2025/10/01

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.

Just One Spore

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

Fowl News: Bird Flu Ruffles Feathers at the Fair

2025/08/14

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

2025/04/22

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

EV Woes

Consumers once complained about the short range of electric vehicles, but not so much anymore. Now, finding reliable public charging has become the top concern for EV drivers. Chargers can be broken, slow or just inaccessible for multiple reasons. In this episode of Unfold, we talk to UC Davis researchers studying public charging woes and tag along as they drive all over California to test thousands of chargers.In this episode: Alan Jenn, assistant professor, UC Davis Department of Civil and

The Proliferation of Probiotics

2024/11/19

If you’ve perused grocery store shelves lately, you may have noticed a trend – food and beverages labeled probiotic or prebiotic. It’s even on sodas! Labels claim the products “support gut health” or “help boost your immune system.” But is this proliferation of probiotics and prebiotics just marketing or are these microbes really good for you? In this episode of Unfold, a UC Davis microbiologist separates hype from health.In this episode: Maria Marco, microbiologist and professor in the UC Davis

The Promise of Alternative Proteins

2024/09/09

Some call it fake meat – but the burgers of the future could come from a lab, a fungus, a plant or a hybrid that combines animal meat with alternative proteins. UC Davis researchers are looking at ways to bring these proteins to market on a large scale. Experts say it may be the only sustainable way to meet the world’s demand for meat. In this episode of Unfold, you’ll learn more about alternative proteins and the challenge of getting meat eaters to embrace them. In this episode: David Block,

Little Bird, Big City

2024/08/19

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

That Dam Removal Project

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

2024/04/29

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

Close Encounters of the Whale Kind

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

Hormonal Birth Control – It’s a Guy Thing, Too

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

Hey Siri, Why Do I Speak Differently to You?

2023/09/19

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

The Water We Eat: Tackling the Groundwater Dilemma

2023/04/25

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.

There are two kinds of people in this world: Those who love daylight saving time, and those who don’t. UC Davis Health sleep medicine expert Heinrich Gompf is not a big fan of the clock change — or at least not the way we currently do it in the United States. In this episode of Unfold, he tells us why it’s so darn difficult for our bodies to adjust to the time change (the suprachiasmatic nucleus!) and offers tips to help you prepare and adapt when we do spring forward.

Linking Wartime Trauma to Dementia in Vietnamese...

2022/11/15

Since the fall of Saigon in 1975, more than 1.2 million Southeast Asian refugees have resettled in the U.S. Many of them have experienced significant trauma. Now, many Vietnamese refugees in the U.S. are at ages where they’re beginning to develop dementia. But like other underrepresented groups in the U.S, they also face barriers to seeking treatment for trauma and dementia. In this episode of Unfold, we talk to a UC Davis researcher embarking on the first long-term study examining early life

The Human Machine: Reimagining Prosthetics

2022/11/08

Nearly half of all arm amputees choose not to use their prosthesis, despite improvements in technology. Prosthetics can be too difficult to operate, unintuitive, and don’t allow amputees to sense pressure or temperature. At UC Davis, engineers, neuroscientists and surgeons are collaborating to solve this problem. In this episode of Unfold, we look at how the combination of surgery and machine learning is making life easier for amputees. Jonathon Schofield, assistant professor in the Mechanical and
