Big Picture Science

A thousand years ago, most people didn’t own a single book. The only way to access knowledge was to consult their memory.  But technology – from paper to hard drives – has permitted us to free our brains from remembering countless facts. Alphabetization and the simple filing cabinet have helped to systematize and save information we might need someday. But now that we can Google just about any subject, have we lost the ability to memorize information? Does this make our brains better or worse? Guests: Judith Flanders – Historian and author, most recently of A Place for Everything: The Curious History of Alphabetical Order Craig Robertson – Professor of Media Studies, Northeastern University and author of The Filing Cabinet: A Vertical History of Information David Eagleman – Neuroscientist and author, Stanford University Originally aired October 11, 2021 Featuring music by Dewey Dellay and Jun Miyake Big Picture Science is part of the Airwave Media podcast network. Please contact sales@advertisecast.c

The Supreme Court’s ruling on Roe has ignited fierce debate about bodily autonomy. But it’s remarkable how little we know about female physiology. Find out what studies have been overlooked by science, and what has been recently learned. Plus, why studying women’s bodies means being able to say words like “vagina” without shame ... a researcher who is recreating a uterus in her lab to study endometriosis … and an overdue recognition of medical pioneer Dr. Rebecca Lee Crumpler. Guests: Melody T. McCloud - Obstetrician Gynecologist and Founder and Medical Director of Atlanta Women's Health Care; co-author of “Black Women's Wellness: Your ‘I've Got This!’ Guide to Health, Sex, and Phenomenal Living” Victoria Gall - Volunteer with the Friends of the Hyde Park Library and the Hyde Park Historical Society Rachel E. Gross - Science journalist and author of “Vagina Obscura: An Anatomical Voyage” Linda Griffith - Professor of Biological and Mechanical Engineering at M.I.T., Director of the Center for Gynepathology Res

When a Google software engineer claimed that a piece of chatbot software was sentient, it was a major story. Just like your dog is sentient, could it be that some computer code – a chatbot system called LaMDA – has feelings? But was it truly sentient, or was it pulling algorithmic wool over our eyes? Were we simply being fooled by high-tech mimicry? In this, our regular look at critical thinking: Skeptic Check, we ask what is the evidence that this system is sentient. Also, even A.I. that’s not sentient can still be powerful – and that has serious implications.  Guests: Blake Lemoine – Software engineer and artificial intelligence researcher Oren Etzioni – Emeritus Professor at the University of Washington, and former CEO at the Allen Institute for AI in Seattle Mark Coeckelbergh – Professor of Philosophy of Media and Technology, University of Vienna, and author of “Robot Ethics“ Featuring music by Dewey Dellay and Jun Miyake *Free 1-Year NordVPN Subscription* Click the link and enter the code to activate yo

T-Rex is having an identity crisis. Rocking the world of paleontology is the claim that Rex was not one species, but actually three. It’s not the first time that this particular dino has forced us to revise our understanding of the past. The discovery of the first T-Rex fossil in the 19th century taught humanity a scary lesson: species eventually go extinct. If it happened to this seemingly invincible apex predator, it could happen to us too. Hear how the amateur fossil hunter Barnum Brown’s discovery of T-Rex changed our understanding of ourselves, and the epilogue to the dinosaur era: how our mammalian relatives survived the potential extinction bottleneck of an asteroid impact. Guests: Thomas Carr - Vertebrate paleontologist and Professor of Biology, Carthage College Peter Makovicky - Vertebrate paleontologist and Professor of paleontology in the Department of Earth and Environmental Sciences at the University of Minnesota David Randall - Author of “The Monster’s Bones: The Discovery of T Rex and How It Sh

They’re cute and cuddly. But they can also be obnoxious. Science writer Mary Roach has numerous tales about how our animal friends don’t always bow to their human overlords and behave the way we’d want. The resulting encounters, such as when gulls disrupt the Vatican’s Easter mass, make for amusing stories. But others, such as wolves threatening farmers’ livestock, can be tragic. We hear what happens at the messy crossroads of human and wildlife encounters. Guest: Mary Roach – Author of bestselling nonfiction books, most recently “Fuzz: When Nature Breaks the Law.” Originally aired September 13, 2021 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.

It was a radical idea a century ago, when Einstein said space and time can be bent, and gravity was really geometry. We hear how his theories inspire young minds even today. At small scales, different rules apply: quantum mechanics and the Standard Model for particles. New experiments suggest that muons – cousins of the electron – may be telling us that the Standard Model is wrong. Also, where the physics of both the large and small apply, and why black holes have no hair. Guests: Hakeem Oluseyi – Astrophysicist, affiliated professor at George Mason University, and author of “A Quantum Life: My Unlikely Journey from the Street to the Stars” Janna Levin – Professor of physics and astronomy, Barnard College at Columbia University Mark Lancaster – Professor of particle physics, University of Manchester Originally aired August 16, 2021 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 adve

Sexist snow plowing? Data that guide everything from snow removal schedules to heart research often fail to consider gender. In these cases, “reference man” stands in for “average human.” Human bias also infects artificial intelligence, with speech recognition triggered only by male voices and facial recognition that can’t see black faces. We question the assumptions baked into these numbers and algorithms. Guests: Caroline Criado-Perez - Journalist and author of “Invisible Women: Data Bias in a World Designed for Men” Kade Crockford - Director of the Technology for Liberty Program at the ACLU of Massachusetts Amy Webb - Futurist, founder and CEO of the Future Today Institute, and author of “The Big Nine: How the Tech Titans and There Thinking Machines Could Warp Humanity” Originally aired September 2, 2019 Featuring opening theme by 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.  

Above the Arctic Circle, much of the land is underlaid by permafrost. But climate change is causing it to thaw. This is not good news for the planet.  As the carbon rich ground warms, microbes start to feast… releasing greenhouse gases that will warm the Earth even more. Another possible downside was envisioned by a science-fiction author. Could ancient pathogens–released from the permafrost’s icy grip–cause new pandemics? We investigate what happens when the far north defrosts. Guests: Jacquelyn Gill – Associate professor of paleoecology at the University of Maine. Jim Shepard – Novelist and short story writer, and teacher of English at Williams College, and author of “Phase Six.” Scott Saleska – Global change ecologist, professor of Ecology and Evolutionary Biology at the University of Arizona, and co-founder of IsoGenie.

Every second, lightning strikes 50 to 100 times somewhere. It can wreak havoc by starting wildfires and sometimes killing people. But lightning also produces a form of nitrogen that’s essential to vegetation. In this episode, we talk about the nature of these dramatic sparks. Ben Franklin established their electric origin, so what do we still not know? Also, why the frequency of lightning strikes is increasing in some parts of the world. And, what to do if you find someone hit by lightning. Guests: Thomas Yeadaker – Resident of Oakland, California Chris Davis – Medical doctor and Assistant Professor of Emergency Medicine at Wake Forest University and Medical Director for the National Center for Outdoor Adventure Education Jonathan Martin – Professor of Atmospheric and Oceanic Sciences, University of Wisconsin, Madison Steve Ackerman – Professor of Atmospheric and Oceanic Sciences, University of Wisconsin, Madison Peter Bieniek – Professor of Atmospheric and Space Science, University of Alaska, Fairbanks Featu

Animals experience the world differently. There are insects that can see ultraviolet light, while some snakes can hunt in the dark thanks to their ability to sense infrared. Such differences are not restricted to vision: Elephants can hear subsonic sounds, birds navigate by magnetism, and your dog lives in a world marked by odors. In this episode, we speak to science journalist Ed Yong about how other creatures sense the world. Could we ever understand what it’s like to have the hearing of a bat or the sight of a hawk?  Guest: Ed Yong – Science writer for The Atlantic whose coverage of the COVID-19 pandemic earned him a Pulitzer Prize in explanatory journalism. He is the author of, “An Immense World: How Animal Senses Reveal the Hidden Realms Around Us.”  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.   Learn more about your ad choices.

Do we still need doctors? There are umpteen alternative sources of medical advice, including endless and heartfelt health tips from people without medical degrees. Frankly, self-diagnosis with a health app is easier and cheaper than a trip to a clinic. Since we’re urged to be our own health advocate and seek second opinions, why not ask Alexa or consult with a celebrity about what ails us? Find out if you can trust these alternative medical advice platforms. Plus, lessons from an AIDS fighter about ignoring the findings of medical science.   And, if AI can diagnose better than an MD, will we stop listening to doctors altogether? It’s our monthly look at critical thinking … but don’t take our word for it! Guests: Katherine Foley – Science and health reporter at Quartz, and author of the article “Alexa is a Terrible Doctor” Paul Offit – Professor of pediatrics at the Children’s Hospital of Philadelphia and the Perlman School of Medicine at the University of Pennsylvania, and author of “Bad Advice: Or Why Ce

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 A special offer to Big Picture Science listeners: Receive 60% off the first month of a MEL Physics, ME

Your shower pipes are alive. So are your sinks, books, and floorboards. New studies of our homes are revealing just what species live there – in the thousands, from bacteria to flies to millipedes. Meanwhile, life keeps surprising us by popping up in other unexpected places: the deep biosphere houses the majority of the world’s bacteria and the Arctic tundra has kept worms frozen, but alive, for 40,000 years. We embrace the multitude of life living on us, in us, and – as it turns out – in every possible ecological niche. Most of it is harmless, some is beneficial, and it’s all testament to the amazing diversity and adaptability of life. In addition, the hardiest organisms suggest where we might find life beyond Earth. Guests: Rob Dunn – Professor of applied ecology at North Carolina State University and at the Natural History Museum at the University of Copenhagen. Author of “Never Home Alone: From Microbes to Millipedes, Camel Crickets, and Honeybees, the Natural History of Where We Live.” Lynn Rothschil

The James Webb Space Telescope has turned its golden eye on the cosmos. The largest, most sensitive telescope put in space since the Hubble Space Telescope is already producing new photos of far-off galaxies and other cosmic phenomena. In this episode: astronomers share their reactions to these stunning images, the project scientist on JWST describes how infrared cameras capture phenomena that are invisible to shorter wavelengths, and a plan to investigate the very stardust that created everything, including you and me. Guests: Néstor Espinoza – Assistant astronomer, Space Telescope Science Institute, principal investigator for exoplanet atmospheric physics, James Webb Space Telescope Alyssa Pagan – Science Visuals Developer at the Space Telescope Science Institute John Mather – Nobel Prize-winning NASA astronomer and Senior Project Scientist for the James Webb Space Telescope Alex Filippenko – Professor of Astronomy at the University of California, Berkeley Featuring music by Dewey Dellay and Jun Miyake A sp

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 Big Picture Science is part of the Airwave Media podcast network. Please contact sales@advertisecast.com to inquire about advertising on Big Picture Science.

One of the many shocking aspects of the Capitol attack was that it revealed how thoroughly the nation had cleaved into alternate realities. How did we get to this point? How did misinformation come to create beliefs embraced by millions?  In this episode, experts in social media, cults, and the history of science join us for a discussion about how these alternative realities formed, why people are drawn to them, and the benefits of a shared reality.  Guests: Joan Donovan – Research Director of the Shorenstein Center on Media, Politics and Public Policy in the John F. Kennedy School of Government at Harvard University, and leader of the Technology and Social Change Project. Lee McIntyre – Research fellow at the Center for Philosophy and History of Science at Boston University, Instructor in Ethics at Harvard Extension School, and author of “Post – Truth.” Steven Hassan – Mental health counselor who has written on the subject of mind control. Former member of the Unification Church, and author of “The Cu

Are you ready to defer all your personal decision-making to machines? Polls show that most Americans are uneasy about the unchecked growth of artificial intelligence. The possible misuse of genetic engineering also makes us anxious. We all have a stake in the responsible development of science and technology, but fortunately, science fiction films can help. The movies Ex Machina and Jurassic Park suggest where A.I. and unfettered gene-tinkering could lead. But even less popular sci-fi movies can help us imagine unsettling scenarios regarding over-population, smart drugs, and human cloning.  And not all tales are grim. The 1951 film, The Man in the White Suit, weaves a humorous story of materials science run amok.   So, grab a bowl of popcorn and join us in contemplating the future of humanity as Hollywood sees it! Guest: Andrew Maynard – Physicist and professor at the School for the Future of Innovation in Society at Arizona State University, and author of Films from the Future: The Technology and Morality o

The toilet: A ubiquitous appliance that dates to the time of Shakespeare. But billions of people around the world still lack modern sanitation infrastructure. And the incentive to modernize includes the possibility that recycling human waste could help with conservation efforts, energy generation, and even medicine. Also, a sixth-grader puts lipstick on cats’ bottoms to map places their tush has touched, and in Michigan, why peeing on the peonies can be a good thing. Guests: Kaeden Henry – Sixth grade student in Tennessee. Kerry Griffin – Mother of Kaeden Henry; holds a doctorate in animal behavior. Yvette Johnson-Walker – Clinical Instructor in Veterinary Clinical Medicine, University of Illinois at Urbana-Champaign. Chelsea Wald – Science and environmental journalist, and author of Pipe Dreams: The Urgent Global Quest to Transform the Toilet.

Standing on your own two feet isn’t easy. While many animals can momentarily balance on their hind legs, we’re the only critters, besides birds, for whom bipedalism is completely normal. Find out why, even though other animals are faster, we’re champions at getting around. Could it be that our upright stance made us human? Plus, why arches help stiffen feet, the argument for bare-footin’, and 12,000-year old footprints that tell a story about an Ice Age mother, her child, and a sloth.  Guests: Daniel Lieberman – Professor of human evolutionary biology at Harvard University. Jeremy DeSilva – Professor in the departments of anthropology and biological sciences, Dartmouth College, and author of “First Steps: How Upright Walking Made Us Human.” Madhusudhan Venkadesan – Professor of mechanical engineering and materials science, Yale University School of Engineering. David Bustos – Chief of Resources at White Sands, National Park, New Mexico. Sally Reynolds – Paleontologist at Bournemouth University, U.K.

You are getting sleeeepy and open to suggestion. But is that how hypnotism works? And does it really open up a portal to the unconscious mind? Hypnotism can be an effective therapeutic tool, and some scientists suggest replacing opioids with hypnosis for pain relief. And yet, the performance aspect of hypnotism often seems at odds with the idea of it being an effective treatment.  In our regular look at critical thinking, Skeptic Check, we ask what part of hypnotism is real and what is an illusion. Plus, we discuss how the swinging watch became hypnotism’s irksome trademark. Guests: David Spiegel – Professor of Psychiatry and Behavioral Sciences at the Stanford University School of Medicine Devin Terhune – Reader in the Department of Psychology, Goldsmiths University of London Featuring music by Dewey Dellay and Jun Miyake Graphic by Shannon Rose Geary Big Picture Science is part of the Airwave Media podcast network. Please contact sales@advertisecast.com to inquire about advertising on Big Picture Science.
