Published Quantum pumping in molecular junctions
(via sciencedaily.com) Original source Researchers have developed a new theoretical modelling technique that could potentially be used in the development of switches or amplifiers in molecular electronics.
Published Zebrafish use surprising strategy to regrow spinal cord
(via sciencedaily.com) Original source A new study maps out a detailed atlas of all the cells involved in regenerating the zebrafish spinal cord. In an unexpected finding, the researchers showed that survival and adaptability of the severed neurons themselves is required for full spinal cord regeneration. Surprisingly, the study showed that stem cells capable of forming new neurons play a complementary role but don t lead the process.
Published Scientists map DNA of Lyme disease bacteria
(via sciencedaily.com) Original source Researchers have produced a genetic analysis of Lyme disease bacteria that may pave the way for improved diagnosis, treatment, and prevention of the tick-borne ailment.
Published Advancing modular quantum information processing
(via sciencedaily.com) Original source A team of physicists envisions a modular system for scaling quantum processors with a flexible way of linking qubits over long distances to enable them to work in concert to perform quantum operations. The ability to carry out such correlated or 'entangling' operations between linked qubits is the basis of the enhanced power quantum computing holds compared with current computers.
Published New way inflammation impacts cell communication
(via sciencedaily.com) Original source Researchers have made significant progress in understanding how cells communicate during inflammation.
Published Physicists throw world's smallest disco party
(via sciencedaily.com) Original source A new milestone has been set for levitated optomechanics as a group of scientists observed the Berry phase of electron spins in nano-sized diamonds levitated in vacuum.
Published Common equine painkiller disrupts assisted reproduction technique efficiency in mares
(via sciencedaily.com) Original source Researchers have discovered that phenylbutazone, a non-steroidal anti-inflammatory drug (NSAID) commonly prescribed in horses, can affect the ability of a mare's egg cells -- called 'oocytes' -- to become viable embryos, which is a crucial step in assisted reproduction in horses.
Published Exciting advance in stem cell therapy
(via sciencedaily.com) Original source A new technique for mechanically manipulating stem cells could lead to new stem cell treatments, which have yet to fulfill their therapeutic potential.
Published Surprising insight into cancer comes from unique plant species that find different solutions to evolutionary challenges
(via sciencedaily.com) Original source A study has shown that different plant species tackle the same evolutionary hurdle in different ways, and the findings may give insight into aggressive forms of cancer.
Published Rewriting the evolutionary history of critical components of the nervous system
(via sciencedaily.com) Original source A new study has rewritten the conventionally understood evolutionary history of certain ion channels -- proteins critical for electrical signaling in the nervous system. The study shows that the Shaker family of ion channels were present in microscopic single cell organisms well before the common ancestor of all animals and thus before the origin of the nervous system.
Published The mother of all motion sensors
(via sciencedaily.com) Original source Researchers have used silicon photonic microchip components to perform a quantum sensing technique called atom interferometry, an ultra-precise way of measuring acceleration. It is the latest milestone toward developing a kind of quantum compass for navigation when GPS signals are unavailable.
Published Starvation and adhesion drive formation of keratinocyte patterns in skin
(via sciencedaily.com) Original source Cell-cell adhesion-induced patterning in keratinocytes can be explained by just starvation and strong adhesion researchers find.
Published How mortal filaments' self-assemble and maintain order: Align or die
(via sciencedaily.com) Original source A previously unknown mechanism of active matter self-organization essential for bacterial cell division follows the motto 'dying to align': Misaligned filaments 'die' spontaneously to form a ring structure at the center of the dividing cell. The work could find applications in developing synthetic self-healing materials.
Published A new mechanism for shaping animal tissues
(via sciencedaily.com) Original source A key question that remains in biology and biophysics is how three-dimensional tissue shapes emerge during animal development. Research teams have now found a mechanism by which tissues can be 'programmed' to transition from a flat state to a three-dimensional shape.
Published Bacteria encode hidden genes outside their genome--do we?
(via sciencedaily.com) Original source A 'loopy' discovery in bacteria is raising fundamental questions about the makeup of our own genome -- and revealing a potential wellspring of material for new genetic therapies.
Published Researchers make breakthrough in understanding species abundance
(via sciencedaily.com) Original source The key finding was that temperature and genome size, not body size, had the greatest influence on the maximum population growth rate of the diatoms. Yet body size still mattered in colder latitudes, conserving Bermann's Rule.
Published Viral defense protein speeds up female stem cell production
(via sciencedaily.com) Original source A viral defense mechanism can be used to accelerate the creation of female stem cell lines in mice. The findings can boost efforts in medical research, drug testing, and regenerative therapies, particularly for women and individuals with two X chromosomes.
Published Do smells prime our gut to fight off infection?
(via sciencedaily.com) Original source In nematodes and humans, mitochondrial stress in the nervous system initiates a whole-body response that is most pronounced in the gut. A recent study showed that in nematodes, the odor of a pathogen triggers the nervous system to broadcast this response to the rest of the organism, prepping mitochondria in intestinal cells to fight a bacterial infection. Humans, too, may be able to sense pathogenic odors that prepare the gut for an infection.
Published X-ray imagery of vibrating diamond opens avenues for quantum sensing
(via sciencedaily.com) Original source Scientists at three research institutions capture the pulsing motion of atoms in diamond, uncovering the relationship between the diamond's strain and the behavior of the quantum information hosted within.
Published First measurement of electron- and muon-neutrino interaction rates at the highest energy ever detected from an artificial source
(via sciencedaily.com) Original source Understanding neutrino interactions is crucial for obtaining a complete picture of particle physics and the universe. To date, neutrino interaction cross sections have not been measured at high energy above some hundred gigaelectronvolts at particle colliders. Now, researchers have obtained the first direct observation of electron and muon neutrino interactions in the Teraelectronvolt range at CERN's Large Hadron Collider, using the FASER detector. This study marks a significant step for particle physics research.
