Stanley N. Cohen, pioneering geneticist who helped create plasmid-based cloning. He discusses the lab breakthroughs that made cloning routine. Short scenes cover growing ethical alarm, calls to pause risky recombinant DNA work, and the lead-up to the historic Asilomar meeting. The conversation traces how scientists confronted the social stakes of powerful new techniques.

Check out our new season, dropping weekly on Tuesdays, starting August 5th.

Joining the discussion are Janet Poppendick, a retired professor and author focused on school food reform, and Jane Black, an insightful food journalist. They delve into the intriguing history of school lunches, exploring how crises like the Great Depression shaped nutritional policies. Discover the contradictory hunger amidst agricultural surpluses and the evolution of the National School Lunch Program. They also advocate for universal free school meals as a means to enhance student engagement and combat stigma in food quality.

ALS is a fatal neurological disease that kills motor neurons. Even though it was first described more than 150 years ago, there is no cure, and the few drugs available only dampen the symptoms or slow the progression by a few months. In recent years new drugs have emerged. However, there is one problem: the life expectancy is just two to five years after diagnosis. This timeline is incompatible with the FDA drug approval process, which takes years and even decades. This has created a tense situation for desperate patients who are demanding the FDA approve unproven drugs. What's the harm in giving desperate patients an imperfect drug?

Bill Underwood, a former psychology grad student who went undercover in Rosenhan's study, and Susanna Cahalan, investigative journalist and author, unpack the controversial 1973 study by David Rosenhan, a Stanford psychologist. They discuss how the fake-patient experiment was conducted, the missing and altered records Cahalan uncovered, and the study's sweeping impact on psychiatric diagnosis.

For more than 100 years, biologists who suggested that some cancers may be caused by viruses were the pariahs of genetics. However, they persevered and incrementally built their knowledge, leading to the discovery of retroviruses, the development of a test to diagnose HIV, and the creation of the HPV vaccine. Join us as we interview Gregory J. Morgan about his book Cancer Virus Hunters: A History of Tumor Virology.

In 1973 biochemist Bruce Ames created a simple test that showed if chemicals had the potential to cause cancer. The Ames test made him a hero of the emerging environmental movement. But then he completely changed course and said concerns about chemicals were overblown. So what happened? Did Ames change? Or did our understanding of what causes cancer change? Featured Oral History Bruce N. Ames, "Bruce N. Ames: The Marriage of Biochemistry and Genetics at Caltech, the NIH, UC Berkeley, and CHORI, 1954–2018" conducted by Paul Burnett in 2019 and 2020, Oral History Center, The Bancroft Library, University of California, Berkeley, 2021.

Ozempic and others in this family of drugs are nothing short of miraculous. Meant to treat Type 2 Diabetes, the drug exploded in popularity after researchers found that patients were reporting losing 15-21% of their body weight in clinical trials. There were some side effects, but none so severe that it raised concerns. Doctors began prescribing it to people who weren't diabetic but could benefit from weight loss, and now, our only problem seems to be getting enough of it for all the people who need it. It all seems magical, but is it too good to be true? Join us as we dive into the history of weight loss drugs, drug manufacturing regulations, and the role we think medicine should play in our lives.

The impact of cars on wildlife extends beyond roadkill, affecting species that never venture near roads. Car noise disrupts bird communication and behavior, and tire and brake dust from pollutes waterways with microplastics. In this wide-ranging interview, we talk to the author of Traffication: How Cars Destroy Nature and What We Can Do About It, Paul Donald about how he coined the term "traffication," the history of road ecology, and what we can do about the problem.

Andrew Scull, sociologist and author of Desperate Remedies, offers historical and sociological perspective on psychiatry and antipsychotic drugs. The conversation traces mauve’s accidental birth from a failed quinine synthesis and how dyes led to drugs like Thorazine. It highlights surgical uses, institutional impacts, side effects, and the role of serendipity in drug discovery.
