Geothermal Amoeba Sets New Upper Temperature Limit for Eukaryotes at 63°C

Researchers have discovered a novel geothermal amoeba, Incendiamoeba cascadensis, that divides at 63°C (145.4°F), establishing a new record for the upper temperature limit across all eukaryotes. The study used growth experiments, expansion microscopy, and high-temperature live-ce
