Regenerative Biology Restore Mucus

Authors: George Rajna
Comments: 44 Pages.

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]

Michigan State University and Stanford University scientists have invented a nanoparticle that eats away—from the inside out—portions of plaques that cause heart attacks. [34] Another collaborative project from a nanoparticles expert at The University of Texas at Arlington has yielded promising results in the search for more effective, targeted cancer treatments. [33] Automated radiotherapy planning is a boon for medical physicists and dosimetrists, radiotherapy departments, and patients themselves – according to a team at Cone Health Cancer Center. [32]

Laser Diagnoses at a Distance

Authors: George Rajna
Comments: 26 Pages.

Fully contact-free laser ultrasound (LUS) imaging has been demonstrated in humans by researchers at Massachusetts Institute of Technology (MIT), in collaboration with MIT Lincoln Laboratory. Xiang Zhang and colleagues used an infrared laser to generate sound waves at the tissue surface of volunteers' forearms. [14] Optical Mammography, or OM, which uses harmless red or infrared light, has been developed for use in conjunction with X-rays for diagnosis or monitoring in cases demanding repeated imaging where high amounts of ionizing radiation should be avoided. [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.

Authors: George Rajna

The growing clinical application of stereotactic radiosurgery (SRS) for the treatment of metastatic tumours in the brain presents a significant dosimetric and quality assurance (QA) challenge for medical physicists and their clinical colleagues. [15] Fully contact-free laser ultrasound (LUS) imaging has been demonstrated in humans by researchers at Massachusetts Institute of Technology (MIT), in collaboration with MIT Lincoln Laboratory.

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]

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. [25] Working with mouse and human tissue, Johns Hopkins Medicine researchers report new evidence that a protein pumped out of some—but not all—populations of "helper" cells in the brain, called astrocytes, plays a specific role in directing the formation of connections among neurons needed for learning and forming new memories.

Discovery How Cells Move

Authors: George Rajna
Comments: 49 Pages.

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. [25] In work at the National Institute of Standards and Technology (NIST) and the University of Maryland in College Park, researchers have devised and demonstrated a new way to measure free energy.

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 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.

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.

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.

[33] Scientists at Tokyo Institute of Technology proposed new quasi-1-D materials for potential spintronic applications, an upcoming technology that exploits the spin of electrons. [32] They do this by using "excitons," electrically neutral quasiparticles that exist in insulators, semiconductors and in some liquids. [31] Researchers at ETH Zurich have now developed a method that makes it possible to couple such a spin qubit strongly to microwave photons. [30] Quantum dots that emit entangled photon pairs on demand could be used in quantum communication networks. [29] Researchers successfully integrated the systems-donor atoms and quantum dots. [28] A team of researchers including U of A engineering and physics faculty has developed a new method of detecting single photons, or light particles, using quantum dots. [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]

Extend Lifespan by 500%

Authors: George Rajna
Comments: 61 Pages.

The increase in lifespan would be the equivalent of a human living for 400 or 500 years, according to one of the scientists. [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. [31]

[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. [31] A research team at the University of Delaware, led by Emily Day, an assistant professor of biomedical engineering, is laying the groundwork for a method to inhibit cancer-promoting genes in cancer cells while leaving healthy cells intact. [30] Researchers have moved closer to the real-time verification of hadron therapy, demonstrating the in vivo accuracy of simulations that predict particle range in the patient. [29] A biomimetic nanosystem can deliver therapeutic proteins to selectively target cancerous tumors, according to a team of Penn State researchers. [28] Sunlight is essential for all life, and living organisms have evolved to sense and respond to light. [27] Using X-ray laser technology, a team led by researchers of the Paul Scherrer Institute PSI has recorded one of the fastest processes in biology. [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. [25] In work at the National Institute of Standards and Technology (NIST) and the University of Maryland in College Park, researchers have devised and demonstrated a new way to measure free energy.

Authors: George Rajna
Comments: 59 Pages.

In a study published Thursday in the journal Current Biology, Güler and his colleagues demonstrate that the pleasure center of the brain that produces the chemical dopamine, and the brain's separate biological clock that regulates daily physiological rhythms, are linked, and that high-calorie foods-which bring pleasure-disrupt normal feeding schedules, resulting in overconsumption.

Snake-Like Proteins Wrangle DNA

Authors: George Rajna
Comments: 36 Pages.

Members of Rice's Center for Theoretical Biological Physics (CTBP) are taking a deep dive into the dynamics of essential proteins that help DNA fold into its compact, functional form in chromosomes. [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]
