Malaria kills anywhere from 1 to 3 million people a year, almost all in the Third World. The death toll is projected to double in the next two decades. Discoveries that reduce its impact are likely to have vast implications for public health.

Recently, researchers genetically engineered a mosquito that is 80 percent less likely to pass on malaria to its victims. Previously, the spread of malaria could be countered only by using either drugs or pesticides. Mosquitoes can develop immunity to both, and the most effective kinds of pesticides (like DDT) make many governments squeamish.

Ito and his co-authors report that they added a gene to mosquitoes which prohibits malaria transmission from the point where a mosquito takes in its blood meal to where it ordinarily transfers the ...
