Science Magazine Podcast

First up on the podcast, freelance science journalist Leslie Roberts joins host Sarah Crespi to talk about the long journey to a vaccine for group B streptococcus [https://www.science.org/doi/10.1126/science.zycr82a], a microbe that sickens 400,000 babies a year and kills at least 91,000. Next on the show, there are about 250,000 agricultural drones employed on farms in China. Countries such as South Korea, Turkey, and Thailand are swiftly increasing agricultural drone use, whereas the United States and Russia are proceeding more slowly. Food policy researcher Ben Belton [https://www.ifpri.org/profile/ben-belton/] discusses what appears to drive drone use in agriculture [https://www.science.org/doi/10.1126/science.ady1791] and how they might make farming more productive and sustainable. Finally, Science Books Editor Valerie Thompson brings books on the secrets rocks [https://www.science.org/doi/10.1126/science.aeb4192] have to tell about humanity and the mystery surrounding a Druid preserved in a bog for thousands of years.

First up on the podcast, aggressive tumors have a secret cache of DNA [https://www.science.org/doi/10.1126/science.znlfyxc] that may help them beat current drug treatments. Freelance journalist Elie Dolgin [https://www.eliedolgin.com/] joins host Sarah Crespi to talk about targeting so-called extrachromosomal DNA—little gene-bearing loops of DNA—that help difficult-to-treat cancers break the laws of inheritance.   Next on the show, producer Meagan Cantwell talks with Weidong Sun [http://english.qdio.cas.cn/people2016/faculty_and_staff2016/201907/t20190719_213520.html], director of the Center of Deep Sea Research at the Chinese Academy of Sciences, about the discovery of a hydrogen-rich system so large [https://www.science.org/doi/10.1126/sciadv.adx2600] it makes up at least 5% of current estimates for global hydrogen emissions from abiotic sources. They discuss how hydrogen gas rising from the mantle reacting with oxygen could have triggered an explosion that formed holes hundreds of meters across and dozens of meters deep.  This week’s episode was produced with help from Podigy [https://podigy.co/].

First up on the podcast, despite so many advances in treatment, HIV drugs can suppress the virus but can’t cure the infection. Where does suppressed HIV hide within the body? Staff Writer Jon Cohen joins host Sarah Crespi to talk about the Last Gift Study [https://lastgift.ucsd.edu/], in which people with HIV donate their bodies for rapid autopsy [https://www.science.org/doi/10.1126/science.zh8omyn] to help find the last reservoirs of the virus.   Next on the show, Christine Elliott [https://ag.purdue.edu/directory/ellio139], a doctoral candidate in the department of entomology at Purdue University, talks about the Bug Bowl [https://ag.purdue.edu/springfest/]—an annual public outreach event that highlights all the wonders and benefits of insects. We also get to hear the sounds of violins trying to be crickets [https://www.science.org/doi/10.1126/science.adz9348] and learn how music connects people to bugs in ways that posters and public lectures can’t.   This week’s episode was produced with help from Podigy [https://podigy.co/].

First up on the podcast, Staff Writer Rodrigo Pérez Ortega joins host Sarah Crespi to talk about a megafauna megafind [https://www.science.org/doi/10.1126/science.zoydiav] that rivals the La Brea Tar Pits. In addition to revealing tens of thousands of bones from everything from dire wolves to an ancient human, the site has yielded the first DNA from ammoths that lived in a warm climate [https://www.science.org/doi/10.1126/science.adt9651].    Next on the show, the Tijuana River crosses the U.S.-Mexican border from Tijuana to San Diego—bringing with it sewage, industrial waste, and stinky smells. News Intern Nazeefa Ahmed talks with Kimberly Prather, an atmospheric chemist at the University of California San Diego about detecting both air and water pollution [https://www.science.org/doi/10.1126/science.adv1343] around the river and the steps needed for cleanup.   Finally, the latest in our series of books exploring the science of death. This month, host Angela Saini talks with philosopher Susana Monsó [https://susanamonso.com/] about her ook Playing Possum: How Animals Understand Death [https://bookshop.org/p/books/playing-possum-how-animals-understand-death-susana-monso/21108555?ean=9780691260761].

The pair talk about how investigating the role of the immune system in this disease is leading researchers to new potential diagnostic tools and treatments.   Next on the show, why are there good dengue years and bad dengue years? This week in Science Translational Medicine, Talia Quandelacy and colleagues map the synchrony and spread of this mosquito-borne disease in Latin America. She joins the podcast to talk about how the seasons, rainfall, and even El Niño connect with dengue levels and how this understanding can help with prediction and preparation [https://www.science.org/doi/10.1126/scitranslmed.adq4326].   Quandelacy [https://coloradosph.cuanschutz.edu/resources/directory/directory-profile/Quandelacy-Talia-UCD6003653290] is an assistant professor in the department of epidemiology at the University of Colorado School of Public Health.   This week’s episode was produced with help from Podigy [https://podigy.co/].   About the Science Podcast [https://www.science.org/content/page/about-science-podcast]   Authors: Sarah Crespi; Meredith Wadman Learn more about your ad choices.
