'Gene drive' mosquitoes engineered to fight malaria
Humans contract malaria from mosquitoes that are infected by parasites from the genus Plasmodium. Previous work had shown that mosquitoes could be engineered to rebuff the parasite P. falciparum, but researchers lacked a way to ensure that the resistance genes would spread rapidly through a wild population. In work published on 23 November in the Proceedings of the National Academy of Sciences, researchers used a controversial method called ‘gene drive’ to ensure that an engineered mosquito would pass on its new resistance genes to nearly all of its offspring— not just half, as would normally be the case. The result: a gene that could spread through a wild population like wildfire
