Extraordinary Ordinary Objects Oct 30, 2023

Show notes

“To live is to count and to count is to calculate.” But before we plugged in the computer to express this ethos, we pulled out the pocket calculator. It became a monarch of mathematics that sparked a computing revolution. But it’s not the only deceptively modest innovation that changed how we work and live. Find out how sewing a scrap of fabric into clothing helped define private life and how adding lines to paper helped build an Empire. Plus, does every invention entail irrevocable cultural loss?

Guests:

Keith Houston – author of “Empire of the Sum: The Rise and Reign of the Pocket Calculator.”

Hannah Carlson – teaches dress history and material culture at the Rhode Island School of Design, author of “Pockets: An Intimate History of How We Keep Things Close.”

Dominic Riley – bookbinder in the U.K.

Like Lightning* Oct 23, 2023

Show notes

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

Skeptic Check: Worrier Mentality* Oct 16, 2023

Show notes

Poisonous snakes, lightning strikes, a rogue rock from space. There are plenty of scary things to fret about, but are we burning adrenaline on the right ones? Stepping into the bathtub is more dangerous than flying from a statistical point of view, but no one signs up for “fear of showering” classes.

Find out why we get tripped up by statistics, worry about the wrong things, and how the “intelligence trap” not only leads smart people to make dumb mistakes, but actually causes them to make more.

Guests:

Eric Chudler – Research associate professor, department of bioengineering, University of Washington, Seattle and co-author of “Worried: Science Investigates Some of Life’s Common Concerns”

Lise Johnson – Director of the Basic Science Curriculum, Rocky Vista University, and co-author of “Worried: Science Investigates Some of Life’s Common Concerns”

Willie Turner – Vice President of Operations at the Hiller Aviation Museum in San Carlos, CA

Charles Wheelan – Senior Lecturer and Policy Fellow, Dartmouth College, and author of “Naked Statistics”

David Robson – Commissioning Editor for the BBC and author of “The Intelligence Trap: Why Smart People Make Dumb Mistakes”

Going Multicellular Oct 09, 2023

Show notes

Imagine life without animals, trees, and fungi. The world would look very different. But while the first life was surely single-celled, we don’t know just how it evolved to multicellular organisms. Two long-term experiments hope to find out, and one has been running for more than 35 years. Hear about the moment scientists watched evolution take off in the lab, and how directed evolution was used to create a multicellular organism. Also, how single embryonic cells become humans, and what all of this says about the possibility of life on other worlds.

Guests:

Jeff Barrick – molecular scientist at the University of Texas at Austin where his lab oversees the Long-Term Evolution Experiment that’s been running since 1988.

Will Ratcliff- an evolutionary biologist at Georgia Institute of Technology

Ben Stanger - cancer researcher, professor of medicine and developmental biology at the University of Pennsylvania and author of “From One Cell: A Journey into Life’s Origins and the Future of Medicine.”

Joseph L. Graves - evolutionary biologist and geneticist at North Carolina Agricultural and Technical State University and author of “A Voice in the Wilderness: A Pioneering Biologist Explains How Evolution Can Help Us Solve Our Biggest Problems.”

How Hot is Too Hot? Oct 02, 2023

Show notes

Extreme heat is taking its toll on the natural world. We use words like “heat domes” and “freakish” to describe our everyday existence. These high temperatures aren’t only uncomfortable - they are lethal to humans, animals, and crops. In search of an answer to our episode’s question, we discuss the dilemma of an ever-hotter world with an author who has covered climate change for more than twenty years.

Guest:

Jeff Goodell – author of “The Heat Will Kill You First: Life and Death on a Scorched Planet.”

Skeptic Check: Near Death Experiences Sep 25, 2023

Show notes

Near death experiences can be profound and even life changing. People describe seeing bright lights, staring into the abyss, or meeting dead relatives. Many believe these experiences to be proof of an afterlife.

But now, scientists are studying these strange events and gaining insights into the brain and consciousness itself. Will we uncover the scientific underpinning of these near-death events?

Guests:

Steve Paulson - executive producer of To the Best of Our Knowledge for Wisconsin Public Radio

Sebastian Junger - journalist, filmmaker and author of “The Perfect Storm: A True Story of Men Against the Sea”

Christoph Koch - neuroscientist at the Allen Institute in Seattle and chief scientist of the Tiny Blue Dot Foundation in Santa Monica California

Daniel Kondziella - neuroscientist in the Department of Clinical Medicine at the University of Copenhagen

Into the Deep* Sep 18, 2023

Show notes

Have you ever heard worms arguing? Deep-sea scientists use hydrophones to eavesdrop on “mouth-fighting worms.” It’s one of the many ways scientists are trying to catalog the diversity of the deep oceans — estimated to be comparable to a rainforest.

But the clock is ticking. While vast expanses of the deep sea are still unexplored, mining companies are ready with dredging vehicles to strip mine the seafloor, potentially destroying rare and vulnerable ecosystems. Are we willing to eradicate an alien landscape that we haven’t yet visited?

Guests:

Craig McClain - deep-sea and evolutionary biologist and ecologist, Executive Director of the Louisiana Universities Marine Consortium.

Steve Haddock- senior scientist at the Monetary Bay Aquarium Research Institute, and co-author of a New York Times op-ed about the dangers of mining.

Emily Hall- marine chemist at the Mote Marine Laboratory, Sarasota, Florida

Chong Chen - deep sea biologist with the Japan Agency for Marine-Earth Science and Technology (JAMSTEC)

What's a Few Degrees? Sep 11, 2023

Show notes

Brace yourself for heatwave “Lucifer.” Dangerous deadly heatwaves may soon be so common that we give them names, just like hurricanes. This is one of the dramatic consequences of just a few degrees rise in average temperatures.

Also coming: Massive heat “blobs” that form in the oceans and damage marine life, and powerful windstorms called “derechos” pummeling the Midwest.

Plus, are fungal pathogens adapting to hotter temperatures and breaching the 98.6 F thermal barrier that keeps them from infecting us?

Guests:

Kathy Baughman McLeod – director and senior vice president of the Adrienne Arsht-Rockefeller Foundation Resilience Center at The Atlantic Council

Pippa Moore – Marine ecologist at Newcastle University in the U.K.

Ted Derouin – Michigan farmer

Jeff Dukes – Ecologist and director of Purdue Climate Change Research Center at Purdue University.

Arturo Casadevall – Molecular microbiologist and immunologist at the Johns Hopkins School of Medicine

Building a Space Colony* Sep 04, 2023

Show notes

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

Talk the Walk* Aug 28, 2023

Show notes

Birds and bees do it … and so do fish. In a discovery that highlights the adaptive benefits of walking, scientists have discovered fish that can walk on land. Not fin-flap their bodies, mind you, but ambulate like reptiles.

And speaking of which, new research shows that T Rex, the biggest reptile of them all, wasn’t a sprinter, but could be an efficient hunter by outwalking its prey.

Find out the advantage of legging it, and how human bipedalism stacks up. Not only is walking good for our bodies and brains, but not walking can change your personality and adversely affect your health.

Guests:

Hans Larsson – Paleontologist and biologist, and Director of the Redpath Museum at McGill University in Montréal.

Shane O’Mara – Neuroscientist and professor of experimental brain research at Trinity College Dublin. He is the author of “In Praise of Walking.”

Brooke Flammang – Biologist at the New Jersey Institute of Technology.
