Phreaky Physics (rebroadcast)
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

Skeptic Check: Data Bias (rebroadcast)
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”

De-Permafrosting
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.

Like Lightning
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, CaliforniaChris Davis – Medical doctor and Assistant Professor of Emergency Medicine at Wake Forest University and Medical Director for the National Center for Outdoor Adventure EducationJonathan Martin – Professor of Atmospheric and Oceanic Sciences, University of Wisconsin, MadisonSteve Ackerman – Professor of Atmospheric and Oceanic Sciences, University of Wisconsin, MadisonPeter Bieniek – Professor of Atmospheric and Space Science, University of Alaska, FairbanksFeaturing music by Dewey Dellay and Jun MiyakeBig Picture Science is part of the Airwave Media podcast network.

Coming to Our Animal Senses
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 MiyakeBig Picture Science is part of the Airwave Media podcast network.

Skeptic Check: Heal Thyself (rebroadcast)
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 Celebrities, Politicians, and Activists Aren’t Your Best Source of Health Information”

Platypus Crazy (rebroadcast)
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

Rip Van Winkle Worm (rebroadcast)
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 Rothschild – Astrobiologist and synthetic biologist at the NASA Ames Research Center.
Karen Lloyd – Environmental microbiologist and associate professor at the University of Tennessee.

Building a Space Colony
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 controllerEmily St. John Mandel – Author, most recently of “Sea of Tranquility”John Adams – Deputy Director, Biosphere 2, University of ArizonaFeaturing music by Dewey Dellay and Jun MiyakeBig Picture Science is part of the Airwave Media podcast network.
