Number 1: Why tracing cyclosporiasis is so tough, and a digestible probe for the microbiome
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. This week’s episode was produced with help from Podigy.

Number 2: Making drugs in space, the man who fed India, and what narwhals can teach us about changing seas
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.

Number 3: Did meat or fruit give people big brains, and protecting bison diversity using ancient DNA
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.

Number 4: A vest for blocking cosmic rays, and updates on NIH funding
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.

Number 5: How Antarctica got its ice sheets, and what happens when geopolitical relationships turn chilly in the Arctic
First up on the podcast, relationships turn chilly in the polar research haven of Svalbard in Norway. Senior International Correspondent Richard Stone joins host Sarah Crespi to discuss the impacts of geopolitical shifts on the scientific output of this region so important to the study of climate change. Next on the show, producer Meagan Cantwell talks with Thomas Gernon, a geologist at the University of Southampton, about how ice sheets formed in Antarctica during a time when the temperatures were relatively warm.
