Investigative journalist Charles Piller joins host Sarah Crespi to discuss his latest Science exclusive: a deep dive into the Food and Drug Administration’s protection of human subjects in clinical trials. Based on months of data analysis and interviews, he uncovered long-term failures in safety enforcement in clinical trials and potential problems with trial data used to make decisions about drug and device approvals. Sarah also talks with Klaus-Robert Müller, a professor of machine learning at the Technical University of Berlin, about an artificial intelligence (AI) trained in the sport of curling—often described as a cross between bowling and chess. Although AI has succeeded in chess, Go, and poker, the constantly changing environment of curling is far harder for a nonhuman mind to adapt to. But AIs were the big winners in competitions with top human players, Müller and colleagues report this week in Science Robotics. This week’s episode was produced with help from Podigy.

Contributing Correspondent Ann Gibbons talks with host Sarah Crespi about a series of 120,000-year-old human footprints found alongside prints from animals like asses, elephants, and camels in a dried-up lake on the Arabian Peninsula. These are the earliest human footprints found so far in Arabia and may help researchers better understand the history of early hominin migrations out of Africa. Continuing on the history of humanity theme, Sarah talks with Janet Kelso of the Max Planck Institute for Evolutionary Anthropology, about her team’s efforts to fish the elusive Y chromosome out of Neanderthal and Denisovan DNA. It turns out Y chromosomes tell a different story about our past interbreeding with Neanderthals than previous tales told by the rest of the genome. Read a related Insight article.

Staff Writer Kelly Servick joins host Sarah Crespi to discuss how jail and prison populations in the United States have dropped in the face of coronavirus and what kinds of scientific questions about public health and criminal justice are arising as a result. Also this week, Elias García-Pelegrín, a Ph.D. student at the University of Cambridge, talks with Sarah about his article on watching animals watch magic tricks. Do animals fall for the same illusions we do? What does it say about the way their minds work? This week’s episode was produced with help from Podigy. Listen to previous podcasts.
