First up this week, although long touted as a green fuel, the traditional approach to hydrogen production is not very sustainable. Staff writer Robert F. Service joins producer Meagan Cantwell to discuss how researchers are aiming to improve electrolyzers—devices that split water into hydrogen and oxygen—with more efficient and durable designs.

Next, Robert Rogers, who was a postdoctoral fellow in molecular biology at Massachusetts General Hospital when this work was conducted, talks with host Sarah Crespi about the idea of chronic hypoxia as medicine. Efficacious in mouse disease models, the big question now is whether long-lasting reduced oxygen could help people with certain serious conditions, such as mitochondrial defects or brain inflammation. The pair discuss what we know so far about this potential treatment and the challenges of delivering low levels of oxygen around the clock.

First up this week, growing numbers of Valley fever cases, also known as coccidioidomycosis, has researchers looking into the disease-causing fungus. They’re exploring its links to everything from drought and wildfires to climate change and rodent populations. Staff Writer Meredith Wadman joins host Sarah Crespi to discuss her visit to a Valley fever research site in the desert near Bakersfield, California, where researchers are sampling air and soil for the elusive fungus.

Next up, scientists are trying to pin down when meat eating became a habit for human ancestors. It’s long been hypothesized that eating meat drove big changes in our family tree—such as bigger brains and more upright posture. Tina Lüdecke, a group leader at the Max Planck Institute for Chemistry and honorary research fellow at the Evolutionary Studies Institute at the University of the Witwatersrand, investigated the diet of our ancient hominin relatives Australopithecus. Her team used nitrogen isotope ratios from the tooth enamel in seven Australopithecus individuals in South Africa to determine what predominated in their diets at the time—meat or veg.

First up this week, as preprint publications ramped up during the beginning of the COVID-19 pandemic, so did media attention for these pre–peer-review results. But what do the readers of news reports based on preprints know about them? Associate News Editor Jeff Brainard joins host Sarah Crespi to discuss studies that look at the public perception of preprints in the news and how to inject skepticism into stories about them.

Next, placing tiny tags on bats to follow them across central Europe. Former Science intern Edward Hurme—now a postdoctoral fellow in the Department of Migration at the Max Planck Institute of Animal Behavior—revisits the podcast after 13 years. He discusses the difficulty of tracking bats as they fly long distances at night and what new tagging technology is revealing about their migration patterns.

First up this week, Newsletter Editor Christie Wilcox talks with host Sarah Crespi about truffle hunting for science. Wilcox accompanied Heather Dawson, a Ph.D. student at the University of Oregon, and her sister  Hilary Dawson, a postdoctoral researcher at Australian National University, on a hunt for nonculinary truffles—the kind you don’t eat—with the help of a specially trained dog. These scientists and their dog are digging up many new species of these hard-to-find fungi with the ultimate aim of cataloging and conserving them. 

Next, producer Ariana Remmel talks with R. Keller Kopf, an ecologist and lecturer at Charles Darwin University, about the importance of conserving older plants and animals. For example, as certain fish age they produce many more eggs than younger fish. Or in a forest, older trees may provide different ecosystem services than saplings.

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?
