Mini: The Undercover Botanist

Hey Undiscovered listeners! We’re back to tell you about a brand new show from Science Friday. Universe Of Art is a podcast about artists who use science to take their creations to the next level.Hosted by SciFri producer and musician D. Peterschmidt, each episode of Universe Of Art will focus on a different artist (or scientist) about how science played a role in their creative process, and what we can learn by combining two seemingly unrelated fields together. We’ll hear from astronomers who integrate space into their artwork, drag performers who bring science into their acts, and many others. Here’s a sneak peak.Listen to Universe Of Art wherever you get your podcasts.

Hello Undiscovered fans! We're here to tell you about a new show we've been working on at Science Friday. Science Diction is a podcast about words—and the science stories behind them. Hosted by SciFri producer and self-proclaimed word nerd Johanna Mayer, each episode of Science Diction digs into the origin of a single word or phrase, and, with the help of historians, authors, etymologists, and scientists, reveals a surprising science connection. Here's a sneak peek!

These days, biologists believe all living things come from other living things. But for a long time, people believed that life would, from time to time, spontaneously pop into existence more often—and not just that one time at the base of the evolutionary tree. Even the likes of Aristotle believed in the “spontaneous generation” of life until Louis Pasteur debunked the theory—or so the story goes. 

In 1880, scientist Albert Michelson set out to build a device to measure something every 19th century physicist knew just had to be there. The “luminiferous ether” was invisible and pervaded all of space. It helped explain how light traveled, and how electromagnetic waves waved. Ether theory even underpinned Maxwell’s famous equations! One problem: When Alfred Michaelson ran his machine, the ether wasn’t there.  Science historian David Kaiser walks Annie and Science Friday host Ira Flatow through Michaelson’s famous experiment, and explains how a wrong idea led to some very real scientific breakthroughs. This story first aired on Science Friday.   GUEST David Kaiser, Germeshausen Professor of the History of Science, Professor of Physics, the Massachusetts Institute of Technology   FOOTNOTES Find out more about the Michelson-Morley experiment on APS Physics.  Read an archival article from the New York Times about the physicists’ experimental “failure.”   CREDITS This episode of Undiscovered was produced by Annie Minoff and Christopher Intagliata. Our theme music is by I Am Robot And Proud. 

In Apartheid-era South Africa, a scientist uncovered a cracked, proto-human jawbone. That humble fossil would go on to inspire one of the most blood-spattered theories in all of paleontology: the “Killer Ape” theory.  According to the Killer Ape theory, humans are killers—unique among the apes for our capacity for bloodthirsty murder and violence. And at a particularly violent moment in U.S. history, the idea stuck! It even made its way into one of the most iconic scenes in film history. Until a female chimp named Passion showed the world that we might not be so special after all.

“Do men need to cheat on their women?” a Playboy headline asked in the summer of 1978. Their not-so-surprising conclusion: Yes! Science says so! The idea that men are promiscuous by nature, while women are chaste and monogamous, is an old and tenacious one. As far back as Darwin, scientists were churning out theory and evidence that backed this up. In this episode, Annie and Elah go back to the 1970s and 1980s, when feminism and science come face to face, and it becomes clear that a lot of animals—humans and bluebirds included—are not playing by the rules.

In 1767, a young French servant sailed around the world, collecting plants previously unknown to Western science. The ship’s crew knew the servant as “Jean,” the scrappy aide to the expedition’s botanist. But “Jean” had a secret. She was actually Jeanne Baret, a woman disguised as a man—and she was about to make botanical history. Annie and Elah told this story for a live audience at On Air Fest a few weeks ago. 

Undiscovered is back between seasons with a listener question: What saved the cats? If you rewind to the Middle Ages, cats and humans were on bad terms. Cat roundups, cat torture, and even cat murder were common occurrences throughout Europe. But a series of historic events steadily delivered the tiny felines into public favor. In a story that spans centuries and continents, the Catholic Church and the Rosetta Stone, Elah and Annie investigate how the cat’s reputation shifted from devil’s minion to adored companion.

In this Undiscovered Cares Report, Annie and Elah dig into a scary science headline to help Elah’s friend, David, figure out how scared he should be that his B12 vitamins will give him lung cancer. And we find out how—even with top-notch scientists, journalists, and readers—science communication can go very wrong.

In 2016, a North Carolina legislator announced that his party would be redrawing the state’s congressional district map with a particular goal in mind: To elect “10 Republicans and three Democrats.” His reasoning for this? As he explained, he did “not believe it’s possible to draw a map with 11 Republicans and two Democrats.” It was a blatant admission of gerrymandering in a state already known for creatively-drawn districts. But that might be about to change. A North Carolina mathematician has come up with a way to quantify just how rigged a map is. And now he’s taking his math to court, in a case that could end up redrawing district lines across the country.
