Why is the media so full of bad news? Also: things you never knew you wanted to know about wolves, bananas, pollution, search engines, and the quirks of human behavior.

Last week, we heard a former U.S. ambassador describe Russia’s escalating conflict with the U.S. Today, we revisit a 2019 episode about an overlooked front in the Cold War — a “farms race” that, decades later, still influences what Americans eat.

We also talk about the state of cancer care, mysteries in the gut microbiome, flaws in the U.S. healthcare system — and what a second Trump term means for healthcare policy.
