Barbs. Grunts. Bone caves. Dogs who got too close. We got porcupines, folks. Dr. Tim Bean of Cal Poly is as charming an ologist you can get, fielding questions about porcupine squeaks, stanks, cartoonish noses, and some romantic gestures that will leave you wanting to bleach your brain. We also cover counting quills, male models, flim-flam about quill removal, how to spot a porcupine in the wild, how to gently detain one for research, and so much more. An absolute instant classic.

Yes, there is an -ology for that. And yes, we’re airing this episode -– with a ton of 2025 updates -– because it’s never felt more relevant. Dr. Robert Proctor is a Stanford professor of the History of Science and co-edited the book “Agnotology: The Making & Unmaking of Ignorance,” having coined the word 30 years ago. We chat about everything from tobacco marketing, to the sugar lobby, to racial injustice, horse vision, the psychology of the Flat Earther movement, which countries have the highest rates of climate denial, empathy, how to navigate difficult conversations and why it's critical to dismantle the systems of willful ignorance, starting locally.

Do they sweat blood? Will one kill you? What are cocaine hippos? Is Moo Deng… okay? Actual real life Hippopotomologist Dr. Rebecca Lewison explains how hippos have some of the best – and worst – PR. We chat about pet hippos, subspecies, daily diets, the current state of hippo conservation, the absolute chaotic affection we have for pygmy hippos, their role as ecosystem engineers, what’s up with their nostrils, and how to keep a hippo in your pocket. Also: how to flatter your friends into planning a group vacation.
