Amoebas kept dividing at scorching 63°C, study finds

Original: At California’s Lassen Volcanic National Park, researchers used barbecue tongs to reach a narrow stream. Back at Syracus

Researchers collected samples from a hot stream in California's Lassen Volcanic National Park using barbecue tongs, then raised the temperature on an amoeba in Syracuse University labs from 57°C to 60°C. At 63°C the organism was still dividing, raising questions about how its intricate cellular machinery keeps functioning under such heat. The findings shed light on the limits of life at high temperatures.

Why now: The amoeba's ability to keep dividing at extreme heat surprises people and touches on questions about the limits of life.
