Late last month, President Trump announced that the United States would be restarting nuclear weapons tests after a break of over 30 years. We’ve since learned that they won’t be the explosive kind of tests, but this sent us down a rabbit hole — where we found a story about dinosaurs, Carl Sagan, and nuclear war. Because there was a moment in the not-so-distant past when we learned what drove the dinosaurs extinct... and that discovery, made during the Cold War, may have helped save humans from the same fate. This episode originally published in March 2025.

Guests:

David Sepkoski, Thomas M. Siebel Chair in History of Science at the University of Illinois and author of Catastrophic Thinking: Extinction and the Value of Diversity. 

Owen Brian Toon, professor of atmospheric and oceanic sciences at the University of Colorado Boulder.

Journalism is under unprecedented threat worldwide. At least 220 journalists have been killed in Gaza alone since the October 7th, 2023 Hamas-led attack on Israel; the Committee to Protect Journalists says it’s the deadliest conflict for journalists the group has ever documented. In conflicts around the world, it’s war reporters who write the first draft of history. But getting to the front lines, finding the truth, and reporting it is easier said than done. Today on the show: war reporters, and what’s at stake if they can’t do their jobs.

In this episode: the roots of the modern anti-vaccine movement, and of the fears that still fuel it – from a botched polio vaccine, to the discredited autism study, to today. This episode originally published in February 2025.
