On this week’s show: How sci-fi writer Kurt Vonnegut foresaw many of today’s ethical dilemmas, and 70 years of tunas, billfishes, and sharks as sentinels of global ocean health First up this week on the podcast, we revisit the works of science fiction author Kurt Vonneugt on what would have been his 100th birthday. News Intern Zack Savitsky and host Sarah Crespi discuss the work of ethicists, philosophers, and Vonnegut scholars on his influence on the ethics and practice of science. Researchers featured in this segment: Peter-Paul Verbeek, a philosopher of science and technology at the University of Amsterdam and chair of the World Commission on the Ethics of Scientific Knowledge and Technology David Koepsell, a philosopher of science and technology at Texas A&M University, College Station Christina Jarvis, a Vonnegut scholar at the State University of New York, Fredonia, and author of the new book Lucky Mud & Other Foma: A Field Guide to Kurt Vonnegut’s Environmentalism and Planetary Citizenship Sheila Jasanoff, a science studies scholar at Harvard University Next, producer Kevin McLean discusses the connection between fishing pressure and extinction risk for large predatory fish such as tunas and sharks. He’s joined by Maria José Juan Jordá, a postdoc at the Spanish Institute for Oceanography, to learn what a new continuous Red List Index using the past 70 years of fisheries data can tell us about the effectiveness and limits of fishing regulations. Finally, in a sponsored segment from the Science/AAAS Custom Publishing Office, Sean Sanders, director and senior editor for custom publishing, interviews Joseph Hyser, assistant professor in the Department of Molecular Virology and Microbiology at Baylor College of Medicine about his use of wide-field fluorescence live cell microscopy to track intercellular calcium waves created following rotavirus infection.

On this week’s show: How urban spaces can help conserve species, and testing a gene therapy strategy for epilepsy in mice First up on the podcast, we explore urban ecology’s roots in Berlin. Contributing Correspondent Gabriel Popkin joins host Sarah Crespi to discuss turning wastelands and decommissioned airports into forests and grasslands inside the confines of a city. Next, we hear about a gene therapy strategy for epilepsy. Yichen Qiu, a recently graduated Ph.D. student and researcher at University College London, talks about introducing a small set of genes into neurons in mice. These genes detect hyperactivity in the brain and respond by quieting the cell, ultimately suppressing seizures. This week’s episode was produced with help from Podigy.

On this week’s show: Cheaper launches could make solar power satellites a reality, machine learning helps chemists make small organic molecules, and a book on the extinction of foods First up on the podcast, space-based solar power gets closer to launch. Staff Writer Daniel Clery talks with host Sarah Crespi about how reusable rockets bring the possibility of giant solar array satellites that beam down gigawatts of uninterrupted power from space. After that, we hear about small organic molecule synthesis. Making large organic molecules such as proteins and DNA can be a cinch for chemists, but making new smaller organic molecules is tough—partially because optimized general reaction conditions are hard to come by. Nicholas Angello, a graduate research assistant and Department of Defense National Defense Science and Engineering Graduate fellow in the Burke group at the University of Illinois, Urbana-Champaign, talks about an approach that uses robots and machine learning to better optimize these reaction conditions. Also in the episode: the last in our series of books on food and agriculture. This month, host Angela Saini talks with author Dan Saladino about his book Eating to Extinction: The World’s Rarest Foods and Why We Need to Save Them.
