Mosquitoes engineered to zap ability to carry malaria

Efficacy test of gene drive shows it works better in males than females

BLOCKING MALARIA  Anopheles stephensi (pictured) is responsible for about 12 percent of malaria cases in India. Researchers have now engineered these mosquitoes to spread malaria resistance instead of disease.

A new genetic engineering technique may quickly inoculate mosquitoes against malaria, helping to end the spread of the disease in humans.
