The Hunt for the Brain-Eating Amoebas of Yellowstone

It was a lovely September day in Yellowstone’s Boiling River, which was not, in fact, boiling. Tourists trundled through the shallow water and dipped in where it was deeper. A herd of elk even waded through unconcerned. And among it all, a team of researchers in waders sampled the water for a brain-eating amoeba that kills 97 percent of the people it infects.
