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

With planets and moons, it’s what’s inside that counts. If we want to understand surface features, like volcanoes, or their history, such as how the planet formed or whether it’s suitable for life, we study their interiors. Astronomer Sabine Stanley takes us on a journey to the centers of Venus, Saturn’s large moon Titan, Jupiter’s moon Io, and of course Earth, to help us understand how they, and the solar system, came to be. 

Guest:

Sabine Stanley - Planetary scientist at Johns Hopkins University and the author of What’s Hidden Inside Planets.

Worried that AI will replace you? It may not seem like the Hollywood writers’ strike has anything in common with the Luddite rebellion in England in 1811, but they are surprisingly similar. Today we use the term “Luddite” dismissively to describe a technophobe, but the original Luddites – cloth workers – organized and fought Industrial Revolution automation and the factory bosses who were replacing humans with cotton spinning machines and steam powered looms. Find out what our age of AI can learn from textile workers of 200 years ago about keeping humans in the loop.

By one estimate we spend a fifth of our lives watching movies or TV. In fact, we consume entertainment almost as habitually as we eat or sleep, activities that receive scientific scrutiny and study. So why not consider the effects that watching movies and TV have on our minds and bodies too? When we do, we find that they are not mere escapism. A data scientist reveals why we are what we watch, and how scientists and filmmakers work, often with competing agendas, to create sci-fi entertainment.

Guest:

Walt Hickey - journalist, data scientist, and author of “You Are What You Watch: How Movies and TV Affect Everything”

Maybe you don’t remember the days of the earliest coal-fired stoves. They changed domestic life, and that changed society. We take you back to that era, and to millennia prior when iron was first smelt, and even earlier, when axe-handles were first fashioned from wood, as we explore how three essential materials profoundly transformed society. 

We were once excited about coal’s promise to provide cheap energy, and how iron would lead to indestructible bridges, ships, and buildings. But they also caused some unintended problems: destruction of forests, greenhouse gases and corrosion. Did we foresee where the use of wood, coal, and iron would lead? What lessons do they offer for our future?

Guests:

Jonathan Waldman – Author of Rust: The Longest War.

Ruth Goodman – Historian of British social customs, presenter of a number of BBC television series, including Tudor Monastery Farm, and the author of The Domestic Revolution: How the Introduction of Coal into Victorian Homes Changed Everything.

Roland Ennos – Professor of biological sciences at the University of Hull and author of The Age of Wood: Our Most Useful Material and the Construction of Civilization.

After helping to sequence the human genome more than twenty years ago, biochemist Craig Venter seemed to recede from the public eye. But he hadn’t retired. He had gone to sea and taken his revolutionary sequencing tools with him. We chatted with him about his multi-year voyage aboard the research vessel Sorcerer II, its parallels to Darwin’s voyage, and the surprising discoveries his team made about the sheer number and diversity of marine microbes and their roles in ocean ecosystems.

Guests:

Craig Venter - Genomicist, biochemist, founder of the J. Craig Venter Institute, and co-author of “The Voyage of Sorcerer II: The Expedition that Unlocked the Secrets of the Ocean’s Microbiome.”

Jeff Hoffman - Lab manager at the J. Craig Venter Institute and expedition scientist on the Sorcerer II expedition.

Our information age is increasingly the disinformation age. The spread of lies and conspiracy theories has created competing experiences of reality. Facts are often useless for changing minds or even making compelling arguments. In this episode, author Naomi Klein and science philosopher Lee McIntyre discuss why the goal – not simply the byproduct - of spreading disinformation is to polarize society. They also offer ideas about how we might find our way back to a shared objective truth.  

Guests:

Naomi Klein - Associate professor of Geography at the University of British Columbia and a co-director at the Center for Climate Justice. Author of Doppelganger: A Trip Into the Mirror World

Lee McIntyre - Philosopher of science and a research fellow at the Center for Philosophy and the History of Science at Boston University, and author of Post-Truth and On Disinformation.

Nothing lasts forever. Even the universe has several possible endings. Will there be a dramatic Big Rip or a Big Chill­–also known as the heat death of the universe–in trillions of years? Or will vacuum decay, which could theoretically happen at any moment, do us in? Perhaps the death of a tiny particle – the proton – will bring about the end.

We contemplate big picture endings in this episode, and whether one could be brought about by our own machine creations. 

Guests: 

Anders Sandberg – Researcher at

the Future of Humanity Institute at the University of Oxford

Katie Mack – Assistant professor of physics at North Carolina State

University, and the author of “The End of Everything, Astrophysically

Speaking.”

Brian Greene – Brian Greene, professor of physics and mathematics at

Columbia, and author of “Until the End of Time: Mind, Matter, and Our

Search for Meaning in an Evolving Universe”

The world is a colorful place, and human eyes have evolved to take it in – from vermillion red to bright tangerine to cobalt blue. But when we do, are you and I seeing the same thing? 

Find out why color perception is a trick of the brain, and why you and I may not see the same shade of green. Or blue. Or red. Also, platypuses and the growing club of fluorescent mammals, and the first new blue pigment in more than two centuries.  

Guests:

Paula Anich – Associate Professor of Natural Resources, Northland College

Michaela Carlson – Assistant Professor of Chemistry, Northland College

Rob DeSalle – Curator at the American Museum of Natural History, and co-author of “A Natural History of Color: the Science Behind What We See and How We See It”
