An Asgard archaeon of the proposed species Lokiarchaeum ossiferum

An article published in the journal “Nature” reports a study on archaea that belong to the proposed superphylum called Asgard and in particular on their characteristics that make them a possible evolutionary missing link with eukaryotes. A team of researchers formed by the collaboration of the working groups of Christa Schleper of the Austrian University of Vienna and Martin Pilhofer of ETH Zurich was successful in cultivating a species belonging to this group of microorganisms to study them in the laboratory. This allowed conducting thorough examinations of their cellular structures such as the extensive cytoskeleton.
