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.

Glad to share our paper out today @NatureEcoEvo: “Serial innovations by Asgard archaea shaped the DNA replication machinery of the early eukaryotic ancestor”. www.nature.com/articles/s41... #microsky #archaeasky

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.

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...

This was fun! Folding whole proteomes… looking at tomogram, looking at genomes🤩 lots to discover!🧬🧶

Unusual protein found in a Loki Asgard Archaea.

Check out this weird protein we found in a Loki Asgard archaea.🧬🧶Only found relatives in other Lokis. 🤔

Alright, last one, now I need to get back to real work... 😸

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.

📣 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 🧵

One more appointment with great science in a few days, one click away 👇

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.

Microtubules in Asgard archaea Discovery of heterodimeric, microtubule-forming tubulins in Asgard archaea, the closest known relatives of eukaryotes, reveals snapshots of microtubule evolution.

Interesting paper alert! #eukaryogenesis www.cell.com/cell/fulltex...

SCIENCESHOTS What does a scientist look like? Children are drawing women more than ever before

When asked to draw a scientist, school-age kids in the United States are increasingly sketching women, according to a study from 2018.

Closing out our winter premier, @florianwollweber.bsky.social will tell us about his investigations into the elusive cell biology of Asgard archaea using state-of-the-art imaging techniques! Show your love for archaea by tuning in on WEDNESDAY! Remember, they're everywhere, always watching 👀
