Hydra and the Quest to Understand Immortality

January 04, 2018
The Hydra, a small freshwater invertebrate, is an advantageous model organism for regenerative biologists. Named after the serpent from Greek mythology that grew two new heads for each one cut off, this tiny, jellyfish-like creature holds within its genomic code the key to biological immortality.

Mice Help Find Gene for Bad Breath

December 18, 2017
An international team of researchers has identified a cause for chronic bad breath (halitosis), with the help of gene knockout mice from the UC Davis Mouse Biology Program. The results are published Dec. 18 in the journal Nature Genetics.

Long-Lived: Remembering Melvin Green, A UC Davis Genetics Pioneer

December 11, 2017
Melvin M. Green, distinguished professor emeritus of molecular and cellular biology, was a geneticist and member of the National Academy of Sciences. Green co-founded the historic UC Davis Genetics Department (now part of the Department of Molecular and Cellular Biology). He passed away on Tuesday, Oct. 24, 2017, at the age of 101.

Creating Research Opportunities in the Calisi Lab, One Undergraduate at a Time

October 25, 2017
To encourage students to gain hands-on experience, Assistant Professor Rebecca M. Calisi Rodríguez, Department of Neurobiology, Physiology and Behavior in the College of Biological Sciences, launched the Calisi Lab Undergraduate Research Program. Relying heavily on philanthropic support, the program employs students as researchers in animal science, neuroendocrinology and reproductive behavior. Calisi Rodríguez’s goal is to make sure students don’t sacrifice research opportunities to make ends meet.

Zebrafish Reproductive Development May Hold Insights into Ovarian Cancer

October 23, 2017
With funding from the National Institutes of Health and the National Science Foundation, Associate Professor Bruce Draper, Department of Molecular and Cellular Biology, is studying zebrafish (Danio rerio) to learn about the genetics of sexual reproduction in vertebrates. Draper’s research, published in PLOS Genetics with postdoc and Dena Leerberg, ’17 Ph.D., may advance discoveries into the origins of ovarian cancer.

Stacey Harmer Shines On with College of Biological Sciences Faculty Research Award

August 19, 2017
When it comes to plant rhythms, Stacey Harmer, a professor of plant biology at the University of California, Davis, is hip to the groove. Her research, which appeared in the August 5, 2016 journal of Science, describes how sunflowers track the sun, beginning each morning with their heads facing east, slowly swinging west throughout the day and then resetting eastward at night.
