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.

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.

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.

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.

UFOs are back. This time they’ve landed on Capitol Hill in the form of a public, congressional hearing. We watched the hearing with great interest, but felt dissatisfied when it came to evidence. Claims that the government has alien technology are obviously tantalizing. So tantalizing, in fact, that it’s easy to overlook logical fallacies in how these claims are presented. We identify a few of the missteps. But what would convince you that the government is aware of alien visitation? Is the word of an authority figure all we need to accept that “they’re here?” Guests: Benjamin Radford - Research fellow with the Committee for Skeptical Inquiry Nadia Drake - Science journalist and member of NASA’s UAP group James McGaha - Retired military pilot and astronomer he's a longtime investigator of UFO reports and claims and he's a scientific consultant to the Committee for Skeptical Inquiry Mick West - A skeptical investigator who looks at claims of UFOs Featuring music by Dewey Dellay and Jun Miyake Big Picture Science is part of the Airwave Media podcast network.

Imagine tapeworms longer than the height of an adult human. Or microbes that turn their hosts into zombies. If the revulsion they induce doesn’t do it, the sheer number of parasites force us to pay attention. They are the most abundant form of animal life on Earth. Parasites can cause untold human suffering, like those that cause African River Blindness or Lyme disease, but their presence is also a sign of a health ecosystem. A parasitologist whose lab contains the largest parasite collection in the world gives us the ultimate inside story about these organisms. Guest: Scott Gardner - curator of parasites in the H.W. Manter Laboratory of Parasitology at the University of Nebraska State Museum, one of the largest collections of parasites in the world, and professor of biological sciences at University of Nebraska.

Crowded subway driving you crazy? Sick of the marathon-length grocery store line? Wish you had a hovercraft to float over traffic? If you are itching to hightail it to an isolated cabin in the woods, remember, we evolved to be together. Humans are not only social, we’re driven to care for one another, even those outside our immediate family. We look at some of the reasons why this is so – from the increase in valuable communication within social groups to the power of the hormone oxytocin. Plus, how our willingness to tolerate anonymity, a condition which allows societies to grow, has a parallel in ant supercolonies.

We have too much “bad fire.” Not only destructive wildfires, but the combustion that powers our automobiles and provides our electricity has generated a worrying rise in atmospheric carbon dioxide. And that is driving climate change which is adding to the frequency of megafires. Now we’re seeing those effects in “fire-clouds,” pyrocumulonimbus events. But there’s such a thing as “good fire.” Indigenous peoples managed the land with controlled fires, reaped the benefits of doing so, and they’re bringing them back. So after millions of years of controlling fire, is it time for us to revisit our attitudes and policies, not just with regard to combustion, but how we manage our wildfires? Guests: David Peterson - Meteorologist, U.S. Naval Research Laboratory Stephen Pyne - Emeritus professor at Arizona State University, fire historian, urban farmer, author of “The Pyrocene: How We Created an Age of Fire, and What Happens Next” Richard Wrangham - Ruth B.
