Yep. Here it is. A kid-friendly episode on… poop. Camel poop. Rhino poop. Dog poop. Cat poop. Your poop. The charming and informative Dr. Rachel Santymire -- aka Dr. Poop -- has a background in animal physiology and endocrinology and is elbow deep in dung as a research director at the Lincoln Park Zoo. Dr. Poop sits down with Alie to talk turds and why some critters like to chow down on their own (or others’), the stinkiest poopers, good smelling poop, how getting curious about poop can help save a species, and why the Lincoln Park Zoo has 17 freezers full of dookie. You’re welcome.

They are numerous. They are patient. They are COMING for the United States in droves this spring: They are cicadas. *The* Cicada guy Dr. Gene Kritsky joins to chat all about the annual cicadas you may see every summer vs. the periodical ones that cycle through the states in broods of giant numbers. Learn how they survive underground for decades, what they are doing down there, and all about their lifecycle. Plus, get inspired to take a cicada safari and appreciate their songs, which can be as loud as an ambulance. By the end, you’ll want to don a bug costume and take a road trip to witness Brood XIV’s emergence this spring!
