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?

Maurice Pitesky, associate professor, UC Davis School of Veterinary Medicine and University of California Agriculture and Natural Resources Cooperative Extension specialist

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.

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.

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 Department of Food Science and Technology

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.

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.

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

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.”

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.
