The Disappearing Spoon: a science history podcast with Sam Kean
A topsy-turvy science-y history podcast by Sam Kean. I examine overlooked stories from our past: the dental superiority of hunter-gatherers, the crooked Nazis who saved thousands of American lives, the American immigrants who developed the most successful cancer screening tool in history, the sex lives of dinosaurs, and much, much more. These are charming little tales that never made the history books, but these small moments can be surprisingly powerful. These are the cases where history gets inverted, where the footnote becomes the real story.

The Publicity Stunt that Sparked the Scopes Monkey Trial 16.12.2025 18:59
Exactly a century ago, teacher John Scopes was charged with the “crime” of teaching evolution. But Scopes was hardly a defiant Galileo, nobly standing up for truth. In fact, he never even taught evolution. (Really.) But despite the unseemly origins of the Monkey Trial, Scopes proved himself a genuine hero...

Why Not Just Rename the “Hitler Beetle”? 04.11.2025 19:18
Taxonomy has a sadly ugly history of naming species after despicable people—even Adolf Hitler. Given the controversy these names generate, there have been many calls to drop them.

John James Fraudubon 28.10.2025 18:17

The Dignity of the Ig Nobel Prizes 14.10.2025 18:27
The Ig Nobel Prize is the bizarro cousin of the Nobel Prize—awarded for odd or unusual research “that first makes you laugh, then makes you think.” Some scientists hate them, and have refused to accept the award.

Why Doctors and Scientists Embraced the Nazis 27.05.2025 21:19

The Worst of Times, the Asbestos Times 06.05.2025 17:47
Asbestos was once considered a miracle substance—a wonder of the modern age, due to its role in stopping the fires that once plagued every major city. Unfortunately, it also shreds people’s lungs. Most countries were willing to live with that trade-off, until a crusading doctor named Irving Selikoff made it his life's mission to get asbestos banned.
