Sequencing of marine sediments finds 136 newly identified Heimdallarchaeia and several novel lineages, and indicates that Heimdallarchaeia evolved distinct metabolic capabilities from other Asgardarchaeota, in conditions that may have given rise to early eukaryotes.

The quest to fit all cellular beings in one picture frame as the universal Tree of Life (ToL) has always been a daunting task for evolutionary biologists. Over the decades, ToL has emerged from a dich...

Archaea regularly interact with bacteria but reports of archaea killing bacteria are very rare. This study shows that many archaea encode peptidoglycan hydrolases, which specifically target bacterial ...

De novo gene evolution entails the birth of new genes from previously non-coding DNA. In this Review, Bornberg-Bauer and Eicholt overview how protein-coding de novo genes are identified, the mechanist...

Dans un article publié dans Nature Ecology & Evolution, des scientifiques proposent une relecture de l’origine et

HORBEC are protein complexes involved in the regulation of redox balance and energy conservation. The authors develop a bioinformatic tool for HORBEC annotation in bacterial and archaeal genomes and r...
