Parasitic bacteria feeding on their hosts’ RNA!? New cultures and Patescibacteriota/Minisyncoccota/CPR continue to surprise us… www.biorxiv.org/content/10.6...
A representative of a ubiquitous bacterial lineage parasitically feeds on host RNA
Cellular metabolism is widely understood as an integrated network of redox reactions, energy conservation, and biosynthetic pathways. Here we show that across diverse prokaryotic lineages, loss of red...

New isolates from eukaryote's closest archaeal relative: ‘Hodarchaeales’!! Syntrophic microaerotolerant peptide-degrading anaerobic archaea w/ simple cell structure & protrusions. Features conserved across the phylum provide new insight into our ancestor’s biology! www.biorxiv.org/content/10.1...
Eukaryotes' closest relatives are internally simple syntrophic archaea
Eukaryotes are theorized to have originated from an archaeal phylum Promethearchaeota (formerly 'Asgard' archaea)1,2. The first cultured representatives revealed valuable insight3,4 but are distantly ...

Underground happy hour? Excited to share our discovery of a new symbiosis between subsurface bacteria and archaea bridged by syntrophic transfer of the smallest alcohol—methanol! @nature.com Work led by a former student Huang Yan, congratulations! rdcu.be/d7W2s
Methanol transfer supports metabolic syntrophy between bacteria and archaea
Nature - Zhaonella formicivorans produces methanol, for a novel syntrophic interaction, without requiring methylated compounds as an input.
