Short Wave Folgen

This year, the hottest July ever was recorded — and parts of the country were hit with heat waves that lasted for weeks. Heat is becoming increasingly lethal as climate change causes more extreme heat. So in today's encore episode, we're exploring heat. NPR climate correspondent Lauren Sommer talks with Short Wave host Regina G. Barber about how the human body copes with extended extreme heat and how today's heat warning systems could better protect the public. If you can, stay cool out there this Labor Day, dear Short Wavers.What science story do you want to hear next on Short Wave?

Food allergies have risen in the United States over the last few decades. Research suggests that 40 years ago the actual prevalence of food allergies was less than 1%. But this year, the Centers for Disease Control and Prevention (CDC) released data showing that almost 6% of U.S. adults and children have a food allergy. But this trend is not present in all countries — and what people are allergic to varies globally. Today, we dive into the complex world of food allergies with Dr. Waheeda Samady. She's the Director of Clinical Research at Northwestern University's Center for Food Allergy and Asthma Research.Have a science question?

Smallpox is a deadly virus. At one point, it killed almost 1 in 3 people who had it. Almost 300 million of those deaths were in the 20th century alone. It was extremely painful, highly contagious and many people thought it would be impossible to wipe out—until it was. On May 8, 1980. the 33rd World Health Assembly declared the world free of smallpox. This marked the first—and only—time a human disease was eradicated globally. Epidemiologist and host of the podcast Epidemic: Eradicating Smallpox Céline Gounder has been looking into this history. Today, she shares the intense journey to eradicate smallpox in Bangladesh (spoiler alert: there are literal speedboats) and reflects on what this history tells us about the importance of healthcare that meets the needs of individuals and communities today.
