Phys.org / G protein simulations reveal how a critical signaling step works inside cells
UNC researchers discovered how a key step in cell signaling works by showing exactly how G proteins detach from receptors that many common medicines target.
Phys.org / Reed leafhopper's diverse microbes fuel its rise as a major crop pest
The reed leafhopper (Pentastiridius leporinus) was originally a specialist, limited exclusively to reed grass as a food source. Within a few years, however, it developed into a dangerous pest that attacks not only reed grass ...
Phys.org / Scientists develop CRISPR PRO-liveFISH for live-cell genome imaging
Although existing CRISPR-Cas-based imaging methods can target endogenous genomic sequences, their applications are limited by system complexity and sensitivity, particularly when imaging non-repetitive loci, performing multi-locus ...
Medical Xpress / How COVID-19 variants outsmart the immune system
Researchers at the Icahn School of Medicine at Mount Sinai and collaborators have created the most comprehensive map to date showing how antibodies attach to the SARS-CoV-2 virus, which causes COVID-19, and how viral mutations ...
Phys.org / Earth's crust under stress: Researchers decipher energy release during earthquakes
Why do some earthquakes release more energy than others? A research team led by Prof. Dr. Armin Dielforder from the University of Greifswald has managed to demonstrate a clear physical connection between the energy released ...
Medical Xpress / Reducing inflammation may protect against early age-related macular degeneration-like vision loss
University of Minnesota Medical School researchers have shown that reducing chronic inflammation can significantly protect against age-related macular degeneration (AMD)-like pathology in preclinical models. The findings ...
Medical Xpress / Heat exposure during pregnancy alters amino acids and vitamins linked to preterm birth
An Emory University study, published Friday by Science Advances, provides the first evidence that exposure to higher temperatures during pregnancy is linked to specific biological changes in mothers that are also associated ...
Phys.org / Machine learning model sharpens snowfall forecasts for the Mountain West
The varied topography of the Western United States—a patchwork of valleys and mountains, basins and plateaus—results in minutely localized weather. Accordingly, snowfall forecasts for the mountain West often suffer from ...
Phys.org / Choking during sex is common among young adults, but the risks are poorly understood
Choking during sex has moved from the margins to the mainstream for many young adults, but the risks have not changed. New research shows how common the practice has become, and how confused many people are about what makes ...
Medical Xpress / Macrophages can act like neurons for faster muscle injury repair, study finds
At the cellular level, the mechanics of how muscle tissue repair occurs gets complicated. There are significant differences between, say, tearing a muscle in a sports injury versus muscle tissue wasting away from diseases ...
Phys.org / Physicists explore optical launch of hypersound pulses in halide perovskites
A German-French team of physicists from TU Dortmund University, University of Würzburg, and Le Mans Université has succeeded in launching shear hypersound pulses with exceptionally large amplitudes in metal halide perovskites ...
Phys.org / When the air gets dry, cockroaches cuddle: Study reveals survival strategy
When conditions get too dry, Madagascar hissing cockroaches like to "cuddle." Under certain conditions, the large insects gather in groups, with many participants in physical contact with one another. According to recent ...
