Scientists develop new gene drive with a built-in genetic barrier

New CRISPR Tools Help Contain Mosquito Disease Transmission


New CRISPR Tools Help Contain Mosquito Disease Transmission
Since the onset of the CRISPR genetic editing revolution, scientists have been working to leverage the technology in the development of gene drives that target pathogen-spreading mosquitoes such as 
Anopheles and 
Much less genetic engineering has been devoted to 
Culex genus mosquitoes, which spread devastating afflictions stemming from West Nile virus the leading cause of mosquito-borne disease in the continental United States as well as other viruses such as the Japanese encephalitis virus (JEV) and the pathogen causing avian malaria, a threat to Hawaiian birds.
University of California San Diego scientists have now developed several genetic editing tools that help pave the way to an eventual gene drive designed to stop  ....

As the health of ecosystems in regions around the globe declines due to a variety of rising threats, scientists continue to seek clues to help prevent future collapses.
A new analysis by scientists from around the world, led by a researcher at the University of California San Diego, is furthering science s understanding of species interactions and how diversity contributes to the preservation of ecosystem health. ....
