Summary

What does it mean that we have so many more seamounts than previously thought, and finding REM sleep in seals First up on the show this week: so many seamounts. Staff News Writer Paul Voosen joins host Sarah Crespi to discuss a study that mapped about 17,000 never-before-seen underwater volcanoes. They talk about how these new submarine landforms will influence conservation efforts and our understanding of ocean circulation. Next up, how do mammals that spend 90% of their time in the water, get any sleep? Jessica Kendall-Bar, the Schmidt AI in Science postdoctoral fellow at the Scripps Institution of Oceanography at the University of California, San Diego, is here to talk about her work exploring the sleep of elephant seals by capturing their brain waves as they dive deep to slumber. Finally, in a sponsored segment from Science/AAAS Custom Publishing Office, Jackie Oberst, assistant editor for the Custom Publishing office, interviews Friedman Brain Institute Director Eric Nestler and Director of Drug Discovery Paul Kenny, two experts on addiction from the Icahn School of Medicine at Mount Sinai. This segment is sponsored by the Icahn School of Medicine at Mount Sinai. This week’s episode was produced with help from Podigy.
