Do fungi breathe? That’s what listener Alice wants to know - and we’ll find out in our punniest episode yet! We visit the Fungarium - the largest and oldest collection of fungi in the world with curator Lee Davies, who describes himself as a “librarian” of mushrooms. We’ll explore how fungi live and die, and why there’s so many species left to discover. Watch out for the zombie fungi! And beware, Lindsay and Marshall don’t hold back on the “fun guy” puns!

Why do seals have whiskers? Listener Karah’s question dives into the wonderful world of whisker science. Robyn Grant, a self-described “whisker biologist” shares her discoveries of how whiskers work, from training a friendly seal named Moe to making slow-mo movies of super speedy “whisking.” (You will find no cuter field of research… but if you do, tell us about it!) Listen to learn about humans’ hidden whisker muscles and find out to rank whiskers like the pros!

How do people learn — and how can a video game help us find out? In this episode, we meet cognitive scientist Charley Wu, who built the ultimate science “mod” in Minecraft! Journey into a video game world of science to discover how and why Charley used one of the world’s most popular games to follow his curiosity about how humans learn. Featuring a “braintrust” of kid Minecraft experts to explain the game to Lindsay and Marshall, and a song inspired by The Minecraft Movie.

Why do we have snot? Do animals get stuffy noses, too? We delve into the world of thick secretions with the help of Dani Rabiaotti, zoologist and author of “Believe it or Snot: The Definitive Field Guide to Earth’s Slimy Creatures.” You’ll find out why we make so much mucus, and meet the slimiest animals on the planet. Plus, you’ll discover why scientists study slime, even though it’s super gross.

This is a rebroadcast of one of our favorite episodes from season 5, inspired by a question we recently got from our listener Harrison, who wondered why snot exists. Hopefully this answers the question for him!

Come explore “Under the Sea” to discover the chorus of fish noises with help from fish ecologist Audrey Looby.  We’ll find out how fish can be sneaky, loud, and even “slimy, grumpy cuties” (Audrey’s words) who go boop boop - and what they can tell us about life underwater. 🌊

Are ghosts real… or not? That’s what Lily wants to know. To find out, we talk to a real-life Ghostbuster and science historian Efram Sera-Shriar, who takes us on a journey back in time to when the world’s most famous scientists became ghost investigators: Sitting in on séances, inventing ghost-hunting devices, and exposing the tricks of “spirit photography.” Did you know, Thomas Edison made plans to create a phone to call ghosts?

Why are there so many axolotls in fishtanks, and so few in the wild? That’s what Maximiliano wants to know. You may have found axolotls in the lush caves of Minecraft, but in real life, they live in the lakes and canals of Xochimilco, near Mexico City. But the species is slowly disappearing from its native habitat. Axolotl veterinarian Horacio Mena takes us on a journey to Xochimilco to find out what scientists are doing to save these adorable amphibians.

This material is based upon work supported by the National Science Foundation under Grant No. 2415575.
