A genetic technology called a gene drive has shown promise in preventing malaria transmission by mosquitoes during lab tests in Tanzania. Researchers modified local mosquitoes to produce antimalarial proteins, demonstrating effective inhibition of parasites from infected children. The findings suggest the approach could work in the field if released.
