In 1994, while attending graduate school at the University of California, Berkeley, I had the pleasure of seeing a lecture by Oliver Sacks in which he discussed his work on sleeping sickness and various other neurological disorders. He also discussed his thoughts on the economy of a life. Today's episode is that lecture in full, with all the insights and charm that was Oliver Sacks ..read more

Novichok is the most deadly chemical weapon ever developed. With us to discuss the history of Novichok is Vil Mirzayanov. Vil worked in the secret Soviet chemical weapons laboratory that developed Novichok. He revealed its existence to the world in 1991 and was then arrested by the Russian counterintelligence service and prosecuted in a secret trial. He won his freedom with the help of an international group of scientists, including three who have appeared as guests on this podcast. He then immigrated to the United States and published his story in the book State Secrets. An Insider's Chronicl ..read more

How could a brilliant scientist and mathematician, an innovator in quantum theory, who worked closely with Jewish colleagues, become an ardent Nazi? How did this man, who has a field of mathematics named after him, escape the scrutiny of his colleagues? And what happened to him upon the collapse of Nazi Germany? The scientist who straddled this strange world of physics and Nazism was Pascual Jordan. With us to explain the history of Pascual Jordan is Ryan Dahn. Ryan is a writer, editor, science historian, and translator. He is the books editor at Physics Today, the flagship physics magazine of ..read more

The ability to extract DNA from ancient fragments of biological material has revolutionized our understanding of recent evolutionary history, including human evolution and phylogeography. Analysis of ancient DNA in tandem with radiocarbon dating, along with traditional archeological techniques, has led to a flurry of discoveries. With us to discuss this research is Maanasa Raghavan. Maanasa is a Neubauer Family Assistant Professor of Human Genetics at the University of Chicago.  ..read more

The world just experienced a devastating pandemic, yet in the context of historical pandemics, COVID-19 was a relatively minor event in the history of disease.
