    Extreme ocean currents from a volcano, and why it’s taking so long to wire green energy into the U.S. grid
    How the Tonga eruption caused some of the fastest underwater flows in history, and why many U.S. renewable energy projects are on hold     First up on this week’s show, we hear about extremely fast underwater currents after a volcanic eruption. Producer Meagan Cantwell talks with sedimentary geologist Michael Clare and submarine volcanologist Isobel Yeo, both at the U.K. National Oceanography Centre. They discuss the complex aftermath of the Hunga Tonga-Hunga Ha’apai eruption, including fast and powerful ocean currents that severed seafloor cables.     Watch a related video on last year’s eruption by Meagan: How the Tonga volcanic eruption rippled through the earth, ocean and atmosphere.   Next on the show, an unexpected slowdown in connecting renewable power to the electrical grid. Freelance journalist Dan Charles joins host Sarah Crespi to discuss how problems with modeling energy flow in the electrical grid are holding up wind and solar power projects across the country.   This week’s episode was produced with help from Podigy.   About the Science Podcast   Authors: Sarah Crespi, Meagan Cantwell; Dan Charles   Episode page: https://www.science.org/doi/10.1126/science.adk7170  Learn more about your ad choices.

    Reducing calculus trauma, and teaching AI to smell
    How active learning improves calculus teaching, and using machine learning to map odors in the smell space   First up on this week’s show, Laird Kramer, a professor of physics and faculty in the STEM Transformation Institute at Florida International University (FIU), talks with host Sarah Crespi about students leaving STEM fields because of calculus and his research into improving instruction.   We also hear from some Science staffers about their own calculus trauma, from fear of spinning shapes to thinking twice about majoring in physics (featuring Kevin McLean, Paul Voosen, Lizzie Wade, Meagan Cantwell, and FIU student and learning assistant Carolyn Marquez).   Next on the show, can a computer predict what something will smell like to a person by looking at its chemical structure? Emily Mayhew, a professor in the department of food science and human nutrition at Michigan State University, talks about how this was accomplished using a panel of trained smellers, and what the next steps are for digitizing the sense of smell.    This week’s episode was produced with help from Podigy.   About the Science Podcast   Authors: Sarah Crespi, Kevin McLean; Meagan Cantwell; Paul Voosen; Lizzie Wade     Episode page: https://www.science.org/doi/10.1126/science.adk6142 Learn more about your ad choices.

    The source of solar wind, hackers and salt halt research, and a book on how institutions decide gender
    A close look at a coronal hole, how salt and hackers can affect science, and the latest book in our series on science, sex, and gender First up on this week’s show, determining the origin of solar wind—the streams of plasma that emerge from the Sun and envelope the Solar System. Host Sarah Crespi talks with Lakshmi Pradeep Chitta, a research group leader at the Max Planck Institute for Solar System Research, about how tiny jets in so-called coronal holes seem to be responsible. Sarah also talks with Science Editor Keith Smith about the source of the data, the Solar Orbiter mission. Read a related Perspective.   Next, two stories on unlikely reasons for slowing science. First, cyberattacks on telescopes scramble ground-based astronomy in Hawaii and Chile, with Diverse Voices Interns Tanvi Dutta Gupta and Celina Zhao. Also, we hear about an unparalleled water crisis in Uruguay that has left scientists high and dry, with science journalist María de los Ángeles Orfila.   Finally, in this month’s books segment in our series on science, sex, and gender, host Angela Saini talks with author and political scientist Paisley Currah about his book, Sex Is as Sex Does: Governing Transgender Identity, on why and how government institutions categorize people by sex and gender.   This week’s episode was produced with help from Podigy.   About the Science Podcast   Authors: Sarah Crespi, Angela Saini; María de los Ángeles Orfila; Celina Zhao; Tanvi Dutta Gupta   Episode page: https://www.science.org/doi/10.1126/science.adk4714 Learn more about your ad choices.

    What killed off North American megafauna, and making languages less complicated
    Ancient wildfires may have doomed Southern California’s big mammals, and do insular societies have more complex languages?   First up on this week’s show, what killed off North America’s megafauna, such as dire wolves and saber-toothed cats? Online News Editor Mike Price joins host Sarah Crespi to talk about the likely culprits: climate or humans, or one that combines both—fire. They discuss how the La Brea Tar Pits are helping researchers figure this out. Read the related Science paper.   Next up, do languages get less complex when spoken in multilingual societies? Olena Shcherbakova, a doctoral researcher at the Max Planck Institute for Evolutionary Anthropology, joins Sarah with a broad look at how the complexity of languages changes under different social and linguistic environments.   In a sponsored segment from the Science/AAAS Custom Publishing Office, Jackie Oberst, associate editor for custom publishing, discusses with Trine Bartholdy, chief innovation officer at the BioInnovation Institute, an international life science incubator in Copenhagen, Denmark, about the continued disparity in women’s health research and funding and ways in which these challenges are being overcome. This segment is sponsored by the BioInnovation Institute.   This week’s episode was produced with help from Podigy.   Authors: Sarah Crespi, Mike Price   Episode page: https://www.science.org/doi/10.1126/science.adk3475    About the Science Podcast: https://www.science.org/content/page/about-science-podcast Learn more about your ad choices.
