What's Your Problem?

Every week on What’s Your Problem, entrepreneurs and engineers talk about the future they’re trying to build – and the problems they have to solve to get there.

How do you take a drone delivery service you’ve built in Rwanda and make it work in North Carolina? How do you convince people to buy a house on the Internet? How do you sell thousands of dog ramps to weiner dogs all across America when a pandemic breaks the global supply chain? 

Hosted by former Planet Money host Jacob Goldstein, What’s Your Problem helps listeners understand the problems really smart people are trying to solve right now.

Circadian rhythm isn’t just controlled by your brain. Every cell in your body runs on a 24-hour cycle, including your muscle cells. 

Karyn Esser is the chair of the department of physiology and aging at the University of Florida, and she’s a leading expert on circadian rhythm in muscle cells. Karyn's problem is this: How does the circadian rhythm in muscle cells change as we age, and how does exercise help keep our system in sync?

In this episode, Karyn explains: 
How every cell in your body has a clock in it
How muscle clocks prepare cells for work and schedule recovery during rest
How age affects these clocks’ ability to regulate effectively 
Why exercise can improve clock function 
Why jet lag and late-night eating can put your body clocks out of sync

Throughout the next few weeks, every Monday we'll be sharing some of our favorite episodes from Jacob's other show Business History. We hope you enjoy them and if you want to hear more, subscriber to Business History on Apple, Spotify or wherever you get your podcasts.

William Shockley was an electronics genius - he even won a Nobel Prize - but he was an awful boss. Shockley was a cruel, paranoid micromanager. And this annoyed the staff of brilliant young engineers he'd assembled in a quiet town in Northern California. In fact, they quit and set up a company of their own inventing silicon chips. 

Robert Noyce, Gordon Moore and the rest of "The Traitorous Eight" transformed computing, but also blazed a trail for the tech founders who would flock to Silicon Valley and change the world. Members of "The Traitorous Eight" set up Intel and AMD, while also funding businesses such as Google and Slack.

Why trust in agentic shopping will arrive category by category, not all at once
How a single old Reddit post erased a thriving brand from ChatGPT’s recommendations
Why someone needs to take on the liability risk when purchases go wrong
How treating AI as just another sales channel is the mistake the movie studios made with Netflix
