Pre-print available: Comparison of metagenome-assembled and single-amplified genomes

This collaborative study of the Pinhassi-Lab (Linnaeus University, Kalmar), the KTH Royal Inst. of Technology (SciLifeLab, Stockholm) and the Ettema-Lab can now be read as early pre-print at bioRxiv. The paper reports on the comparison of two culture-independent strategies for recovering bacterial genomes: single-amplified genomes and metagenome-assembled genomes, and its implication for in-depth analyses of uncultivated prokaryotic taxa. Read the paper here. /MS

Nature Microbiology Review is celebrating 40 years of Archaea!

For the 40th anniversary celebration of Archaea at Nature Microbiology Review Ettema Lab is honoured to contribute not only with a review paper but also the cover of this special Dec issue! Our review presents a comprehensive overview regarding the current view of how eukaryotes have evolved from an archaeal ancestor. Join us in the celebration of Archaea

40 YEARS OF ARCHAEA Snapshot: Dr. Thijs Ettema

Nature Microbiology celebrates the 40th anniversary of the seminal publication by Carl R. Woese and George E. Fox with a “40 years of Archaea” channel to reflect on key advances in the field since its inception and discuss what the future may bring. Part of this channel is an interview by senior editor Claudio Nunes-Alves with Thijs Ettema about his experiences in working

Just published: Functional reconstruction of a eukaryotic-like ubiquitylation cascade from an uncultured archaeon

The latest publication of the Robinson-lab (Lancaster University, UK) in collaboration with the Ettema-lab is now available online at Nature Communications, regarding the ‘Functional reconstruction of a eukaryotic-like E1/E2/(RING) E3 ubiquitylation cascade from an uncultured archaeon’ – the first time that the ubiquitination cascade has been demonstrated outside of eukaryotes.  You can read the article here. /MS

Daniel Tamarit joins Ettema-lab

Starting October Ettema-lab welcomes Daniel Tamarit as its newest Postdoc. Daniel defended his PhD one year ago at Siv Andersson’s lab (UU), studying genome evolution in host-associated bacteria. Since then, he has performed evolutionary analyses on a bacterial gene transfer system evolved from domesticated bacteriophages, and on the architecture of bacterial chromosomes. Starting this week, as an integral

Standard and best practices for reporting genomes from metagenomes and single cells

Recently published in Nature Biotechnology Ettema-lab is part of an international cooperation to present two standards developed by the Genomic Standards Consortium (GSC) for reporting bacterial and archaeal genome sequences. The standards are the Minimum Information about a Single Amplified Genome (MISAG) and the Minimum Information about a Metagenome-Assembled Genome (MIMAG), including, but not limited to,

Science review: Genomic exploration of the diversity, ecology, and evolution of the archaeal domain of life

Ettema-lab is pleased to announce the recently published Science review ‘Genomic exploration of the diversity, ecology, and evolution of the archaeal domain of life’. Archaea are prokaryotes that make up a third branch of the tree of life. Knowledge of archaeal biological diversity and their role in evolution has rapidly expanded in the past decade. Despite the

Just in time for summer: our new postdoc William Lewis

It’s time to announce William Lewis as the newest member of Ettema-lab! Will recently completed his PhD in Martin Embley’s lab (Newcastle University, UK) where he studied the evolution of hydrogenosomes (anaerobic mitochondria that make hydrogen) from several species of ciliates. Starting his first postdoc here in Ettema-lab his work will involve the exploration of poorly described archaeal lineages and
