Fire amoeba divides at 63 C, setting heat record for complex cells

A California hot-spring amoeba reproduces at 63 C (145 F), a record for complex cells. It still moves at 64 C (147 F), but does not reproduce there.

An amoeba from a California hot spring reproduces at 63 C (145 F), a heat record for organisms with complex cells. It still moves at 64 C (147 F), but researchers observed reproduction only up to 63 C.
