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!

🚨Check out the first blog of our GSB4 ECR series!🚨

Dr. Sabrina Sadiq discusses the path to discovering a vast diversity of viruses in Australian soils, and why we must know more!

📢Be sure to check out the talk at the #GSB4 conference in April!

Characterising Soil Eukaryotic Diversity From NEON Metagenomics Datasets
Belowground eukaryotic diversity serves a vital role in soil ecosystem functioning, yet the composition, structure, and macroecology of these communities are significantly under-characterized. The Na...

We are our best when we collaborate. 🧪🦠🔬🧬🌍🍄
This mural about the invisible #soil #biodiversity in Moers(🇩🇪) resulted from the collaboration between my friend Dr. Arne Schwelm, the people from sci:moers and the Stiftung für Umwelt und Entwicklung under the artistic direction of #cokyone.
A mural designed by members of sci:moers under the artistic direction of urban artist cokyone (https://cokyone.myportfolio.com), after the biodiversity analysis in soil done by Dr. Arne Schwelm. The organisms are a Gastrotrichia, Tardigrade, a nematode, a ciliate, a testate amoeba and the fruiting body of a fungus.

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
