Student-Led Research Reveals “Off-Switch” for Autophagy

A chance observation in an undergraduate laboratory class has shed light on a key cleaning and recycling process carried out by all eukaryotic cells. Autophagy breaks down organelles, proteins and other molecules so their components can be reused and plays a protective role in preventing disease. However, when autophagy doesn’t work correctly, it’s associated with cancer and neurodegenerative diseases including Alzheimer’s. Previous research has uncovered how cells activate autophagy, but little is known about how it is switched off.

Discovery Hints at Genetic Basis for the Most Challenging Symptoms of Schizophrenia

Our understanding of schizophrenia has increased greatly in recent years, as studies of large groups of people have identified a multitude of genetic variants that increase a person’s risk of the disease. But each of those individual risk factors accounts for “only a very minor amount of the overall risk,” said Alex Nord, a professor of neurobiology, physiology and behavior in the College of Biological Sciences and the Center for Neuroscience.

Bestselling Book Blends Science and Storytelling to Explain How Memory Shapes Our Lives

Charan Ranganath admits he can be forgetful. This is true of most people, but most people are not leading experts on the neuroscience of human memory.

“Everybody knows I have a terrible memory,” said Ranganath, a professor of psychology and neuroscience at UC Davis, “and yet I got a Ph.D. and I publish papers all the time. I'm totally functional, so maybe the expectations we have are just wrong.”

From the Dean: A Lot Still Ahead

Sometimes I think time must be moving in fast-forward. The quarter ends in two weeks, and our students are gearing up for their final exams, which are followed by a welcome break and then it’s spring quarter — already.

Distinguished Professor Walter Leal Receives Academic Senate's 2024 Faculty Research Award

Distinguished Professor Walter Leal has made history as the first UC Davis faculty member to be honored by the Academic Senate with all three of its awards, which celebrate outstanding teaching, public service and research.

In 2020, the Academic Senate awarded Leal the Distinguished Teaching Award for undergraduate teaching, and in 2022 Distinguished Scholarly Public Service Award. Known internationally for his groundbreaking work in insect olfaction and chemical ecology, Leal's achievements have now earned him the 2024 Faculty Distinguished Research Award.

Plant Biologists Identify Promising New Fungicides

A promising new fungicide to fight devastating crop diseases has been identified by researchers at the University of California, Davis. The chemical, ebselen, prevented fungal infections in apples, grapes, strawberries, tomatoes and roses, and improved symptoms of pre-existing fungal infection in rice.

Meet the 2023-24 BioBooster Student Club Officers

BioBoosters, the student club that organizes the ever-popular sales of College of Biological Sciences apparel is back and gearing up for a quarter of swag sales, social events and networking activities.

Best known to the college community for their swag sales, which are held at pop-up booths around campus, the club sells hoodies, vests, caps, shirts and more emblazoned with the CBS logo. Proceeds help BioBoosters organize community-focused gatherings, connect with peers, and—most importantly—continue to supply comfortable, affordable swag for students, faculty and staff!

New Research Identifies Protein Integral to Sperm Development and Male Fertility

Early in the development of sperm, a strange event happens: the X and Y chromosomes condense into tight packages and are sequestered away from the other 44 human chromosomes. If any part of this process goes awry, the cells cannot mature into sperm. Researchers in the College of Biological Sciences have now identified an important link in this process — a little-known protein called ATF7IP2.
