American scientists have created genetically altered mosquitoes that cannot infect humans with malaria.
The scientists from the University of Arizona introduced a gene that affects the insect's gut, rendering it incapable of sustaining the malaria parasite.
The study appears in the journal Public Library of Science Pathogens.
The researchers hope to eventually introduce the genetically altered mosquitoes into the wild in hopes of wiping out the disease-carrying insects.
Nearly 250 million people worldwide are infected with malaria every year.
