“It’s not just that we’re trying to make people live longer; we’re trying to make people live healthier. This is an exciting time for research,” says Felipe Sierra, director of the Division of Aging Biology at the National Institute on Aging.

Within them, the scientists found a treasure trove of molecules that may have played a key role in allowing early forms. Read more and download the iPad app.
