The centuries-long search for a fountain of youth has led many people down regrettable holes. But maybe not this time.

A group of scientists, led by Dario Valenzano at the Max Planck Institute for Biology of Ageing, have found that older fish live longer when fed microbes from the feces of young fish. Their study hints at the role that the microbiome, a collection of microbes that live in and on the bodies of animals—including humans—may play in how we age.
