Rising infections from a dusty devil, and nailing down when our ancestors became meat eaters
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.

Bats surf storm fronts, and public perception of preprints
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.

On the trail with a truffle-hunting dog, and why we should save elderly plants and animals
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.

Top online stories of the year, and revisiting digging donkeys and baby minds
First up this week, Online News Editor David Grimm shares a sampling of stories that hit big with our audience and staff in this year, from corpse-eating pets to the limits of fanning ourselves.
Next, host Sarah Crespi tackles some unfinished business with Producer Kevin McLean. Three former guests talk about where their research has taken them since their first appearances on the podcast.
Erick Lundgren, a researcher at the Centre for Open Science and Research Synthesis at the University of Alberta, revisits his paper on donkeys that dig wells in deserts. Lundgren first appeared on the podcast in April 2021.
Katie Hampson, a professor of infectious disease ecology at the University of Glasgow, discusses where her Tanzanian rabies research has spread. Hampson first appeared on the podcast in April 2022.
Ashley Thomas, an assistant professor of psychology in the Laboratory for Development Studies at Harvard University, talks about why it’s important to plumb the depths of baby minds and the big questions behind her work on children’s understanding of social relationships. Thomas first appeared on the podcast in January 2022.

Science’s Breakthrough of the Year, and psychedelic drugs, climate, and fusion technology updates
First up this week, Breakthroughs Editor Greg Miller joins producer Meagan Cantwell to discuss Science’s 2024 Breakthrough of the Year. They also discuss some of the other scientific achievements that turned heads this year, from ancient DNA and autoimmune therapy, to precision pesticides, and the discovery of a new organelle.
Next, host Sarah Crespi is joined by news staffers to catch up on threads they’ve been following all year. First a bumpy road for certain medicines. Editor Kelly Servick discusses the regulatory hurdles for psychedelic drugs and immunotherapy treatments for Alzheimer’s disease. Then we hear from Staff Writer Paul Voosen about why scientists think this will be the hottest year on record. Finally, what happened with fusion power this year? Staff Writer Daniel Clery brings updates.
