Tech Xplore / Study solves key micro-LED challenges, enabling 'reality-like' visuals for AR/VR devices
From TVs and smartwatches to rapidly emerging VR and AR devices, micro-LEDs are a next-generation display technology in which each LED—smaller than the thickness of a human hair—emits light on its own. Among the three ...
Phys.org / Immunoglobulin G's overlooked hinge turns out to be a structural control hub
The lower hinge of immunoglobulin G (IgG), an overlooked part of the antibody, acts as a structural and functional control hub, according to a study by researchers at Science Tokyo. Deleting a single amino acid in this region ...
Phys.org / Saltwater crocodiles traveled thousands of miles across the Indian Ocean, genetic study suggests
Accounts from early expeditions to the Seychelles more than 250 years ago described crocodiles as common along the coasts of the archipelago. But after the first settlers established a permanent presence in 1770, the Seychelles ...
Phys.org / Changes to cougar diets and behaviors reduce their competition with wolves in Yellowstone, study finds
A new study shows that interactions between wolves and cougars in Yellowstone National Park are driven by wolves stealing prey killed by cougars and that shifts in cougar diets to smaller prey help them avoid wolf encounters. ...
Medical Xpress / Electronic informed consent in research on rare diseases sees strong participant interest
Research on rare diagnoses and the development of precision medicine depend on patients being able to share their health data in a secure and ethical manner. The research study, published in Scientific Reports, in which a ...
Tech Xplore / 'Thermal diode' design promises to improve heat regulation, prolonging battery life
New technology from University of Houston researchers could improve the way devices manage heat, thanks to a technique that allows heat to flow in only one direction. The innovation is known as thermal rectification, and ...
Phys.org / Ancient DNA reveals 12,000-year-old case of rare genetic disease
Researchers led by the University of Vienna and Liège University Hospital Center have identified genetic variants associated with a rare inherited growth disorder in two prehistoric individuals who lived more than 12,000 ...
Medical Xpress / Should medical marijuana be less stringently regulated? A drug policy expert explains what's at stake
Medical marijuana could soon be reclassified into a medical category that includes prescription drugs like Tylenol with codeine, ketamine and anabolic steroids.
Phys.org / How brick-building bacteria react to toxic chemical in Martian soil
Bacteria that thrive on Earth may not make it in the alien lands of Mars. A potential deterrent is perchlorate, a toxic chlorine-containing chemical discovered in Martian soil during various space missions.
Phys.org / Deforestation is drying out the Amazon rainforest faster than previously thought
Deforestation is having a more devastating effect on the Amazon rainforest than earlier data suggested. While cutting down large swaths of trees destroys vital habitats, it also harms the region's ability to generate its ...
Phys.org / The New START treaty is ending. What does that mean for nuclear risk?
On February 4, the New START Treaty, the last remaining nuclear arms control agreement between the United States and Russia, is set to expire. Signed in 2010, the agreement caps deployed strategic nuclear forces at 1,550 ...
Phys.org / Restoring ecosystem function can reverse desertification in Europe's drylands
Desertification is accelerating under climate change, threatening biodiversity, food security, and human well-being across the Mediterranean Basin, southern Europe, and the Middle East. Water scarcity and land degradation ...
