Fresh from the PNAS press: A new approach to rooting the archaeal tree of life

Now available in the Early Edition of PNAS: Tom Williams (University of Bristol, UK) in collaboration with, among others, the Ettema-lab reports on using integrative modeling of gene and genome evolution to root the archaeal tree of life and to resolve the metabolism of the earliest archaeal cells. This study sheds new light onto archaeal genome evolution,

New paper published about evolution of microbial communities in subseafloor sediment

How are microbial communities assembled in the >5,000-y-old subsurface of marine sediment, and do they undergo adaptive evolution or accumulate mutations due to impaired DNA repair under such energy-limited conditions? This can be found out in the recent PNAS paper published by the Ettema-lab  in collaboration with Aarhus University and  MIT. To read the paper

New paper about the Asgard archaea and eukaryogenesis is out now!

In an international collaboration, the Ettema-lab has published a new paper in Nature about a group of archaea that gives unique insight into the evolution of cellular complexity, the Asgard archaea. Named after Nordic gods, several relatives of the previously discovered Lokiarchaeum are described in this week’s issue of Nature (paper can be found here)!  If

New paper about droplet-MDA is out!

In collaboration with the droplet microfluidics group from the Royal Institute of Technology (KTH), SciLife lab Stockholm, the Ettema-lab has published a new paper about reducing bias in whole genome amplification reactions of low biomass samples for metagenomic analyses. This improved method for whole genome amplification will allow more accurate studies of what microbial species
