    Could you make a real-life lightsaber?
    Dec 29 2022

    A long time ago, in a galaxy far far away… we wondered, could you ever build a real lightsaber like the ones in Star Wars? A lightsaber is a glowing sword that can cut through metal – and pretty much anything else you can think of. It’s the favorite tool of heroes like Luke Skywalker and Ahsoka Tano, as well as villains like Darth Vader. That’s just in the movies, but could we make them real? We asked mechanical engineering professor Sayan Biswas to help us find the answer.

  • Why do you lose your voice when you yell?

    Why do you lose your voice when you yell?
    Jun 6 2024

    Have you ever stayed up late talking to your friends while watching movies, or yelled for your teammates at a soccer match, or screamed at the top of your lungs walking through a haunted house? Maybe you woke up the next day with a hoarse, scratchy voice that you didn’t even recognize. In this episode, we talk to Dr. Jennifer Long, an otolaryngologist, about why we lose our voice when we yell or talk loudly.


    Do you have a Moment of Um question that’s so good it makes you want to scream? Send it to us at BrainsOn.org/contact, and we’ll help vocalize the answer.
