Mary Roach, Janesh Rahlan, and Amy Millan

Popular science writer Mary Roach dives into lab-grown organs, historical nose jobs, and unlikely hair transplants, as covered in her latest book Replaceable You: Adventures in Human Anatomy; stand-up comedian Janesh Rahlan riffs on learning Spanish as an Indian American growing up in Texas; and singer-songwriter Amy Millan (of the indie group Stars) recites her teenage monologue from Degrassi Junior High, before performing a track from her new solo album I Went to Find You.
