Picture MUST credit: Zhiqian Li, Bier Lab, UC San Diego A new method that genetically blocks mosquitoes from transmitting malaria has been developed by researchers. The flying insects are responsible for the deaths of more people each year than any other animal. In 2023, the blood-sucking bugs infected a reported 263 million people with malaria, leading to nearly 600,000 deaths, 80 percent of them children. Now, a US team drawn from the University of California San Diego, Johns Hopkins University, UC Berkeley and the University of São Paulo have created a gene-editing system that changes a single molecule within mosquitoes. This minuscule but effective change stops the malaria-parasite transmission process. Genetically altered mosquitoes are still able to bite those with malaria and acquire parasites from their blood, but the parasites can no longer be spread to other people. The new system is designed to genetically spread the malaria resistance trait until entire populations of the insects no longer transfer the disease-causing parasites. Picture supplied by JLPPA
