As we age, our brains naturally atrophy, and we experience cognitive decline. New research suggests that listening to music or playing a musical instrument may improve cognitive functioning in healthy older people.

Like many highly addictive drugs, ketamine causes a rush of dopamine in the brain. But new research in mice from the University of Geneva shows ketamine also blocks the brain process that leads to neuroplasticity, habit formation and compulsion.

Scientists in Europe have discovered a molecular “zipper” mechanism that can lead to cell death in the genetic disease retinitis pigmentosa. The good news is that injecting certain proteins could slow or prevent vision impairment from the disease.

​In addition to being able to work even when it's cut in half, the liver has another trick up its sleeve: it also doubles in size on a daily basis, at least in mice. The way in which it does so could give us valuable insight into how human wake/sleep cycles could impact such a valuable organ.
