In 1832, Europe was in the throes of a cholera epidemic. A Scottish doctor named Thomas Latta knew cholera patients’ blood lacked water and salt, so he’d tried pumping a briny solution directly into the veins of an elderly patient. At first there was no response, but then the
It was March 1827 and Ludwig van Beethoven was dying. As he lay in bed, wracked with abdominal pain and jaundiced, grieving friends and acquaintances came to visit. And some asked a favor: Could they clip a lock of his hair for remembrance? The parade of mourners continued after Beethoven’
In 1747, the young poet Johann Wilhelm Ludwig Gleim was sitting in his study in the small German town of Halberstadt, surrounded by stacks of letters from his friends and associates, and had an epiphany. He realized that despite having corresponded with so many people, he had never actually met
On September 11, 1962, a German scientist vanished. Heinz Krug had been at his office, and he never came home. He was one of dozens of Nazi rocket experts who had been hired by Egypt to develop advanced weapons for that country. Based on interviews with former Mossad officers and
The 2022 Nobel Prize in physiology and medicine has brought fresh attention to paleogenomics, the sequencing of DNA of ancient specimens. Swedish geneticist Svante Pääbo won the coveted prize “for his discoveries concerning the genomes of extinct hominins and human evolution.” In addition to sequencing the Neanderthal genome and identifying
In the early days, CRISPR gene-editing technology was used to simply make cuts in DNA. Today, it’s being tested as a way to change existing genetic code, even by inserting all-new chunks of DNA or possibly entire genes into someone’s genome. These new techniques mean CRISPR could potentially
Justin Smith writes: "At a cultural moment when psychedelics are getting a second wind, and even someone as upstanding as Michael Pollan has moved from counseling us to eat our roughage to praising the benefits of microdosing, philosophers are conducting themselves as though it were still 1950, when we
In the fall of 1940, Thomas Midgley contracted polio, and the dashing, charismatic inventor soon found himself in a wheelchair, paralyzed from the waist down.

In the town of Bungamati, Nepal, above an ancient spring, stand two stone shrines and a temple. One of those shrines has a large hole where a statue of Shreedhar Vishnu, the Hindu protector god, used to be. Carved by master artisans nearly a thousand years ago, the sandstone god
Brenda Leyland was a stylish, well-spoken and rather private woman who lived in a picturesque village in Leicestershire. Her son Ben knew she told stories, and that some of them may have been on the tall side. He also knew that she spent a lot of time on her laptop
In November 1949, Chien-Shiung Wu and her graduate student, Irving Shaknov, descended to a laboratory below Columbia University's Pupin Hall. They needed antimatter for a new experiment, so they made their own, using a machine called a cyclotron. Their evidence suggested that pairs of photons from particle collisions
Marie Tharp spent the fall of 1952 hunched over a drafting table, surrounded by charts, graphs, and jars of India ink. Nearby, spread across several additional tables, lay her project—the largest and most detailed map ever produced of a part of the world no one had ever seen. For
