Entanglements, by Undark

It's the final episode of Season 3! And possibly our last episode for awhile. This week, our hosts discuss the podcast and science journalism with Undark editor-in-chief Tom Zeller Jr. and, for now anyway, bid adieu to listeners.

This week on Entanglements: Is there really a population crisis? To answer what seems like a simple question, our hosts talk to an economist and a demographer about the world population trends and fertility rates.

This week on Entanglements: Are octopuses conscious? What about lobsters? Or mosquitoes? Our hosts talk to two philosophers — one at the University of Southampton in the U.K, another is the director of the Critical Thinking Project at the University of Queensland in Australia — about which animals are sentient, and why.

This week on Entanglements: Is ADHD a disorder? The symptoms are certainly real, but scientists are not in agreement whether or not to call ADHD a true disorder. Our hosts dig in with a professor of molecular psychiatry at Radboud University in the Netherlands and a developmental psychologist and professor at King's College London.

We're back again! This week on Entanglements: Should we allow AI technology to be put in our brains? It sounds like something out of science fiction, but our hosts discuss the current research on neural implants with a professor of neurology and neuroethics at the University of British Columbia and a physician scientist and medical ethicist at Weill Cornell Medicine in New York.

In the Season 2 finale, our hosts talk to Tom Zeller Jr., Undark’s editor-in-chief, about covering science under the Trump administration. While the podcast's topics are always politically charged, they have become even more so in the current political climate.

This week on Entanglements: Do we have enough scientific evidence to approve psychedelics as medicine? Our hosts unpack the data with Albert Garcia-Romeu, an associate professor of psychiatry and behavioral sciences at Johns Hopkins School of Medicine, and Bertha Madras, a professor of psychobiology at Harvard Medical School.

This week on Entanglements: Should we live on Mars, and beyond? Our hosts talk to Tiffany Vora, a biologist and space advocate who has done three analog Mars simulations, and Kelly Weinersmith, a biologist and the co-author of the book “A City on Mars."

This week on Entanglements: Should tech companies — and the billionaires that often run them — decide for the rest of us how artificial intelligence is deployed? Our hosts dig into the topic with two book authors who have covered AI from essentially opposing perspectives: Greg Beato and Adam Becker.

This week on Entanglements: Should we switch all U.S. elections to ranked choice voting? Our hosts discuss the pros and cons with Deb Otis, director of research and policy for Fair Vote, a non-profit that works on election reform, and David McCune, a professor of mathematics at William Jewell College in Missouri.
