Science Friday’s new podcast about science-inspired art is out now!

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.

Americans haven’t always loved whales and dolphins. In the 1950s, the average American thought of whales as the floating raw materials for margarine, animal feed, and fertilizer—if they thought about whales at all. But twenty-five years later, things had changed for cetaceans in a big way. Whales had become the poster-animal for a new environmental movement, and cries of “save the whales!” echoed from the halls of government to the whaling grounds of the Pacific. What happened? Annie and Elah meet the unconventional scientists who forever changed our view of whales by making the case that a series of surreal bleats and moans were “song.”

Travis Thomas is a rookie turtle researcher in Florida. He was on the verge of publishing his first big paper and naming two new species of turtle when he found out he’d been scooped by a stranger in Australia: Raymond Hoser, a.k.a. the Snake Man. Raymond is a reptile wrangler and amateur herpetologist who’s managed to name hundreds of animals—and has made a lot of enemies in the process. In this episode of Undiscovered, Travis sets out to get his turtles back, and Annie and Elah set out to find out how and why the Snake Man does what he does.

This week, Annie and Elah share an episode from one of their favorite podcasts, the Australian Broadcasting Corporation’s Sum of All Parts. For years, Robert Schneider lived the indie rocker’s dream, producing landmark records and fronting his band, The Apples in Stereo. And then, he gave it all up...for number theory. Host Joel Werner tracks Robert’s transformation, from a transcendental encounter with an old tape machine, to the family temple of a mysterious long-dead mathematician, Ramanujan.

Are non-native species all that bad, or are we just prejudiced against “the Other”? In the San Francisco Bay Area, one particular foreign species has been dividing environmentalists for years: the blue gum eucalyptus. Eucalyptus opponents say it’s a serious fire hazard. Defenders say there’s no good evidence it’s worse than native plants. Which is it? And is the fight against non-native species grounded in science or xenophobia? In this episode of Undiscovered, Annie and Elah investigate.

As a critical care doctor, Jessica Zitter has seen plenty of “Hail Mary” attempts to save dying patients go bad—attempts where doctors try interventions that don’t change the outcome, but do lead to more patient suffering. It’s left her distrustful of flashy medical technology and a culture that insists that more treatment is always better. But when a new patient goes into cardiac arrest, the case doesn’t play out the way Jessica expected. She finds herself fighting for hours to revive him—and reaching for a game-changing technology that uncomfortably blurs the lines between life and death.

Since the 1980s, Gerta Keller, professor of paleontology and geology at Princeton, has been speaking out against an idea most of us take as scientific gospel: That a giant rock from space killed the dinosaurs. Nice story, she says—but it’s just not true. Gerta's been shouted down and ostracized at conferences, but in three decades, she hasn’t backed down. And now, things might finally be coming around for Gerta’s theory. But is she right? Did something else kill the dinosaurs? Or is she just too proud to admit she’s been wrong for 30 years?

A decade ago, psychologists introduced a group of kids to Robovie, a wide-eyed robot who could talk, play, and hug like a pro. And then, the researchers did something heartbreaking to Robovie! They wanted to see just how far kids’ empathy for a robot would go. What the researchers didn’t gamble on was just how complicated their own feelings for Robovie would get.

Annie and Elah are back with tales of dinosaurs, robots, and more!

It’s been two years since we followed MIT scientist Kevin Esvelt to Martha’s Vineyard. Has he created his Lyme-fighting super-mouse? We follow up.

Martha’s Vineyard has a Lyme disease problem. Now a scientist is coming to town with a possible fix: genetically engineered mice. An island associated with summer rest and relaxation is gaining a reputation for something else: Lyme disease. Martha’s Vineyard has one of the highest rates of Lyme in the country. Now MIT geneticist Kevin Esvelt is coming to the island with a potential long-term fix. The catch: It involves releasing up to a few hundred thousand genetically modified mice onto the island. Are Vineyarders ready? Kevin Esvelt makes the case for engineered mice, at a public meeting at a Vineyard public library.
