CRISPR can stop malaria spread by editing a single gene in mosquitos

CRISPR gene-editing therapy has shown great potential to treat and even cure diseases, but scientists are now discovering how it can be used to prevent them as well. A team of researchers found a way to edit a single gene in a mosquito that prevented it from transmitting malaria, according to a paper published in Nature. These genetically modified mosquitos could eventually be released into the wild, helping prevent some of the 600,000 malaria deaths that occur each year.

Mosquitos infect up to 263 million people yearly with malaria and efforts to reduce their populations have stalled as late. That's because both the mosquitos and their parasites that spread malaria have developed resistance to insecticides and other drugs.

Now, biologists from UC San Diego, Johns Hopkins and UC Berkeley universities have figured out a way to stop malarial transmission by changing a single ...
