Twice as Nice: College of Biological Sciences Ph.D. Students Receive U.S. Department of Energy Awards for Computational Biology Research

May 27, 2020
Keith Fraga won a Office of Science Graduate Student Research award, which gives Ph.D. students the opportunity to conduct research at a DOE national laboratory. Mary-Francis LaPorte won the DOE’s Computational Science Graduate Fellowship, which helps train next-generation leaders in computational science.

New Cryo-Electron Microscope Powers Biological Sciences Discovery

February 18, 2020
Chancellor Gary S. May and Mark Winey, dean of the College of Biological Sciences, recently cut the ribbon on a new cryo-EM facility in Briggs Hall. The $2.5 million microscope is open to all campus researchers. It can collect thousands of images a day to assemble into movies showing how proteins and other biomolecules do their work.

Mitochondrial Chitter-Chatter: Unveiling the Molecular Structures of Cellular Respiration

September 03, 2019
In order to generate energy, our bodies transfer electrons from food—sugars, fats and proteins—to molecular oxygen, which allows our cells to respire and function. Performed by the mitochondrial electron transport chain (ETC), this process creates ATP, the “molecular currency” for energy in the cell. In a Molecular Cell study, Assistant Professor James Letts, Department of Molecular and Cellular Biology, and colleagues reveal further nuances of the ETC.

Disease-Causing Nibbling Amoeba Hides by Displaying Proteins From Host Cells

April 30, 2019
A parasitic amoeba that causes severe gut disease in humans protects itself from attack by biting off pieces of host cells and putting their proteins on its own surface, according to a study by microbiologists at the University of California, Davis.

Visualizing “Unfurling” Microtubule Growth

November 13, 2018
Microtubule fibers are hollow rods made of much smaller tubulin subunits that spontaneously assemble at one end of the rod, but exactly how they do this inside the crowded environment of living cells has been a mystery. UC Davis researchers have uncovered the mechanism that puts these blocks in place, illustrated in a new animation.

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.
