Medical Xpress / Oxytocin reverses anxiety-like behavior after three months of isolation in mice
Periods of prolonged social isolation have long been associated with difficult emotions and, in some cases, with the emergence of psychiatric symptoms, such as depression, anxiety, and difficulties connecting with others. ...
Phys.org / Source or sink? Trees with heart rot disease emit more methane, upending forest carbon models
Throughout their lifetimes, healthy forests produce more oxygen than they use, while taking in greenhouse gases via plants and soils. This ecosystem-wide service, called carbon sequestration, regulates global climate and ...
Phys.org / NASA moves its Artemis II moon rocket off the launch pad for more repairs
NASA moved its grounded Artemis moon rocket from the launch pad back to its hangar Wednesday for more repairs.
Medical Xpress / Did you hear about the lab-made ear?
In laboratory experiments, researchers have produced ear cartilage that remains form-stable in animal models. Only one element is missing to make the tissue as elastic as a natural ear.
Medical Xpress / Engineered immune therapy could help fight brain aging
Researchers with the Knight Initiative for Brain Resilience have modified a well-known immune protein to spark the growth of new neurons, ease brain inflammation, and improve cognition in old mice. The findings, published ...
Tech Xplore / Researchers expose critical security vulnerability in autonomous drones
University of California, Irvine computer scientists have discovered a critical security vulnerability in autonomous target-tracking drones that could have far-reaching implications for public safety, border security and ...
Phys.org / Turning high-emissions waste into fertilizer: Catalyst boosts urea production by coupling CO₂ with nitrogen pollutants
UNSW engineers have tackled a longstanding problem at the heart of global agriculture: how to make urea for fertilizer without the intensity of emissions associated with fossil-fuel-powered factories. The solution is outlined ...
Phys.org / Between the Pampa and Patagonia: New clues about how ancient hunter-gatherers fed themselves
An archaeological study reveals how ancient hunter-gatherer groups lived—and survived—more than a thousand years ago in the transition zone between the Pampas and Patagonia in Argentina. The research, carried out by Martínez ...
Medical Xpress / Meningococcal B vaccination does not reduce gonorrhea, trial results show
Contrary to existing evidence from observational studies, the meningococcal B vaccine (4CMenB) has no effect on preventing the acquisition of gonorrhea, according to the results of the world's largest randomized control trial ...
Tech Xplore / AI model edits can leak sensitive data via update 'fingerprints'
Artificial intelligence (AI) systems are now widely used by millions of people worldwide, as tools to source information or tackle specific tasks more rapidly and efficiently. Today, some of the most used are large language ...
Phys.org / Scientists deliver new molecule for getting DNA into cells
Researchers from Tokyo Metropolitan University have created a new molecule which carries DNA into biological cells, to treat or vaccinate against illnesses. Many existing options rely on molecules with a strong positive charge, ...
Medical Xpress / Medicare Advantage and Medicare–Medicaid eligible patients less likely to use highly rated stroke rehabilitation
Stroke patients with Medicare Advantage health insurance plans are less likely to be discharged to highly rated post-acute care than those covered by traditional Medicare, according to a new study co-led by researchers at ...
