As the climate warms, people are more exposed to heat stress, which depresses their productivity and the global economy. A study from the University of California, Davis, quantifies the cost of heat stress on global labor. 

The study, published today in the journal Nature Climate Change, estimates that each ton of carbon dioxide emitted in 2025 cost $41 in lost productivity. 

The University of California, Davis, has joined the Board on Health and Human Sciences within the Association of Public and Land-Grant Universities, with Associate Dean of Human and Social Sciences Amanda Guyer serving as the university’s representative on the national leadership group.

If you've been reaching for chips, mayonnaise or salad dressing labeled "made with avocado oil," there's a good chance the oil inside isn't pure avocado oil, despite it being the only listed oil ingredient. University of California, Davis, researchers tested processed foods marketed as containing avocado oil. They found 48 of the 54 avocado oil-labeled products were adulterated with cheaper oils. The study was published in Applied Food Research. 

A bag of groceries can feed a family, but it may not always feel like home. New research led by the University of California, Davis, finds that labeling foods that are meaningful to different cultures can help local pantries better serve the communities they support.

The Department of Animal Science is hosting its 33rd Annual Production Sale and showcase later this month to auction off seven horses and two mules bred, birthed and trained by undergraduate interns on the UC Davis campus.

As California lawmakers consider legislation that would require “high sugar” warning labels on restaurant menus, a University of California, Davis, study shows that the labels are effective in dissuading diners from ordering sugary items.

A wind-driven brush fire in Simi Valley could push east sending flames and smoke plumes into parts of Los Angeles, less than 18 months after catastrophic wildfires hit the communities of Altadena and Pacific Palisades. 

The lessons from those twin 2025 fires are still being learned as researchers from University of California, Davis, other institutions in the state and the country are working to understand the effect on air quality, human health and the environment. 

Every dollar spent on forest fuel treatments saves about $3.75 in wildfire damages, according to a new study, led by researchers at the University of California, Davis, of nearly 300 fires in the western United States.

Across an expanse of open grassland in Sacramento County, an eight-foot, stream cut bank holds dozens of mud-domed bird nests, where tiny heads peeked out before a colony of cliff swallows took flight. Cliff swallows are small migratory birds that arrive in the Central Valley each spring to breed, and while they now commonly nest on bridges and freeway overpasses, finding their nests built in a natural setting is a striking and special sight, particularly in California’s Central Valley.

A basic income program in Yolo County — one of the first such programs nationwide — lifted unhoused families above the California poverty line for two years. Families could, for a while, spend less time worrying about money and more time being a family, according to new University of California, Davis, research. 

The program provided a monthly stipend to 76 mostly single-parent families between 2022 and 2024, helping them gain housing, food and general wellbeing for two years.
