• Climate Change + Baseball = More Home Runs

  Baseball season is nigh! From Yankee stadium in New York to Dodger stadium in Los Angeles, teams around the country will face off Thursday to mark the start of the 2025 MLB season. And when we here at Short Wave think of baseball, we naturally think of physics. To get the inside scoop on the physics of baseball, like how to hit a home run, we talk to Frederic Bertley, CEO and President of the Center of Science and Industry, a science museum in Columbus, Ohio. In this encore episode, he also talks to host Regina G. Barber about how climate change is affecting the game.Interested in the science of other sports?

• What Scientists Got Wrong About COVID-19

  Early in the beginning of the COVID-19 pandemic, scientists predicted the SARS-CoV-2 virus would mutate slowly. They were wrong. Hundreds of thousands of viral mutations and multiple seasonal waves later, we now know why. The answer changes researchers' understanding of viral evolution — and it could help predict the evolution of other viruses in the future. Emily talks about it all with Sarah Zhang, a health writer for The Atlantic. Want to hear more virology or human biology stories?
