When two major wildfires burned through the Sierra Nevada in 2020 and 2021, they took thousands of giant sequoia trees with them. Without prescribed burns, thousands more would have died, according to a new study from the University of California, Davis. 

A summer beach day in Oregon often involves a cool, gray blanket of fog that not only shapes the experience of beachgoers, but also the coastal and inland environment. 

Now, commercially available surfing webcams are helping scientists measure Oregon’s coastal fog, according to a study from the University of California, Davis, in collaboration with the USDA Forest Service.

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.

Scientists are detecting nanoplastics nearly everywhere, from Antarctica to the human brain, but lack established methods for understanding how they affect human health. University of California, Davis, researchers have received a nearly $4 million grant from the National Institute of Environmental Health Sciences to develop the world’s first standardized method for measuring and describing the neurotoxicity of airborne nanoplastics.

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.

Staring into the depths of Lake Tahoe, you might think the view goes on forever. But researchers at the UC Davis Tahoe Environmental Research Center have been tracking precisely how far a person can see through the famed lake’s waters for nearly 60 years and sharing the results in the annual Lake Tahoe Clarity Report. 

The UC Davis College of Agricultural and Environmental Sciences, or CA&ES, is celebrating two outstanding graduate students recognized for their research, leadership and service in advancing regenerative agriculture, wildlife ecology and conservation and environmental sustainability.
