 Chemical engineer Beth Sattely studies the intricate chemistry of plant life. Plants are more than food, she says: They are living chemical factories churning out molecules that help plants do everything from adapting to climate change to fighting infections – or even producing valuable new cancer drugs. Lately, Sattely’s lab is working on ways to make crops more resilient to engineer more sustainable foods and environments. Some of our most exciting technologies already exist in nature, we just have to find them, Sattely tells host Russ Altman on this episode of Stanford Engineering’s The Future of Everything podcast.Have a question for Russ?
