Mapping uncharted undersea volcanoes, and elephant seals dive deep to sleep

<p><em>What does it mean that we have so many more seamounts than previously thought, and finding REM sleep in seals</em></p> <p> </p> <p>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. </p> <p> </p> <p>Next up, how do mammals that spend 90% of their time in the water, get any sleep? <a href="https://www.jessiekb.com/">Jessica Kendall-Bar</a>, 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 <a href="https://www.science.org/doi/10.1126/science.adf0566">exploring the sleep of elephant seals</a> by capturing their brain waves as they dive deep to slumber.</p> <p> </p> <p>Finally, in a sponsored segment from <em>Science</em>/AAAS Custom Publishing Office, Jackie Oberst, assistant editor for the Custom Publishing office, interviews Friedman Brain Institute Director <a href="https://labs.neuroscience.mssm.edu/project/nestler-lab/">Eric Nestler </a>and Director of Drug Discovery <a href="https://labs.neuroscience.mssm.edu/project/kenny-lab/">Paul Kenny</a>, two experts on addiction from the Icahn School of Medicine at Mount Sinai.
