Using DNA Databases to Track Down the Golden State Killer Suspect

May 08, 2018
It’s been widely reported that investigators got a break in the East Area Rapist/Golden State Killer case when they uploaded a DNA profile to a genealogy database, GEDmatch, and identified relatives of the suspect, Joseph DeAngelo. Did they get lucky, or did they have a good chance of finding him? UC Davis population biologists Graham Coop and M. D. “Doc” Edge have written a nice explainer of the science behind this search.

Bacteria of the Flies: Tracing the Spread of Disease-Controlling Wolbachia

March 09, 2018
In a study appearing in Current Biology, Michael Turelli, distinguished professor of genetics in the Department of Evolution and Ecology, and his colleagues traced the spread of closely related Wolbachia across Drosophila fly species. They found that while the flies evolutionarily diverged tens of millions of years ago, their Wolbachia bacteria diverged only tens of thousands of years ago.

Feeding the Future

UC Davis researchers are exploring the survival strategies of wild and parasitic plants to help cultivate the climate-resistant food crops of tomorrow by Greg Watry To meet a projected population of 9.8 billion by 2050, global food production needs to grow an estimated 70 percent. Rising patterns of extreme weather are challenging food security. To adapt and feed the world, we need stronger crops. A Shifting Environment

Glaciers are melting, sea levels are rising, wildfires are blazing and droughts are intensifying. Our earth is in an alarming state of flux.

Guardians of the Genome

February 26, 2018
For many, breast cancer is more than just a disease – it’s personal. One in eight women will be diagnosed with breast cancer at some point in their lives. But through new discoveries at the genetic level, the personal nature of cancer will eventually be what helps to beat it.

Mice Help Find Gene for Bad Breath

December 18, 2017
An international team of researchers has identified a cause for chronic bad breath (halitosis), with the help of gene knockout mice from the UC Davis Mouse Biology Program. The results are published Dec. 18 in the journal Nature Genetics.
