To carefully determine the phylogenetic position of the novel Asgard lineages in relation to other Archaea and to eukaryotes, we performed various in-depth phylogenomic analyses of concatenated rRNA ...

The sun has just set on a quiet mudflat in Australia’s Northern Territory; it’ll set again in another 19 hours. A young moon looms large over the desolate landscape. No animals scurry in the waning ...

Previously, chemists have managed to create artificial cell walls and developed synthetic DNA to produce self-replicating, synthetic bacterial cells. Now, for the first time, researchers have used ...

New studies revise ideas about the symbiosis that gave mitochondria to cells and about whether the last common ancestor of all eukaryotes was one cell or many. Our planet formed a little over 4.5 ...
