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. 

Dean Ashley M. Stokes and Associate Dean Anne Todgham with the College of Agricultural and Environmental Sciences at UC Davis will participate in the first ever Agriculture Day at the California State Fair. 

The July 18 event is sponsored by the California Farm Bureau and the California Foundation for Agriculture in the Classroom. Events will run from 10 a.m to 11 p.m. in the Tractor Supply Company Big Barn.

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.

Two new studies examining gray wolves in California paint a complex picture of life on California’s ranching landscapes: Wolves eat cattle more than anything else, and the presence of the predators causes significant stress among livestock.

California’s San Joaquin Valley produces an enormous share of the nation’s fruits, nuts and vegetables. But it takes an unsustainable amount of groundwater to do it. New state rules aimed at reducing groundwater use are expected to force up to 20 percent of the valley’s irrigated fields out of production – a blow to farmers and communities.

Worker bees are the first line of defense when it comes to removing contamination in honeybee colonies, but a queen has her ways, too.

A honeybee queen facing chronic exposure to pesticides will take up that contamination and pass it along to her eggs, a process researchers call maternal offloading. 

The findings, which document for the first time the extent a queen will go to survive, are published in the journal Current Biology. Research was led by the University of California, Davis.

Ice that doesn’t melt. Technology that restores voices. An AI chatbot that can improve your health. Forecasting tools that can protect neighborhoods, people and ecosystems from extreme weather. 

These are just a handful of research advancements supported by federal funding highlighted by UCDavisDelivers, a yearlong online and social media campaign meant to show the impact of research on everyday lives.

Ordering a hamburger might soon come with more than a calorie count. Food systems account for about one-third of global greenhouse gas emissions, and some foods have larger environmental footprints than others. Some restaurants are beginning to display the environmental impact of food items on their menus. A new study led by researchers at the University of California, Davis, shows that climate labels can nudge people toward more environmentally friendly food choices.

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.
