Mapping Cells in the “Immortal” Regenerating Hydra

July 25, 2019
In a study appearing in Science, Assistant Professor Celina Juliano, Department of Molecular and Cellular Biology, and her colleagues used single-cell sequencing techniques to explore the genetic trajectory for nearly 25,000 cells of the immortal Hydra.

The Infection Heist: How Social Viruses Team Up for the Perfect Score

July 11, 2019
Much like characters in a bank heist, viruses in competitive environments can collaborate for their share of the "score" of successfully co-infecting hosts. But these relationships may change once inside the host cell, according to Assistant Professor Samuel Díaz-Muñoz​.

Model Organisms

For thousands of years, animals have helped humans advance biomedical research. From yeast and worms to fruit flies and mice, these creatures hold clues to the secrets of our own biology.

“Model organisms, in general, are useful because evolution doesn’t reinvent the wheel when it goes to a different species,” says Associate Professor Bruce Draper, Department of Molecular and Cellular Biology. “It keeps to using loosely the same genetic modules to build on things.”

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.
