First up on the podcast, Senior International Correspondent Richard Stone joins host Sarah Crespi to discuss how climate is pushing the disease-carrying tick Hyalomma marginatum out of its comfort zone. Stone reports from Kosovo, where the tick has long been endemic, on how surveillance can uncover hidden circulation—and help countries prepare before human cases appear.

Next on the show, researchers have long known ambient temperatures cause some species of amphibians to reverse sex. In the case of the agile frog (Rana dalmatina), genetically female frogs take on male characteristics at elevated temperatures—including the ability to sire offspring. Veronika Bókony, an evolutionary ecologist at the Center for Agricultural Science in Hungary, examined what happens to the offspring of sex-reversed agile frogs, which will probably make up more of the species’ population as the planet warms.

First up on the podcast, will it ever make economic sense to produce drugs and biomedical supplies in space? Associate Online News Editor Michael Greshko discusses his story on the researchers attempting to make biomanufacturing in space a reality, with News intern Julia Vaz.

Next on the show, producer Kevin McLean chats with Mads Peter Heide-Jørgensen, a professor in the department of birds and mammals at the Greenland Institute of Natural Resources, about how narwhals have helped collect hard-to-reach oceanographic samples. Data collected by these long-toothed cetaceans revealed far more warm Atlantic water is pressing into the fjords of East Greenland than previously thought.

Finally, the latest in our book series on biographies. This month, books host Angela Saini talks with writer Priyambada Jayakumar about her biography of M. S. Swaminathan.

First up on the podcast, the News team’s Diverse Voices in Science Journalism interns Mona Patterson and Laura Martín Agudelo join host Sarah Crespi to talk over some of their reporting from the summer. They chat about several stories, including why it’s so difficult to track the food-borne illness cyclosporiasis and a new map for a major highway of the human nervous system.

Check out all of Patterson’s and Martín Agudelo’s stories.

Next on the show, Leslie Chan, assistant professor in the Wallace H. Coulter Department of Biomedical Engineering at the Georgia Institute of Technology and the Emory School of Medicine, describes an ingestible metabolic probe for the gut microbiome. Her team tested the pill in mice and showed they could detect an enzyme made by the microbiome that causes toxicity during some chemotherapy treatments. The signal is read from volatiles in the breath, making the test a noninvasive way to check on the activity of gut microbes.

First up on the podcast, ScienceInsider Editor Jocelyn Kaiser joins host Sarah Crespi for the latest science policy news. The two discuss recent grant cancellations by the U.S. National Institutes of Health and the likelihood that the agency will spend its budget by the end of its fiscal year on 30 September.

Next on the show, crew aboard spacecraft that enter deep space are likely to be exposed to a radiation source we don’t often encounter on Earth’s surface: high-speed protons coming from solar storms or cosmic rays. So to protect astronauts, researchers are using plastics to defend against this dangerous form of radiation. Jordan Houri, lead scientist for space exploration at StemRad, talks about testing the protective capabilities of specially designed vests aboard NASA’s Artemis I mission.

First up on the podcast, Deputy News Editor Michael Price discusses the history of the North American bison population, its decline, and resurrection—and links to Indigenous cultures. He’s joined by University of California, Santa Cruz evolutionary molecular biologist Beth Shapiro and Greg Wilson, a wildlife ecologist with Parks Canada. They talk about their Science paper on the genetic diversity of modern bison after near extermination during European colonization. Shapiro and Wilson also explain how these findings can be used to inform conservation efforts.

Next on the show, Jennie Brand-Miller, professor emeritus in the School of Life and Environmental Sciences and Charles Perkins Centre at the University of Sydney, joins host Sarah Crespi to talk about what our ancient ancestors were eating and a big question—was hunting key to evolving big brains? Brand-Miller argues instead that fruit was the key factor in the expansion of hominin brains. She points to the high sugar demands of large brains, about 100 to 120 grams per day, and how this level of sugar intake was likely only achievable by consuming things such as fruit and honey before our ancestors’ mastery of cooking and fire.

First up on the podcast, we catch up with Celina Zhao, a staff reporter for Science’s AI In Science reporting initiative. She talks with host Sarah Crespi about artificial intelligence’s knack for finding legal loopholes and how philosophers are navigating conflicts of interest around advising companies on AI.

Next on the show, it’s hard to figure out how much force a muscle is exerting without sticking invasive probes into the body. Christopher Bird, a Ph.D. candidate in the School of Biomedical Sciences at the University of Queensland, discusses a new way to use ultrawideband radar to measure muscle forces that could prove useful for assistive devices and rehabilitation.

Finally, the third in our limited six-part series on scientific biographies. This month, host Angela Saini talks with zoologist Matthew Cobb about his new book on the life of Francis Crick, Crick: A Mind in Motion.

First up on the podcast, freelance science journalist Brendan Borrell talks about his work reporting on the previously undisclosed death of a 6-year-old girl in a gene-editing clinical trial in China and the reasons her parents came forward.

This story was produced in collaboration with Retraction Watch and supported by the Science Fund for Investigative Reporting.

Next on the show, Producer Meagan Cantwell talks with Evan McKenzie, a researcher at the University of British Columbia, about an insect that evolved to avoid predators by modifying its respiratory system to withstand high pressure at depth.
