From improving crop production to tracking mosquitoes, the Stable Isotope Facility in the UC Davis Department of Plant Sciences supports a wide range of research on campus and throughout the world. December 1, 2017 marks the facility’s 20th anniversary and they are holding an open house today to celebrate.
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.
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.

UC Davis vector biologist Greg Lanzaro is taking part in the newly-announced UC Irvine Malaria Initiative to genetically engineer new strains of mosquitoes to fight malaria in Africa. The project, led by UCI’s pioneering vector biologist Anthony James, will bring together experts in molecular biology, entomology, public health and community engagement from across the UC system.
Home mortgage delinquencies in Bakersfield, Calif. increased 300 percent in 2007, while cases of West Nile virus almost tripled in the same year, according to a study by UC Davis entomologist William Reisen and colleagues.
The link? Neglected swimming pools and jacuzzis turning green and providing a perfect habitat for mosquitoes. More alarmingly, many of the pools were colonized Culex tarsalis, a species of mosquito usually found in more rural areas, which is better at transmitting West Nile virus than the mosquitoes it has replaced.
This aerial photo from the paper shows green and neglected pools in Bakersfield. The paper is published in the current edition of the journal Emerging Infectious Diseases.
