One way to understand climate change is by climbing to extremes. In this episode of Unfold, co-host Kat Kerlin trekked up some of the highest peaks in the Sierra Nevada range with UC Davis forest ecologists with the goal of finding the highest altitude Jeffrey pine trees. Their presence can reveal a lot about our warming planet. We’ll hear about her trip – and how a little bird “gardener” can play a large role in reshaping California’s forests. In this episode: Hugh Safford, UC Davis forest ecologist Sachi Srivastava, UC Davis graduate student Mike Mahoney, UC Davis doctoral student Nick Parker, UC Davis undergraduate Read “An Extreme Tree Hunt in the Sierra Nevada Mountains” to learn more about the research.

Valley fever can infect both humans and dogs. In the second and final installment of our series examining valley fever, you’ll hear the story of Cooper, a boxer mix from California’s Central Valley. He nearly lost his life to the fungal infection. In this episode of Unfold, we’ll talk to UC Davis scientists working across medicine and veterinary care to study valley fever. You’ll hear not only about one dog’s fight for survival but how dogs may hold the key to predicting valley fever’s spread in humans.

A single breath and a single spore. That’s all it takes for the fungal infection called valley fever to take hold. For most people, it’s a blip — a treatable illness. But for some, like Rex Dangerfield and Kyleigh Cooyar, it can cause debilitating symptoms. Climate change is creating ideal conditions for the fungus to spread beyond the West. It’s popping up in places where people have never heard of it. In this Unfold episode, we hear how valley fever altered the lives of Rex and Kyleigh, and we hear from UC Davis Health scientists searching for new ways to understand, treat and one day prevent the infection. In this episode: George ThompsonUC Davis Center for Valley Fever Read an in-depth In Focus story on valley fever in both humans and dogs.

This time of year, you’ll hear any number of oinks, neighs and bleats from livestock on show at county fairs. But in California, cock-a-doodle-doos are missing from that chorus. Bird flu has shut down poultry exhibitions. That’s upended life for 4-H members who normally raise chickens and competitively show them at fairs. In this episode of Unfold, guest host Caroline Champlin with University of California Agriculture and Natural Resources visits the Orange County Fair to see how young 4-H-ers are adapting. And we’ll hear from a UC Davis/UC ANR expert on how the virus is adapting to new hosts, including dairy cattle. Is bird flu here to stay? In this episode: Maurice Pitesky, associate professor, UC Davis School of Veterinary Medicine and University of California Agriculture and Natural Resources Cooperative Extension specialist You can read a full article on how bird flu is upending life for 4-H-er's at UC ANR's Green Blog.

Processed food is everywhere—and chances are, you're eating more of it than you think. In this episode of Unfold, we go beyond the ingredient list to uncover the science and public perceptions of processed and ultra-processed foods. Are these foods addictive by design, unsafe or just misunderstood? With insights from food scientists and cultural experts, we’ll examine how modern food manufacturing may be shaping our health, our public policy and even our understanding of what food is. In this episode: Alyson Mitchell, professor and food chemist, UC Davis Department of Food Science and Technology Charlotte Biltekoff, professor in UC Davis Departments of Food Science and Technology and American Studies Read our In Focus story: “What to Know about Processed and Ultra-Processed Foods.” Learn more about processed foods from nutritionists and food scientists in our “Ask the Experts” article.

A tiny songbird called a black phoebe is trying to adapt to city life – and it’s not an easy job. They didn’t naturally evolve in the city, and they face different threats than they might in their natural habitat. Black phoebes may encounter tougher predators, more chemical pollution and hotter temperatures in the city. In this episode of Unfold, we’ll talk to researchers hoping to find a way for humans and the backyard bird to happily coexist. What they learn could help us understand how to protect other bird species whose habitat is threatened by urban sprawl. In this episode: Sage Madden, UC Davis ecology Ph.D. student Jacob Johnson, UC Davis animal behavior Ph.D. student Ian Haliburton, UC Davis master’s candidate in animal behavior Learn more about Project Phoebe by visiting our webpage, www.ucdavis.edu/unfold.

The world’s largest dam removal project is underway along the 250-mile Klamath River in California and Oregon. By the end of 2024, four of the river’s six dams will be demolished. UC Davis scientists are studying whether it will help salmon populations rebound. The fishes’ ear bones could hold clues to their future. In this episode of Unfold, host Amy Quinton discusses the topic with co-host Kat Kerlin, who has written a multimedia feature story about whether restoring the river to its natural state will also restore decimated salmon populations.

You may not know it, but artificial intelligence may be responsible for the food on your table. AI is transforming nearly every aspect of our food system, from before a seed is planted up to the moment that food is eaten. AI could even help you decide what food you should eat based on your own health profile. In this episode of Unfold, we take you on AI’s journey from seed to plate. Host Amy Quinton and guest co-host Andy Fell examine the ways “Big Data Comes to Dinner.” In this episode: Ilias Tagkopoulos, director of the Artificial Intelligence Institute for Next Generation Food Systems at UC Davis Christine Diepenbrock, assistant professor, UC Davis Department of Plant Sciences Mason Earles, assistant professor, UC Davis Departments of Biological and Agricultural Engineering and Viticulture and Enology Christopher Simmons, professor and chair, UC Davis Department of Food Science and Technology Danielle Lemay, associate adjunct professor, UC Davis Department of Nutrition and USDA-ARS Western Health Nutrition Research Center Dan Vincent, former president and CEO of Pacific Coast Producers

Can communication with a humpback whale teach us how to talk to extraterrestrials? Researchers from UC Davis and the SETI Institute want to find out. In the waters of Southeast Alaska, scientists believe they’ve had what might be the very first human-whale communication. The interaction was designed to eventually help us detect and interpret signals coming from outer space. In this episode of Unfold, you’ll hear about the scientists’ remarkable 20-minute “conversation” with a humpback named Twain and what we can learn by studying nonhuman communication on Earth.

Imagine this: A man rubs a hormonal gel on his shoulders once daily, and after a few months his sperm count is zero, giving him and his partner peace of mind that they won’t conceive. That’s been the reality for one couple taking part in a clinical trial for male hormonal birth control at UC Davis Health – and around the world. In this episode of Unfold, we’ll learn more about how the gel works from the physician running the trial, and we’ll chat with the couple about how using the gel has changed their lives. In this episode: Mitchell Creinin, professor of obstetrics and gynecology and a family planning specialist at UC Davis Health Matthew Treviño and Emily Fletcher, couple taking part in the clinical trial Edward Elizarraras, clinical research coordinator at UC Davis Health

If you’ve ever asked Siri or Alexa something, you may have noticed you speak MORE LOUDLY, slowly or make your words “clear-er.” UC Davis researchers say most of us speak differently when talking to our devices. Voice artificial intelligence may even be changing our social behavior. In this episode of Unfold, we’ll talk to two UC Davis linguists to find out why voice AI is changing the way we operate. In this episode: Georgia Zellou, associate professor, Department of Linguistics, UC Davis Michelle Cohn, postdoctoral researcher, Department of Linguistics, UC Davis

You’ve probably heard of groundwater — the water stored underground in aquifers that is a critical natural resource for the western U.S. Did you know that in California, these aquifers provide nearly 40 percent of the water used by farms and communities? During a drought, that figure is even more — nearly 60 percent. Groundwater is vital for growing crops. But California is using this underground resource faster than it can be replenished. In this episode of Unfold, learn how UC Davis researchers are working to make groundwater more sustainable while also helping California remain the most productive agricultural state in the nation. In this episode: Isaya Kisekka, director of the Agricultural Water Center at UC Davis Thomas Harter, hydrologist and distinguished professor in the UC Davis Department of Land, Air and Water Resources Mallika Nocco, assistant professor of Cooperative Extension in soil-plant-water relations and host of the podcast Water Talk Patrick Brown, distinguished professor in the UC Davis Department of Plant Sciences Matthew Roby, research scientist with the U.S. Department of Agriculture Nick Edsall, orchard manager of Bullseye Farms in Yolo County, CA Kirk Pumphrey, owner of Westwind Farms in Yolo County, CA
