Phys.org / Scientists can finally answer an old question about cellular aging
After a finite number of divisions, cells simply give up. As each round of replication trims their telomeres—the protective caps at the chromosome ends—those caps eventually become too short to prevent chromosome ends ...
Phys.org / Scientists advance quantum signaling with twisted light technology
A tiny device that entangles light and electrons without super-cooling could revolutionize quantum tech in cryptography, computing, and AI.
Phys.org / Mad cow disease: A new culprit beyond prions
Recent research led by the University of Alberta challenges the belief that mad cow disease is caused only by misfolded proteins—a discovery that sheds new light on the devastating outbreak in the United Kingdom 40 years ...
Phys.org / Degraded peatlands emit nearly twice as much greenhouse gas as previously thought, study finds
For the first time, researchers have produced a detailed, high-resolution map of peatlands in the EU, showing that these areas emit twice as much greenhouse gases than previously thought. The research, led by eco-hydrologist ...
Medical Xpress / Skin-to-brain signal explains why warm hugs make us feel so good about ourselves
As winter closes in, you might start to notice your fingers and toes freezing when you go outside, or your face flushing hot when you go into a heated building. In these moments of changing temperature, we become more aware ...
Medical Xpress / How the brain prioritizes bodily signals in conscious awareness
A new study shows that visual and tactile impressions that are related to our own body are prioritized for reaching conscious awareness. This helps us understand how we develop the feeling that the body is our own—through ...
Tech Xplore / Bio-hybrid robots turn food waste into functional machines
EPFL scientists have integrated discarded crustacean shells into robotic devices, leveraging the strength and flexibility of natural materials for robotic applications.
Medical Xpress / When anger hurts: How feeling wronged can intensify chronic pain
We all know stress can worsen pain, but new research shows that anger and a sense of injustice may be even more powerful triggers.
Phys.org / Young mountain lions face barriers from roads and development across California
Previous research set off alarm bells by showing that mountain lion populations across California are more different genetically than normal for a wide-roaming predator. New findings published in Frontiers in Ecology and ...
Phys.org / New statistical tools sharpen the search for causal DNA changes in livestock
Researchers at North Carolina State University have developed a new suite of statistical methods that dramatically improves the ability to pinpoint DNA changes responsible for important traits in livestock. The work addresses ...
Phys.org / Bumble bees launch a three-stage defensive response when their nest is disturbed
Bumble bees respond to physical disturbance of their nest with a sequence of defensive behaviors that lasts up to 10 minutes, according to a study by Sajedeh Sarlak at the University of Konstanz, Germany, and colleagues.
Phys.org / Evidence of rain-driven climate on Mars found in bleached rocks scattered in Jezero crater
Rocks that stood out as light-colored dots on the reddish-orange surface of Mars now are the latest evidence that areas of the small planet may have once supported wet oases with humid climates and heavy rainfall comparable ...
