Aging and wisdom are supposed to go together, but it turns out that a molecule that prevents one may actually play a role in the other.

Researchers have discovered a new role for the famous antiaging protein SIRT1. It not only fends off aging, but also aids in learning and memory, a new study published online July 11 in Nature shows.

Sirtuins, a family of proteins that includes SIRT1, help to regulate gene activity and have been implicated in governing metabolism and many of the biologica...
