Phys.org / Mercury's crust points to deeper, hotter volcanic origins than expected
The evolutionary histories of Earth and Mercury differ fundamentally. The smallest planet, closest to the sun, likely began cooling early on, much like a setting pudding: As early as about 1 billion years after its formation, ...
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 / New transistor brings high voltage to microchip scale
Inside every electronic device, the flow of electricity is controlled by a switch called a transistor. For decades, these switches were made from silicon. More recently, engineers have turned to a material called gallium ...
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.
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 ...
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 / How AI‑powered policing is endangering the public's trust in police
Since the release of ChatGPT in 2022, artificial intelligence (AI) has dominated the cultural landscape. Uptake across various sectors, including law enforcement, quickly followed, usually with minimal foresight and little ...
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.
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 ...
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 / Eagles known as hunting specialists reveal an unexpected taste for goat
Eagles are symbols of hunting prowess. Known as top predators wherever they live, they are often assumed to kill as their primary mode of obtaining food. However, a new study published in the Journal of Raptor Research reports ...
