A Menagerie of Model Organisms

May 14, 2019
What can a worm or fish tell us about the human body? When it comes to biology, quite a lot actually. Learn how UC Davis researchers are using animal models to answer basic biological questions that will build the foundation for revolutions in human health in the new feature story "A Menagerie of Model Organisms."

From Yeast to Zebrafish, New Insight on Birth Defects and Miscarriage

January 17, 2019
In a study appearing in PLOS Genetics, Professor Sean Burgess and her colleagues highlight how mutations in a gene called spo11 can lead to zebrafish males that are infertile and females that produce offspring with developmental problems.

Wayward Ways: New Study Reveals How the Nucleus Travels

September 20, 2018
Using CRISPR/Cas9 gene editing tools, Dan Starr created mutant versions of the worm C. elegans, to explore how the nucleus moves and repositions itself in the eukaryotic cell.

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.
