Authors: Zyryanova N.V., Savelyev I., Myakishev-Rempel M.
Comments: 7 Pages. In English и на русском языке

Uncentrosymmetric oxygen tetrahedrons and octahedrons produce piezoelectricity. In main biological molecules there are phosphorus-oxygen tetrahedrons. Biological molecules is uncentrosymmetric, and phosphorus-oxygen tetrahedrons enhance its reactivity. We suppose that oxygen octahedrons and tetrahedrons produce electricity in living organisms, and the electricity is condition for many biological phenomenon.

Nanomachines Fight Cancer

Authors: George Rajna
Comments: 30 Pages.

Scientists from ITMO in collaboration with international colleagues have proposed new DNA-based nanomachines that can be used for gene therapy for cancer. [19] CRISPR is a technique that is revolutionizing biomedical research through high-precision genome editing. [18] The DNA molecules are chiral, which means they can exist in two forms which are mirror images, like a left and right hand. The phenomenon was dubbed "chiral induced spin selectivity" (CISS), and over the last few years, several experiments were published allegedly showing this CISS effect, even in electronic devices.

Radio Frequency Water Treatment: Phenomenon and Explanation of Enhanced Water Transport in a Plant.

Authors: Andrew Holster
Comments: 38 Pages.

Radio frequency electromagnetic treatment of water using a commercial device (Vi Aqua Plantmate) was found to increase water transport in a plant by 20% - 35%, under suitable conditions. The experimental phenomenon is briefly presented, and the problem of explaining the effects is then examined. It is concluded that the EM treatment has long-lasting effects on water, and inferred that this reflects a structural property of the water. This water structure enhances capillarity and osmosis. It is suggested this is related to EZ structure. (Converted Powerpoint presentation from the 2017 Water Conference, Bulgaria).

Molecular DNA Repair

Authors: George Rajna
Comments: 38 Pages.

Using a piece of molecular "Velcro" to attach a light-emitting probe to a protein molecule, University of Wollongong (UOW) researchers have unlocked the mystery of how an important protein goes about repairing damaged DNA in bacteria, with implications for understanding how antibiotic resistance develops. [21] In new research, Hao Yan of Arizona State University and his colleagues describe an innovative DNA walker, capable of rapidly traversing a prepared track. [20] Just like any long polymer chain, DNA tends to form knots. Using technology that allows them to stretch DNA molecules and image the behavior of these knots, MIT researchers have discovered, for the first time, the factors that determine whether a knot moves along the strand or "jams" in place.

Longer Wavelength Optical Coherence Tomography

Authors: George Rajna
Comments: 29 Pages.

Optical coherence tomography (OCT) is a light-based imaging technique currently used in clinical diagnostics to examine organs in vivo. [17] This new approach illuminates the origin of surface electromagnetic waves and explains why these waves appear at interfaces where one of the medium parameters (dielectric permittivity or magnetic permeability) changes its sign. [16] A team of physicists headed by Professor Sebastian Reineke of TU Dresden has developed a new method of storing information in fully transparent plastic foils. [15] A new electron microscopy technique that detects the subtle changes in the weight of proteins at the nanoscale—while keeping the sample intact—could open a new pathway for deeper, more comprehensive studies of the basic building blocks of life.

The Theory of Dove-Like Particles

Authors: Sun Zuodong
Comments: 38 Pages.

An enlightening viewpoint based on the theory of brain cell activation is to explore the pathogenesis and mechanism of sporadic Alzheimer's disease (AD) at molecular level by applying the principles of cell physics and biology. Its purpose is to coordinate and unify the existing theories of AD etiology and to solve the problems that have puzzled the research field of neurodegenerative diseases for a long time. Basic Contents: Excessive cations are transferred from extracellular to intracellular, and compete with potassium ions on the inner surface of the cell membrane. As a result, the action potential produced can not activate calcium channels normally, leading to abnormal apoptosis of brain cells. Amyloid plaques are the remains of abnormal apoptotic brain cells. Amyloid plaques are aggregated by van der Waals force and electrostatic attraction between amyloid plaques. The interstitium is amyloid protein. Brain cells consist of neurons, microglia and astrocytes in turn. Most of the spotted nuclei in the remains are cations. Applicable but not limited to neurodegenerative diseases such as Alzheimer's disease, physical means should be preferred to solve such diseases.

Comments: 98 Pages.

In a new method, materials scientists Boliang Jia and colleagues at the departments of mechanical engineering and robotics presented a printable biocompatible superlens placed directly on objects of interest to observe subdiffraction-limited features (resolution beyond the diffraction limit). [54] Physicists have also devised photonic topological insulators, synthetic materials that impart light waves with distinct topological features, allowing light (rather than electric currents) to flow via topological surface states. [53] "This research highlights the cutting-edge research being done at WVU, and we are very excited to see their work appear in the very high-profile journal Nature Communications." [52]
