Scientists at Northwestern University have discovered a genetic mutation in an isolated Amish population that helps them live longer and healthier lives, and protects them from diabetes and other age-related illnesses. A drug that mimics those effects is currently being trialled in humans, and shows promise in slowing aging, preventing diabetes and may even counteract baldness.
