Today we know that one of the easiest and most effective things you can do to protect yourself from the cold, flu, and other respiratory illnesses (including those like the novel coronavirus) is to wash your hands. But there was a time when that wasn't so obvious. Dana Tulodziecki, a professor at Purdue University, tells the story of Ignaz Semmelweis, the scientist who's credited with discovering the importance of handwashing. We'll hear how he figured it out and why there's more to the story. Follow host Maddie Sofia on Twitter @maddie_sofia. Email the show at shortwave@npr.org.

With the Iran nuclear deal in further jeopardy, we take a look at how the country's nuclear program began with NPR's Geoff Brumfiel. (The United States has a surprising role.)

For nearly forty years, the Guam Rail bird (locally known as the ko'ko') has been extinct in the wild — decimated by the invasive brown tree snake. But now, after a decades-long recovery effort, the ko'ko' has been successfully re-introduced. It is the second bird in history to recover from extinction in the wild. Wildlife biologist Suzanne Medina tells us the story of how the Guam Department of Agriculture brought the ko'ko' back, with a little matchmaking and a lot of patience.

Swarms of locusts can destroy crops and livelihoods. Right now, countries in East Africa are dealing with the threat. At a lab in Tempe, Arizona, researchers are trying to figure out how to minimize the crop damage these voracious pests can cause.
