Research Article by CE Terry et al. Antagonistic effects of #hypersalinity on #heattolerance in a copepod emerge from nonadditive protein abundance changes

A newly discovered #species of #amoeba, a single-celled #eukaryote, surpasses the #heattolerance #record previously held by #protists, making it an intriguing model for #astrobiology. This field of science investigates which celestial bodies with #extreme #environmentalconditions might nevertheless harbor evolved #life.
Does life exist on any of the icy #moons orbiting #Jupiter or #Saturn? Saturn’s moon #Titan, for instance, possesses two distinct biospheres where life could potentially exist: methane lakes on the surface and deep-seated water oceans that extend down to the rocky core, environments where hydrothermal vents could serve as hotspots for the evolution of life, much like on Earth. On Earth, too, the evolution of life as we know it is linked to heat; "#blacksmokers", seafloor vents, are considered cradles of terrestrial life. But is it possible to withstand even higher temperatures? Consider our neighbor, #Venus, which is closer to the Sun. The possibility of life existing somewhere in its atmosphere cannot be ruled out, though temperature tolerance would be a fundamental requirement. We no longer need to rely on theoretical models to hypothesize how organisms with extreme heat tolerance function; instead, we can study this directly on Earth using a very real species. The amoeba #Incendiamoeba #cascadensis (#Echinamoebidae, #Amoebozoa, #Eukaryota) was discovered in the hot waters of Lassen #VolcanicNationalPark in #California and tolerates temperatures of up to 63°C for #reproduction and almost incredible 64°C while still actively #foraging.
In experiments, the authors H. Beryl Rappaport et al. (2026) observed that this new species, which also represents a new genus, remains capable of cell division even at 63°C. This is particularly noteworthy, especially given that the organism belongs to the eukaryotes, a lineage that includes us humans and is characterized by highly complex cellular structures. An isolated #nucleus and the presence of #organelles are the key evolutionary innovations (#apomorphies) of eukaryotes. The newly discovered species is remarkable because, for the majority of known nucleated organisms, heat is lethal, causing #protein #damage and #membrane #destruction.

A tiny amoeba broke complex life’s heat record and could broaden the search for habitable worlds. 🔥
NASA-supported researchers found the first known eukaryote able to reproduce at 145°F (63°C), hotter than scientists thought complex cells could withstand. https://t.co/nzSSRragDR
