Published Atomic 'GPS' elucidates movement during ultrafast material transitions
(via sciencedaily.com) Original source Scientists have created the first-ever atomic movies showing how atoms rearrange locally within a quantum material as it transitions from an insulator to a metal. With the help of these movies, the researchers discovered a new material phase that settles a years-long scientific debate and could facilitate the design of new transitioning materials with commercial applications.
Published Lampreys possess a 'jaw-dropping' evolutionary origin
(via sciencedaily.com) Original source Lampreys are one of only two living jawless vertebrates Jaws are formed by a key stem cell population called the neural crest New research reveals the gene regulatory changes that may explain morphological differences between jawed and jawless vertebrates.
Published New drug shows promise in clearing HIV from brain
(via sciencedaily.com) Original source An experimental drug originally developed to treat cancer may help clear HIV from infected cells in the brain, according to a new study. By targeting infected cells in the brain, drug may clear virus from hidden areas that have been a major challenge in HIV treatment.
Published 'Kink state' control may provide pathway to quantum electronics
(via sciencedaily.com) Original source The key to developing quantum electronics may have a few kinks. According to researchers, that's not a bad thing when it comes to the precise control needed to fabricate and operate such devices, including advanced sensors and lasers. The researchers fabricated a switch to turn on and off the presence of kink states, which are electrical conduction pathways at the edge of semiconducting materials.
Published Quantum sensor for the atomic world
(via sciencedaily.com) Original source In a scientific breakthrough, an international research team has developed a quantum sensor capable of detecting minute magnetic fields at the atomic length scale. This pioneering work realizes a long-held dream of scientists: an MRI-like tool for quantum materials.
Published Nonreciprocal interactions go nonlinear
(via sciencedaily.com) Original source Using two optically trapped glass nanoparticles, researchers observed a novel collective Non-Hermitian and nonlinear dynamic driven by nonreciprocal interactions. This contribution expands traditional optical levitation with tweezer arrays by incorporating the so called non-conservative interactions.
Published Spin qubits go trampolining
(via sciencedaily.com) Original source Researchers have developed somersaulting spin qubits for universal quantum logic. This achievement may enable efficient control of large semiconductor qubit arrays. The research group recently published their demonstration of hopping spins and somersaulting spins.
Published Research sheds light on the role of PTPRK in tissue repair and cancer
(via sciencedaily.com) Original source New research has advanced our knowledge of multiple roles for PTPRK, a receptor tyrosine phosphatase linked to the regulation of cell-cell adhesion, growth factor signalling and tumor suppression. Through a characterization of the function of PTPRK in human cell lines and mice, the team distinguished catalytic and non-catalytic functions of PTPRK. The findings extend what is known about the signalling mechanisms involving PTPRK as a phosphatase and its role in colorectal health but also shed new light on the extent of its function via non-catalytic signalling mechanisms.
Published Under pressure: How cells respond to physical stress
(via sciencedaily.com) Original source Cell membranes play a crucial role in maintaining the integrity and functionality of cells. However, the mechanisms by which they perform these roles are not yet fully understood. Scientists have used cryo-electron microscopy to observe how lipids and proteins at the plasma membrane interact and react to mechanical stress. This work shows that, depending on conditions, small membrane regions can stabilize various lipids to trigger specific cellular responses. These discoveries confirm the existence of well-organized lipid domains and begin to reveal the role they play in cell survival.
Published Dual action antibiotic could make bacterial resistance nearly impossible
(via sciencedaily.com) Original source New drug that disrupts two cellular targets would make it much harder for bacteria to evolve resistance.
Published New rapid method for determining virus infectivity
(via sciencedaily.com) Original source A new method that can rapidly determine whether a virus is infectious or non-infectious could revolutionize the response to future pandemics, researchers report.
Published Fruit fly post-mating behavior controlled by male-derived peptide via command neurons, study finds
(via sciencedaily.com) Original source Scientists have succeeded in pinpointing the neurons within a female fruit fly's brain that respond to signals from the male during mating.
Published Exposing dengue's invasion strategies
(via sciencedaily.com) Original source Mosquito-borne viral infections once confined to tropical regions are spreading. Dengue virus infects up to 400 million people worldwide each year according to World Health Organization estimates, and no available treatments exist for this disease. Now, research uncovered surprising strategies for how dengue and hundreds of other viruses replicate in their hosts, with the potential to aid in developing novel antiviral treatments and vaccines.
Published Not everything that tastes bitter is potentially harmful: But why? Study provides an explanation
(via sciencedaily.com) Original source A bitter taste is traditionally considered a warning sign of potentially toxic substances. But not all bitter substances are harmful. For example, some peptides and free amino acids taste bitter, even though they are non-toxic, nutritious and sometimes even vital for humans. A new study now offers an explanation for this seemingly paradoxical phenomenon.
Published Transient structure in fly leg holds clue to insect shape formation
(via sciencedaily.com) Original source A little leg may reveal something big about how closely related insect species can drastically differ in body shape, according to a new study. The team imaged live cells of fruit flies in the last stages of development over several days and found a new structure that appears to help guide a section of the leg into its final shape.
Published Secrets behind viral precision
(via sciencedaily.com) Original source New research is shedding light on how viruses ensure their survival by precisely timing the release of new viruses. The discovery offers a new theoretical framework for understanding these dynamic biological phenomena.
Published Paleolithic diets are not without risks
(via sciencedaily.com) Original source High-protein diets, known as 'Paleolithic diets', are popular. Using mouse models, scientists have studied their impact. While effective in regulating weight and stabilizing diabetes, these diets are not without risks. Excess protein greatly increases ammonium production, overwhelming the liver. Excess ammonium can cause neurological disorders and, in severe cases, lead to coma. These results suggest caution when following these diets.
Published Physicists develop new theory describing the energy landscape formed when quantum particles gather together
(via sciencedaily.com) Original source An international team of physicists has proven new theorems in quantum mechanics that describe the 'energy landscapes' of collections of quantum particles. Their work addresses decades-old questions, opening up new routes to make computer simulation of materials much more accurate. This, in turn, may help scientists design a suite of materials that could revolutionize green technologies.
Published Paving the way to extremely fast, compact computer memory
(via sciencedaily.com) Original source Researchers have demonstrated that the layered multiferroic material nickel iodide (NiI2) may be the best candidate yet for devices such as magnetic computer memory that are extremely fast and compact. Specifically, they found that NiI2 has greater magnetoelectric coupling than any known material of its kind.
Published Genome recording makes living cells their own historians
(via sciencedaily.com) Original source Genomes can now be used to store information about a variety of transient biological events inside of living cells, as they happen, like a flight recorder collecting data from an aircraft. The method, called ENGRAM, aims to turn cells into their own historians. ENGRAM couples each kind of biological signal or event inside a cell to a symbolic barcode. This new strategy traces and archives the type and timing of biological signals inside the cell by inserting this information into the genome. For example, this record-keeping can track the commands that turn genes on or off.
