As the host of NBC's Late Night, it's Seth Meyers' job to be funny, even when the news is catastrophic. He's satirized issues in the news, including in times of tragedy and war ever since he became an anchor on Saturday Night Live's Weekend Update in 2006. His first SNL episode was the episode following 9/11. Seth Meyers has a new children's book called I'm Not Scared, YOU'RE Scared. Also, we'll talk about the hidden world inside our bodies — from the remarkable design of our organs, to the messages contained in our body fluids, with Dr. Jonathan Reisman, author of The Unseen Body. He's a pediatrician, internist and ER physician who's worked in different cultures and in extreme climates. Justin Chang reviews the new Pixar movie, Turning Red.
