Science Signaling Podcast
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.

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?

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.

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.

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.

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.
