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
Big group effort with a lot of people involved

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...
