Brains On! Science podcast for kids

If you translate “Hello! How are you?” to binary code, it looks like this: 01001000 01100101 01101100 01101100 01101111 00100001 00100000 01001000 01101111 01110111 00100000 01100001 01110010 01100101 00100000 01111001 01101111 01110101 00111111 This episode takes a look at how computers can do so much with such tiny parts. But computers weren't always small -- so we take a look at where computers came from. We visit Ada Lovelace, whose love of math and weaving paved the way for modern-day computers. And we hear about the material that let computers shrink from the size of a room to something that fits in our pockets. There’s also a visit from a yak and a ram, but you’re just going to have to listen to find out why.All that plus a new Mystery Sound and Moment of Um that answers the question: what is the flavor of root beer?This episode is sponsored by Mathnasium (Mathnasium.com) and Sun Basket (sunbasket.com promo code: brains on)

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?"This episode was sponsored by: Mathnasium (mathnasium.com)Sakara (sakara.com/brainson)Indeed (indeed.com/brainson)

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.

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?Today’s episode is sponsored by: Mathnasium: (mathnasium.com) and Sun Basket (sunbasket.com/brainson - promo code: brains on)

Screens are everywhere these days! We’re taking a look at why smartphones are so addictive, and how our devices affect us. Our co-hosts took on a bold challenge for this episode: they went a week without phones or tablets. We’ll hear how their experiment went, then Sanden will fill us in on the brain chemical that trains us to love our screens. We'll also learn why the predictability of messages and alerts on smartphones makes them extra hard to put down. Plus, we’ll get a few tips from Catherine Price, the author of How to Break Up With Your Phone. And! A our Moment of Um answers: why are bruises blue, and how do we get them?

20 years ago, we pictured dinosaurs as green, scaly animals. But times have changed! Now, we know some dinosaurs had feathers. And who knows — maybe some even had stripes.This episode looks at how we figure out what color dinosaurs might’ve been. We talk to Jingmai O’Connor, who studies fossil reptiles, about finding color pigment in fossils. And paleoartist Emily Willoughby talks to a “museum” about how her dino-depictions have changed over the years. Our co-host, Elyana, also brought us this important question: If dinosaurs evolved from birds and birds don’t fart, did dinosaurs fart? Wha-wha-what!?! Look no further than this episode for an extensive investigation.Remember to keep your ears open for the brand new Mystery Sound. And break out your kilns, because today’s Moment of Um answers this question: How do you make clay for pottery?There’s so much dino-tastic information that we decided to make a second dinosaur episode. So if you haven’t had enough (and who has?), make sure to check out next week’s show about what dinosaurs might have sounded like.This episode is sponsored by:Mathnasium (Mathnasium.com)KiwiCo (kiwico.com checkout code: BRAINSON)

In this episode, we're using our zoom ray to zoom way in and answer your questions about the COVID vaccine. What's in the COVID vaccine? How does it work? And how do they make it?
