Mary Roach

Roach researched animal misbehaviors for her book, Fuzz. She says animals tend to ignore the rules we try to impose on them — and they often have the last laugh. Originally broadcast Sept. 14, 2021.

What happens when animals become criminals, at least in the eyes of humans….somebody has to deal with bears who menace campsites, Indian elephants that trample crops and kill farmers, and birds that flock in flight paths near airports. Science writer MARY ROACH's new book is Fuzz: When Nature Breaks the Law.

With books like Stiff and Spook, Roach has built a reputation for making unpalatable subjects entertaining. In her new book, Gulp, she tackles the human digestive system, from the mouth on down. Along the way, she gets a sedation-free colonoscopy and goes on location for a fecal transplant.
