Rapamycin molecule
Rapamycin prolonged the life of mice in recent tests

Easter Island is still yielding new mysteries for scientists. Rapamycin, a chemical discovered in the soil of the island, increased the lifespan of mice up to 38% in recent tests.

Rapamycin, also known as sirolimus, is already being used as a powerful immune response suppressant, helping prevent rejection of transplanted organs. The new finding was particularly surprising, since the mice given the drug were already nearing the end of their life.

A long road of study lies ahead to determine rapamycin's effect on human longevity, if any, and doctors are already warning would-be Ponce de Leon not to try using the drug, given its potent immune-suppressing effects.
