Exercise in a Bottle

Scientists have discovered an enzyme in the liver that increases with exercise. Enzymes are protein molecules inside living organisms that speed up chemical reactions, like digesting food or healing wounds. Research suggests that this particular enzyme may help the brain grow and function better. Its discovery could one day lead to a medicine that helps people benefit from the enzyme’s brain boosting impact, even without exercise. Listen to hear about the research scientists conducted and learn about the promise and the limits of their discovery.
