Taking aim at a key malaria molecule : Measuring the parasite’s heme levels could help scientists develop better antimalarial drugs.

A team of MIT biological engineers has developed a method to measure levels of the iron-containing protein heme inside the malaria parasite. “One of our long-term goals is ultimately being able to tie insights from these studies back to thinking about drug discovery and targeting pathways that regulate heme,” says Jacquin Niles, an MIT associate professor of biological engineering.
