Steve Lindsay of the University of Durham in the United Kingdom will develop a non-invasive test to block the reemergence of malaria in disease-free regions by training dogs to identify specific odors that are released from people carrying the malaria parasite. It is known that people infected with the malaria-causing parasite Plasmodium falciparum produce thioethers in their breath, possibly to attract mosquitoes so that the parasite can spread more quickly to other people, thereby promoting malaria transmission.
