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 .. ...

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 ...

Researchers have developed a stem cell-based model of the human intestine that may transform how new IBD treatments are discovered. After testing thousands of compounds, they identified glycyrrhizin -- a natural substance found in black licorice -- . ...

A new study shows that listening to your own favorite workout music can dramatically boost endurance. Cyclists exercising with self-selected songs lasted nearly 20% longer than when riding in silence, yet they didn't feel more exhausted at the end. . ...

Scientists studying axolotls, zebrafish, and mice have uncovered a shared set of genes that may one day help humans regrow lost limbs. By identifying powerful "SP genes" involved in regeneration, researchers discovered that disabling these genes ...

Scientists have uncovered a surprising secret hidden inside fat cells that could reshape how we think about obesity and metabolic disease. A protein called HSL, long believed to simply release stored fat when the body needs energy, turns out to have ...

A common constipation drug may have unexpectedly unlocked a new way to slow chronic kidney disease -- a condition that affects millions and often leads to dialysis. In a clinical trial involving 150 patients, researchers found that lubiprostone, a .. ...

Scientists have uncovered a surprising way to influence the bacteria living in our mouths -- not by killing them, but by interrupting how they "talk" to each other. Researchers found that dental plaque bacteria use chemical signals to coordinate ...
