I have to go over stuff in prep for going up for full prof next year. I reconciled all the awards my mentees have gotten over the past 9 years. $709,000 worth. And that's just while they were in my lab. I am very proud of all of them!

Stavros and I picked the name of his Asgard archaeon! Skadiarchaeum cthulhuensis. We thought that if we cannot change the fact that people name microbes after fantasy characters, we should go all in.

We screened all publicly available, unrestricted metagenome and metatranscriptome datatsets on IMG/M and the SRA. This revealed the presence of several lineages of methyl coenzyme M reductase (mcr) encoding Thermoproteota in anoxic ecosystems: wetlands, wastewater, hot vents, sediments, peat, etc.

In a couple of days, my grad student Stavros Trimmer will present his new Asgard archaea culture at the GRC Archaea. He named it Skadiarchaeum after Skadi, the Norse goddess of skiing and hunting. Cartoon of Skadi based on cryoET, which was performed together with with @florianwollweber.bsky.social

I will fight every person claiming genAI is worth shit with common sense experience. It cannot even count correctly. What a fucking mess.

Manuscript/resource alert #microsky 🦠 My lab offers the community a collection of 30 E. coli (CloneFISH) cultures, each carrying a plasmid for the heterologous expression of a (near) full-length 16S rRNA gene from one of 30 lineages of archaea, including 19 yet uncultured ones.
