Should we use a genetic weapon against mosquitoes carrying malaria?

T. H. Saey,  ScienceNewsExplores,  2022.
In a large laboratory cage, a male mosquito carries a genetic weapon that could launch the destruction of his species. That loss could also mean the end of the parasite that causes malaria. The weapon? A self-replicating bit of DNA known as a gene drive. It’s one of the most ...
