Chris Vogel, a research professor in the Department of Environmental Toxicology, is a 2020 laboratory safety award winner for his oversight of a laboratory focused on environmental and molecular toxicology.

Vogel was selected for the exceptional management of his lab, which is part of the Center for Health and the Environment (CHE). The Safety Services Lab Safety Awards are endorsed by the faculty-led Chemical and Lab Safety Committee and are given to scientists in individual units throughout UC Davis.

A new method for estimating the biological sex of human remains based on reading protein sequences rather than DNA has been used to study an archaeological site in Northern California. The protein-based technique gave superior results to DNA analysis in studying 55 sets of human remains between 300 and 2,300 years old. The work is published July 17 in Scientific Reports.

Previous exposure to the pollutant DDT may contribute to the risk of diabetes among Asian Indian immigrants to the United States, according to a study from the University of California, Davis.

Sixteen UC Davis researchers have been named in the annual Highly Cited Researchers 2019 list released by the Web of Science Group, which compiles statistics on scientific publishing. The list identifies scientists and social scientists who have published multiple papers ranking in the top 1 percent by citations in a particular field and year, over a 10-year period. 

Citation counts represent how often a particular paper has been cited in other scientific publications. 

UC Davis researchers included in this year’s list are:

DNA evidence has revolutionized forensic science in the past few years, cracking open cold cases and bringing both convictions and exonerations. The same techniques help archaeologists and anthropologists studying remains from ancient peoples or human ancestors. 

But DNA is a relatively fragile molecule that breaks down easily. That’s where proteomics, the new science of analyzing proteins, comes in. By reading the sequence of amino acids from fragments of protein, scientists can work backwards to infer the sequence of DNA that produced the protein. 

How Genetics, Resources and a Long-Distant Relative Helped One Lucky Fish Species Adapt to Extreme Pollution

The combination of a big population, good genes and luck helps explain how a species of fish in Texas’ Houston Ship Channel was able to adapt to what normally would be lethal levels of toxins for most other species, according to a study to be published May 3 in the journal Science. 

Ron Tjeerdema named to NAS committee on dispersants for oil spills

Ronald Tjeerdema, CA&ES Associate Dean for Environmental Sciences, has been named to a select committee for the National Academy of Sciences (NAS) that will evaluate the use of dispersants in future oil spills.

 “I am looking forward to contributing my 30 years of experience in oil spill research,” said Tjeerdema, who is a professor in the Department of Environmental Toxicology and also holds the Donald G. Crosby Endowed Chair in Environmental Chemistry.

What can we learn from a fish that adapts quickly to lethal levels of pollution?

Evolution is working hard to rescue some urban fish from a lethal, human-altered environment, according to a study led by the University of California, Davis, and published Dec. 9 in the journal Science.
