George Dimopoulos is an associate professor at the Johns Hopkins Malaria Research Institute. His team used a method called transient gene silencing to change the genetic structure of the three mosquito species responsible for spreading malaria. The genetic changes cause the bodies of the insects to attack the Plasmodium parasite, blocking its development.
BOB DOUGHTY: Gregory Glass is a professor with the John Hopkins Bloomberg School of Public Health. His team used satellite imaging to observe mosquito populations in Africa. The closer one lives to places where mosquitoes reproduce, the greater the risk of getting malaria.

Professor Glass says the satellite imaging helps researchers identify which areas face the greatest risk. He says it also shows where to send much-needed medicines, insecticide products and protective mosquito nets.
FAITH LAPIDUS: The Malaria Institute at Macha in southern Zambia is a living laboratory for the study of mosquito and human behavior. There, researchers are developing a test that uses human saliva instead of blood to find those infected with malaria. The researchers say the test will make it easier to identify and contain the disease, especially in children. It would also be helpful in areas like southern Africa, where people often do not show signs of the disease.
