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.

You interact with about two-thirds of the elements of the periodic table every day. Some, like carbon, oxygen, and nitrogen, make up our bodies and the air we breathe. Yet there is also a class of elements so unstable they can only be made in a lab. These superheavy elements are the purview of a small group stretching the boundaries of chemistry. Can they extend the periodic table beyond the 118 in it now? Find out scientists are using particle accelerators to create element 120 and why they’ve skipped over element 119. Plus, if an element exists for only a fraction of a second in the lab, can we still say that counts as existing?

Guests:

Mark Miodownik – professor of materials and society at the University of College London and the author of “It’s a Gas: The Sublime and Elusive Elements That Expand Our World.”

Kit Chapman – Science historian at Falmouth University, author of “Superheavy; Making and Breaking the Periodic Table.”

Science fiction movies force us to face a multitude of end-of-the-world scenarios. Whether the final curtain is dropped by rampaging aliens, killer rocks from space, or virus-infected zombies, these big screen glimpses of a dystopian future are as tantalizing as they are frightening. But one American city seems to be a favorite backdrop for stories of mass destruction. We speak with a cultural critic about why New York City is often the chosen setting for disaster films, and what dystopian fiction reveals about our shifting anxieties about humanity’s future no matter where we live.

Movies discussed include Deep Impact, Escape from New York, Planet of the Apes, King Kong, Cloverfield, Deluge, Failsafe, The Day After Tomorrow, AI: Artificial Intelligence, Contagion, I Am Legend, and Seth’s very own short film: The Turkey that Ate St. Louis

While humans were leaving the Stone Age and entering the Bronze, some Bristlecone pine trees grew from seeds to sprouts. They’ve been growing ever since. These 5,000-year-old pines are among the oldest organisms on Earth. Superlatives are also appropriate for the towering redwoods.

Trees are amazing in many ways. They provide us with timber and cool us with shade, they sequester carbon and release oxygen, and are home to countless species. But they are also marvels of evolutionary adaptation. We consider the beauty and diversity of trees, and learn why their future is intertwined with ours.

Just because something is invisible doesn’t mean it isn’t there. We can’t see gases in our atmosphere, such as carbon dioxide, oxygen, and nitrogen, but we benefit from their presence with every breath we take. From the bubbles that effervesce in soda to the vapors that turn engines, gases are part of our lives. They fill our lungs, give birth to stars, and… well, how would we spot a good diner without glowing neon? In this episode, a materials scientist shares the history of some gaseous substances that we don’t usually see, but that make up our world.

Mark Miodownik – Professor of materials and society at the University College London and the author of “It’s a Gas: The Sublime and Elusive Elements That Expand Our World.”

The Amazon is often described as an ecosystem under dire threat due to climate change and deliberate deforestation. Yet there is still considerable hope that these threats can be mitigated.  In the face of these threats, indigenous conservationists are attempting to strike a balance between tradition and preserving Amazonia.  Meanwhile, two river journeys more than 100 years apart – one by a contemporary National Geographic reporter and another by “The Lewis and Clark of Brazil”— draw attention to the beauty and diversity of one of the world’s most important ecosystems.

Guests:

Cynthia Gorney – Contributing writer at the National Geographic Society, former bureau chief for South America at The Washington Post

Larry Rohter – Reporter and correspondent in Rio de Janeiro for fourteen years for Newsweek and as The New York Times bureau chief. Author of Into the Amazon: The Life of Cândido Rondon, Trailblazing Explorer, Scientist, Statesman, and Conservationist

João Campos-Silva – Brazilian researcher and conservationist, and cofounder of Instituto Jura, a conservation organization.  His work, along with that of other conservationists, is featured in the National Geographic issue devoted to the Amazon.

The worry about whether H5N1 will trigger a human pandemic has concealed a startling reality. Avian influenza has already taken an enormous toll on the lives of other animals. Since 2005, the number of wild and domesticated birds killed is greater than the combined human populations of the United States and Russia. Bird flu is burning through wild flocks, poultry farms, and mammal populations, including those of sea mammals. We look at the places where the virus can recombine and mutate, and why this version is not simply dying out as it has in years past. At a squawking live poultry market in Brooklyn, and on a Long Island duck farm, we hear about the difficult experience of euthanizing 100,000 birds and whether a farm can recover from such a devastating loss. And finally, we ask, why poultry vaccines that could curb the spread of H5N1 aren’t being used. But we begin our episode with descriptions of the soaring global migrations of birds whose feats of endurance help us understand why H5N1 is widespread in birds worldwide.

Guests:

Scott Weidensaul – Ornithologist, bird migration researcher, and author of "A World on the Wing: The Global Odyssey of Migratory Birds"

David Swayne – Bird flu veterinarian

Doug Corwin – Farmer and owner of Crescent Duck Farm, Aquebogue, New York

Jon Cohen – Senior correspondent with Science Magazine, where you can find his recent article, “The Pandemic Next Time,” and author of "Planning Miracles: How to Prevent Future Pandemics"

The idea that the universe is made of tiny vibrating strings was once the science theory du jour. String theory promised to unite the disparate theories describing particles and gravity, and many people, not just scientists, were optimistic that a theory of everything might be within our grasp. But here we are, many years later, and string theory doesn’t seem to have delivered on its initial promise. What happened? We consider the science around string theory in this episode of Skeptic Check.

Guest:

Brian Greene – Physicist and mathematician at Columbia University, and author of The Elegant Universe: Superstrings, Hidden Dimensions, and the Quest for the Ultimate Theory.

In Brazil, leaders from across the globe are gathering for COP30, the premier climate summit in the world. For the first time, the U.S. is sitting it out, after exiting the Paris Agreement. There is, however, a ray of hope in the global efforts to reduce fossil fuel emissions. Bill McKibben, an environmentalist and journalist who describes himself as a “professional bummer-out-of-people,” has good news about the solar energy industry, after years of his repeated, and alarming, reports about our failure to address climate change. For the first time ever, solar energy production is outpacing the fossil fuel industry. Momentum is gathering in surprising places. The state with the fastest growing clean energy sector is the oil and gas country, Texas. And, when energy analysts investigated Pakistan’s sudden drop in energy demand, they saw “solar panels spreading across rooftops like mushrooms after a rainstorm.”

Guests:

Bill McKibben – environmentalist, journalist and author of “Here Comes the Sun: A Last Chance for the Climate and a Fresh Chance for Civilization” 

Jon Gertner – journalist, editor, and author of “The Idea Factory: Bell Labs and the Great Age of American Innovation”

“The Mississippi River will always have its own way; no engineering skill can persuade it to do otherwise,” said Mark Twain. In this, our final episode marking the 20th anniversary of Hurricane Katrina, we consider how efforts to control the Mighty Mississippi – a river engineered from its Minnesota headwaters to its Gulf Coast outlet – have responded to the devastating storm, and how New Orleans’ relationship to the river has changed. Can the city keep up with the pressure that climate change is putting on this engineered system, or is retreat the only viable response?

Plus, a wetland recovery project that aims to bolster protection from hurricanes and flooding in the Lower Ninth Ward.

Guests:

Boyce Upholt – Journalist and author of “The Great River: The Making and Unmaking of the Mississippi River” 

Nathaniel Rich – Author of “Second Nature: Scenes From a World Remade” and the New York Times Op-Ed, “New Orleans’ Striking Advantage in the Age of Climate Change” 

Harriet Swift – New Orleans resident

Andrew Horowitz – Historian, University of Connecticut, author of "Katrina: A History, 1915-2015"
