"Parts of the Lassen Volcanic National Park in California's Cascade Range resemble the gateway to a hellish underworld, with pools of boiling water and bubbling mud where almost nothing can live, due to scalding temperatures that can reach a blistering 464 degrees Fahrenheit. That's enough to kill a human, obviously, which rangers and ample signage helpfully point out to visitors throughout the park."
"This humble critter, a gooey-looking blobunder the microscope, has set a "new record for the upper temperature limit" for all complex organisms on Earth because it can divide at a burning-hot 145.4 degrees Fahrenheit, according to the scientists who laid out their findings in a yet-to-be-peer-reviewed study published last week. In reporting by Nature, the researchers said the existence of the once-unknown amoeba - now called Incendiamoeba cascadensis, meaning "fire amoeba from the cascades""
Lassen Volcanic National Park contains pools of boiling water and bubbling mud reaching up to 464°F, creating environments lethal to most life and humans. A newly identified single-celled organism, Incendiamoeba cascadensis, can divide at 145.4°F, establishing a new upper temperature limit for complex (eukaryotic) organisms. The existence of this fire amoeba demonstrates that some eukaryotes can survive far higher temperatures than previously recorded, challenging assumptions about heat tolerance across domains of life. Prokaryotes, including archaeans, maintain higher heat resilience, persisting in ranges between roughly 149°F and 221°F and a recorded maximum of 251.6°F for Methanopyrus kandleri.
