Guest host Meagan Cantwell talks to Staff Writer Erik Stokstad about a new weapon against crop-destroying beetles. By making pesticides using RNA, farmers can target pests and their close relatives, leaving other creatures unharmed. 

Next, freelance producer Katherine Irving talks to hydrologist Craig Brinkerhoff about a recent analysis of ephemeral streams—which are only around temporarily—throughout the United States. Despite their fleeting presence, Brinkerhoff and his colleagues found these streams play a major role in keeping rivers flowing and clean. Brinkerhoff is currently a postdoctoral fellow at Yale University, and completed this work as a Ph.D. student at the University of Massachusetts Amherst.  

Finally, the next segment in our books series on a future to look forward to. Books host Angela Saini talks with author Rachel O’Dwyer about her recent book Tokens: The Future of Money in the Age of the Platform. They’ll discuss new and old ideas of currency, and what it means to have our identities tied to our money as we move toward a more cashless society.

On this week’s show: Scientists are expanding the hunt for habitable exoplanets to bigger worlds, and why improvements in air quality have stagnated in Los Angeles, especially during summer, despite cleaner cars and increased regulations

Staff Writer Daniel Clery joins producer Meagan Cantwell to talk through the major contenders for habitable exoplanets—from Earth-like rocky planets to water worlds. Preliminary results from two rocky exoplanets have some researchers concerned about whether they will be able to detect atmospheres around planets orbiting turbulent stars.

Next, producer Ariana Remmel talks with Eva Pfannerstill, an atmospheric chemist at the Jülich Research Center, about how volatile organic compounds, mostly from plants, are causing an increase in air pollution during hot days in Los Angeles.

On this week’s show: Companion animals such as dogs occupy the same environment we do, which can make them good sentinels for human health, and DNA gives clues to ancient Maya rituals and malaria’s global spread

Contributing Correspondent Andrew Curry joins host Sarah Crespi to discuss two very different studies that used DNA to dig into our past. One study reveals details of child sacrifices in an ancient Maya city. The other story is on the surprising historical reach of malaria, from Belgium to the Himalayas to South America.

Next on the show, using our canine companions to track human health. Courtney Sexton, a postdoctoral research fellow in the Department of Population Health Sciences at the Virginia-Maryland College of Veterinary Medicine, talks about what we can learn from these furry friends that tend to be exposed to many of the same things we are such as pesticides and cleaning chemicals.

Finally, in a sponsored segment from the Science/AAAS Custom Publishing Office, Jackie Oberst, associate editor of custom publishing, interviews professors Miriam Merad and Brian Brown about the evolution of immunology in health care. This segment is sponsored by the Icahn School of Medicine at Mount Sinai.

Despite not having a known function, cellular “vaults” are on the verge of being harnessed for all kinds of applications, and looking at the evolution of brown fat into a heat-generating organ

First on this week’s show, Managing News Editor John Travis joins host Sarah Crespi to discuss mysterious cellular complexes called “vaults.” First discovered in the 1980s, scientists have yet to uncover the function of these large, common, hollow structures. But now some researchers are looking to use vaults to deliver cancer drugs and viruses for gene therapy.

Next, what can we learn about the evolution of brown fat from opossums? Unlike white fat, which stores energy in many mammals, brown fat cells use ATP to generate heat, helping babies maintain their body temperature and hibernators kick-start their summers. Susanne Keipert, a researcher in the Department of Molecular Biosciences at Stockholm University’s Wenner-Gren Institute, talks about when in evolutionary history brown fat took on this job of burning energy.

Finally, this week we are launching our music refresh! If you are interested in what happened to our music—where it came from and how it’s different (and the same)—stay tuned for a chat with artist Nguyên Khôi Nguyễn.

Studying color vision in with children who gain sight later in life, joining a cancer trial doesn’t improve survival odds, and the first in our books series this year

First on this week’s show, Staff Writer Jennifer Couzin-Frankel joins host Sarah Crespi to discuss the pros and cons of participating in clinical trials. Her story challenges the common thinking that participating in a trial is beneficial—even in the placebo group—for cancer patients.

Next, Lukas Vogelsang, a postdoctoral fellow in the department of brain and cognitive sciences at the Massachusetts Institute of Technology, talks about research into color vision with “late-sighted” kids. Studying children who were born blind and then later gained vision gave researchers new insights into how vision develops in babies and may even help train computers to see better.

Last up on the show is the first in our series of books podcasts on a future to look forward to. Books host Angela Saini talks with author Claire Horn, a researcher based at Dalhousie University’s Health Justice Institute. They discuss the implications of growing babies from fertilized egg to newborn infant—completely outside the body—and Horn’s book Eve: The Disobedient Future of Birth.

A roundup of online news stories featuring animals, and researchers get crows to “count” to four

This week’s show is all animals all the time. First, Online News Editor Dave Grimm joins host Sarah Crespi to discuss stepping on venomous snakes for science, hunting ice age cave bears, and demolishing lizardlike buildings.

Next, producer Kevin McLean talks with Diana Liao, a postdoctoral researcher at the University of Tübingen, about teaching crows to count out loud. They discuss the complexity of this behavior and how, like the famous band, these counting corvids have all the right vocal skills to do it.

On this week’s show: What happens when the body’s own immune system attacks the brain, and how otters’ use of tools expands their diet

First on the show this week, when rogue antibodies attack the brain, patients can show bizarre symptoms—from extreme thirst, to sleep deprivation, to outright psychosis. Contributing Correspondent Richard Stone joins host Sarah Crespi to discuss the hunt for biomarkers and treatments for this cluster of autoimmune disorders that were once mistaken for schizophrenia or even demonic possession.

Next on this episode, producer Katherine Irving talks with Chris Law, an evolutionary biologist at the University of Washington and the University of Texas at Austin, about how sea otters gain energy benefits (and dental benefits) when they use tools to tackle tougher prey such as snails or large clams.

Jupiter’s moon Io has likely been volcanically active since the start of the Solar System, and a proposal to safeguard healthy human subjects in clinical trials

First on the show this week, a look at proposed protections for healthy human subjects, particularly in phase 1 clinical trials. Deputy News Editor Martin Enserink joins host Sarah Crespi to discuss the risks healthy participants face when involved in early testing of drugs for safety and tolerance. Then, we hear about a project to establish a set of global standards initiated by the Ethics Committee of France’s national biomedical research agency, INSERM.

Next on this episode, a peek at the history of the most volcanically active body in the Solar System, Jupiter’s moon Io. Because the surface of Io is constantly being remodeled by its many volcanoes, it’s difficult to study its past by looking at craters or other landmarks. Katherine de Kleer, assistant professor of planetary science and astronomy at the California Institute of Technology, talks about using isotopic ratios in the moon’s atmosphere to estimate how long it’s been spewing matter into space.

Bringing historical seismic reports and modern seismic risk maps into alignment, and a roundup of stories from our newsletter, ScienceAdviser

First on the show this week, a roundup of stories with our newsletter editor, Christie Wilcox. Wilcox talks with host Sarah Crespi about the oldest ice ever found, how well conservation efforts seem to be working, and repelling mosquitoes with our skin microbes.

Next on this episode, evaluating seismic hazard maps. In a Science Advances paper this week, Leah Salditch, a geoscience peril adviser at risk and reinsurance company Guy Carpenter, compared modern seismic risk map predictions with descriptions of past quakes. The analysis found a mismatch: Reported shaking in the past tended to be stronger than modern models would have predicted. She talks with Crespi about where this bias comes from and how to fix it.
