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 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 rapamycin in their food when they're about 60 in human years helps them live longer - males lived 13% longer and females 9% longer on average.

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.

Scientists found that a drug called rapamycin helps mice live longer, but it works better in female mice (14% longer) than in male mice (9% longer). This suggests the drug might affect males and females differently.
