Season 12 Episode 17 | 14m 35s

Our lizard friend the Gila monster probably has no idea that a chemical in its spit inspired one of the most important medical advancements of the 21st century. But this story is really about something bigger. Something deeper, beneath the surface. About why we do science in the first place. And about what kind of questions are the best ones for scientists to ask.
