Databases may contain lots of misannotated 16S rRNA sequences, which can hinder accurate taxonomic assignment in metabarcoding and metagenomic analyses. We have addressed this issue for Asgard archaea and generated a curated set of high-quality 16S rRNA sequences: academic.oup.com/ismecommun/a...

Check out our paper on intricate nested interactions between viruses and virus satellites of haloarchaea and their nanosized DPANN symbionts. Excellent collaboration with @deemteam.bsky.social, @anagtz.bsky.social and Michail Yakimov Free access link: rdcu.be/eLtCH 🧵 by @yifanzhou.bsky.social 👇

Some flamingos and other aquatic birds in the 3676 m high Salar de Aguas Calientes, near the volcanos of the Lullaillaco National Park in Chile.

Walking to our sampling point on a vast microbial mat (pink-salmon areas) in Laguna Azufrera, with the fumaroles of the Lastarria volcano visible on the horizon.

(1/2) Preprint alert! In collaboration with @yifanzhou.bsky.social and @mkrupovic.bsky.social we describe host-parasite layers in hypersaline systems of the Danakil Depression. Haloarchaea host nanohaloarchea and both are infected by viruses (12 new families found). www.biorxiv.org/content/10.1...

Did you miss our latest work on hypersaline and chaotropic ecosystems in the Danakil depression, where microbial communities harbour up to 99% of archaea? Go check what life looks like in these unique places: www.nature.com/articles/s41... @deemteam.bsky.social

Extremely acidic proteomes and metabolic flexibility in bacteria and highly diversified archaea thriving in geothermal chaotropic brines - Nature Ecology & Evolution

Metagenome analysis of microbial communities from the Danakil Depression shows that haloarchaea and Nanohaloarchaeota dominate these life-limiting salt-saturated conditions and that these archaea have...
