Serial innovations by Asgard archaea shaped the DNA replication machinery of the early eukaryotic ancestor - Nature Ecology & Evolution
Phylogenetic and biochemical analyses show a diversity of components of the DNA replication machinery in different Asgard archaea that contributed to the eukaryotic DNA replication machinery.

Check out this awesome work by Strock et al. on how Archaea can turn nasty against Bacteria. Very honored for the opportunity to spread their story in a primer with @apapageorgiou.bsky.social.

Thrilled to start as Junior Group Leader
@ibotcz.bsky.social
this Sept at Průhonice! 🌿🚀
We will explore how #genomesize, #polyploidy & #traits shape plant #diversity, #evolution & #distribution across space and time, combining lab work and modelling.🌴🔬🧬
Funded #PhD openings soon! Get in touch!

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...

📣 We are proud of the publication of the second paper of @bbaker24.bsky.social PhD thesis. In collaboration with friends in Halifax we have studied the difficult question of the phylogeny of the DPANN archaea, composed of several phyla of highly reduced, fast-evolving epiparasites 🧵

Phylogenomic analyses indicate the archaeal superphylum DPANN originated from free-living euryarchaeal-like ancestors
Nature Microbiology - Phylogenetic reconstructions with conserved protein markers from the 11 known DPANN phyla reveal their monophyletic placement within the Euryarchaeota.

It's publication day of my first book: The Tree of Life. The tree of life is a time machine that can take us back 4 billion years to meet our most distant ancestor. It is the magic that lets us tell the origin stories, beginning with this ancient relative, of everything from mushrooms to man.
