Canada’s crude oil releases higher emissions than U.S. sources

Gasoline and diesel fuel extracted and refined from Canadian oil sands will release about 20 percent more carbon into the atmosphere over its lifetime than fuel from conventional domestic crude sources, according to a study by the U.S. Department of Energy’s Argonne National Laboratory, UC Davis and Stanford University. The researchers used a life-cycle, or […]

California’s wildflowers losing diversity in warmer, drier winters

Native wildflowers in California are losing species diversity after multiple years of drier winters, according to a study from UC Davis, which provides the first direct evidence of climate change impacts in the state’s grassland communities. The study, published Monday in the journal Proceedings of the National Academy of Sciences, is based on 15 years […]

Sea stars, urchins foretell long-term marine changes

In August 2011, scientists at the UC Davis Bodega Marine Laboratory walked into their labs to a strange, disturbing sight: Thousands of purple sea urchins and other marine invertebrates were dead in their tanks, which are fed directly by seawater. Outside, the tea-colored ocean washed up carcasses of red abalone, large sea stars and football-sized, […]

UCD team helping care for oiled wildlife in Santa Barbara

Team members from the Oiled Wildlife Care Network at UC Davis have joined crews responding to the oil spill in Santa Barbara County. They are coordinating the wildlife response effort as part of the unified command interagency emergency response team. Network staff and faculty were called away from an oil spill conference in Alaska to respond […]

Marine life vulnerable from materials in sunscreens, boats

Nanomaterials commonly used in sunscreens and boat-bottom paints are making sea urchin embryos more vulnerable to toxins, according to a study from UC Davis. The authors said this could pose a risk to coastal, marine and freshwater environments. The study, published in the journal Environmental Science and Technology, is the first to show that the […]

Hummingbird health: Appreciating the little things

Manfred Kusch’s garden is loud, in an idyllic sort of way. Birds tweet and flit, bees buzz, and the air hums with the wings of one of America’s most beloved creatures: the hummingbird. For the past six years, Kusch, a retired UC Davis lecturer emeritus of French and comparative literature, has been opening his garden […]

Where man and nature collide: Roadkill hot spots in California

An interactive map shows how California’s state highway system is strewn with roadkill “hot spots,” which are identified in a newly released report by the Road Ecology Center at UC Davis. The data could help state highway planners take measures to protect both drivers and wildlife. The report describes data logged into the California Roadkill […]

Mountain gorillas: New insights on population decline

The first project to sequence whole genomes from mountain gorillas reveals that many harmful genetic variations have been removed from the population through inbreeding, that mountain gorillas are genetically adapting to surviving in small populations, and that they have survived in small numbers for thousands of years. The study, published last week in the journal Science, […]

Lake Tahoe water clarity is best in more than a decade

Clarity levels at Lake Tahoe in 2014 showed the biggest improvements in more than a decade, according to researchers at UC Davis, who have studied the lake for the last half-century. The improvements are in part due to continuous work from the Lake Tahoe community to reduce pollutants to the lake. They were also influenced by […]

Students lighting the way to a future career

In most classes, coursework involves sitting in front of a computer. But students in professor Michael Siminovitch’s “Design with Light” class were hard at play in February, using their hands and their imaginations to devise what could become the next big thing in lighting.

Students were preparing for the California Lighting Technology Center’s 11th annual Luminaire Design Competition, in which classmates compete against each other to create a luminaire from a lighting kit contributed by a partner in the lighting industry.

This year, the kits contained organic light-emitting diodes from Acuity Brands. OLEDs are thin, lightweight, dimmable, cool to the touch and energy-efficient. Many in the industry consider this emerging technology the future of lighting.

Secondhand smog from Asia drifts to California

Approximately 10 percent of ozone pollution in California’s San Joaquin Valley is estimated to be coming from outside of the state’s borders, particularly from Asia, according to preliminary research presented Tuesday by UC Davis. Secondhand smog from Asia and other international sources is finding its way into one of the nation’s most polluted air basins, […]

Sea change: What took decades to destroy took millennia to recover

Ocean ecosystems that experience rapid upheaval because of climate change can take thousands of years to recover, according to an examination of fossilized ocean fauna on the seafloor by UC Davis. The study, published online Monday in the Early Edition of the journal PNAS, is the first record of disturbance and recovery of seafloor ecosystem […]

$10M will help Delta smelt breeding program

Delta smelt are hard to find. Federally listed as threatened in 1993 and as endangered under the California Endangered Species Act in 2009, they are an iconic species for water issues in the state. But there’s one place where the fish can be found by the thousands — the Fish Conservation and Culture Laboratory at […]

Natural gas trucking fleet could benefit economy, but has mixed environmental effects

Switching from diesel fuel to natural gas may hold advantages for the nation’s heavy-duty trucking fleet, but more needs to be done to reach the full environmental benefits, according to a report released Wednesday by the Institute of Transportation Studies at UC Davis, and Rice University. With the so-called “shale revolution,” the recent emergence of natural gas […]
