Researchers using a combination of artificial intelligence and community-driven science may have identified the first-ever presence of Anopheles stephensi—a highly invasive malaria-carrying mosquito—in Madagascar. A photo submitted by a citizen from Antananarivo via NASA’s GLOBE Observer app was analyzed with AI algorithms, which classified the larva with more than 99% confidence. The species’ potential arrival in Madagascar raises alarm due to its adaptability to urban settings and artificial containers.
