For many, mathematics exists solely within the confines of a blackboard, a calculator or a textbook. But ask Javier Arsuaga and he’ll tell you that mathematics exists within us, right down to our DNA.

The courtyard between Green Hall and Briggs Hall is sunny, and our trees are in full bloom. Spring is most definitely here.

And with it comes Picnic Day, the longstanding student-run UC Davis tradition, which is on Saturday, April 20. For those planning to attend, I hope you enjoy the fun and engaging activities across campus. From the parade to the doxie derby, there’s a lot to do and even more to see.

Researchers in the College of Biological Sciences have received a grant to study the role of the cerebellum in autism. “We need a more holistic understanding of the brain circuits that drive this disorder,” says Alex Nord, an associate professor of neurobiology, physiology and behavior (NPB), and a researcher at the Center for Neuroscience (CNS). “The cerebellum is a key component that has been largely overlooked until recently.”

At first glance, it might seem odd to find a former NFL kicker and a Nobel laureate sharing a stage. But Rolf Benirschke ‘77 and Charles Rice ‘74 have an unusual—and unusually consequential—bond: Benirschke is a survivor of Hepatitis C, and Rice’s research on the virus led to the cure that saved him.

Sorghum, or broomcorn, is a staple crop in sub-Saharan Africa, but approximately 20% of annual yields are lost due to infections with witchweed (Striga hermonthica), a parasitic plant that steals nutrients and water by latching onto the plant’s roots.

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.

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.

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.”

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 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.
