The podcast discusses the aftermath of the Tonga volcanic eruption, including severed seafloor cables and challenges in modeling energy flow in the electrical grid. It also explores the detection and study of underwater volcanic eruptions, the damage to seafloor cables in Tonga, and the potential for predicting volcanic eruptions. Additionally, it highlights the international collaboration in studying ocean currents and the challenges of connecting renewable energy to the US grid, including permission issues and grid overload.

Laird Kramer, professor of physics at FIU, discusses improving calculus instruction and reducing calculus trauma. Science staffers share their own calculus struggles. Emily Mayhew, professor at Michigan State University, talks about teaching AI to predict smells based on chemical structure.

Lakshmi Pradeep Chitta, research group leader at the Max Planck Institute for Solar System Research, discusses the origin of solar wind and its relation to tiny jets in coronal holes. The podcast also includes stories on cyberattacks affecting telescopes, a water crisis in Uruguay, and a book on how institutions decide gender.

Online News Editor Mike Price joins host Sarah Crespi to discuss what killed off North America's megafauna, including dire wolves and saber-toothed cats, and how ancient wildfires may have played a role. Then, doctoral researcher Olena Shcherbakova explores how language complexity changes under different social and linguistic environments.

First up on this week’s show, we hear about the skewed perception of our own hands, extremely weird giant viruses, champion regenerating flatworms, and more from Newsletter Editor Christie Wilcox. Christie also chats with host Sarah Crespi about her work on a daily newsletter and what it takes to do it 5 days a week. Read more newsletters and sign up for your daily dose of Science and science. Next on the show, AAAS Intern Andrew Saintsing learns about why trees are repulsive—to one another. Michael Kalyuzhny, a postdoctoral fellow in the department of integrative biology at the University of Texas at Austin, discusses his Science paper on why trees of the same species avoid living close together in diverse habitats such as rainforests.   This week’s episode was produced with help from Podigy.   About the Science Podcast   Authors: Sarah Crespi, Andrew Saintsing, Christie Wilcox   Episode page: https://www.science.org/doi/10.1126/science.adk2064 Learn more about your ad choices.

Bringing together ancient DNA from a burial site and a giant database of consumer ancestry DNA helps fill gaps in African American ancestry, and a reckoning for Philadelphia’s Mütter Museum   First up on this week’s show, ancient DNA researchers and ancestry giant 23andMe joined forces to uncover present day ties to a cemetery at the Catoctin Furnace ironworks in Maryland, where enslaved people were buried. Contributing producers and hosts of the Dope Labs podcast Titi Shodiya and Zakiya Whatley spoke with authors Éadaoin Harney and David Reich about the historical significance of this work and how it may help some African American communities recover parts of their lost genealogy. Our News team also covered the paper here.   Next we have a conversation with Staff Writer Rodrigo Pérez Ortega about Philadelphia’s famously creepy Mütter Museum. He talks to producer Kevin McLean about his recent story on the ethics of showcasing the various medical curiosities that the museum is known for.   This week’s episode was produced with help from Podigy.   About the Science Podcast   Authors: Sarah Crespi, Kevin McLean, Titi Shodiya, Zakiya Whatley, Rodrigo Pérez Ortega   Episode page: https://www.science.org/doi/10.1126/science.adk1038  Learn more about your ad choices.

On this week’s show: evaluating scientific collaborations between independent scholars and industry, farming in ancient Europe, and a book from our series on sex, gender, and science.   First up on this week’s show, a look behind the scenes at a collaboration between a social media company and 17 academics. Host Sarah Crespi speaks with Michael Wagner, a professor at the University of Wisconsin-Madison’s School of Journalism and Mass Communication who acted as an impartial observer for Meta’s U.S. 2020 election project. Wagner wrote a commentary piece about what worked and what didn’t in this massive project, which will spawn more than 15 papers, three of them out this week in Science.   Then, producer Meagan Cantwell speaks with Silvia Valenzuela Lamas about her talk about how sociopolitical changes shaped livestock in ancient Europe. Her talk was part of a session on migrations and exchanges in ancient civilizations from this year’s AAAS Annual Meeting.   Also this week, the latest in our book series on sex, gender, and science. Host Angela Saini talks with author Amanda Lock Swarr about her book: Envisioning African Intersex: Challenging Colonial and Racist Legacies in South African Medicine.   This week’s episode was produced with help from Podigy.   About the Science Podcast Learn more about your ad choices.

A massive effort by African volunteers is ensuring artificial intelligence understands their native languages, and measuring 40,000 skeletons Our AI summer continues with a look at how to get artificial intelligence to understand and translate the thousands of languages that don’t have large online sources of text and audio. Freelance journalist Sandeep Ravindran joins host Sarah Crespi to discuss Masakhane, a volunteer-based project dedicated to spurring growth in machine learning of African languages. See the whole special issue on AI here.   Also this week on the show, Eucharist Kun, a Ph.D. student at the University of Texas at Austin, and colleagues used machine learning to take skeletal measurements from x-rays stored in the UK Biobank. Kun discusses links from these body proportions to genes, evolution, and disease.   Finally, in a sponsored segment from the Science Custom Publishing Office, Erika Berg, director and senior editor of custom publishing, interviews Aysha Akhtar, co-founder and CEO of the Center for Contemporary Sciences, about how the Food and Drug Administration Modernization Act 2.0 along with advances in technology are clearing the way for alternatives to animal testing in the development of new drugs. This segment is sponsored by Michelson Philanthropies.   This week’s episode was produced with help from Podigy.   About the Science Podcast   Authors: Sarah Crespi; Sandeep Ravindran   Episode page: https://www.science.org/doi/10.1126/science.adj7646 Learn more about your ad choices.

Science’s NextGen voices share their thoughts on artificial intelligence, how to avoid creating sociopathic robots, and a visit to a historic observatory as researchers pack their bags   As part of a Science special issue on finding a place for artificial intelligence (AI) in science and society, Producer Kevin McLean shares voices from the next generation of researchers. We hear from students about how they think human scientists will still need to work alongside AI in the future.   Continuing the AI theme, we learn about instilling empathy to get better decisions from AI. Researcher Leonardo Christov-Moore, a neuroscientist at the Institute for Advanced Consciousness Studies, discusses his Science Robotics piece on the importance of feelings for future iterations of AI with host Sarah Crespi.    Finally, the status of the Arecibo Observatory. Sarah talks with Contributing Correspondent Claudia López Lloreda in Puerto Rico about scientists wrapping up their work at the facility, and the uncertain future of both their work prospects and the site itself.   This week’s episode was produced with help from Podigy.   About the Science Podcast   Authors: Sarah Crespi; Kevin McLean; Claudio Lopez Lloreda   Episode page: https://www.science.org/doi/10.1126/science.adj7011 Learn more about your ad choices.

Worldwide survey kills the myth of “Man the Hunter,” and tightly constraining the electric dipole moment of the electron   First up this week on the show, freelance science writer Bridget Alex joins host Sarah Crespi to discuss busting the long-standing myth that in our deep past, virtually all hunters were men and women tended to be gatherers. It turns out women hunt in the vast majority of foraging societies, upending old stereotypes.   After that, we learn about a hunt for zero. Tanya Roussy, a recent Ph.D. graduate in quantum physics from the University of Colorado, Boulder, discusses her work trying to constrain the electric dipole moment of the electron. She also talks about why the dipole moment being zero could be just as interesting as not zero to people studying the big mysteries of the universe—such as why matter and antimatter didn’t wipe each other out at the beginning of the universe.
