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. Featuring music by Dewey Dellay and Jun Miyake Originally aired July 31, 2023 Big Picture Science is part of the Airwave Media podcast network.

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.

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. Moore Research Professor of Biological Anthropology at Harvard University and author of "Catching Fire: How Coooking Made Us Human" Margo Robbins - Co-founder and president of the Cultural Fire Management Council (CFMC), organizer of the Cultural Burn Training Exchange (TREX) that takes place on the Yurok Reservation twice a year, and an enrolled member of the Yurok Tribe Originally aired May 9, 2022 Featuring music by Dewey Dellay and Jun Miyake Big Picture Science is part of the Airwave Media podcast network.

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.
