Phys.org / Triassic inferno: Fires raged across Europe for millennia during past global warming
The end-Triassic mass extinction, 201 million years ago, is linked to volcanism that resulted from the break-up of Pangea and which pumped out vast amounts of CO2 into the atmosphere, causing extreme global warming of 5 to ...
Phys.org / First ever reported cryo-EM visualization of E. coli TGT structure
The enzyme tRNA-guanine transglycosylase (TGT) chemically modifies transfer RNA (tRNA) and plays a key role in how disease-causing bacteria control the production of proteins needed to cause infection. E. coli TGT is nearly ...
Phys.org / Open-source AI predicts key peptide traits before costly lab testing
Penn Engineers have developed PeptiVerse, an AI-powered platform that predicts key chemical and biological properties of peptides, strings of amino acids whose medical potential has been demonstrated by the success of GLP-1 ...
Phys.org / Satellite imagery captures the impact of large U.S. dams on river temperatures over the last decade
A team of Virginia Tech geoscientists has found a new way to examine the widespread effects of dams on river temperatures: using Landsat thermal infrared imagery to gather data on rivers across the United States. By using ...
Medical Xpress / Why 78 degrees isn't the right thermostat setting for everyone during a heat wave
Across the U.S., it's a hot summer, and electricity prices are high. Various public officials and corporate websites suggest people set their thermostats to 78°F (25.6°C), or even 81°F (27.2°C), as a way to stay relatively ...
Tech Xplore / White House accuses China's Moonshot of stealing Anthropic AI
A top White House official on Wednesday accused Chinese AI startup Moonshot AI of covertly copying Anthropic's most advanced model to build its Kimi K3.
Medical Xpress / Large national study finds differences in multiple sclerosis death rates by age, race and geography
An analysis of more than 42,000 U.S. deaths linked to multiple sclerosis (MS) found that death rates varied by age, geography, race and ethnicity, with Black patients dying younger than white patients and high blood pressure ...
Medical Xpress / AI and sleep analysis could facilitate early diagnosis of Alzheimer's
Researchers from Universidad Carlos III de Madrid (UC3M) and Hospital Universitario Severo Ochoa in Leganés, part of the public health network of the Comunidad de Madrid, have developed a methodology that uses artificial ...
Phys.org / Nanoparticles could remove harmful immune molecules from blood
The immune system, the body's defense network against infections and injuries, can sometimes become too active. In these cases, it can produce too many immune mediators, fragments of genetic material or proteins that regulate ...
Phys.org / CRISPR-Cas coordinates a layered bacterial defense network in innate immunity
All cellular life—from humans to bacteria—possesses two layers of immunity: innate and adaptive. Scientists have long understood how these two types of immunity work together in higher organisms but not in the microbial world.
Phys.org / Observations investigate the nature of a peculiar supernova
An international team of astronomers has performed follow-up observations of a peculiar Type Ia supernova designated SN 2023vjh. Results of the observational campaign, published July 9 on the preprint server arXiv, deliver ...
Phys.org / New genetic approaches raise hopes for restoring the American chestnut to its former glory
The American chestnut tree was a dominant and iconic species in many Appalachian forests until it was devastated by an introduced fungus from Asia called chestnut blight.
