We stumbled upon an unusual gene called 'rqua' in the genome of some freshwater sponges. In microbes, this gene confers the ability to make a ubiquinone analog - rhodoquinone - which can help the respiratory chain run without oxygen.

Horizontal gene transfer is often depicted as a process distributing pre-existing functions to novel genetic backgrounds. Yet HGT can also increase the rate of functional innovation after transfer. Here's a brief review on the topic: ecoevorxiv.org/repository/v... #evosky #microsky

🧵 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. 🧬

Fantastic collaboration w/ @dbikard.bsky.social @audeber.bsky.social @rayanchikhi.bsky.social labs led by @jmouradesousa.bsky.social : We assessed the rates of variation of anti-phage systems in P4-like satellites and P2 helper phages. Quick conclusion: Huge variation! We focus on 4 key questions/5
The best stories are the personal ones. So before we get to the new preprint, stay awhile and listen

Check out our latest pre-print of our favourite pets - the breviates. This work was led by Zhezhen Yi in collaboration with @andrewjroger.bsky.social and many others! By studying diverse breviates we were able to see how different metabolic pathways can evolved in response to low-oxygen.
Archaea are often surrounded by bacteria. But is there ever active conflict between the two? Can archaea kill bacteria? If so, how do they do it?
Work by @romainstrock.bsky.social shows that some archaea can kill bacteria by secreting peptidoglycan hydrolases. journals.plos.org/plosbiology/...

🔥 At conferences, who asks the questions shapes who gets seen. Across 24 ID&CM meetings, women were 55% of delegates but asked 36% of questions.
💬 When women moderate or speak first, others follow.

So Nature-Springer, which absorbs several billion dollars in research funding each year, provides us with an API that attributes all citations to the first article in the volume.
Well done Springer Nature, at least I know where not to submit my next paper.
This paper has been a must! Great collaboration with @mkrupovic.bsky.social and @yifanzhou.bsky.social, a N&V by a legend of halophilic archaea tinyurl.com/yc3dcv72, and one picture of one of our expeditions to Dallol making the cover of the November issue of @natmicrobiol.nature.com
