has been developed by Professor Guido Burkard and his team of physicists at the University of Konstanz. [43] As the number of hacks and security breaches rapidly climbs, scientists say there may be a way to make a truly unhackable network by using the laws of quantum physics. [42] This world-first nanophotonic device, just unveiled in Nature Communications, encodes more data and processes it much faster than conventional fiber optics by using a special form of 'twisted' light. [41] Purdue University researchers created a new technique that would increase the secret bit rate 100-fold, to over 35 million photons per second. [40] Physicists at The City College of New York have used atomically thin two-dimensional materials to realize an array of quantum emitters operating at room temperature that can be integrated into next generation quantum communication systems. [39] Research in the quantum optics lab of Prof. Barak Dayan in the Weizmann Institute of Science may be bringing the development of such computers one step closer by providing the "quantum gates" that are required for communication within and between such quantum computers.

Authors: George Rajna
Comments: 42 Pages.

In an effort to increase access to long-acting contraception, a US-based research team has developed a microneedle patch that slowly releases contraceptive hormone for more than a month, and generates no biohazardous sharps waste (Science Advances 10.1126/sciadv.aaw8145). [26] Researchers at the UPV/EHU-University of the Basque Country have developed a biomedical device for cell immune-isolation (microcapsules) with luminescence for in vivo tracking. [25] Using x-rays to reveal the atomic-scale 3-D structures of proteins has led to countless advances in understanding how these molecules work in bacteria, viruses, plants, and humans—and has guided the development of precision drugs to combat diseases such as cancer and AIDS.

Physical Principles in Revealing the Working Mechanisms of Brain, Part One

Authors: Nicolae Mazilu
Comments: 50 Pages.

This work is addressed to a wide range of scientists who approach the research of the human brain from different points of view. Our main point is that no matter of the angle of approach in the brain research, a scientist has to be aware of the physical possibility of working of the brain. We describe this possibility by modeling the brain as light. The essential physical property of this model is fractality. It will be physically explained for the light itself and then applied as such to the brain. The main brain functions: the memory, acquiring information, and handling this information are then explained as scale transient fractal phenomena. This physical model is thereby useful in guiding any research on brain, no matter of its nature.

Photon in Organic Solar Cells

Authors: George Rajna
Comments: 56 Pages.

Organic solar cells are steadily improving as new materials are developed for the active layer, particularly when materials are stacked in a bulk heterojunction design that takes advantage of multiple combined absorption windows to use photons at more parts of the spectrum. [37] The experiments showed that quantum light can be used to probe enzyme activities in real time without perturbing the sample. [36] The biological technique of 'optogenetics' uses light to control cells within living tissues that have been genetically modified to be light-sensitive. [35]

Cutting Nanoparticles to Size

Authors: George Rajna
Comments: 47 Pages.

In a new study, published in Nature Communications, researchers from the University of Birmingham and the University of Bath have demonstrated a technique that will allow chemists to more closely control the size and shape of nanoparticles. [33] Rice University scientists have found revealing information where light from a molecule meets light from a nanoparticle. [32] A University of Wyoming researcher and his team have shown, for the first time, the ability to globally align single-wall carbon nanotubes along a common axis. [31] The fight against global antibiotic resistance has taken a major step forward with scientists discovering a concept for fabricating nanomeshes as an effective drug delivery system for antibiotics. [30] The solution consisting of colloidal quantum dots is inkjet-printed, creating active photosensitive layer of the photodetector. [29] I'm part of a group of nanotechnology and neuroscience researchers at the University of Washington investigating how quantum dots behave in the brain. [28] Nanotechnology may provide an effective treatment for Parkinson's disease, a team of researchers suggests. [27] Recent research from Kumamoto University in Japan has revealed that polyoxometalates (POMs), typically used for catalysis, electrochemistry, and photochemistry, may also be used in a technique for analyzing quantum dot (QD) photoluminescence (PL) emission mechanisms. [26] Researchers have designed a new type of laser called a quantum dot ring laser that emits red, orange, and green light. [25] The world of nanosensors may be physically small, but the demand is large and growing, with little sign of slowing. [24] In a joint research project, scientists from the Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI), the Technische Universität Berlin (TU) and the University of Rostock have managed for the first time to image free nanoparticles in a laboratory experiment using a highintensity laser source. [23] For the first time, researchers have built a nanolaser that uses only a single molecular layer, placed on a thin silicon beam, which operates at room temperature. [22]

Comments: 49 Pages.

In a new study, Karthik Pushpavanam and an interdisciplinary team of researchers in the departments of Chemical Engineering, Molecular Sciences, Banner MD Anderson Cancer Center and Arizona Veterinary Oncology in the U.S. has described a novel gel-based nanosensor. The technology allows colorimetric detection and quantification of topographical radiation dose profiles during radiotherapy.

[25] Scientists at the Max Planck Institute for Plant Breeding Research in Cologne have now discovered how a protein called LMI1 can control leaf growth and shape. [24] One way we might actually prove our biological complexity is to look at the number of different proteins that our bodies can produce for building all our different types of cells and the other things they need. [23] A new method allows researchers to systematically identify specialized proteins that unpack DNA inside the nucleus of a cell, making the usually dense DNA more accessible for gene expression and other functions.
