Published New findings indicate gene-edited rice might survive in Martian soil
(via sciencedaily.com) Original source New research suggests future Martian botanists may be able to grow gene-edited rice on Mars.
Published Tunneling electrons
(via sciencedaily.com) Original source By superimposing two laser fields of different strengths and frequency, the electron emission of metals can be measured and controlled precisely to a few attoseconds. Physicists have shown that this is the case. The findings could lead to new quantum-mechanical insights and enable electronic circuits that are a million times faster than today.
Published Near-universal T cell immunity towards a broad range of bacteria
(via sciencedaily.com) Original source Typically T cells of the immune system respond to a specific feature (antigen) of a microbe, thereby generating protective immunity. Scientists have discovered an exception to this rule. Namely, a group of divergent bacterial pathogens, including pneumococci, all share a small highly conserved protein sequence, which is both presented and recognized by human T cells in a conserved population-wide manner.
Published Luring the virus into a trap
(via sciencedaily.com) Original source Viruses like influenza A and Ebola invade human cells in a number of steps. Research teams investigated the final stages of viral penetration using electron tomography and computer simulations. So-called fusion pores, through which the viral genome is released into the host cell, play a central role in these processes. If they can be prevented from forming, the virus is also blocked. The Heidelberg scientists describe previously unknown mechanisms, which might lead to new approaches to prevent infections.
Published Researchers reveal an ancient mechanism for wound repair
(via sciencedaily.com) Original source The study is the first to identify a damage response pathway that is distinct from but parallel to the classical pathway triggered by pathogens.
Published Scientists have full state of a quantum liquid down cold
(via sciencedaily.com) Original source A team of physicists has illuminated certain properties of quantum systems by observing how their fluctuations spread over time. The research offers an intricate understanding of a complex phenomenon that is foundational to quantum computing.
Published Researchers reveal a map to study novel form of cell-to-cell communication
(via sciencedaily.com) Original source An international team of researchers lays the foundation to examine how extracellular RNA and its carrier proteins found in bodily fluids function in a healthy as well as a diseased setting, potentially providing a means to accurately implement early detection and monitor disease processes.
Published Reinforcement learning: From board games to protein design
(via sciencedaily.com) Original source An AI strategy proven adept at board games like Chess and Go, reinforcement learning, has now been adapted for a powerful protein design program. The results show that reinforcement learning can do more than master board games. When trained to solve long-standing puzzles in protein science, the software excelled at creating useful molecules. In one experiment, proteins made with the new approach were found to be more effective at generating useful antibodies in mice than were previous methods. If this method is applied to the right research problems, it likely could accelerate progress in a variety of scientific fields.
Published Evolution of two contagious cancers affecting Tasmanian devils underlines unpredictability of disease threat
(via sciencedaily.com) Original source Evolution of two contagious cancers affecting Tasmanian devils underlines unpredictability of disease threat. Scientists have traced the family trees of two transmissible cancers that affect Tasmanian devils and have pinpointed mutations which may drive growth of deadly diseases.
Published Fungal genetics could help develop novel biotechnologies
(via sciencedaily.com) Original source An essential pillar of Earth's ecological system, fungi have long been used to better the lives of humans. While these organisms are still vastly understudied, a new review paper suggests that their unique genomes could be used to make progress in the biotech industry.
Published AI system can generate novel proteins that meet structural design targets
(via sciencedaily.com) Original source A new machine-learning system can generate protein designs with certain structural features, and which do not exist in nature. These proteins could be utilized to make materials that have similar mechanical properties to existing materials, like polymers, but which would have a much smaller carbon footprint.
Published Engineering the next generation of cell and gene therapies
(via sciencedaily.com) Original source Investigators are developing a novel way to treat amyotrophic lateral sclerosis (ALS) and retinitis pigmentosa using engineered stem cells that may eventually lead to personalized treatments.
Published Quantum entanglement could make accelerometers and dark matter sensors more accurate
(via sciencedaily.com) Original source The 'spooky action at a distance' that once unnerved Einstein may be on its way to being as pedestrian as the gyroscopes that currently measure acceleration in smartphones.
Published Two qudits fully entangled
(via sciencedaily.com) Original source Recently quantum computers started to work with more than just the zeros and ones we know from classical computers. Now a team demonstrates a way to efficiently create entanglement of such high-dimensional systems to enable more powerful calculations.
Published Quantum computer applied to chemistry
(via sciencedaily.com) Original source There are high expectations that quantum computers may deliver revolutionary new possibilities for simulating chemical processes. This could have a major impact on everything from the development of new pharmaceuticals to new materials. Researchers have now used a quantum computer to undertake calculations within a real-life case in chemistry.
Published Embracing variations: Physicists analyze noise in Lambda-type quantum memory
(via sciencedaily.com) Original source In the future, communications networks and computers will use information stored in objects governed by the microscopic laws of quantum mechanics. This capability can potentially underpin communication with greatly enhanced security and computers with unprecedented power. A vital component of these technologies will be memory devices capable of storing quantum information to be retrieved at will.
Published Simple addition to corn bran could boost grain's nutritional value 15-35%
(via sciencedaily.com) Original source What if, by adding a couple of cell layers inside a corn kernel, the grain could become significantly richer in essential nutrients like iron, zinc, and protein? Such an improvement could benefit people who rely on corn for a large portion of their diet, as in many parts of the global south.
Published Study links 'stuck' stem cells to hair turning gray
(via sciencedaily.com) Original source Certain stem cells have a unique ability to move between growth compartments in hair follicles, but get stuck as people age and so lose their ability to mature and maintain hair color, a new study shows.
Published Loops, flags and tension in DNA
(via sciencedaily.com) Original source Two protein complexes carry the major responsibility for the spatial organization of chromosomes in our cell nuclei. DNA tension plays a surprising role in this. Nanoscientists now publish how they have visualized this.
Published New mechanism for DNA folding
(via sciencedaily.com) Original source A hitherto unknown mechanism for DNA folding is described in a new study. The findings provide new insights into chromosomal processes that are vital to both normal development and to prevent disease.
