Microbes Make Chemicals for Scent Marking in a Cat

September 13, 2019
A new study from the Genome Center at the University of California, Davis, shows that many odiferous compounds from a male cat are actually made not by the cat, but by a community of bacteria living in the anal sacs.

VIDEO: Building Mini-Organs to Fight Pancreatic Cancer

September 10, 2019
Assistant Professor Chang-il Hwang, Department of Microbiology and Molecular Genetics, studies pancreatic cancer, one of deadliest cancers. Learn more about how Hwang and his lab colleagues are fighting pancreatic cancer with the help of organoids.

Giraffe, Gemsbok Genome Assemblies Add to Map of Life

August 12, 2019
The genomes of wild animals can help us understand how they have adapted to unique situations, give insight into their evolution and help in efforts to protect or restore endangered species. Two examples are recently published chromosome-scale genome assemblies for the Masai giraffe and the gemsbok.

The Art of Harm Reduction: Sid Ganesh Searches for Substance Use Solutions

August 02, 2019
If you strolled through the ARC Pavilion during the 30th annual Undergraduate Research, Scholarship and Creative Activities Conference last spring, you’d find students from across campus displaying their latest research and projects. Among the mingling academics, you’d also find Sid Ganesh and three of her watercolor paintings.

The Repellence Cocktail: Mosquito Sense of Smell Reveals More Mysteries

August 01, 2019
While we know certain plant-derived compounds act as insect repellents, much of the molecular science behind insect olfaction remains a mystery. In a study published in iScience, UC Davis researchers exposed further layers of complexity in the mosquito olfactory system.

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.

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."

Engineering a Balanced Diet? Hormone FGF21 Promotes Protein Preference

May 13, 2019
In a study appearing in Endocrinology, Associate Professor Karen Ryan and her colleagues identified the hormone fibroblast growth factor-21 (FGF21) as a control for regulating dietary protein intake in male mice. They found that male mice injected with the hormone increased their intake of dietary protein over carbohydrates and fats.

Discovering Curiosity: Fighting Neuromuscular Disorders with New Faculty Lucas Smith

April 05, 2019
In his new lab at UC Davis, Assistant Professor Lucas Smith, Department of Neurobiology, Physiology and Behavior, investigates how the accumulation of scar tissue affects muscle mechanics. His aim is to develop therapies that alleviate neuromuscular disorders and restore healthy muscle regeneration.

The Language of Biology: How the Heck Do Scientists Assemble a Genome?

March 14, 2019
The genome—the complete suite of an organism’s DNA and genes—is likened to a blueprint for life. On the surface, this comparison provides some understanding of a biological concept. But according to some scientists, it misses the mark.
