Malaria

Female mosquitoes searching for a meal of blood detect people partly by using a special olfactory receptor to home in on our sweat. The finding could lead to new approaches for better repellents.

Scientists demonstrate that a "gene drive" can rapidly spread a genetic mutation through a species, perhaps providing a potent new weapon against malaria. But there are plenty of skeptics.

Engineers in California are working on a new test that could offer a fast, cheap way to see if people are infected with the parasite.
