    Cleaning up uranium mining, and how the heart avoids cancer

    First up on the podcast, freelance science and environmental journalist Quentin Septer joins host Sarah Crespi to talk about a controversial uranium mine getting fast-tracked in South Dakota. Septer chatted with locals, scientists, and regulators to learn more about the geology of the region and the promise of cleanup after the miners go home. Next on the show, looking at cells that don’t get cancer. Giulio Ciucci, a postdoctoral researcher at the International Centre for Genetic Engineering and Biotechnology, talks about the infrequency of heart cancer and how the mechanical load that heart cells endure makes them resist turning cancerous.

    The normals | Episode 3

    The final of a three-part limited Science Podcast series that looks at the history of normal human subjects in research In episode two, we heard what happened to the normals program after church volunteers came to the U.S. National Institutes of Health’s Clinical Center—and were surprisingly happy despite going through sometimes-painful procedures. In the decades to follow, the program got bigger as government funding expanded and started to recruit more broadly, stepping away from specific religious groups toward recruiting from colleges, universities, and unions. In this episode, we hear about how normal human subjects experience research today and the ways the normals project influenced oversight and safety for these sometimes vulnerable people. All episodes in this series Appearing in this episode: Laura Stark, history professor at the Center for Medicine, Health, and Society at Vanderbilt University Jill Fisher, professor of social medicine in the Center for Bioethics at the University of North Carolina at Chapel Hill Kaviya Manoharan, lecturer and clinical research program manager in the Centre for Clinical Pharmacology, SRM Medical College Hospital and Research Centre Martin Enserink, deputy news editor at Science Kevin McLean, Science multimedia managing producer Sarah Crespi, Science Podcast senior host and producer Additional resources: BOOKS The Normals: A People’s History of Modern America in Five Human Experiments by Laura Stark Adverse Events: Race, Inequality, and the Testing of New Pharmaceuticals by Jill Fisher NEWS STORIES Global effort aims to protect health and safety of human ‘guinea pigs’ in drug trials by Martin Enserink Key global bioethics guidelines get ‘dramatic’ update by Cathleen O’Grady WEBSITES Volrethics Learn more about your ad choices.

  3. How to keep quantum computers cool, whether prediction markets harm public health, and podcasting on podcasting

    16 ABR

    How to keep quantum computers cool, whether prediction markets harm public health, and podcasting on podcasting

    First up on the podcast, quantum computers require extremely low temperatures—less than 1°C away from absolute zero. But getting down to those temperatures has usually required dilution fridges using the extremely rare and increasingly expensive isotope helium-3. Freelance science journalist Zack Savitsky joins host Sarah Crespi to discuss up-and-coming technologies that can drive down temperatures while staying helium-3–free. Next on the show, Nizan Packin, a professor of law at the Zicklin School of Business at Baruch College, talks about prediction markets as a public health threat. Early on, prediction markets were proposed as a way to make reliable forecasts from crowdsourced wisdom. With the appearance of commercial, for-profit prediction markets linked with cryptocurrency and sports betting, Nizan and colleagues ask what studies should be done to better understand potential harms to the public. Finally, in a Working Life column this week, recent Ph.D. graduate Filippo Dall’Armellina wrote about how his foray into science podcasting helped him regain enjoyment of research. He talks about why having a science-adjacent hobby was life changing. This week’s episode was produced with help from Podigy. About the Science Podcast Learn more about your ad choices.

  4. The Normals | Episode 2

    14 ABR

    The Normals | Episode 2

    Last time on The Normals, we learned that in the 1950s, the National Institutes of Health (NIH) wanted to recruit many healthy volunteers for basic research. Two peace churches, the Mennonites and the Church of the Brethren, had an excess of healthy human volunteers. The “Normals” recruited from these Anabaptist churches were surprisingly happy, even as they went through sometimes painful procedures. In this follow-up episode, we hear about how the sources of normal human subjects changed in the 1960s and why NIH researchers felt they needed to expand their search for normal people. We also learn about the first death in the program and the shifting motives on the parts of the researchers and volunteers. Final episode drops next Tuesday, April 21. All Normals episodes In this episode: Laura Stark, history professor at the Center for Medicine, Health, and Society at Vanderbilt University Ken Naas, former Normal patient Cindy Jansen, former Normal patient Dale Horst, former Normal patient Sarah Crespi, Science Podcast senior host and producer Additional resources: The Normals: A People’s History of Modern America in Five Human Experiments by Laura Stark Learn more about your ad choices.

  5. A chimpanzee ‘civil war,’ and NASA plans for nuclear propulsion

    9 ABR

    A chimpanzee ‘civil war,’ and NASA plans for nuclear propulsion

    First up on the podcast, freelance science journalist Hannah Richter joins host Sarah Crespi to discuss NASA’s plans to send a nuclear-powered spacecraft to Mars in less than 3 years. Having not launched a fission reactor to space in more than 60 years, the organization faces many technical and bureaucratic hurdles to make that deadline. Next on the show, Aaron Sandel, associate professor in the Department of Anthropology at the University of Texas at Austin and co-director of the Ngogo Chimpanzee Project, reports this week in Science on what looks like a chimpanzee civil war. The unprecedented violent split occurred in a large chimp colony that has been tracked by researchers for decades. Now, scientists are asking: What can the lethal division of a chimp community teach us about human conflict? This week’s episode was produced with help from Podigy.

    The Normals | Episode 1

    How do we know what's normal in a person? In the early 1950s, the National Institutes of Health (NIH) set out to do something unprecedented. It wanted to start studying normal humans on a grand scale. It had pretty much everything in place: It had the building, it had recruited all of these amazing researchers—it was the healthy human bodies NIH didn't have. How do we know what’s normal in a person? In the early 1950s, the U.S. National Institutes of Health (NIH) set out to do something unprecedented. It wanted to start to study normal humans on a grand scale. It had pretty much everything in place: It had the building, it had recruited all of these amazing researchers—it was the healthy human bodies NIH didn’t have. When the healthy subjects arrived, experimenters tested LSD, sleep devrivation, rice-only diets, and more risky intervetions on them. Where it found those volunteers and what happened next is the story of The Normals.  Starting on 7 April, the Science Podcast will be releasing a new three-part limited series called The Normals. We'll hear from some of the original “Normals,” follow the program through the decades, and see what's happening with healthy human subject research today.

  7. Resolving the dispute over the speed of the expanding universe, and seeking new drug targets for cognitive dysfunction

    2 ABR

    Resolving the dispute over the speed of the expanding universe, and seeking new drug targets for cognitive dysfunction

    First up on the podcast, a new path to calculating the Hubble constant. This value for the universe’s speed of expansion is typically determined in one of two ways, one favored by cosmologists, the other by astronomers. But the resulting values from these methods are consistently different. Staff Writer Daniel Clery joins host Sarah Crespi to discuss how reappearing bursts from deep space, lensed by gravity, could resolve the dispute over the speed of the expanding universe. Next on the show, freelance producer Elah Feder talks with Mauro Costa-Mattioli, principal investigator at Altos Labs’ Institutes of Science, about tuning the “integrated stress response” (ISR) in mouse brains. The ISR pathway turns off much of protein synthesis in cells as a response to stressors such as viral infections or oxygen deprivation. The ISR is overactive in some models of cognitive dysfunction—suggesting the downregulated protein synthesis may hamper brain functions such as memory formation. In his paper, Costa-Mattioli and colleagues show turning on the ISR pathway causes memory problems in mice and turning off the ISR can restore function in mouse models of Alzheimer’s disease and Down syndrome. Although this research was in mice, it suggests cognitive dysfunction associated with many different disorders may involve the ISR—making it a good therapeutic target.

  8. Resurrection plants, Project Hail Mary, and the trouble with sycophantic AI

    26 MAR

    Resurrection plants, Project Hail Mary, and the trouble with sycophantic AI

    First up on the podcast, Deputy News Editor Martin Enserink talks about so-called resurrection plants. These specialized plants can survive up to 95% water loss, whereas most plants struggle when their water levels dip below 60%. We also hear from Jill Farrant, a professor of molecular and cell biology at the University of Cape Town, about her work dissecting the desiccation survival pathways in resurrection plants and how they might be repurposed to protect crop plants from drought. Next on the show, we’ve all heard of chatbots praising their users for asking the most basic of questions. This bias toward sycophancy extends beyond pleasantries into relationship advice the artificial intelligence (AI) doles out to users. Myra Cheng, a Ph.D. candidate in computer science at Stanford University, joins the show to talk about how this tendency for AIs to be agreeable can lead users to have more confidence in their opinions, to the detriment of their relationships with others. Warning, this last segment contains spoilers for the movie and book Project Hail Mary by Andy Weir. If you’ve seen the movie or don’t mind a bit of extra context, you will hear an analysis of planetary science in the film with astrophysicist and associate curator at the American Museum of Natural History, Jacqueline Faherty.
