Is everything inflammation?
To hear some people tell it — especially people on TikTok — inflammation is the root of all disease. It's... not that simple. But inflammation does have a lot to teach us about why modern life can make us feel so bad, and even what we might be able to do about it.

So he called up host Noam Hassenfeld to ask him a question he couldn't stop thinking about: How do you make something that sounds like nothing?Host: Rob Rosenthal, host of Sound School PodcastGuest: Noam Hassenfeld

Why did we go back to the moon?

Casey gets his voice back
Casey Harrell is a goofy, lighthearted chatterbox whose love for language helped him become an accomplished environmental activist. In 2020, he was diagnosed with Amyotrophic lateral sclerosis (ALS) and slowly began losing the ability to speak. He sang his last song to his infant daughter and fell into silence. But, now, with the help of 256 microelectrodes implanted directly into his motor cortex, he’s learning to talk once more. It isn’t easy.
Guests: Casey Harrell and Levana Saxon. You can donate to their GoFundMe here.
