| Description: |
A research team has isolated chemicals that target the odor receptors of Anopheles gambiae mosquitoes. In warmer climates, these bloodsuckers carry and spread diseases, including malaria, the second most deadly transmitted disease in Africa. The chemicals could one day be used to formulate a new class of mosquito repellent, potentially more powerful than Deet. The new repellent would bombard the mosquitoes with so many strong odors, it would scare them away. [Source: National Science Foundation]
