Salty permafrost’s role in Arctic melting, the promise of continuous protein monitoring, and death in the ancient world
First up on the podcast, Science News Editor Tim Appenzeller joins host Sarah Crespi to discuss why a salty layer of permafrost undergirding Arctic ice is turning frozen landscapes into boggy morasses.
Next on the show, glucose isn’t the only molecule in the body that can be monitored in real time; proteins can be, too. Freelancer producer Zakiya Whatley talks with Jane Donnelly, an MD/Ph.D. candidate at Northwestern University, about what we could learn from the live monitoring of key proteins, from the status of a transplanted organ to the early signs of a flare up in autoimmune disease.
Finally, philologist Robert Garland joins books host Angela Saini to talk about ancient cultures and their death practices in his book What to Expect When You’re Dead: An Ancient Tour of Death and the Afterlife.

Protecting newborns from an invisible killer, the rise of drones for farming, and a Druid mystery
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, 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 discusses what appears to drive drone use in agriculture and how they might make farming more productive and sustainable.
Finally, Science Books Editor Valerie Thompson brings books on the secrets rocks have to tell about humanity and the mystery surrounding a Druid preserved in a bog for thousands of years.

An aggressive cancer’s loophole, and a massive field of hydrogen beneath the ocean floor
First up on the podcast, aggressive tumors have a secret cache of DNA that may help them beat current drug treatments. Freelance journalist Elie Dolgin 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, director of the Center of Deep Sea Research at the Chinese Academy of Sciences, about the discovery of a hydrogen-rich system so large 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.

Finding HIV’s last bastion in the body, and playing the violin like a cricket
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, in which people with HIV donate their bodies for rapid autopsy to help find the last reservoirs of the virus.
Next on the show, Christine Elliott, a doctoral candidate in the department of entomology at Purdue University, talks about the Bug Bowl—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 and learn how music connects people to bugs in ways that posters and public lectures can’t.

A mother lode of Mexican mammoths, how water pollution enters the air, and a book on playing dead
First up on the podcast, Staff Writer Rodrigo Pérez Ortega joins host Sarah Crespi to talk about a megafauna megafind 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.
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 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 about her ook Playing Possum: How Animals Understand Death. Content warning for this segment: The interview contains descriptions of dead baby animals.
