Excuse me, why do you have teeth? How did they get in your mouth and where did they come from? Let’s ask researcher, tooth enthusiast, and Paleohistologist Dr. Yara Haridy. She opened up the archives at Chicago’s Field Museum to chat about ancient skulls, drawers of bones, and the evidence that changed how we think about chompers. Drop your jaws as we discuss the origins of teeth, why yours hurt, the long-debated rumors of extinct species, how particle accelerators and paleontology worlds collide, what tools fossil pickers rely on, teeny tiny mysteries, why you should hug a tree before it kills you, and why a catfish might become your overlord.

Gassy veils! Orange sunlight! Alien life? It’s the sole goddess of our solar system: Venus. And to tour us through her beauty is the charming and enthusiastic planetary geologist and Venusian expert Dr. Vickie Hansen, a Senior Scientist at the Planetary Science Institute. In what is sure to become an instant classic, Vickie will delight you with tales of space probes past and future, dazzling terrain, myths, melting machinery, “noodle data,” analogues to Earth, tectonic misconceptions, and reactions to self-help books that capitalize on our solar geography. Also: what does Venus smell like?
