“Cellular Memory” of DNA Damage in Oocyte Quality Control

September 27, 2018
During oocyte quality control, a decision is made whether each oocyte should continue and join the reserve of eggs or undergo cellular death. New research from Neil Hunter’s laboratory at UC Davis reveals the surprising way that this critical oocyte quality control process works.

Wayward Ways: New Study Reveals How the Nucleus Travels

September 20, 2018
Using CRISPR/Cas9 gene editing tools, Dan Starr created mutant versions of the worm C. elegans, to explore how the nucleus moves and repositions itself in the eukaryotic cell.

Perfect Chemistry: CBS Faculty Are Partners In and Outside the Lab

May 21, 2018
After a long day of teaching and research, biochemists Richard McKenney and Kassandra Ori-McKenney usually find themselves on their patio discussing topics like the cytoskeleton and motor proteins. It’s shop talk for the couple, both assistant professors in the Department of Molecular and Cellular Biology.

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.

Discovering Curiosity: Learning Genetics through Family Illness with Mark Winey

May 02, 2018
Mark Winey, dean of the College of Biological Sciences at UC Davis, became fascinated by science at an early age. But the draw to biology—specifically, genetics—was prompted by Winey’s younger sister Christine, who as an infant was diagnosed with an inherited metabolic disease called galactosemia.

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.
