University of California, Davis agricultural economists explore the reasons for reduced egg supplies and high egg prices in a recent article and assess what producers and consumers can expect now that the pathogen has spread through California dairies. The authors find that California egg production in December 2024 was 30% lower than in January 2022, while national production, which is the source of most of California’s retail supply, had declined by much less.

Maria Marco, microbiologist and professor with the Department of Food Science and Technology, has been elected to the 2025 class of fellows for the American Academy of Microbiology. 

Marco has been with UC Davis faculty since 2008 and teaches two upper division food microbiology courses on campus. She has built an internationally recognized research program on fermented foods, probiotics and how diet affects microbes in the gut. Her research examines the beneficial compounds these microbes produce and their impact on human well-being. 

Researchers tempted grazing cattle with sweet molasses feed to discover whether cows would roam far and wide to graze or stick close to the herd, water supplies and feed stations.

The findings by animal scientists at the University of California, Davis and published in the journal Scientific Reports, offer a low-cost way for ranchers and others to identify the best cows for their landscapes to optimize grazing while meeting the nutritional needs of cattle. 

It’s mid-February and many New Year’s resolutions have already fizzled out, with research suggesting that about 80% don’t last past this point. Debbie Fetter, associate professor of teaching with the UC Davis Department of Nutrition, shares some practical tips to help make healthy habits last all year long. Fetter, who teaches the NUT 10 course, earned her Ph.D. in nutritional biology from UC Davis and provides strategies to help make healthy eating and exercise fun and sustainable.

As their traditional dining options dwindle and natural areas give way to restaurants, homes and sidewalks, the coyotes of San Francisco are shifting what they eat.

Scientists from the University of California, Davis, wanted to understand what San Francisco’s coyotes are eating, and how their diet is changed and shaped by the city’s landscape, which can vary from block to block.

It doesn’t require a degree in ornithology, a lab test or even an app for most growers to determine whether bird poop near their crops presents a food safety risk. They just need to ask themselves a simple question: How big is it?

A ground squirrel with cheeks stuffed with nuts, seeds or grains, is a common sight. But a new study provides the first evidence that California ground squirrels also hunt, kill and eat voles. The study, led by the University of Wisconsin-Eau Claire and the University of California, Davis, is the first to chronicle widespread carnivorous behavior among squirrels.

All students, including those from ethnoracially diverse and from white backgrounds, benefit from supportive learning environments that accommodate adolescents’ multiple cultural and ethnic backgrounds, according to new University of California, Davis, research. These benefits span the academic, social and emotional realms.

Outdoor air pollution from power plants, fires and cars continues to degrade human, animal and environmental health around the globe. New research shows that even pollution levels that are below government air-quality standards are associated with differences in children’s brains.

Childhood malnutrition is one of the world's most pressing health challenges, and Kathryn Dewey, distinguished professor emerita in the UC Davis Department of Nutrition, has been at the forefront of efforts to address it. Her pioneering research led to an innovative supplement to combat nutritional deficiencies and has informed and improved global health policies.
