Although rapamycin reliably extends lifespan in a range of organisms, new research shows that it does not achieve this via the same pathways as caloric restriction [1]. Understanding how the two processes differ and interact could help researchers eventually piece together the longevity puzzle. Caloric or dietary restriction (CR) is perhaps the most robust, effective...
