So happy to announce our new preprint, “A geothermal amoeba sets a new upper temperature limit for eukaryotes.” We cultured a novel amoeba from Lassen Volcanic NP (CA, USA) that divides at 63°C (145°F) 🔥 - a new record for euk growth!

Super cool update!! @rmshepherd.bsky.social was able to culture some thermophilic amoebae from our built environment steam vent samples on campus that can happily grow at at least 50C! They are most closely related to Fumarolamoeba (isolated from... yep... fumaroles!) #protistsOnSky #MicroSky

Thermophilic amoebae from Lassen Volcanic NP are happy and active today at 57C 😱😍😍 This is quite hot for euks and the current known limit for amoeboid lineages - and we suspect they may be able to withstand even higher temps... stay tuned!

Exploring the Existence of Life at 125°F
A&S biologists study the mechanisms that have allowed microbial eukaryotes to thrive in the extreme conditions of a geothermal lake.
