  • A fungus-driven robot, counting snow crabs, and a book on climate capitalism
    First up this week on the podcast, the latest conservation news with Staff Writer Erik Stokstad. Stokstad and host Sarah Crespi talk about the fate of snow crabs in the Bering Sea, how much we have been overestimating fishing stocks worldwide, and invasive snakes in Guam that bite off more than they can chew.   Next, a fungus takes the wheel. Anand Mishra, a research associate in the department of mechanical and aerospace engineering at Cornell University, discusses a method of integrating electronics with fungal cells in a biohybrid robot. By using the hardy cells from a mushroom instead of the delicate cells of an animal, Mishra and colleagues hope to durably introduce the sensing and signaling capacity of these living organisms into robots.   Finally, the fourth installment of our six-part series on books that look to an optimistic future. This month, host Angela Saini talks with science writer Akshat Rathi about how capitalism might just save us from climate change and his book Climate Capitalism: Winning the Race to Zero Emissions and Solving the Crisis of Our Age.   This week’s episode was produced with help from Podigy.   About the Science Podcast   Authors: Sarah Crespi; Erik Stokstad; Angela Saini   Episode page: https://www.science.org/doi/10.1126/science.zt21ifv Learn more about your ad choices.

  • Saving wildlife with AI, and randomized trials go remote
    First up this week on the show, uncounted kilometers of fences are strung across the globe. Researchers know they interfere with wildlife migrations and sometimes make finding food and safety difficult for animals. But they don’t know where all these fences are. Freelancer science journalist Christine Peterson joins host Sarah Crespi to discuss how artificial intelligence and aerial photos could help create fence inventories and eventually reopen spaces for native species.   Next, Azizi Seixas, interim chair of the University of Miami Miller School of Medicine’s department of informatics and health data science and a professor in the department of psychiatry and behavioral sciences, discusses his review on decentralized randomized trials. Randomized, controlled trials based in a research center or centers have long been the gold standard for determining the effectiveness of a medical intervention. This week on the podcast, Seixas argues that distributed research designs with home-based measurements and reporting have the potential to speed up research, allow greater participation, and make the results of studies more equitable.   This week’s episode was produced with help from Podigy.   About the Science Podcast   Authors: Sarah Crespi, Christine Peterson   About the Science Podcast: https://www.science.org/content/page/about-science-podcast Learn more about your ad choices.

  • The humidity vs. heat debate, and studying the lifetime impacts of famine
    Researchers debate if humidity makes heat more deadly, and finding excess diabetes cases in Ukrainian people that were born right after the 1930s famine First up this week, which is worse: the heat or the humidity? Staff writer Meredith Wadman joins host Sarah Crespi to talk about conflicting reports on the risk of increased mortality when humidity compounds heat, and how to resolve the debate in the field.     Next, LH Lumey, a professor of epidemiology at the Columbia University Medical Center, discusses what the catastrophe of a famine can teach us about the importance of maternal and fetal health for the long term. His work focuses on records of a 1930s Ukrainian famine painstakingly reconstructed by Ukrainian demographers after being obscured by the former Soviet Union. The famine records combined with newer data show that babies gestated during famine are more likely to acquire type 2 diabetes later in life.    This week’s episode was produced with help from Podigy.   About the Science Podcast   Authors: Sarah Crespi, Meredith Wadman    Episode page: https://www.science.org/doi/10.1126/science.z6yms94   About the Science Podcast: https://www.science.org/content/page/about-science-podcast Learn more about your ad choices.

  • Iron-toothed dragons, and improving electron microscopy
    First up this week, we hear about caves on the Moon, a shake-up at Pompeii, and the iron-lined teeth of the Komodo dragon. Reporter Phie Jacobs joins host Sarah Crespi to discuss these news stories and more from our daily newsletter, ScienceAdviser.   Next on the show, electron microscopes allow us to view a world inaccessible to light—at incredible resolution and tiny scales. But bombarding samples with a beam of electrons has downsides. The high-energy electrons used for visualizing minute structures can cause damage to certain materials. Jonathan Peters, a research fellow in the School of Physics at Trinity College Dublin, joins the podcast to talk about a new approach that protects samples while keeping resolution sharp.    This week’s episode was produced with help from Podigy.   About the Science Podcast   Authors: Sarah Crespi, Phie Jacobs,   Episode page: https://www.science.org/doi/10.1126/science.zeecyfw Learn more about your ad choices.

  • New treatments for deadly snake bites, and a fusion company that wants to get in the medical isotopes game
    First up this week, Staff Writer Adrian Cho talks with host Sarah Crespi about a fusion company that isn’t aiming for net energy. Instead, it’s looking to sell off the high-energy neutrons from its fusion reactors for different purposes, such as imaging machine parts and generating medical isotopes. In the long run, the company hopes to use money from these neutron-based enterprises for bigger, more energetic reactors that may someday make fusion energy. Next, we hear from Tian Du, a Ph.D. candidate in the Dr John and Anne Chong Lab for Functional Genomics at the University of Sydney. She talks about finding antivenom treatments by screening all the genes in the human genome. Her Science Translational Medicine paper focuses on a strong candidate for treating spitting cobra bites, but the technique may prove useful for many other venomous animal bites and stings, from jellyfish to spiders.
