Blood. Red cells, white cells and platelets, liquid life. But our blood can also be just the place to invade and reproduce, with devastating results.

This work was created for the Royal Society Summer Science Exhibition (2013) and was presented in a light box. With the light off you see healthy blood. When you switch on the light, you can see the ring-form trophozoites of Plasmodium falciparum. This is the parasite that causes malaria, a leading cause of disease and death in many places in Africa and elsewhere.
