Hobbyist DNA Services May Be Open to Genetic Hacking

October 22, 2019
Professor Graham Coop and postdoctoral researcher Michael “Doc” Edge, both of the Department of Evolution and Ecology, warn that these “direct to consumer” DNA testing services could be vulnerable to a sort of genetic hacking.

Dark Centers of Chromosomes Reveal Ancient DNA

June 18, 2019
Geneticists exploring the dark heart of the human genome have discovered big chunks of Neanderthal and other ancient DNA. The results open new ways to study both how chromosomes behave during cell division and how they have changed during human evolution.

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.

Investigating the Seagrass Microbiome

March 28, 2018
Seagrass carpets the seafloor creating a unique and vital ecosystem in shallow marine environments. Sea turtles graze on seagrass leaves while smaller organisms seek refuge in the green fields but, on the microscopic level, seagrass is also home to microbial communities. Such microbes compose the seagrass microbiome and potentially play a role in seagrass ecology.
