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.

A large team of researchers affiliated with multiple institutions in and around Hangzhou, China, has taken a very large step toward the creation of a comprehensive human single-cell atlas. [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. [24] A novel technique developed by researchers at the ARC Centre of Excellence for Nanoscale BioPhotonics (CNBP) will help shine new light on biological questions by improving the quality and quantity of information that can be extracted in fluorescence microscopy. [23] Micro-computed tomography or "micro-CT" is X-ray imaging in 3-D, by the same method used in hospital CT (or "CAT") scans, but on a small scale with massively increased resolution.

[12] Thumb through any old science textbook, and you'll likely find RNA described as little more than a means to an end, a kind of molecular scratch paper used to construct the proteins encoded in DNA. [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.

[13] ETH scientists have been able to prove that a protein structure widespread in nature-the amyloid-is theoretically capable of multiplying itself. [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.

[42] Plasma particle accelerators more powerful than existing machines could help probe some of the outstanding mysteries of our universe, as well as make leaps forward in cancer treatment and security scanning-all in a package that's around a thousandth of the size of current accelerators. [41] The Department of Energy's SLAC National Accelerator Laboratory has started to assemble a new facility for revolutionary accelerator technologies that could make future accelerators 100 to 1,000 times smaller and boost their capabilities. [40] The authors designed a mechanism based on the deployment of a transport barrier to confine the particles and prevent them from moving from one region of the accelerator to another. "There is strong experimental evidence that there is indeed some new physics lurking in the lepton sector," Dev said.

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.

[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.

[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.

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. [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]

e evidences showing major role of Vitamin D3 in human immune system and its potential use for novel corona virus treatment. Our argument is based on research finding that corona virus has viral envelope glycoproteins. In this regard, Vitamin D3 proves to offer various beneficial effects, including immunomodulatory effect, in order to break the glycoproteins envelope of the virus. One of the greatest benefit of vitamin D3 is the fact that it is easy to get 10,000 - 20,000 IU of daily intake requirement, by sunbathing for more or less twenty minutes. Such a method is likely applicable in many tropical countries.

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.

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. [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.

Graphene Identify Bacteria Using a single atom-thick sheet of graphene to track the electronic signals inherent in biological structures, a team led by Boston College researchers has developed a platform to selectively identify deadly strains of bacteria, an advance that could lead to more accurate targeting of infections with appropriate antibiotics, the team reported in the journal Biosensors and Bioelectronics.

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. [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 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. [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.

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. [30] Small vessel vasculitis-inflammation of the small blood vessels-appears as a stain of tiny, red dots covering the skin that, depending on the severity, can evolve into painful pustules or ulcers.

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 Hubei 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.

Set against a piece of black construction paper, the wings of the male cattleheart butterfly look even blacker than black.

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.

Utrecht scientists have succeeded in measuring the mass of individual molecules. By modifying an existing mass spectrometer and developing special software, the researchers succeeded in making ultra-sensitive measurements. [22] In a new study that supports the trend of DNA-based information carriers, scientists have engineered a DNA navigator system that can perform single-molecule, parallel, depth-first search operations on a two-dimensional origami platform. [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. [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] Chemist Ivan Huc finds the inspiration for his work in the molecular principles that underlie biological systems. [16] What makes particles self-assemble into complex biological structures? [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]

The team started with nanoparticles of iron oxide, which have already found use in both MRI and MPI, and joined them to the nerve-binding peptide NP41. [42] Northeastern chemical engineer Thomas Webster, who specializes in developing nano-scale medicine and technology to treat diseases, is part of a contingency of scientists that are contributing ideas and technology to the Centers for Disease Control and Prevention to fight the COVID-19 outbreak. [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). [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]

[56] A team of researchers from Nanyang Technological University, Singapore (NTU Singapore) and Griffith University in Australia have constructed a prototype quantum device that can generate all possible futures in a simultaneous quantum superposition.

[54] Researchers have developed a new device that can measure and control a nanoparticle trapped in a laser beam with unprecedented sensitivity. [53] Researchers have discovered a 'blind spot' in atomic force microscopy-a powerful tool capable of measuring the force between two atoms, imaging the structure of individual cells and the motion of biomolecules.

A team of researchers from Universidad de Buenos Aires, Museo Argentino de Ciencias Naturales and the University of Münster accurately estimated the size of a white-tipped plantcutter bird by studying nothing but its song. [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.

[24] A novel technique developed by researchers at the ARC Centre of Excellence for Nanoscale BioPhotonics (CNBP) will help shine new light on biological questions by improving the quality and quantity of information that can be extracted in fluorescence microscopy. [23] Micro-computed tomography or "micro-CT" is X-ray imaging in 3-D, by the same method used in hospital CT (or "CAT") scans, but on a small scale with massively increased resolution. [22] A new experimental method permits the X-ray analysis of amyloids, a class of large, filamentous biomolecules which are an important hallmark of diseases such as Alzheimer's and Parkinson's. [12] Thumb through any old science textbook, and you'll likely find RNA described as little more than a means to an end, a kind of molecular scratch paper used to construct the proteins encoded in DNA. [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.

Dementia Detection PET with FDG and various other radiotracers has been used to attempt to diagnose the early onset of Alzheimer's and dementia. [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]

The next step of the research group is to find more molecules that biologically inhibits the POLA1 gene and which, in combination with other substances, may be used in the treatment of cancer patients. [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.
