The World as You’ll Know It: The Great Rebuild

The United States was once on track to be a world leader in nuclear power, building more than 100 plants in the 1970s and 1980s. But cost and safety concerns led to decades of decommissioning old plants and canceling plans to build new ones. Now, with clean energy production a top priority, there are signs of a revival. Reactors at the first new nuclear plant to be built in almost 30 years went online last year, and the Biden administration wants to triple the country’s nuclear capacity. Host Arielle Duhaime-Ross discusses the hurdles facing nuclear power, as well as a new vision for smaller, more adaptable reactors with Dr. Kathryn Huff, former assistant secretary for the Office of Nuclear Energy; historian and Pulitzer-Prize winning author Richard Rhodes; and the undergraduates – that’s right, undergraduates – who run their own nuclear reactor.

Americans drive more, drive further, and pay less for fuel than people in other developed countries. Partly for this reason, our vehicles are more than just a means of transportation — they’re extensions of who we are. So persuading Americans to swap out gas-dependent cars for EVs is a different — and in many ways more difficult — challenge. What’s it going to take to get more Americans into electric vehicles? Host Arielle Duhaime-Ross explores the obstacles and possible solutions to EV adoption with guests David Ferris, a reporter covering transportation and energy for E&E News and Politico; Joseph Barletta, the founder and CEO of Smart Charge America, a company that installs EV chargers; and Dr. Linda Nazar, an expert in battery chemistry and professor of chemistry at the University of Waterloo.

In the past 50 years, solar energy has surpassed all expectations. Even early solar experts couldn’t predict how affordable and widespread it would become. The story behind its success involves Einstein, US presidents, obscure legislation and a global relay race. Now the question is – What can the rise of solar power teach us about the future of other climate technologies? Join this season’s host, Arielle Duhaime-Ross, in conversations with Greg Nemet, author of “How Solar Became Cheap,” and Nathanael Greene, from the National Resources Defense Council, to discuss today’s solar landscape, its future potential, and the challenges we face in getting there.

Misinformation has already influenced our elections, ruined reputations and fundamentally changed society’s relationship with the truth. Now, large language models like GPT have the potential to create and spread misinformation at a speed and scale we’ve never seen before. As new technologies allow bad actors to imitate the way we write, the way we speak and the way we appear in photos and videos, the question won’t be, ‘What we can believe in?’ but whether we’ll be able to believe in anything at all. To discuss how we got here and what we must do to fix it, host Gary Marcus talks to Pranshu Verma and Will Oremus, two technology writers from the Washington Post, and Dr. Rumman Chowdhury, a leading expert in Ethical AI and former Director of the Ethics and Transparency team at Twitter.

One out of five Americans suffer from chronic pain and a new approach to treatment could transform their lives. Judith Warner speaks with Drs. Yoni Ashar and Tor Wager, neuroscientists who are at the forefront of a new way to understand and treat chronic pain that looks to the brain rather than the body as pain’s source. The treatment is relatively new, but growing rapidly in acceptance, thanks in part to a groundbreaking study published in the Journal of the American Medical Association earlier this year in which two-thirds of participants who were treated with the new approach were pain free or nearly pain free after a month. DR. ASHAR is a clinical psychologist and an assistant professor at the University of Colorado Anschutz medical campus; DR. WAGER is a neuroscientist and a professor at Dartmouth.
