Connecting tubes between bacteria and a kind of microbe called archaea may reflect a symbiotic relationship that led to complex cells more than 2 billion years ago

Weird microbial partnership shows how complex life may have evolved

So excited to finally show the world a project years in the making. A huge group effort with lots of expertise leading to a unique #Asgard syntrophy story. Very fortunate to have been involved in cultivating and analysing this wonderful organism ❤️

Our new preprint with a new #Asgard from stromatolites (and its Desulfobacterota companion). Complete circularised genomes of both, cool #cryoem images, protein modelling, etc

An Asgard archaeon from a modern analog of ancient microbial mats

It has been proposed that eukaryotic cells evolved via symbiosis between sulfate-reducing bacteria and hydrogen-producing archaea. Here we describe a highly enriched culture of a novel Asgard archaeon...

Single-celled organisms called archaea aren't generally thought to cause human disease, but one species has been implicated in colorectal cancer

Weird 'harmless' microbes may play a pivotal role in colorectal cancer

Evolution, structure and membrane remodelling function of the ESCRT-III superfamily in eukaryotes and their closest relatives Asgard archaea. The two subfamilies, B-type and A-type, have distinct structural properties to perform sequential steps of the membrane remodelling pathway.

Would you expect that Bacteria use an archaellum for swimming? We didn't, but we found that some Chloroflexota do! Find the story here: www.biorxiv.org/content/10.1...

Horizontal gene transfer of the functional archaellum machinery to Bacteria

Motility in Archaea is driven by a nanomachinery called the archaellum. So far, archaella have been exclusively described for the archaeal domain; however, a recent study reported the presence of arch...
