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.

The Sad Story of Darwin’s Self-Procleimed “Stupidest” Child
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.

The Birds and the Bees and the Frogs
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.

The Would-Be Saint's Battle over Down Syndrome
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.

The Battle over Human Chromosomes
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.

Über 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.
