A drug called rapamycin helped mice live longer - males lived about 9% longer and females lived about 14% longer when they started taking the drug in late adulthood.

Giving old mice the drug rapamycin when they're about 600 days old helps them live longer - female mice lived about 14% longer and male mice about 9% longer than mice that didn't get the drug.

A drug called rapamycin helps mice live longer, and scientists have confirmed this works in three different labs - the results show both male and female mice benefit.

Scientists gave mice a drug called rapamycin when they were middle-aged (around 270 days old) and found that both male and female mice lived longer compared to mice that didn't get the drug.

Giving mice the drug rapamycin makes them live longer, but not because it stops particular diseases. Instead, it seems to slow down the basic aging process itself.
