Description
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.

There’s only one thing Dr. John Haldane loved more than running dangerous experiments on himself—running them on his son Jack. But the duo would revolutionize our understanding of the human body.Advertising Inquiries: https://redcircle.com/brandsPrivacy & Opt-Out: https://redcircle.com/privacy
When Charles Lindbergh's sister-in-law developed heart trouble, he teamed up with a Nobel-Prize-winning doctor to save her.

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...

In the 1970s, paramedic units were illegal in the United States. One (very bad) television show, Emergency!, set out to change that—and saved tens of thousands of lives in the process.

He was a brilliant ornithologist—and a spy so colorful that James Bond was based on him. Richard Meinertzhagen was also a liar and a thief, and perpetrated the biggest fraud in biology history. Episode below!

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. But taxonomists have so far resisted most of these efforts, for reasons both good and bad...

The eagle that made John James Audubon famous, the Bird of Washington was nothing but an elaborate lie. Fawning biographers have suppressed this fact for years, but careful historical work has unraveled the Audubon legend, and shown that much of his life, and work, was built on deceit. (Part 2 of 2)

After several heartbreaking setbacks, John James Audubon’s career was in ruins—until he hatched a desperate plan to win new patrons. It involved a rare American eagle, the Bird of Washington. And when the gamble paid off, it made Audubon the most famous ornithologist in history...

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. But they’ve grown into a beloved institution—and one with some surprising benefits to science.

Winning a Nobel Prize is a good thing—mostly. But surprisingly often, Nobel laureates go kooky and start promoting bizarre things like homeopathy, ESP, AIDS denialism, and worse. Psychologists are starting to understand why...

Nazism was a society-wide catastrophe for Germany, but some professions deserve more blame than others. In particular, there was a surprisingly large percentage of doctors and engineers among the Nazis. Sociologists and historians have now worked out why.

When Charles Dickens published Bleak House in 1852, he included a scene where one character spontaneously combusts. 🔥 🔥 🔥 Readers loved it, but one of Dickens’s good friends—a former scientist—blasted Dickens for his scientific ignorance. It ignited one of the strangest controversies in literary history.

It was one the largest epidemics in American history: 30,000 people paralyzed over a few months in 1930. A dogged epidemiologist eventually traced the cause to adulterated bottles of an illegal liquor/medicine called “jake.” Yet the epidemic is almost completely forgotten. About the only place it survived was in blues songs...

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.

Rickets was once a devastating disease: up to 90 percent of the children showed symptoms in some cities, including bent spines and bowed legs, and it resulted in many women dying during childbirth. The search for the cause of rickets took decades, and ended with a startling discovery—that much like plants, human beings had the ability to photosynthesize.

Leonard Darwin had a lot to live up to. He was the son of the legendary Charles, and several siblings proved to be brilliant scientists as well. But Leonard never quite measured up as a mediocre military officer and two-bit politician. In his fifties, he pronounced his life a “failure.” But in his sixties, he finally found his calling—the dark pseudoscience of eugenics, a field he embraced in part to prove that he wasn’t the failure he imagined.

A young woman in the mid-1900s couldn’t take an at-home pregnancy test. Instead, she sent a vial of urine to a clinic, where a technician would, of all things, inject it into a frog, and hormones in the urine would cause the frog to lay eggs. This frog-based test was far faster, easier, and cleaner than any pregnancy test before, and it shifted power for family planning from doctors to women themselves.

After scientists had a handle on how many chromosomes humans have, other researchers began exploring whether certain ailments might be caused by chromosomal abnormalities. To this end, a French cardiologist discovered that Down syndrome was caused by the presence of an extra chromosome in humans. But a colleague stole credit for her work, and the battle over their legacies continues to this day, in part because the colleague is on track to become a certified Catholic saint.

It seems like a simple question: how many chromosomes do human beings have? But getting an accurate count proved surprisingly hard for much of last century. In fact, virtually every textbook once cited an incorrect number, until in 1956, a fiery Indonesian scientist finally determined the true count—and had to battle his boss over who would receive credit for this legacy-making discovery.
