Phys.org / Scientists teach helices to switch shapes
Researchers at the University of Jyväskylä have discovered a simple way to program synthetic molecules so they can form specific spiral-like structures by embedding instructions directly into their sequence. This breakthrough ...
Tech Xplore / Squashing 'fantastic bugs' hidden in AI benchmarks
After reviewing thousands of benchmarks used in AI development, a Stanford team found that 5% could have serious flaws with far-reaching ramifications.
Phys.org / Mitochondrial enzyme's atomic-level structure reveals how it processes RNA
Researchers at the Department of Cell and Molecular Biology, Karolinska Institutet have captured the first detailed molecular snapshots of human polynucleotide phosphorylase (hPNPase) in action, revealing how this essential ...
Phys.org / Warblers borrow color-related genes from evolutionary neighbors, study finds
Wood warblers, also called New World warblers, are some of the most colorful birds in North America, with more than a hundred species in the family ranging in color from yellow, orange and red to blue, green and pink. A new ...
Medical Xpress / How the cerebellum builds its connections with the rest of the brain during early development
For the first time, a team of researchers at the Institute for Neurosciences (IN), a joint center of the Spanish National Research Council (CSIC) and Miguel Hernández University of Elche (UMH), has reconstructed how the ...
Medical Xpress / Study shows why mRNA-based COVID-19 vaccines can cause myocarditis
Stanford Medicine investigators have unearthed the biological process by which mRNA-based vaccines for COVID-19 can cause heart damage in some young men and adolescents—and they've shown a possible route to reducing its ...
Phys.org / The American West's most iconic tree is disappearing
A profound unraveling is underway in the American Southwest, happening across a thousand-mile arc from Santa Fe, New Mexico, to the central Sierra. In an unprecedented calamity, the most widely distributed, most iconic tree ...
Phys.org / Hidden fuel for ocean microbes: Urea emerges as key energy source for marine ammonia oxidizers
Ammonia-oxidizing archaea (AOA) are some of the most abundant microorganisms in the ocean and play a key role in nitrogen cycling. Yet, despite their ubiquity, scientists have long puzzled over how these microbes can flourish ...
Phys.org / Roman urbanism was bad for health, new study confirms
Analysis of skeletal remains from England before and during Roman occupation confirms theories that the population's health declined under Roman occupation, but only in the urban centers, suggesting pre-Roman traditions continued ...
Medical Xpress / CAR T-cell therapy accelerates intestinal healing in aging mice
Ever notice that as you get older, some foods no longer sit with you the same? This could be due to a breakdown of the intestinal epithelium, a single layer of cells that forms the organ's lining. The intestine plays a crucial ...
Tech Xplore / Tantalum oxide addition slows lithium-ion battery capacity loss by nearly half
Skoltech researchers have developed a new method to improve the cathode, a key battery component. They proposed doping the cathode material with high-valent tantalum and discovered that adding 0.5 mole % of tantalum oxide ...
Medical Xpress / Tricking tumors into marking themselves for destruction with focused ultrasound
USC biomedical engineers have found a way to make a solid tumor paint a target on its own back in order to train the body's immune system to find and destroy it.
