In a study published in the journal Cell Host and Microbe, researchers show that the malaria parasite Plasmodium falciparum uses a protein on its surface as a molecular pump to push out sodium ions, and that a newly discovered antimalarial drug kills the parasite by blocking the salt pump. Professor Kiaran Kirk, one of the researchers of the study, explains the research to Deutsche Welle in this interview. [NBC News via Reuters, Deutsche Welle]
