The irregular gray shape denotes a putative wall-less archaeon that could have been the host of the alpha-proteobacterial endosymbiont, whereas the oblong red shape denotes a typical archaeon with ...

The origin of eukaryotes is considered one of the greatest enigmas in biology: according to current doctrine, two prokaryotes, a so-called Asgard archaeon and a bacterium, are believed to have merged.

The culprits are tiny, parasitic archaea of the species Candidatus Nanohaloarchaeum antarcticus that parasitize other ...

The origin of eukaryotes is considered one of the greatest enigmas in biology: according to current doctrine, two prokaryotes, a so-called Asgard archaeon and a bacterium, are believed to have merged.

In fact, a prevailing hypothesis emerging from genomic and other comparisons is that the first eukaryote actually evolved from collaboration between an archaeon and a bacterium. Scientists study ...

It’s thought the more complex cells, which we are made of, originated when a bacterium entered an archaeon. Our understanding of what is needed for life has changed. Life almost certainly ...

Graphene-based nanomaterials show promise in drug delivery, but challenges like toxicity and aggregation must be addressed ...
