Phys.org / Scientists uncover environmental cues behind black bear hibernation
New research from Virginia Tech scientists in the College of Natural Resources and Environment provides fresh insight into how environmental conditions influence black bear hibernation, with implications for wildlife management ...
Phys.org / Stellar eruptions in the laboratory: First experimental evidence for their suppression in strong magnetic fields
An international team of astrophysicists and plasma physicists has provided the first experimental evidence that strong magnetic fields surrounding active stars can completely suppress coronal mass ejections. This offers ...
Medical Xpress / Can COVID-19 change how we breathe during sleep?
COVID-19 can leave behind fatigue, breathing difficulties and neurological symptoms that persist long after the initial infection. Because these effects can also disturb sleep, researchers have questioned whether COVID-19 ...
Medical Xpress / Why memories get fuzzier with age—and what replaces them
Research from the University of East Anglia shows how our memories change with age and why specific details associated with past events can fade over time. The new study reveals that as people age, they not only remember ...
Phys.org / Lab-grown brain models gain a sense of place
The human brain is often described as one of the most complex structures in biology, and much of its power comes from how it's organized. Its outer layer, the cerebral cortex, is not one uniform sheet. As the brain develops, ...
Tech Xplore / Nonmetallic metasurfaces offer a new way to block radiant heat
Researchers at the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC) and Honeywell Aerospace have developed a new way to reduce the transfer of radiant heat between closely spaced bodies by using thin, ...
Phys.org / Stellar spin may explain why repeated black hole flares grow dimmer
At the center of most galaxies lies a supermassive black hole, with a mass millions to billions of times that of our sun and some of the most extreme gravity in the universe.
Medical Xpress / Self-driving cars might not be safe for everyone, study says
You might want to steer clear of self-driving vehicles if you have a history of head injuries, a new study warns. Hockey players who'd suffered repeated concussions were slower to respond when a self-driving car faced a complex ...
Medical Xpress / Tutorial unites optical brain imaging tools in a single Python framework
Functional near-infrared spectroscopy (fNIRS) measures brain activity optically based on changes in cortical blood flow. Unlike magnetic resonance imaging, the technique is wearable, so it can be used during movement and ...
Phys.org / Shark DNA could hold answers to how we age
Age isn't just a number for one of the ocean's top apex predators. It's a mystery University of Georgia researchers are solving. A new UGA study has determined how to estimate the age of sharks by analyzing changes to individual ...
Phys.org / 'Rainbow-on-a-chip' could help unlock 6G networks and precision timing for quantum technologies
Loughborough University physicists and an international team have demonstrated that a grain-of-rice-sized microchip can be used to produce a spectrum of precisely spaced frequencies of light, which is then converted into ...
Phys.org / UK forecasts 'biggest' El Nino will smash records, spark hottest year
This year's El Niño weather pattern will be the biggest in more than a century and could make 2027 the hottest year globally, Britain's national weather agency predicted Friday.
