Study describes new way of generating insulin-producing cells
Researchers at Karolinska Institutet in Sweden show how a molecule that they have identified stimulates the formation of new insulin-producing cells in zebrafish and mammalian tissue, through a newly described mechanism for regulating protein synthes.....»»
Scientists provide explanation for exceptional Tonga tsunami
Scientists say they have identified the exact mechanism responsible for the exceptional tsunami that spread quickly across the world after the colossal eruption of the Tonga volcano earlier this year......»»
Hydrodynamic model of fish orientation in a channel flow
For over a century, scientists have sought to understand how fish orient against an incoming flow, even without visual and flow cues. In a study published in eLife, researchers explore a potential hydrodynamic mechanism of fish rheotaxis—movement a.....»»
Air lasing: A new tool for atmospheric detection
Ultrafast laser technologies provide new strategies for remote sensing of atmospheric pollutants and hazardous biochemical agents due to their unique advantages of high peak power, short pulse duration and broad spectral coverage......»»
Oldest insect resource pulses revealed by fossils from China
Resource pulses, i.e., occasional episodes of ephemeral resource superabundance, represent a fundamental mechanism by which energy, nutrients, and biomass are transported across ecotones. They are widespread in extant ecosystems; however, little is k.....»»
Probing the crucial charge carrier transfer processes and dynamics within perovskite active layers
A new publication from Opto-Electronic Science reviews the crucial charge carrier transfer processes and dynamics within perovskite active layers by means of time-resolved ultrafast laser spectroscopy......»»
Physicists demonstrate novel mechanism that can prevent light waves from spreading freely
In collaboration with the group of Professor Mordechai Segev (Technion, Israel Institute of Technology), physicists from the group of Professor Alexander Szameit (University of Rostock) have demonstrated a novel type of mechanism that can prevent lig.....»»
Secret to treating "Achilles" heel" of perovskite alternatives to silicon solar panels revealed
A team of researchers from the UK and Japan has found that the tiny defects which limit the efficiency of perovskites—cheaper alternative materials for solar cells—are also responsible for structural changes in the material that lead to degradati.....»»
Further insights into the SARS-CoV-2 spike protein glycan shield
An unprecedented wealth of information has been gathered on SARS-CoV-2 in a very short period. This information is primarily focused on the cellular entry process and mechanism of antibody recognition where mainly protein-protein interactions occur......»»
Research reveals surprising inactivation mechanism for a voltage-gated ion channel
Scientists at St. Jude Children's Research Hospital are studying voltage-gated ion channels (VGICs). Their work revealed a previously unknown mechanism of inactivation for one such channel that plays an important role in how neurons and muscles respo.....»»
Researchers detect a novel binding mechanism between small and gigantic particles
Researchers at the 5th Physical Institute of the University of Stuttgart have verified a novel binding mechanism forming a molecule between a tiny charged particle and a gigantic (in molecular terms) Rydberg atom. The scientists observed the molecule.....»»
Function follows form in plant immunity
Scientists from the Max Planck Institute for Plant Breeding Research (MPIPZ) and the University of Cologne, Germany, have discovered a novel biochemical mechanism explaining how immune proteins defend plants against invading microorganisms. Their fin.....»»
Discovering a new way by which aerosols rapidly form and grow at high altitude
Aerosol particles can form and grow in Earth's upper troposphere in an unexpected way, reports the CLOUD collaboration in a paper published today in Nature. The new mechanism may represent a major source of cloud and ice seed particles in areas of th.....»»
Arabidopsis thaliana shoots regenerate better in balmy conditions
Warm temperatures strongly enhance the regeneration of thale cress shoots, plant scientists at RIKEN have found. They have also uncovered the molecular mechanism behind this effect, which will help optimize the regeneration of plant cuttings for both.....»»
Study sheds new light on the mechanism of individual cell memory, using yeast as a model
Whi3 is a mnemon (Whi3mnem), or in other words, a protein that stores information in individual cells by forming stable super-assemblies. This memory state is then inherited by only one individual daughter cell at mitosis (individual memory). For exa.....»»
Universal mechanism to explain formation of carbon nanoparticles in interstellar and terrestrial environments
Carbon nanostructures that formed in circumstellar envelopes around carbon-rich stars may have a shared chemical origin with soot particles produced by fuel combustion. The same reaction mechanism may underpin each process, KAUST researchers have sho.....»»
Molecular mechanism of ZDHHC18-mediated palmitoylation of cGAS in innate immunity inhibition
Cyclic GMP-AMP synthase (cGAS), a double-stranded DNA (dsDNA) sensing protein, plays an important role in the strong innate immune response induced by pathogen derived nucleic acids......»»
