Tree of Life–Lost and Found

A hamster-sized primate from Madagascar, the fat-tailed dwarf lemur is our closest genetic relative known to hibernate. They also tend to live longer than you’d expect given their size. New research reveals a potential anti-aging mechanism within their cells. (Image Credit: David Haring, Duke Lemur Center)

What lemurs can teach us about healthy aging

Discover how hibernating lemurs turn back time on a molecular level, helping scientists better understand cellular aging.

Lemon shark

Comparing the prehistoric predator to today’s great white probably resulted in an underestimation.

Sad fish swimming by microplastics

Learn about the source of airborne microplastics, which were not, for the most part, introduced into the air by the ocean, as previous studies seem to suggest.
