Until recently, nematodes weren’t known to live in the Great Salt Lake. And, in fact, very little lives there — because the lake’s salinity makes most life untenable. But, as it turns out, these tiny worms were doing just fine.

When humans debate climate policy, the questions asked are often posed in terms of what will work best. Fairness isn’t always, or even often, taken into account. But Stacia Ryder thinks that needs to change.

Ultra-processed food and the companies that produce them contribute significantly to the epidemic in diabetes, cancer, dementia, and other chronic disease. Is it time to regulate these products like tobacco? And will it take a class action suit to make that happen? Erik Peper believes so.

Memory is not a rigid, static picture of what came before. Rather, it’s a nebulous, ever-changing conceptualization of who we were, what we believed, what happened to us, and what was happening around us.

There is precedent for humans connecting with other living things, like getting attention, love, and companionship from dogs and cats and a few other animals that have been domesticated to provide partnership. Now, there’s a new option for meeting this need — social robots — who may end up being even better at fulfilling the human desire for connection.

He called it Anophthalmus hitleri — and sent Adolf Hitler a note announcing the onomastic tribute. After nearly 90 years, should species still be named after horrible people?

Long before Julius Caesar became one of the most powerful rulers in the world, he was a relatively unknown curator of the Via Appia, a road stretching from Rome on the Tyrrhenian Coast to the Salento Peninsula on the Adriatic Sea. Our guest John Keahey traversed the Via Appia, and he joins us to talk about it.

Slavery in the United States is often thought to be an institution of the American South, but western states played a part as well. In Utah, a law passed in 1852 made slavery and the slave trade legal, and this law was passed under the urging of the first territorial governor, Brigham Young.
