Like bread and cheese? Thank fungus!

Picnics wouldn’t be picnics without fungus. Bread, cheese and salami all incorporate our fungal friends!


That fuzzy sandwich in your fridge? Yeah, don't eat that kind of fungus. But the mushrooms in your stir fry? Or the yeast in your bread? Or the rind on your brie? Or the miso in your soup? All of those delicious foods are possible thanks to fungus!

In this episode, we'll learn about how our ancestors first figured it out some mushrooms were safe to eat, we'll learn about the microbes that make cheese possible, and we'll meet some fungal chefs who are key to cooking up some of our favorite foods. Plus a brand new mystery sound and a Moment of Um that answers the question: "How does rubbing two sticks together make fire?"

Is mold alive? A look at fascinating fungus

Molds and fungi have been responsible for everything from medicines to that mystery that’s been in your fridge for too long. This episode looks at how the kingdom of fungus thrives.


Fungus deserves a party because it’s everywhere and super important to life on this planet. The kingdom of fungus includes mushrooms and molds, but also yeasts, like the kinds that help make bread. So today, we’re embracing the ick, we’re snuggling up to the slimy, we’re making friends with mold and mushrooms… It’s a full on Fung-o-Rama! We'll learn about a day in the life of mold, a fungus that turns ants into zombies, and how fungi will help us in the fight against climate change. All that, plus a brand new mystery sound and a Moment of Um that answers the question: "How does air fry?"

Is time travel possible?

Who hasn’t dreamed of going to the past or taking a peek into the future? This episode takes a look at the ins and outs of time travel. 


Will we ever get to rewind time, or fast forward through it? Sanden stops by to tell us all about how time works. He also has a couple ideas about how we might make time travel a reality! But one tricky thing about time travel is that it’s full of paradoxes — so we look into those, too. And science fiction expert Lisa Yaszek swings by to tell us just how long humans have been thinking about time travel (hint: a really long time).Listen closely for the mystery sound, and the moment of um: how do clothes get dirty even though you can’t see it?
