Have you heard of legendary creatures like Bigfoot, Yeti or the Loch Ness Monster? Maybe you’re on the lookout for them. Maybe you’re scared of them. Maybe you don’t believe in them at all! These creatures are sometimes called cryptids–hidden animals whose existence has never been proven. We’ve gotten a lot of questions about these mysterious and mostly made-up figures. So in this episode, we talk with cryptid expert (and skeptic) Daniel Loxton, co-author of “Abominable Science: Origins of the Yeti, Nessie, and Other Famous Cryptids.” We talk about Bigfoot, Yeti, Nessie, Champ (our local lake monster here in Vermont!), mermaids and more! After listening to this episode, you decide: are cryptids fact, fiction, or something in between?

As kids, you are constantly growing. You may not be able to feel yourself growing day to day, but if you’ve ever had achy legs at the end of a long day and been told, “Those are just growing pains,” it certainly SEEMS like you can feel yourself growing! In this episode we get answers to all kinds of questions about growing. Dr. Zurisadai Gonzalez Castillo, a pediatric neurologist at the University of Texas Southwestern Medical Center, helps us understand: how tall can people grow? How do bones grow? Why do our nails and hair keep growing–and is it true our noses and ears never stop growing either?

What are eels? And why are some eels electric? We head to Poughkeepsie, New York to learn about eels with Chris Bowser, Hudson River estuary educator with the New York Department of Environmental Conservation. Plus we learn about electric eels. Electric eels have captured the imagination of many people, but they’re not actually considered eels by the scientific community. They’re a type of knife fish, more closely related to catfish and carp. But they are electric! So we’ll tackle why they’re electric and how they create electricity. David de Santana, of the Smithsonian Museum of Natural History, tells us what it’s like to study electric eels in the Amazon.
