They look like a cross between a beaver and a duck, and they all live Down Under. The platypus may lay eggs, but is actually a distant mammalian cousin, one that we last saw, in an evolutionary sense, about 166 million years ago. Genetic sequencing is being used to trace that history, while scientists intensify their investigation of the habits and habitats of these appealing Frankencreatures; beginning by taking a census to see just how many are out there, and if their survival is under threat. Guests:  Josh Griffiths – Senior Wildlife Ecologist at Cesaar Australia. Jane Fenelon – Research fellow, University of Melbourne Paula Anich – Professor of Natural Resources, Northland College Wes Warren – Professor of Genomics, University of Missouri Phoebe Meagher – Conservation Officer, Taronga Conservation Society, Australia Originally aired August 2, 2021 Featuring music by Dewey Dellay and Jun Miyake Big Picture Science is part of the Airwave Media podcast network. Please contact advertising@airwavemedia.com to inquire about advertising on Big Picture Science.

What is life? Even as the search for life in the universe evolves, surprisingly, there is no consensus on what life is. We must consider hunting for life not as we know it.  The existence of extremophiles on Earth has broadened the types of environments in which we might look for life elsewhere in our solar system. And recent missions to dwarf planets has shown that our solar system is replete with the geology that might harbor biology. In this second episode, Shannon Geary talks with astrobiologist Nathalie Cabrol, the director of the Carl Sagan Center for Research at the SETI Institute about her early interest in astrobiology, meeting Carl Sagan, and the evolving definition of life.

The idea that the universe is made of tiny vibrating strings was once the science theory du jour. String theory promised to unite the disparate theories describing particles and gravity, and many people, not just scientists, were optimistic that a theory of everything might be within our grasp. But here we are, many years later, and string theory doesn’t seem to have delivered on its initial promise. What happened? We consider the science around string theory in this episode of Skeptic Check. Guest: Brian Greene – Physicist and mathematician at Columbia University, and author of The Elegant Universe: Superstrings, Hidden Dimensions, and the Quest for the Ultimate Theory.

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. Co-author of Parasites: The Inside Story.

Whether in miles or pounds, meters or kilograms, we take daily measure out our lives. But how did these units ever come to be, and why do we want to change them? From light-years to leap seconds, we look at the history of efforts to quantify our lives and why there’s always room for greater precision. Plus, we debate the virtues of staying imperial measurements vs. going metric.

Air conditioning and refrigeration may beat the heat, but they also present a dilemma. The more we use them, the more greenhouse gases we emit, the hotter the planet becomes, and the more we require artificial cooling. Can we escape this feedback loop? We look at the origins of these chilling technologies, tour the extensive chain of cold that keeps food from perishing, and consider how a desert city like Phoenix could not exist without AC. Guests: Nicola Twilley – co-host of the Gastropod podcast, a contributing writer at The New Yorker, and the author of “Frostbite: How Refrigeration Changed Our Food, Our Planet, and Ourselves” Erik Morrison – Chief cooling engineer at Transaera, Somerville, Massachusetts Stan Cox – Lead scientist at the Land Institute, author of “Losing Our Cool: The Uncomfortable Truths about our Air-Conditioned World” Featuring music by Dewey Dellay and Jun Miyake Big Picture Science is part of the Airwave Media podcast network. Please contact sales@advertisecast.com to inquire about advertising on Big Picture Science.

Are we alone? The search for life in the universe is on! For 40 years, the SETI Institute has been a leader in the search for life and intelligence beyond Earth. Recent discoveries, such as exoplanets, have brought us closer than ever to answering the question of whether we are alone in the universe. To honor the Institute’s pioneering past as we look ahead to its future, Big Picture Science presents a new monthly podcast series highlighting the groundbreaking research of the SETI Institute. In this first episode, Molly talks with Bill Diamond, SETI Institute President and CEO, about the founding of the SETI Institute, radio telescope arrays, and the New Copernican Revolution.

Are we alone in the universe? Is there other intelligence out there? COSMIC, the most ambitious SETI search yet, hopes to answer that. We hear updates on this novel signal detection project being conducted on the Very Large Array in the desert of New Mexico.  Also, we chat with award-winning science fiction writer Ted Chiang about how he envisions making contact with aliens in his stories, including the one that was the basis for the movie Arrival. And find out why some scientists don’t want only to listen for signals, they want to deliberately transmit messages to aliens. Is that wise and, if we did it, what would we say?  Guests: Chenoa Tremblay – Postdoc researcher in radio astronomy for the SETI Institute and member of COSMIC science team Ted Chiang – Nebula and Hugo award-winning science fiction writer, best known for his collections, Stories of Your Life and Others and Exhalation Douglas Vakoch – Founder and president of METI International, a nonprofit research and educational organization devoted to transmitting intentional signals to extraterrestrial civilizations Featuring music by Dewey Dellay and Jun Miyake *Originally aired April 3, 2023 Big Picture Science is part of the Airwave Media podcast network. Please contact advertising@airwavemedia.com to inquire about advertising on Big Picture Science.

Spewing lava and belching noxious fumes, volcanoes seem hostile to biology. But the search for life off-Earth includes the hunt for these hotheads on other moons and planets, and we tour some of the most imposing volcanoes in the Solar System.  Plus, a look at how tectonic forces reshape bodies from the moon to Venus to Earth. And a journey to the center of our planet reveals a surprising layer of material at the core-mantle boundary. Find out where this layer was at the time of the dinosaurs and what powerful forces drove it deep below. Guests: Samantha Hansen – Geologist at the University of Alabama Paul Byrne – Associate professor of Earth and Planetary Sciences at Washington University in St. Louis Robin George Andrews – Science journalist and author of “Super Volcanoes: What They Reveal about Earth and the Worlds Beyond” Featuring music by Dewey Dellay and Jun Miyake Originally aired May 29, 2023 Big Picture Science is part of the Airwave Media podcast network. Please contact sales@advertisecast.com to inquire about advertising on Big Picture Science.

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.

We’re hurtling towards a post-antibiotic world, as the overuse of antibiotics has given rise to dangerous drug-resistant bacteria. Can we fight back using viruses as weapons? An obscure medical therapy uses certain viruses called bacteriophages to treat infection. For a century attempts to turn phage-therapy into a life-saving treatment have faltered, but today there’s renewed interest in this approach. Can we use phages to forestall the antibiotic crisis?  Guests: Claas Kirchhelle – Medical historian at the University College, Dublin Tom Ireland – Journalist, editor of The Biologist and author of “The Good Virus: The Amazing Story and Forgotten Promise of the Phage” Steffanie Strathdee – Associate Dean of Global Health Sciences at the University of California San Diego Tom Patterson – Professor of psychiatry at the University of California San Diego Featuring music by Dewey Dellay and Jun Miyake You can get early access to ad-free versions of every episode by joining us on Patreon.

Social media use among teens has risen alongside rates of anxiety and depression. Addressing what he calls a mental health crisis, the Surgeon General has called for warning labels on social media platforms akin to those on tobacco and alcohol. But this comes before scientific consensus has been reached that social media causes harm. We consider the evidence that social media may be eroding the mental health of Gen Z and a challenge to the claim that presents an alternative explanation for why young people are struggling. Guests: Alison – High schooler who wrote a column describing the positive and negative effects of social media  Zach Rausch – Associate Research Scientist at NYU-Stern School of Business and lead researcher to Social Psychologist Jonathan Haidt for his book, “The Anxious Generation: How the Great Rewiring of Childhood Is Causing an Epidemic of Mental Illness” Sarah Coyne – psychologist and Sarah Coyne Associate Director of the School of Family Life at Brigham Young University Featuring music by Dewey Dellay and Jun Miyake You can get early access to ad-free versions of every episode by joining us on Patreon.

Have scientists discovered an alphabet in whale calls? As researchers try to decipher the series of clicks made by sperm whales, we ask whether these cetaceans might have language, and if it follows that whales are thinking animals too. Could we one day get a peek into the thoughts of a humpback whale? Meanwhile, somewhere along the long path of evolution, one species emerged with an impressive gift for gab. Are speech and language unique human superpowers? Guests: Carl Zimmer – Columnist, The New York Times, including the article, “Scientists Find an ‘Alphabet’ in Whale Songs”.
