Nitrogenases are enzymes that convert atmospheric N2 into ammonia, thus providing bioavailable nitrogen to living organisms. Here, Maslać et al. describe a highly thermostable, simple nitrogenase from...

Anoxic live-cell imaging shows actin-dependent crawling motility and dynamic protrusions in Asgard archaea, providing insights into cellular innovations that may have contributed to eukaryotic evoluti...

The emergence of the eukaryotes coincided with the diversification of histone proteins and their post-translational modifications by enzymes that constitute the core of eukaryotic chromatin. Yet the e...

Crawling motility is a hallmark of eukaryotic cells and requires a dynamic actin cytoskeleton, regulated adhesion, and spatially organized signalling pathways1–3. Asgard archaea (phylum Promethearchae...
