Have you ever heard worms arguing? Deep-sea scientists use hydrophones to eavesdrop on “mouth-fighting worms.” It’s one of the many ways scientists are trying to catalog the diversity of the deep oceans — estimated to be comparable to a rainforest. But the clock is ticking. While vast expanses of the deep sea are still unexplored, mining companies are ready with dredging vehicles to strip mine the seafloor, potentially destroying rare and vulnerable ecosystems. Are we willing to eradicate an alien landscape that we haven’t yet visited? Guests: Craig McClain - deep-sea and evolutionary biologist and ecologist, Executive Director of the Louisiana Universities Marine Consortium. Steve Haddock - senior scientist at the Monetary Bay Aquarium Research Institute, and co-author of a New York Times op-ed about the dangers of mining. Emily Hall - marine chemist at the Mote Marine Laboratory, Sarasota, Florida Chong Chen - deep sea biologist with the Japan Agency for Marine-Earth Science and Technology (JAMSTEC) *Originally aired November 23, 2020 Big Picture Science is part of the Airwave Media podcast network. Please contact ad[email protected] to inquire about advertising on Big Picture Science.

Brace yourself for heatwave “Lucifer.” Dangerous deadly heatwaves may soon be so common that we give them names, just like hurricanes. This is one of the dramatic consequences of just a few degrees rise in average temperatures. Also coming: Massive heat “blobs” that form in the oceans and damage marine life, and powerful windstorms called “derechos” pummeling the Midwest.  Plus, are fungal pathogens adapting to hotter temperatures and breaching the 98.6 F thermal barrier that keeps them from infecting us? Guests: Kathy Baughman McLeod – director and senior vice president of the Adrienne Arsht-Rockefeller Foundation Resilience Center at The Atlantic Council Pippa Moore – Marine ecologist at Newcastle University in the U.K. Ted Derouin – Michigan farmer Jeff Dukes – Ecologist and director of Purdue Climate Change Research Center at Purdue University. Arturo Casadevall – Molecular microbiologist and immunologist at the Johns Hopkins School of Medicine Originally aired October 19, 2020 Big Picture Science is part of the Airwave Media podcast network. Please contact [email protected] to inquire about advertising on Big Picture Science.

Ready to become a space emigre? For half a century, visionaries have been talking about our future off-Earth – a speculative scenario in which many of us live in space colonies. So why haven’t we built them? Will the plans of billionaire space entrepreneurs to build settlements on Mars, or orbiting habitats that would be only minutes away from Earth, revive our long-held spacefaring dreams? And is having millions of people living off-Earth a solution to our problems… or an escape from them? Guests: Marianne Dyson – Author and former NASA flight controller Emily St. John Mandel – Author, most recently of “Sea of Tranquility” John Adams – Deputy Director, Biosphere 2, University of Arizona Featuring music by Dewey Dellay and Jun Miyake *Originally aired July 25, 2022 Big Picture Science is part of the Airwave Media podcast network. Please contact [email protected] to inquire about advertising on Big Picture Science.

Birds and bees do it … and so do fish. In a discovery that highlights the adaptive benefits of walking, scientists have discovered fish that can walk on land. Not fin-flap their bodies, mind you, but ambulate like reptiles.   And speaking of which, new research shows that T Rex, the biggest reptile of them all, wasn’t a sprinter, but could be an efficient hunter by outwalking its prey. Find out the advantage of legging it, and how human bipedalism stacks up. Not only is walking good for our bodies and brains, but not walking can change your personality and adversely affect your health.  Guests:  Hans Larsson – Paleontologist and biologist, and Director of the Redpath Museum at McGill University in Montréal. Shane O’Mara – Neuroscientist and professor of experimental brain research at Trinity College Dublin. He is the author of “In Praise of Walking.” Brooke Flammang – Biologist at the New Jersey Institute of Technology.

Your daily mucus output is most impressive. Teaspoons or measuring cups can’t capture its entire volume. Find out how much your body churns out and why you can’t live without the viscous stuff. But slime in general is remarkable. Whether coating the bellies of slithery creatures, sleeking the surface of aquatic plants, or dripping from your nose, its protective qualities make it one of the great inventions of biology. Join us as we venture to the land of ooze! Guests: Christopher Viney - Professor of materials science and engineering at the University of California, Merced Katharina Ribbeck - Bioengineer at MIT Anna Rose Hopkins - Chef and partner at Hank and Bean in Los Angeles Ruth Kassinger - author of “Slime: How Algae Created Us, Plague Us, and Just Might Save Us” *Originally aired January 27, 2020 Big Picture Science is part of the Airwave Media podcast network. Please contact [email protected] to inquire about advertising on Big Picture Science.
