  • 1155 - Leaf-based computer chips, and evidence that two early human ancestors coexisted

    First up this week, making electronics greener with leaves. Host Sarah Crespi talks with Newsletter Editor Christie Wilcox about using the cellulose skeletons of leaves to create robust, biodegradable backings for computer chips. This sustainable approach can be used for printing circuits and making organic light-emitting diodes and if widely adopted, could massively reduce the carbon footprint of electronics.  Next on the show, Kevin Hatala, a biology professor at Chatham University, joins producer Meagan Cantwell to discuss fossil footprints unearthed in the Turkana Basin of Kenya. A 13-step long track with three perpendicular footprints likely show two different species of early humans, Homo erectus and Paranthropus boisei, walked on the same shorelines.

  • 1154 - Testing whales’ hearing, and mapping clusters of extreme longevity

    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.   This week’s episode was produced with help from Podigy.   About the Science Podcast   Authors: Sarah Crespi; Ignacio Amigo; Kevin McLean Learn more about your ad choices.

  • 1153 - Resurrecting a ‘flipping ship,’ and solving the ‘bone paradox’ in ancient remains

    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?   This week’s episode was produced with help from Podigy.   About the Science Podcast   Authors: Sarah Crespi; Sean Cummings Learn more about your ad choices.

  • 1152 - Watching continents slowly break apart, and turbo charging robotic sniffers

    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.

  • 1151 - The challenges of studying misinformation, and what Wikipedia can tell us about human curiosity

    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.
