Phys.org / 'Amazing moths': Study pinpoints insect habitat that draws grizzlies to glacier peaks
When grizzly bears clamber onto the talus slopes high in Glacier National Park, they're searching for an abundant, fatty meal: army cutworm moths. The inch-long (2.5-centimeter-long) moths hatch on the Great Plains and fly ...
Medical Xpress / Night owls eat later, choose less nutritious food, carry more belly fat and show higher metabolic risk
For generations, early to bed and early to rise was seen as the blueprint for a healthy life, and any departure from it was often considered unhealthy. Scientists, however, have discovered that whether someone is an early ...
Phys.org / What does it mean to be 'quantum?' A physicist explains the basics behind Einstein's spooky actions at a distance
Imagine shining a flashlight across a dark room. You can predict exactly what the light will do: travel in a straight line from one point to another. That seems obvious because, in the world we see around us, light appears ...
Phys.org / Europe's last pagan state was already diverse: Medieval Vilnius drew migrants from Christian lands
Lithuania was famously the final pagan state in Europe. While the rest of the continent converted to Christianity, Lithuania remained officially pagan until Catholicism was adopted in AD 1387. Despite this, the extent to ...
Tech Xplore / New catalyst could enable safer electrolyzers for clean hydrogen production
Hydrogen could serve as a clean alternative to fossil fuels because, when used as a fuel, it produces water vapor instead of carbon dioxide (CO2). This cleaner fuel has proved particularly promising for the creation of so-called ...
Phys.org / Study reveals Hawaiian hotspot is getting hotter
Contrary to conventional geological thinking, the Hawaiian mantle plume has gotten hotter by about 250°C (480°F) over the past 47 million years. This discovery, led by Earth scientists at the University of Hawai'i at Mānoa, ...
Phys.org / How supermassive black holes feed themselves
Astronomers are closer to solving the mystery of how supermassive black holes feed themselves thanks to new images from the James Webb Space Telescope, or JWST. The images provide the clearest view ever seen of gaseous filaments ...
Phys.org / 'Uncanny valley' effect observed in macaques through 3D animated monkey avatars
A new tool that allows researchers to create realistic full-body animations of monkeys has provided the first evidence that nonhuman primates experience the "uncanny valley" phenomenon for body avatars, according to a study ...
Medical Xpress / Study finds smokers are unlikely to smoke more when switching to low-nicotine cigarettes
People who switch to cigarettes with dramatically reduced nicotine levels are unlikely to smoke more cigarettes or inhale more smoke to compensate for the lower nicotine content, according to a new study led by researchers ...
Phys.org / Researchers define new frontier in quantum materials
Researchers at City College of New York physicist Vinod M. Menon's Laboratory for Nano and Micro Photonics (LaNMP) have outlined an emerging frontier in quantum materials: atomically thin systems in which light, magnetism ...
Medical Xpress / Blood-based test can predict risk of developing symptoms of Alzheimer's up to a decade early
A blood test for the biomarker phosphorylated tau 217 (p-tau217) recently received federal clearance, but questions have emerged about the extent to which such tests can accurately predict whether a cognitively healthy individual ...
Phys.org / Self‑building molecular rings bring next‑generation drug delivery and smart materials closer
Rotaxanes are dumbbell-shaped mechanically interlocked molecules in which one or more ring-shaped molecules are threaded through a linear segment, known as the axle. To keep the ring from sliding off, two bulky groups, sometimes ...
