Brains On! Science podcast for kids

You dream every night, even if you don't remember them. But why? We'll hop on a wild ride to go inside the brain and see which parts help create these often fantastical images and storylines. We'll also learn how to take control of our dreams and how they make us more creative. Plus: a new mystery sound and a Moment of Um answers the question "How do octopuses make ink?"

Warning! This episode is all about the fascinating and gross world of doo doo.
We know you have a lot of poo questions because you’ve sent many, many of them to us. So we’re finally bringing you the poo answers! It’s a poop party!
We’ve invited scientists to tell us about weird animal feces. (It’s true! Wombats have cube-shaped poop!)
We tune into a news channel all about dookie (see the Bristol Stool Chart here: https://www.bladderandbowel.org/wp-content/uploads/2017/05/BBC002_Bristol-Stool-Chart-Jan-2016.pdf).
We hear from our favorite “poo-tuber” Taylor the Turd about how some poops are helping fight serious illnesses. (Remember Taylor? Here’s her first appearance: https://www.brainson.org/shows/2019/03/19/flush-where-does-our-poo-and-pee-go)
Plus, a sorta stinky Mystery Sound and a Moment of Um answering a question: why is pee yellow?

The flu shot changes every year. But why is the flu special, if other illnesses have much longer-lasting vaccines? This episode takes us into the world of viruses and immunity.
We released this episode about flu vaccines last year but we wanted to share it with you again since it’s flu vaccine season but also because vaccines are in the news a lot lately. Scientists are testing a bunch of vaccines for the new coronavirus right now. This episode gets into the details of how vaccines work and how they’re made.
A friendly lymphocyte fills us in on how flu shots work, and science journalist Anna Rothschild shares how vaccines started around the world. We'll hear from some virus-busting detectives to see how scientists solve the case of how to make next year’s flu shot as effective as possible. Author Maryn McKenna will stop by and drop some flu knowledge, too!

Get your ears ready for a good, thumping mystery sound, and a new Moment of Um: how do straws work?

Fair warning: Today we’re gonna get gross! We’re talking sounds, smells, and tastes that some people might find repulsive. But we're asking: why? What's the purpose of disgust? Is it something we're born knowing or do we learn to dislike things? When will entomophagy (the eating of insects) catch on everywhere? Plus: The Moment of Um answers the question "Why do worms come out when it rains?"

Bones! They’re spooky. They’re creepy. They’re utterly fascinating!
This episode we dig up the science behind skeletons. We’ll look at how our bones grow, what happens when we break a bone and why bones last so long. Plus, we’ll meet a talking skeleton who will help us bone up on bone trivia!
And we have a mystery sound to tickle your auditory ossicles and a Moment of Um that answers the question: Why does time fly when you're having fun?
We’re taking a break after this episode and will be back with new episodes on Jan. 5th. Until then, we’d love for you to go check out our sister show Smash Boom Best (smashboom.org).
We’re also going to be doing a live virtual hangout in November where you can ask Molly, Marc, Sanden and Menaka all your questions. Anything you want to ask, we’ll answer! If you want to join us, the first step is to sign up for our totally free fan club (brainson.org/fans). In November we’ll send an email out to the fan club with more details about this free, virtual hang out. So keep an eye out for that!
