Heard weekly on WHYY and other NPR member stations, The Pulse tells stories at the heart of health, science and innovation.

Why do you wait forever in your doctor’s office? Can we stop asteroids from smashing into Earth? What’s with people’s love of round numbers? Why do some of us cry after anesthesia? How much should an MRI cost, really?

The Pulse explores the questions that make people go, “Yeah, why is that?” It tells stories from ground level, where illness, healing and discovery are personal. The Pulse celebrates science, and covers breakthroughs with healthy skepticism.
