COVER Colored scanning electron micrograph of the mouthparts of a female Anopheles gambiae mosquito. Sheathed in a scaly lower lip ending in two hairy lobes (blue) are a pair of saw-toothed stylets (green) used to cut into the skin. Because only female Anopheles blood feed, only females transmit malaria—a disease that claims the lives of more than half a million children each year.
