Phys.org / Scientists capture first molecular-level images of water reorganization during a reaction crucial for life
Some of nature's most important chemical reactions rely on the coupled movement of negatively and positively charged particles. These processes play central roles in photosynthesis, catalysis and biological energy conversion ...
Phys.org / Low temperature graphene growth opens a route to sustainable resource recycling
Graphene is an exceptionally useful material for creating batteries, catalysts and electronic devices. Yet producing graphene typically requires temperatures as high as 900°C (1,652°F), limiting energy efficiency and making ...
Medical Xpress / Nearly one in five Medicaid-eligible adults may miss new 80-hour work rule
A new study found that nearly 20% of eligible adults in Medicaid expansion states are in danger of not meeting the minimum work hours that will be required nationwide beginning Jan. 1. Women, unmarried people, white individuals ...
Tech Xplore / Magnetic memory could make edge AI faster while reducing energy use
Texas engineers teamed up with the world's largest semiconductor foundry to fabricate and test an emerging memory technology that could help meet the increasing energy demand of artificial intelligence.
Medical Xpress / People with atrial fibrillation at intermediate risk of stroke benefit from oral anticoagulants, clinical trial finds
Oral anticoagulant therapy lowered the risk of adverse clinical events compared with no anticoagulation in patients with atrial fibrillation at intermediate stroke risk, according to results from the SINGLE-AF trial presented ...
Tech Xplore / Shared-memory AI system lets microscope components coordinate in real time
Arco Bast studies how neurons communicate. Earlier this year, the Janelia postdoc encountered a more mechanical version of the same problem: The components of his custom microscope could not easily communicate with one another.
Tech Xplore / Two ultrathin films turn low-grade heat into cooling without an electric motor
Refrigerators, air-conditioning systems and data centers consume enormous amounts of electricity, and cooling demand is constantly rising. A research team from the Karlsruhe Institute of Technology (KIT) and the University ...
Medical Xpress / Even symptom-free IBD patients show gut cells primed for damage, study finds
Researchers have uncovered early molecular warning signs of inflammatory bowel disease, revealing the condition can begin before symptoms appear and continue silently even when patients appear well. The WEHI-led study found ...
Phys.org / Many cities buried urban streams. Here's how to bring them back
As many cities developed, streams that once flowed on the surface were buried underground to make way for growing infrastructure. However, as heavier rainfall, extreme weather and aging infrastructure place growing pressure ...
Phys.org / Joro spiders eat wider range of insects than Georgia's native orb weavers
When Joro spiders first arrived stateside more than a decade ago, scientists worried the massive black-and-yellow spiders would gorge themselves on the same bugs as native spiders (or even the native spiders themselves). ...
Phys.org / Breathable smart sensor developed for real-time hazardous gas detection on masks
A research team led by Sungwon Lee, a professor in the Department of Physics and Chemistry at DGIST, developed a hierarchical nano-on-nano structure by directly growing graphene nanowalls (GNWs) on polymer nanofibers and ...
Phys.org / Motorboat noise stunts growth and impairs predator escape in reef fish, study shows
Coral reef fish that are exposed to motorboat noise grow up smaller and less able to dodge predators, new research shows. Scientists played either boat noise or natural reef sounds to a species from the Great Barrier Reef ...
