A team of international researchers led by University of California, Davis, released a mobile tool recently that will help small-scale farmers in Asia and Africa craft the right diet for cattle to increase yield and productivity, helping to reduce methane emissions.

Demand for cattle milk and meat in Africa is growing each year. High costs for feed without adequate nutrients reduces productivity and contributes to emissions of methane, a potent greenhouse gas.

In a cozy college town known for bikes and farmers markets, a group of UC Davis students spent their spring and summer doing work beyond the classroom. They immersed themselves in the stories of people in Davis who often go unheard: farmworkers, immigrants, people facing housing challenges and more. As part of a course on environmental justice, they turned those conversations into recommendations for the city’s long-term planning efforts.

The early days with a baby can be overwhelming. Having someone who understands, especially in your own language, can make all the difference. A recent donation to UC Davis is helping ease financial barriers for bilingual students training to become lactation consultants, so they can bring that care to their communities.

At the end of a grocery run, shoppers in Berkeley are now more likely to face fruits and nuts than candy and soda in the checkout lane. A first-of-its-kind city ordinance that took effect in 2021 requires large grocery stores and other retailers to replace sugary drinks and sweets at checkout with healthier options like water, nuts, seeds and fruit.

Pancreatic cancer is one of the deadliest forms of cancer, killing 87% of patients within five years. Previous studies have shown that obesity can increase pancreatic cancer risk by around 50%. In a new study from the University of California, Davis, researchers showed evidence that switching from a high-fat diet to a low-fat diet slowed pancreatic precancer development in mice, even after weight gain and precancerous changes began. The research was published in the Journal of Nutrition.

Motion-activated field cameras, GPS collars, wolf scat analysis and cattle tail hair samples are helping University of California, Davis, researchers shed new light on how an expanding and protected gray wolf population is affecting cattle operations, leading to millions of dollars in losses.

Home is where the perch is: Two peregrine falcons may be turning the UC Davis water tower into their new nesting spot. Andrew “Andy” Engilis Jr., ornithologist and curator of the UC Davis Museum of Wildlife and Fish Biology, spotted a pair of the birds during the first week of April after hearing a loud, high-pitched “scree, scree” outside his office in the Academic Surge building.

Platforms such as iNaturalist and eBird encourage people to observe and document nature, but how accurate is the ecological data that they collect?

An international team of researchers led by Professor Huaijun Zhou from University of California, Davis, created the first-ever detailed map of how genes are regulated in chickens—a breakthrough that could help scientists breed birds that are more resistant to diseases like avian influenza.

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.
