UC Davis Joins DARPA-funded “Safe Genes” Program

Initiative Aims to Support Responsible CRISPR Gene Editing

By Trina Wood

The federal Defense Advanced Research Projects Agency (DARPA) last week announced the Safe Genes program to explore innovative genetic techniques to support bio-innovation and combat biological threats. The effort, supported by a $65 million grant from DARPA over four years, aims to harness gene editing tools in a safe, responsible manner to maximize the benefits of these technologies while minimizing their inherent risks.

Control of Dengue Fever With Bacteria-Infected Mosquitoes

Virus-suppressing Bacteria Could Control Transmission by Mosquitoes

Mosquitos infected with the bacteria Wolbachia are significantly worse vectors for dengue virus, but how to establish and spread Wolbachia in an urban mosquito population is unclear. A study published May 30 in the open access journal PLOS Biology shows that over time, strategic releases of mosquitoes infected with the dengue-suppressing bacteria may be enough to allow the virus-resistant insects to spread across large cities.

Leading the work are Professor Michael Turelli, UC Davis Department of Evolution and Ecology, and colleagues from Scott O’Neill’s “Eliminate Dengue Program” based at Monash University, Melbourne.
