Bacteria are everywhere. At the top of Mount Everest. At the bottom of the Pacific Ocean. There are millions on your hands and TRILLIONS in your gut! So what happens when a truck rolls over bacteria on the road? Do they get squished? We asked microbiology professor Daniel Bond to help us find the answer.


Got a crushing question? Send it to us at BrainsOn.org/contact, and we’ll keep on truckin’ til we find an answer!

See Smash Boom Best LIVE in Princeton, NJ!


Join us at the McCarter Theatre for a live, in-person version of Smash Boom Best, an award winning podcast for kids and families! Each live show takes two cool things, smashes them together and lets the audience decide which is best. Host Molly Bloom moderates a debate between two performers who make their case using facts fueled by jokes, physical comedy, and the occasional song and dance. At the end, the audience votes for the winner and crowns the Smash Boom Best – all while learning how to defend their own opinions and make the strongest arguments for their case. 


While we are in town, we are throwing a Smash Boom Spectacular Party right after the live show and YOU are invited! This won't be just any party. You will get to meet host Molly Bloom and our debaters. They'll be playing games with you, singing songs, answering your questions, and posing for photos. Plus, you'll get to take home an awesome, one-of-a kind Smash Boom Best goodie bag. You can gain access to this SBSP (Smash Boom Spectacular Party) by purchasing a VIP ticket* when you make your purchase.  See you there!

We’re back! Brains On Universe has a new headquarters

We're moving the Brains On Universe Headquarters, and that means we have to stop putting out new episodes until we get settled. We know: not cool. But, our new home is going to be bigger and better and the absolute BEST. We can't wait until it's ready for you to visit.


In the meantime, we still have some live shows planned this fall. Brains On Live will be in Dallas, TX on September 13. And Smash Boom Best will bring the debate heat to Princeton, NJ on October 26. Head over to brainson.org/events to get tickets. We can't wait to high five you all in person!


And, if you want to be the first to hear about our shiny, new home, sign up for our newsletter. There will be six more bathrooms, 10 more water slides and, we're finally going to fix the doorbell! Also, if you have any questions or want to reach out to us, you can still head to brainson.org/contact to get in touch.

A big update about Moment of Um and the Brains On Universe

They come in cool colors, catch popcorn kernels and sometimes even have spacers - it’s braces! Ever wondered how braces magically straighten teeth? We asked Dr. ArNelle Wright - a real life dentist! - to help us break down the science of these tiny metal wonders.


Bracing for a tough question? Send it to us at BrainsOn.org/contact, and we’ll help uncover the tooth.
