Science Friday Folgen

There is a murderous crime spree happening right under—and perhaps inside—our noses. Killer microbes armed with weapons are eviscerating, assassinating, and detonating their fellow microbes. And the newest culprit? A protist that morphs into a cannibilastic supergiant when times get tough.  Host Flora Lichtman talks with Glen D’Souza and Ben Larson, two detectives who study these micro-murders. They chat about why microbes kill, how they choose their victims, and whether we can harness those weapons for good.  Guests: Dr. Glen D’Souza is a microbiologist and assistant professor at Arizona State University in Tempe.  Dr. Ben Larson is an assistant professor and cell biologist at Rensselaer Polytechnic Institute in New York.  Transcripts for each episode are available within 1-3 days at sciencefriday.com.

Do you ever hear a song that transports you to a specific place and time? This auditory wormhole has a name: musical daydreams. Music cognition expert Elizabeth Margulis studies why they happen, and what they tell us about our brains. She joins Host Flora Lichtman to discuss this phenomenon. Guest: Dr. Elizabeth Margulis is a professor and director of Princeton’s Music Cognition Lab. She’s also the author of “Transported: The Everyday Magic of Musical Daydreams.” Other episodes you may enjoy: A Neurologist Investigates His Own Musical Hallucinations Oliver Sacks Searched The Brain For The Origins Of Music Transcripts for each episode are available within 1-3 days at sciencefriday.com.

Researchers just published details of a massive undersea graveyard of whales deep in the Indian Ocean. Spanning about 1,200 kilometers (745 miles), it contains whale remains dating back more than 5 million years—and at least five active whale fall sites still teeming with life. Fossil whale expert Nick Pyenson joins Host Flora Lichtman to discuss these findings. Then, marine biologists Rachel Sipler and Sara Jobson join Ira Flatow to describe an unusual discovery in certain species of sea cucumbers: If a foot or tentacle becomes detached, the parts don’t wither up and rot away. Even without a stomach, these parts appear to directly extract nutrients from the surrounding seawater. “Zombie” sea cucumber parts have been observed surviving for more than three years. Guests: Dr. Nick Pyenson is curator of fossil marine mammals at the Smithsonian National Museum of Natural History. Dr. Rachel Sipler is a senior research scientist in the Bigelow Laboratory in East Boothbay, Maine. Sara Jobson a PhD student at the Memorial University of Newfoundland in St. Johns, Canada.
