An ancient Chinese exercise routine may be just as powerful as a daily brisk walk for lowering blood pressure -- without equipment, gyms, or intense workouts. In a major clinical trial, adults with stage 1 hypertension who practiced baduanjin, a ...

A team at the University of Hong Kong has developed a new "super steel" that can survive the harsh conditions needed to make green hydrogen from seawater. The material uses an unexpected double-protection mechanism that resists corrosion far better . ...

Scientists at the University of Rochester pulled off a remarkable experiment: they transferred a longevity-related gene from the famously long-lived naked mole rat into mice, and the mice ended up healthier and lived longer. The special gene boosts . ...

Scientists have uncovered a striking brain difference linked to psychopathy: people with psychopathic traits were found to have a striatum -- a brain region tied to reward, motivation, and decision-making -- that was about 10% larger on average than ...

Scientists have uncovered a hidden "stop-scratching" signal in the nervous system that tells your brain when enough scratching is enough. The discovery centers on a molecule called TRPV4, which acts like part of an internal braking system for itch .. ...

Scientists have uncovered a hidden Antarctic threat that could accelerate global sea level rise far faster than expected. Deep beneath floating ice shelves, long channels carved into the ice appear to trap warmer ocean water, dramatically speeding up ...

Rebooting the gut microbiome with bacteria from youth may help stop aging-related liver damage and even prevent liver cancer, according to new research in mice. Older mice that received their own preserved youthful microbiome showed less inflammation ...
