Phys.org / Mechanism for twisted growth of plant organs discovered
From morning glories spiraling up fence posts to grape vines corkscrewing through arbors, twisted growth is a problem-solving tool found throughout the plant kingdom. Roots "do the twist" all the time, skewing hard right ...
Medical Xpress / Heart-brain connection: International study reveals role of vagus nerve in keeping the heart young
The secret to a healthier and "younger" heart lies in the vagus nerve. A recent study coordinated by the Sant'Anna School of Advanced Studies in Pisa and published in Science Translational Medicine has shown that preserving ...
Medical Xpress / Antiviral trial ties valacyclovir to faster cognitive decline
New York State Psychiatric Institute and Columbia University Medical Center investigators, with co-authors across additional US centers, report greater cognitive worsening at 78 weeks with valacyclovir than with placebo among ...
Phys.org / Scientists who use AI tools are publishing more papers than ever before
Science is entering a massive publishing boom, in large part due to artificial intelligence. New research published in the journal Science has revealed that scientists who use large language models (LLMs) like ChatGPT are ...
Phys.org / Toddlers with facial tattoos: How Christianity expanded body art in Nile Valley civilizations
Ancient Nubians who lived between the 7th and 9th centuries tattooed the cheeks and foreheads of their infants and toddlers. This surprising discovery was made during a systematic survey of more than 1,000 human remains from ...
Medical Xpress / Compulsive behaviors may stem from too much (misguided) self-control
A long-held view is that compulsive behaviors involve individuals getting stuck in a "habit loop" that overrides self-control, but new research in rats from the University of Technology Sydney (UTS) suggests this might not ...
Phys.org / Controlling exciton flow in moiré superlattices: New method leverages correlated electrons
Excitons are pairs of bound negatively charged electrons and positively charged holes that form in semiconductors, enabling the transport of energy in electronic devices. These pairs of charge carriers also emerge in transition ...
Phys.org / Turning plastic waste into valuable chemicals with single-atom catalysts
The rapid accumulation of plastic waste is currently posing significant risks for both human health and the environment on Earth. A possible solution to this problem would be to recycle plastic waste, breaking it into smaller ...
Medical Xpress / Stiffer colon could signal risk of early-onset colorectal cancer
Increased stiffness of the colon, spurred by chronic inflammation, may encourage the development and progression of early-onset colorectal cancer (CRC), a study co-led by UT Southwestern Medical Center researchers suggests. ...
Medical Xpress / Stimulant ADHD medications work differently than previously thought
