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.
The mosquito-borne Zika virus is known for causing microcephaly, a birth defect in which abnormal brain development results in a smaller-than-expected head. A new study published Jan. 13 in mBio shows that the Zika virus hijacks a host protein called ANKLE2, which happens to be important for brain development, to assist its own reproduction. Because Zika, unlike most related viruses, can cross the placenta, this can have disastrous consequences in pregnancy.
The global dietary supplements market, valued at $178.8 billion in 2023, is rapidly growing. Exercise physiologist Keith Baar specializes in sports medicine and studies the effects of collagen, whey and omega-3 supplements on bone and tendon health.
Each year, nearly 30 million Americans purchase a real tree for the holidays. Growing the perfect Christmas tree takes about seven years, during which farmers need to keep insects, fungal pathogens and hungry deer at bay. While researchers suspect the distinctive piney smell the trees emit plays a role in deterring these pests, not all trees smell the same, and which chemical blends confer resistance is unclear.
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.
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:
