New Show: Universe of Art

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.

New Show: Science Diction

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!

Spontaneous Generation

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 a famous set of experiments, Pasteur showed that when you take a broth, boil it to kill all the microscopic organisms floating inside, and don’t let any dust get in, it stays dead. No life will spontaneously emerge.  His experiments have been considered a win for science—but according to historian James Strick, they might have actually been a win for religion.  This episode originally aired on Science Friday, when Elah joined Ira Flatow and science historian, James Strick, to find out what scientists of Pasteur’s day really thought of his experiment, the role the Catholic church played in shutting down “spontaneous generation,” and why even Darwin did his best to dodge the topic.   FOOTNOTES Though Darwin was bold enough to go public with his theory of evolution, he seemed to shy away from the spontaneous generation debate. But his theory inevitably invited the question: if life could spontaneously arise once on Earth, why not many times? James Strick writes about Darwin’s complicated relationship with spontaneous generation. The basic premise of Louis Pasteur’s famous swan-necked flask experiment is shown below. The swan necks let life-nourishing air into the flask, but kept potentially contaminating dust out. Louis Pasteur's spontaneous generation experiment illustrates the fact that the spoilage of liquid was caused by particles in the air rather than the air itself.

Into The Ether

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.

Planet Of The Killer Apes

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.   GUESTS Erika Milam, professor of history, Princeton University Agustín Fuentes, professor of anthropology, Notre Dame   FOOTNOTES Erika Milam’s book Creatures of Cain: The Hunt for Human Nature in Cold War America, elaborates on the Killer Ape theory. Robert Ardrey’s African Genesis, published in 1961, tells his account of the Killer Ape theory and his visit with Dr. Raymond Dart. Dr. Raymond Dart’s own narrative of his theory can be found in The Predatory Transition from Ape to Man. (Warning: bloody, over-the-top language ahead!)
