New paper alert!
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.

How common is multicellularity in bacteria? And archaea?
And how does it evolve?
We wrote a short review "On the architecture and evolution of prokaryotic multicellularity".

love when there's an article about how life is sustainable in the superheated waters surrounding a hydrothermal volcanic fissure on the ocean floor and then like six paragraphs in you find out the author's parents are chemosynthetic bacteria ๐
New preprint about closely-related #methanogens living inside ciliates and animal guts!!
We found that ciliate symbionts are functionally indistinct from free-living spp, while gut symbionts have streamlined genomes encoded for scavenging. read on if you're curious why ๐ค #ProtistsOnSky #SymbioSky
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.
