Malaria Parasite (image) DOE/Lawrence Berkeley National Laboratory Caption As shown in this X-ray image taken at Berkeley Lab's Advanced Light Source, the malaria parasite develops inside red blood cells, where it accumulates iron. It is vulnerable to the oxygen-based free radicals released by a powerful but scarce antimalarial drug known as artemisinin.
