The development of maternal egg cells is pivotal for survival – but also precarious. During meiosis, the DNA-containing chromosomes can easily be broken or lost, causing infertility, miscarriage, or genetic disorders. Scientists have struggled to study these crucial cellular events in humans and other mammals.

Rice is a staple food crop for more than half the world’s population, but most farmers don’t grow high-yielding varieties because the seeds are too expensive. Researchers from the University of California’s Davis and Berkeley campuses have identified a potential solution: activating two genes in rice egg cells that trigger their development into embryos without the need for fertilization, which would efficiently create high-yielding clonal strains of rice and other crops.

The work of 12 early-career faculty members will get a boost as this year’s class of Hellman Fellows. They will receive grants ranging from $16,000 to $49,000, for a total of $330,000 awarded.

Their work covers a wide range of topics, from the educational experiences of Venezuelan immigrants to a wireless device that monitors for seizures.

New research suggests that it could be possible to separate treatment from hallucinations when developing new drugs based on psychedelics. The anti-anxiety and hallucination-inducing qualities of psychedelic drugs work through different neural circuits, according to research using a mouse model. The work is published Nov. 15 in Science.

It’s not an exaggeration to say that this fall has seen a great many things come to pass. Whether events on the national stage, or advances in the life sciences, you’ve no doubt had a lot to watch.

If you’ve ever walked by tables of College of Biological Sciences apparel, including soft hoodies, baseball caps, t-shirts, and quarter-zips, chances are you’ve just passed by BioBoosters. The longstanding and popular student club responsible for pop-up swag sales of CBS apparel is back for the 2024-25 year with a slate of student activities, including, of course, more swag sales. 

Wolf Dietrich-Heyer, a Distinguished Professor and chair in the Department of Microbiology and Molecular Genetics was among three members of the UC Davis community recognized for their remarkable efforts to steward donors and raise the culture of philanthropy across the university. 

The Office of Development and Alumni Relations and the UC Davis Foundation presented the 2024 Faculty and Staff Stewardship Awards during a ceremony on Oct. 19. The recipients are:

A bumblebee’s brain is smaller than a sesame seed. But it can still accomplish quite a bit.

“You don’t need a big brain to learn well,” said Felicity Muth, an assistant professor in the Department of Neurobiology, Physiology and Behavior and a National Geographic Explorer who studies cognition in bees and other animals. “Bumblebees are capable of many of the same cognitive feats as many vertebrates.”

A flowering plant might not be able to tell how many fingers you’re holding up, but it can tell whether it’s light or dark outside and might grow differently if it suddenly finds itself in the shade of another plant.

Plants do that through photoreceptors, which are a major focus of research for John Clark Lagarias, a distinguished professor emeritus of molecular and cellular biology.

Photoreceptors have important uses, like measuring the length of the day; plants can tell when seasons change because the days get longer or shorter.

Sam Arcement—Director of Graduate Academic Programs for the College of Biological Sciences, and the program coordinator for the Molecular, Cellular, and Integrative Physiology (MCIP) Graduate Group—has been honored with the 2024 Outstanding Graduate Program Coordinator Award from the Office of Graduate Studies. This year saw a record number of nominations. “Sam tirelessly ensures that our needs and concerns are heard and addressed,” said one MCIP student, who praised Arcement’s dedication to student advocacy.
