This image shows a three-dimensional map of the basic structural unit in the parasite Trypanosoma brucei’s flagellum, with various mechanical and motor proteins labeled. Millions of people worldwide ...

The body's homeland security unit is more thorough than any airport checkpoint. For the first time, scientists have witnessed a mouse immune system protein frisking a snippet of an invading bacterium.
