🧵 1/10 New paper out in
@natmicrobiol.nature.com
from my postdoc at
@mib-wur.bsky.social
! 🎉 How eukaryote-like was the archaeal ancestor of eukaryotes? Sequence searches alone can't tell us — so we used protein structure prediction to look deeper. 🧬

Prediction of eukaryotic cellular complexity in Asgard archaea using structural modelling - Nature Microbiology
A structural catalogue of the Asgard archaeal pangenome reveals hundreds of eukaryotic-like proteins that suggest a higher degree of cellular complexity in the archaeal ancestor of eukaryotes.

Just over ten years after the discovery of the first Asgard archaeal genomes, we revisit the rapid expansion of this remarkable archaeal lineage. From diverse genomes and metabolisms to eukaryotic signature proteins and the first cultured representatives.

Nou nee, dat mag niet. Een school moet een veilige plek zijn voor álle leerlingen. Dat staat ook in de wet. Het afwijzen van homoseksuele relaties geeft de boodschap dat iemand niet zichzelf mag zijn. Dat mag niet én is ronduit schadelijk.
