Biologist Lauren O’Connell studies poisonous frogs, but not just the toxins that make them dangerous. She also studies the neuroscience of their complex parenting. She’s learned that tadpoles recognize their mothers by smell and do a “begging dance” when hungry, and that the frogs produce a protein that protects them from their own poisonous chemistry. That protein could help treat overdoses in humans, O’Connell tells host Russ Altman on this episode of Stanford Engineering’s The Future of Everything podcast.
