Popular Science reports that scientists have figured out how to genetically prevent mosquitoes from spreading malaria, and that much of the effect is caused by reducing the mosquito's lifespan, since the malaria parasite needs a certain amount of time to develop.  My question is this:  If scientists can reduce the lifespan of mosquitoes, why don't they simply reduce the lifespan to zero?  Mosquitoes are a worthless bunch of jerks. #science
