A tiny, single-celled organism can thrive at temperatures that would kill all other known complex life. In a study published in Cell, scientists describe a new species of amoeba that can eat and reproduce in hot spring water as warm as 63°C (145°F) in California's Lassen Volcanic National Park. The amoeba can protect itself at temperatures up to 70°C (158°F) by changing shape and forming a protective outer layer.
