At the University of California, Berkeley, and in ponds around the world, professor Tyrone Hayes studies frogs and other amphibians. He's become an active critic of the farm chemical atrazine, which he's found to interfere with the development of amphibians' endocrine systems.

Tyrone Hayes’ TED Talk
Tyrone Hayes, Penelope Jagessar Chaffer
The toxic baby
17 minutes 31 secondsFilmmaker Penelope Jagessar Chaffer was curious about the chemicals she was exposed to while pregnant: Could they affect her unborn child? So she asked scientist Tyrone Hayes to brief her on one he studied closely: atrazine, a herbicide used on corn. (Hayes, an expert on amphibians, is a critic of atrazine, which displays a disturbing effect on frog development.) Onstage together at TEDWomen, Hayes and Chaffer tell their story.Posted Feb 2012
