  • Testing whales’ hearing, and mapping clusters of extreme longevity

    Testing whales’ hearing, and mapping clusters of extreme longevity
    Nov 21 2024
    First up this week, where on Earth do people live the longest? What makes those places or people so special? Genes, diet, life habits? Or could it be bad record keeping and statistical flukes? Freelance science journalist Ignacio Amigo joins host Sarah Crespi to discuss the controversies around so-called blue zones—regions in the world where clusters of people appear to have extreme longevity. Next on the show, producer Kevin Mclean talks with Dorian Houser, director of conservation biology at the National Marine Mammal Foundation. Houser and colleagues temporarily captured juvenile minke whales and tested their hearing. It turns out these baleen whales have more sensitive hearing than predicted from vocalizations and anatomical modeling, which could change our understanding of how they are affected by underwater noise pollution.

  • Resurrecting a ‘flipping ship,’ and solving the ‘bone paradox’ in ancient remains

    Resurrecting a ‘flipping ship,’ and solving the ‘bone paradox’ in ancient remains
    Nov 14 2024
    First up this week, a ship that flips for science. Sean Cummings, a freelance science journalist, joins host Sarah Crespi to talk about the resurrection of the Floating Instrument Platform (R/V FLIP), a research vessel built by the U.S. Navy in the 1960s and retired in 2023. FLIP is famous for turning vertically 90° so the bulk of the long ship is underwater, stabilizing it for data gathering. Additional audio from Scripps Institution of Oceanography. Watch FLIP flipping here. Next on the show, viewing past lives using bones from medieval London cemeteries. Samantha Yaussy, a professor in the Department of Sociology and Anthropology at James Madison University, joins Sarah to talk about a bony paradox. Do lesions or scars on buried bones mean the person was frail and ill when they lived or were they strong and resilient because they survived long enough for disease to damage their bones?

  • Watching continents slowly break apart, and turbo charging robotic sniffers

    Watching continents slowly break apart, and turbo charging robotic sniffers
    Nov 7 2024
    First up this week, Staff Writer Paul Voosen talks with host Sarah Crespi about his travel to meet up with a lead researcher in the field, Folarin Kolawole, and the subtle signs of rifting on the African continent. Next on the show, Nik Dennler, a Ph.D. student in the Biocomputation Group at the University of Hertfordshire and the International Center for Neuromorphic Systems at Western Sydney University, discusses speeding up electronic noses. These fast sniffing devices could one day be mounted on drones to help track down forest fires before they are large enough to spot with a satellite.

  • The challenges of studying misinformation, and what Wikipedia can tell us about human curiosity

    The challenges of studying misinformation, and what Wikipedia can tell us about human curiosity
    Oct 31 2024
    First up this week, Contributing Correspondent Kai Kupferschmidt joins host Sarah Crespi to discuss the difficulties of studying misinformation. Although misinformation seems like it’s everywhere, researchers in the field don’t agree on a common definition or shared strategies for combating it. Next, what can Wikipedia tell us about human curiosity? Dani Bassett, a professor in the department of bioengineering at the University of Pennsylvania, observed three different curiosity styles in people browsing the online encyclopedia—hunter, busybody, and dancer. They explain characteristics of each style and how which approach you use could depend on where you live. This week’s episode was produced with help from Podigy.

  • Paleorobotics, revisiting the landscape of fear, and a book on the future of imagination

    Paleorobotics, revisiting the landscape of fear, and a book on the future of imagination
    Oct 24 2024
    Using robots to study evolution, the last installment of our series of books on a future to look forward to, and did reintroducing wolves really restore an ecosystem? First up this week, a new study of an iconic ecosystem doesn’t support the “landscape of fear” concept. This is the idea that bringing back apex predators has a huge impact on the behavior of their prey, eventually altering the rest of the ecosystem. Host Sarah Crespi talks with Contributing Correspondent Virginia Morell about the findings. Next, using bioinspired robotics to explore deep time. Michael Ishida, a postdoctoral researcher in the Bio-Inspired Robotics Lab at the University of Cambridge, talks about studying key moments in evolutionary history, such as the transition from water to land by creating robotic versions of extinct creatures. Finally in the last in our series of books on an optimistic future, books host Angela Saini talks with Ruha Benjamin, a professor of African American studies at Princeton University and recently named MacArthur Fellow. The two discuss Benjamin’s latest book, Imagination: A Manifesto, which explores the part that imagination plays in creating new and radical futures.

  • How to deal with backsliding democracies, and balancing life as a scientist and athlete

    How to deal with backsliding democracies, and balancing life as a scientist and athlete
    Oct 17 2024
    First up this week, host Sarah Crespi talks to Jon Chu, a presidential young professor in international affairs at the Lee Kuan Yew School of Public Policy at the National University of Singapore, about how people around the world define democracy. Does democracy mean elections, freedom of the press, social mobility, or something else? Chu’s team found there was common ground across six countries. In many places with backsliding democracies, leaders may be tempted to change the definition of democracy to their own ends—this study suggests the people they rule won’t be fooled. Next, when staying at home meant choosing between chemistry and basketball, Lena Svanholm sought an opportunity in the U.S. to pursue both. She joins producer Kevin McLean to discuss her next steps in balancing dual careers in science and professional sports. In a sponsored segment from the Science/AAAS Custom Publishing Office, Erika Berg, director and senior editor of Custom Publishing, interviews Michal Elovitz about gaps in women’s health research. This segment is sponsored by the Icahn School of Medicine at Mount Sinai. This week’s episode was produced with help from Podigy.

  • Graphene’s journey from hype to prime time, and harvesting lithium from briny water

    Graphene’s journey from hype to prime time, and harvesting lithium from briny water
    Oct 10 2024
    First up this week, we celebrate 20 years of graphene—from discovery, to hype, and now reality as it finally finds its place in technology and science. Science journalist Mark Peplow joins host Sarah Crespi to discuss graphene’s bumpy journey. Next, producer Meagan Cantwell talks with Seth Darling, chief science and technology officer for the Advanced Energy Technologies Directorate at Argonne National Laboratory, about two new ways to harvest lithium from water. One approach harnesses sunlight to pull water up through a membrane and collect lithium, whereas the other uses an electrochemical cell to selectively suck lithium up. Finding efficient ways to extract lithium from sources where it’s lower in concentration, such as the ocean, will be crucial as demand increases.

  • Scientific evidence that cats are liquids, and when ants started their fungus farms

    Scientific evidence that cats are liquids, and when ants started their fungus farms
    Oct 3 2024
    First up this week, online editor David Grimm joins host Sarah Crespi to talk about how cats think about their own bodies. Do cats think of themselves as a liquid, as much the internet appears to believe? New experiments suggest they may—but only in one dimension. Next, freelance producer Ariana Remmel is joined by Ted Schultz, a research entomologist at the Smithsonian Institution, to discuss the evolution of ant-fungus farming. It turns out, ants and fungus got together when the earth was going through some really tough times around 66 million years ago. This week’s episode was produced with help from Podigy.
