Bacteria of the Flies: Tracing the Spread of Disease-Controlling Wolbachia

March 09, 2018
In a study appearing in Current Biology, Michael Turelli, distinguished professor of genetics in the Department of Evolution and Ecology, and his colleagues traced the spread of closely related Wolbachia across Drosophila fly species. They found that while the flies evolutionarily diverged tens of millions of years ago, their Wolbachia bacteria diverged only tens of thousands of years ago.

New Machine Learning Algorithm Finds Patterns in RNA Structures

March 01, 2018
Software inspired by speech recognition technology could help scientists understand the secret language inside cells. A machine learning algorithm called patteRNA, designed by UC Davis researchers, rapidly mines ribonucleic acid, commonly called RNA, for specific structures, providing a new method to establish links between structure, function and disease.

Why Study Bird Brains? A Video by Rebecca Calisi

November 29, 2017
Why study the brains of birds? Do birds even have brains worth talking about? In fact, birds can show complex behavior and mental function. We can learn a lot from studying the neuroscience of birds — knowledge that we can relate to how human brains function in health and disease. In this video, Rebecca Calisi Rodriguez, assistant professor of neurobiology, physiology and behavior in the UC Davis College of Biological Sciences, introduces her own work on bird brains and talks to some prominent neuroscientists about their work.

“Smart” Immune Cells: Emerging Cancer Therapy Research at UC Davis Receives a Boost with NIH Award

October 05, 2017
Assistant Professor Sean Collins, Department of Microbiology and Molecular Genetics, has received a $1.5 million award from the National Institutes of Health to advance the development of “smart” immune cells for therapies to treat cancer and other diseases. The five-year NIH Director’s New Innovator Award aims to provide new insight into how to engineer immune cells to control their recruitment and response to tumors.

Key to Regulating Cell’s Powerhouse Discovered: Fundamental Discovery Has Implications for Health and Disease

July 14, 2016
Aging, neurodegenerative disorders and metabolic disease are all linked to mitochondria, structures within our cells that generate chemical energy and maintain their own DNA. In a fundamental discovery with far-reaching implications, scientists at the University of California, Davis, now show how cells control DNA synthesis in mitochondria and couple it to mitochondrial division.

Do Zebra Stripes Confuse Biting Flies?

May 25, 2016
Zebra stripes have fascinated people for millennia, and there are a number of different theories to explain why these wild horses should be so brightly marked. A handful of laboratories around the world – including one lead by UC Davis wildlife biologist Tim Caro – have been putting these theories to the test. A new paper from Caro’s group, led by Ken Britten at the UC Davis Center for Neuroscience, puts a hole in one idea: that the stripes confuse biting flies by breaking up polarized light.
