Cellular organisms can be divided into two basic types of cells: the prokaryotic cells of Bacteria and Archaea and the eukaryotic cells. The rapidly expanding knowledge of the diversity and ultrastructure of prokaryotic cells has revealed cellular intricacies that warrant a critical reappraisal of the profundity of the prokaryote–eukaryote divide.

SyeA was present in the Buchnera ancestor, is secreted into the host cytoplasm, is homologous to secreted effectors of bacterial pathogens and is essential for Buchnera transmission.

Asgard archaeal mini microtubules suggest an archaeal origin of eukaryotic microtubules.

Integrated palaeontological, sedimentological and geochemical analyses of ancient rocks from Australia show that early eukaryotes were largely restricted to oxygenated benthic habitats, probably posse...

NIAID’s Integrated Research Facility is one of the few federal facilities charged with studying Ebola. Tuesday afternoon, all of its work was put on indefinite pause by Robert F. Kennedy Jr.’s departm...

Re-analysis of over 92,000 metagenomes reveals hundreds of thousands of previously undescribed Bacterial and Archaeal clades hidden in plain sight.

Modern Asgard archaea in marine sediments have the potential to respire oxygen, genomic analysis suggests.

Sequencing of marine sediments finds 136 newly identified Heimdallarchaeia and several novel lineages, and indicates that Heimdallarchaeia evolved distinct metabolic capabilities from other Asgar...

A structural catalogue of the Asgard archaeal pangenome reveals hundreds of eukaryotic-like proteins that suggest a higher degree of cellular complexity in the archaeal ancestor of eukaryotes.

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.
