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, MassachusettsStan 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 MiyakeBig Picture Science is part of the Airwave Media podcast network. Please contact sales@advertisecast.com to inquire about advertising on Big Picture Science.You can get early access to ad-free versions of every episode by joining us on Patreon.

Shipwrecks are scenes of tragedy, but they are also bits of history frozen in time that can provide insights into events and ideas from long ago. That is, if we can find them. From an 11th century Viking sailing ship to a WW II era British cargo ship with a mailbag of letters onboard amazingly preserved, an underwater archeologist takes us on a deep dive into history.Guest:David Gibbins - underwater archeologist, novelist, and the author of nonfiction, including his latest book, “The History of the World in Twelve Shipwrecks”.Featuring music by Dewey Dellay and Jun MiyakeBig Picture Science is part of the Airwave Media podcast network. Please contact sales@advertisecast.com to inquire about advertising on Big Picture Science.You can get early access to ad-free versions of every episode by joining us on Patreon.

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 teamTed Chiang – Nebula and Hugo award-winning science fiction writer, best known for his collections, Stories of Your Life and Others and ExhalationDouglas Vakoch – Founder and president of METI International, a nonprofit research and educational organization devoted to transmitting intentional signals to extraterrestrial civilizationsFeaturing music by Dewey Dellay and Jun Miyake*Originally aired April 3, 2023Big Picture Science is part of the Airwave Media podcast network. Please contact advertising@airwavemedia.com to inquire about advertising on Big Picture Science.You can get early access to ad-free versions of every episode by joining us on Patreon.

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 AlabamaPaul Byrne – Associate professor of Earth and Planetary Sciences at Washington University in St. LouisRobin 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 MiyakeOriginally aired May 29, 2023Big Picture Science is part of the Airwave Media podcast network. Please contact sales@advertisecast.com to inquire about advertising on Big Picture Science.You can get early access to ad-free versions of every episode by joining us on Patreon.

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 LaboratoryStephen 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, DublinTom 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 DiegoTom Patterson – Professor of psychiatry at the University of California San DiegoFeaturing music by Dewey Dellay and Jun MiyakeYou 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 UniversityFeaturing music by Dewey Dellay and Jun MiyakeYou 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”.
