The Phi Sigma Honor Society’s Gamma Delta chapter at UC Davis recognizes and celebrates the academic excellence of students in the College of Biological Sciences. In the spring of each year, select undergraduates are invited to join this distinguished community, marking a milestone in their academic journey.
Meet the eight faculty members who comprise the newest class of Chancellor’s Fellows, given to early career academics doing exemplary work in their fields. One of the new fellows, Kassandra Ori-McKenney, is a an associate professor in the Department of Molecular and Cellular Biology, and four others are affiliated with the college's interdisciplinary graduate groups.
A single set of genetic instructions produces thousands of structures in our bodies – from nerve cells that branch like gnarled oak trees, to osteoblast cells that sculpt minerals into bone. It begins with the delicate formation of sperm and eggs – which ignite the miraculous unfurling of an entire body from a single cell.
For this to happen, DNA must be precisely folded and coiled into the sperm and egg cells – creating a structure that coordinates thousands of genes, says Satoshi Namekawa, a professor of microbiology and molecular genetics.
Lee Miller vividly recalls the day in 2021 when he met a woman who had lost the function of her vocal cords. In hoarse, whispering tones she explained how her voice had been instrumental to her vocation. Losing it, she said, undercut her life’s purpose. He had to listen carefully to hear her faint words, but the lesson “was really powerful.”
It’s not what you do, it’s how readily you do it. Rapid evolutionary change might have more to do with how easily a key innovation can be gained or lost rather than with the innovation itself, according to new work by biologists at the University of California, Davis, who studied how teeth in certain fishes evolved in response to food sources and habitats.
