About 1 out of 13 kids has a food allergy. Some are allergic to peanuts, others can’t eat dairy or shellfish or – you name it! So, why do some of us have food allergies and others don’t?

Join Molly and co-host Gemma as they learn all about food allergies. First, they’ll explore the immune system, the tiny army inside our bodies that fights off things that can make us sick. Turns out, these fighter cells sometimes think certain foods are a threat! Then they’ll chat with Dr. Adora Lin about why some people are allergic to certain foods and others aren’t — and visit a cafeteria to hear from kids with food allergies! Plus, a new mystery sound you won’t want to miss.

Have you ever wondered how things in space get their names? Us, too! In this week’s episode, Molly and co-host Cassie hear the story of a funky little moon with a very strange name.

It all started when Radiolab co-host Latif Nasser noticed something unusual on his son’s map of the solar system: a moon next to Venus called Zoozve. He’d never heard of Venus having a moon – and he’d definitely never heard of a moon named Zoozve. So, he called up his friend at NASA, and a wild space quest began!

Plus, Latif will share how YOU can enter a contest to name one of Earth’s quasi-moons. And of course, a new mystery sound that we’re really mooning over!

See the quasi-moon’s orbit here!

Radiolab co-host and host and executive producer of Connected: The Hidden Science of Everything, Latif Nasser.

Smash Boom Best producers Rosie duPont and Aron Woldeslassie are a little early for the BIG game. Looking to kill some time they decide to play Impression Sound. Just like the great Brains On game Mystery Sound, Impression Sound has players guessing sounds. BUT unlike Mystery Sound, Aron and Rosie will be making the sounds with their mouths -- like an impression. Hence the very appropriate name for this game: Impression Sound!

Ping! Another episode of Brains On just dropped! And it’s all about phones: how they help us, why they’re so hard to put down – and how to have a balanced relationship with them.

In this episode, Molly and co-host Linden do a deep dive on phone use. They’ll chat with an expert about whether screens are bad for us and hear from some teenagers about how they really feel about their phones! Meanwhile, Marc takes his camels Humpty and Dumpty to a phone-free picnic, and Dwayne the Brain demonstrates the powerful connection between phones and dopamine. All that, plus a stumper of a mystery sound!

We’ve been thinking about our phones a lot here at Brains On – so we started this new thing called Analog August, a month-long campaign to unplug our phones and get out in the world. If this episode inspires, we hope you and your family will join in the fun, and do your best to use your phones less! Parents can attend our virtual event about kids and phones on Thursday, August 15th from 12pm PT / 2pm CT / 3pm ET and sign up for our newsletter of ideas for phone-free adventures and tips on finding a healthy screen-life balance.
