Geologists unearth 'dinosaur dance floor'

Along the Arizona-Utah state line, geologists have found a three-fourths-acre site with prehistoric animal tracks so densely packed together, they're referring to it as a "dinosaur dance floor."

"Linking Plant Genetic Variation to Foliage- and Litter-Based Arthropod Communities"

Greg Crutsinger

122 Briggs, 12:10 to 1 p.m.

Sponsored by the entomology department

Study links alcohol use with brain shrinkage

You might want to consider your brain before knocking back another drink, and not just for fear of a hangover.

According to a study by researchers at UC Davis, Wellesley College and Boston University, the more alcohol people consume, the more their brain volume decreases.

New tests for Down syndrome have no known risks of miscarriage

Scientists have developed a new, non-invasive technique to test for Down syndrome that differs from the traditional tests that may cause miscarriages. The new procedure only requires a blood sample from the pregnant woman.

DNA of UCD:

UC Davis is one of two schools in the country with a nematology department. What's a nematode, you ask? Professor Valerie Williamson can not only tell you that a nematode is a microscopic worm, she can also tell you its DNA sequencing and the massive impact it has on the agricultural world today. Williamson is a professor of nematology, focusing her research on plant parasitic nematodes - the cause of over $50 million of plant damage in the U.S. The California Aggie sat down with her to chat about nematodes, her research and even her taste in produce.

Fly season hits California

Although the mosquito season comes to a close as the chill of winter approaches, fly season is in full swing as autumn's temperatures ideally foster their abundant breeding.

"This time of year is perfect for flies to reproduce," said UC Davis entomologist Lynn Kimsey, who heads the department of entomology. "And Davis is the perfect place."

Small fish “tracers” detect Bay mercury threats

In collaboration with the San Francisco Estuary Institute, UC Davis researchers have made headway in understanding the sources of toxic mercury in the San Francisco Bay and Delta. The findings, revealed in SFEI's annual report of the Regional Monitoring Program for Water Quality (RMP), indicate that changes in current habitat management techniques could prevent mercury from entering the food web and threatening the health of wildlife and humans.

UC Davis contributes to world’s largest science experiment

UC Davis research physicist Richard Breedon and dean of mathematical and physical sciences Winston Ko are just a couple names from a group of UC Davis faculty working on the world's largest and most powerful particle accelerator, the Large Hadron Collider.

"UC Davis was one of the very few American groups in particular that started in the very beginning," Ko said.

The DNA of UCD:

UC Davis chemistry lecturer Andreas Toupadakis came to America from Greece in 1978 to get his Ph.D. in chemistry from the University of Michigan. After teaching at several universities around the country, he found a home at UCD several years ago.

Toupadakis has more holistic extracurricular interests than your average chemistry professor - including philosophy, life planning, gardening and making his own soap.

HIV affects new populations in China

While China has a low number of HIV cases - 700,000 - for a population of 1.3 billion, the rising infection rate is cause for concern, according to a study based out of Rockefeller University.

Since 2005, the number of cases has risen by 8 percent and expanded into all provinces. Transmission is increasing especially rapidly among gay men and female prostitutes.

Study shows effect of climate change on Lake Tahoe’s tiniest residents

Climate change is triggering population booms and declines for certain types of algae in Lake Tahoe, according to a recent study from the UC Davis Tahoe Environmental Research Center.

The shifting makeup of these algae communities could affect biological and physical conditions in the lake, including the food web and water clarity.

The DNA of UCD:

Even though UC Davis is safe from a major earthquake, one member of the campus community is preparing for the world's worst. Ross Boulanger, Ph.D., is an earthquake specialist in the Civil and Environmental Engineering department. Between teaching classes and overseeing major earthquake, dam and levee studies, he recently co-wrote and published a book on liquefaction, or the damage that happens underground when earthquakes hit. But don't let that bring you down - this Canadian professor loves every quaking minute of his research and professorship!

Galaxy clusters moving toward edge of observable universe

A new study tracing the path of many galaxy clusters scattered over a wide span of sky shows that they are all moving toward one point in the universe.

The finding was unexpected and contradicts most theories about the state of the universe, said study author Dale Kocevski, a postdoctoral researcher at UC Davis.

 

UC Davis researchers identify rice protein that moderates disease resistance

Scientists at UC Davis have discovered a rice protein that plays a major role in moderating the resistance to infectious disease, a discovery that may have important medical and agricultural applications around the world.

A study led by plant pathology professor Pamela Ronald identified the protein XB15, a major player in the rice plant's immune system that stops the immune response from overreacting and damaging the plant.
