Brains On! Science podcast for kids

Stickers are everywhere. They label our groceries, cover our car bumpers, and decorate our notebooks. But how do they stick? We&rsquo;ll zoom in on a sticker to see how a special glue helps a sticker cling to a surface. Plus, we&rsquo;ll hear about stickers that can help people heal from surgeries. We&rsquo;ll also find out what kind of stickers Bob collects, and guess a new Mystery Sound. Guest: Phillip Messersmith, professor of material science and engineering at the University of California, Berkeley.

Totally Slothsome: All about sloths

Have you ever heard of Lake Natron? It&rsquo;s located in Tanzania, Africa, and, if you believe the internet, it can instantly petrify anything that touches it. Lucky for us, we have a direct line to the Hoax Hunters (aka Sanden and Marc) - they love myths, and they hate getting tricked. Along the way to saying yea or nay to this stoney phenomenon, the Hoax Hunters speak with Neovitus Sianga. Not only does he have firsthand knowledge of the lake, but he works for <a href="https://www.africanpeoplewildlife.org/">African People and Wildlife</a>, where he helps protect the environment around Lake Natron. We also have a brand new Mystery Sound&hellip; and Marc and Sanden start a cleaning service?!? Guest:&nbsp;Neovitus Sianga Want more Hoax Hunters?

Hoax Hunters: Can a lake turn animals to stone?

Skunks can stink, no doubt about it. But that stink is actually a superpower!

Brains On is coming to a city near you!

In our final look at metal, we explore how metal wires changed the world. Once humans figured out how to send little blasts of electricity through metal, we quickly developed lots of uses for this. One was a new way of communicating called the telegraph. Join Molly and co-host Ava as they team up with Dylan Thuras, co-founder of Atlas Obscura to learn how people laid hundreds of miles of wire in hopes of sending messages across oceans. Plus, the new Brains On Headquarters is having an opening ceremony, and there&rsquo;s a brand new Mystery Sound to guess!

How metal wires changed the world!

Humans have been fascinated by metal for thousands of years. But it took us a long time to master making things with metal. In this episode we go back in time to learn how Japanese swords were forged, how swings were used to make thin metal wires and why steel cables saved so many lives. Molly and co-host Ava are joined by Dylan Thuras, co-founder of Atlas Obscura for part two of this deep dive on all things metal. Plus, Marc meets some talking boxes and there&rsquo;s an all new Mystery Sound.

How mastering metal saved lives

Metal is amazing. It can be super strong like a steel beam. Or super flexible, like a copper wire. Humans have been obsessed with metals of all kinds for a very long time. This is part one a three-part look at how humans have used metal throughout history. Molly and co-host Ava are joined by Dylan Thuras, co-founder of Atlas Obscura, to look at how Earth got metal in the first place, how humans first found and used this stuff, and when we started making primitive tools with it. Plus, Marc and Sanden have some problems unpacking the new Brains On library. All that and a Mystery Sound!

How is metal made?

Most of us take listening to music or podcasts for granted. You can find them on your phone, in the car or just about anywhere you can imagine. But, have you ever wondered how those sounds were captured in the first place? To find out, Molly and Co-host Canyon shrink down and follow a sound waves as it is recorded and stored. They meet a robot who really loves to eat old school media, like cassettes and CDs. And they learn how speakers turn information into the music we hear. All that plus a new mystery sound.

How does music get recorded and stored?

We treat dogs like they're part of the family. But do they know they are a different species, or do they think they're just short, four-legged people? In this episode, canine cognition researcher Alexandra Horowitz helps us puzzle out this question. We&rsquo;ll also find out what happens (or doesn&rsquo;t) when a dog looks in the mirror. Dogs are always dozing, and we&rsquo;ll check in to see if they are dreaming too. And, we take a quick trip around the world in the language of barks. All that, plus a brand new Mystery Sound!
