In a new study published in Science Advances on September 10, a team of UC Davis researchers tracked the movement of fluorescent particles inside the cells of microscopic worms, providing unprecedented insights into cellular crowding in a multicellular animal. They found that the cytoplasm inside the worms was significantly more crowded and compartmentalized than in single-celled yeast or mammalian tissue culture cells, which are more commonly used to gauge internal cellular dynamics.
The mind of a fruit fly encompasses 125,000 nerve cells, squeezed into the space of a poppy seed. At first glance, the fly brain looks nothing like a human brain. But many of the underlying neural circuits are surprisingly similar.
Fumika Hamada, a professor of neurobiology, physiology, and behavior, is using fruit flies to study a critical but oft-overlooked brain function: the regulation of our body temperature in a consistent daily rhythm.
Although teaching is a core part of being a professor, most academics learn how to teach on the job. CBS’s Future Undergraduate Science Educators (FUSE) program is changing that.
In the college, undergraduate students don’t just learn from textbooks—they actively contribute to new scientific knowledge through hands-on research. This experiential learning is a hallmark of a UC Davis education, especially in the life sciences.
For his outstanding commitment to ensuring undergraduate students have these meaningful and immersive research experiences, Chang‑il Hwang, an associate professor of microbiology and molecular genetics, has received a 2025 Chancellor’s Award for Excellence in Mentoring Undergraduate Research.
The single-celled parasite Entamoeba histolytica infects 50 million people each year, killing nearly 70,000. Usually, this wily, shape-shifting amoeba causes nothing worse than diarrhea. But sometimes it triggers severe, even fatal disease by chewing ulcers in the colon, liquefying parts of the liver and invading the brain and lungs.
Three faculty affiliated with the College of Biological Sciences are among the eight UC Davis faculty newly elected as fellows of the American Association for the Advancement of Science, announced March 27. They are: Frédéric Chédin, a professor and chair in the Department of Molecular and Cellular Biology; Dario Cantù, a professor in the Department of Viticulture and Enology; and Huaijun Zhou, a professor in the Department of Animal Science.
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.
Exercise physiologist Keith Baar specializes in sports medicine. He studies the effects of exercise on bone, muscle and tendon health.
In this Q&A, he discusses how intensive exercising after injury or when overweight can cause damage to ligaments and tendons. He also talks about the importance of integrating isometric or static exercises into our fitness routines.
