Joining our resident science nerd Nate Evans on this episode is best-selling author and science popularizer Mary Roach, whose books have explored human cadavers, the afterlife, scientific sex, bringing readers from the edges of space to the deepest regions of the human colon. She’s here to talk about her latest, Replaceable You: Adventures in Human Anatomy, an exploration of human augmentation and body replacement, now available at your favorite book store or local library.

Listen as they discuss limb replacements, artificial genitalia, plastic surgery fads, having journalistic standards, the importance of organ donation and much more. It’s a spirited, sometimes filthy, but never frivolous chat with one of today’s most passionate promoters of scientific literacy about the resiliency of human adaptability.
