Hot-spring amoeba reportedly divides at 63°C
A science news account says Incendiamoeba cascadensis from Lassen hot springs exceeds the old roughly 60°C heat ceiling for eukaryotes—organisms whose cells contain a nucleus.
TLDR
A science news account reports that Incendiamoeba cascadensis divides at 63°C and remains mobile up to 64°C. The amoeba comes from Lassen hot springs, and the account describes those temperatures as beyond the old roughly 60°C ceiling for eukaryotes. It also says the amoeba’s cysts recover after exposure to 70°C.
