Scientists have determined the evolutionary timeline for the microscopic parasites that cause one of the world’s most widespread infectious diseases: malaria. Here, we see a colorized electron micrograph of red blood cell infected with malaria parasites (blue). The small bumps on the infected cell show how the parasite remodels its host cell. Uninfected cells (red) have smoother surfaces. Credit: NIAID/RML Learn more at NSF’s website devoted to science outcomes, SEE Innovation.
