How Antarctica got its ice sheets, and what happens when geopolitical relationships turn chilly in the Arctic

Owl wars and the immune system’s memory

First up on the podcast, Contributing Correspondent Warren Cornwall goes on an owl hunt in the woods of Northern California. After surviving logging and habitat destruction in the 1990s, the endangered Northern spotted owl has put conservationists in a bind: In order to protect the spotted owl, the only solution may be shooting barred owls [https://www.science.org/doi/10.1126/science.zjuik7j]. Next on the show, looking back at the first 10 years of the journal Science Immunology [https://www.science.org/doi/10.1126/sciimmunol.aej2527]. Editor Seth Thomas Scanlon explores how the field has changed since the inception of the journal and talks about a special series of reviews on immune memory.

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 [https://www.science.org/doi/10.1126/science.zbi5fkr] of this region so important to the study of climate change. Next on the show, producer Meagan Cantwell talks with Thomas Gernon [https://www.southampton.ac.uk/people/5x7llb/professor-thomas-gernon], a geologist at the University of Southampton, about how ice sheets formed in Antarctica [https://www.science.org/doi/10.1126/science.adz6758] during a time when the temperatures were relatively warm.

An electronic nose that detects spoiled chicken, and wolves make a spectacular comeback in Europe

First up on the podcast, wrangling wolves in Europe [https://www.science.org/doi/10.1126/science.zk8ch0m]. After near extermination in much of the continent, wolf numbers have surged up to about 20,000 individuals. Contributing Correspondent Gretchen Vogel joins podcast host Sarah Crespi to discuss the conflicts that have risen as the wolf population grows. Next on the show, Ph.D. student Carla Bassil talks about designing an e-nose that can hone in on important food smells [https://www.science.org/doi/10.1126/sciadv.aec7965] such as chicken that has gone bad or the presence of allergens including peanuts. Finally, in a sponsored segment from the Science/AAAS Custom Publishing Office, Erika Berg, director and senior editor of custom publishing, interviews professors Eimear Kenny [https://profiles.icahn.mssm.edu/eimear-kenny] and Alex Charney [https://profiles.icahn.mssm.edu/alexander-w-charney] about how genomic medicine, artificial intelligence, and large-scale sequencing are transforming the future of patient care.

How childhood environments shape the brain, and how susceptible is the Atlantic Ocean’s current to climate change?

First up on the podcast, producer Kevin McLean talks with Staff Writer Paul Voosen about the latest on the Atlantic Meridional Overturning Circulation, or AMOC. Researchers have long been concerned that global warming could cause a collapse in the AMOC, which would trigger dramatic cooling in Northern Europe. But recent data and models suggest the AMOC may be more resilient than previously thought [https://www.science.org/doi/10.1126/science.zouk18z]. Next on the show, Scott Marek [https://www.mir.wustl.edu/employees/scott-marek/], assistant professor in the Mallinckrodt Institute of Radiology at Washington University School of Medicine, talks with host Sarah Crespi about brainwide association studies (BWAS) for childhood brain development. BWAS measure structure and function across many brains and look for correlations between these measures and behavior, disease, and environment. In this work, Marek and colleagues focus on how socioeconomic factors—captured by zip code—are strongly correlated with certain brain differences in more than 4000 children ages 9.5 to 11. The work also suggests lack of sleep and excess screen time could mediate the influence of socioeconomic conditions [https://www.science.org/doi/10.1126/science.aee6213] on differences in brain structure and function.
