Our paper is out! Analysis of 30K+ genomes revealed that CPR bacteria assemble their ribosomes in unconventional ways, and that these assembly processes appear to have co-evolved with ribosome structure. doi.org/10.1093/molb... #Ribosome #Evolution #Patescibacteria #MBE

Thermophiles don’t just survive heat, they thrive in it. 🔥

They provide heat-stable enzymes, insights into early Earth, and tools for biotech.

Our new thematic issue in #FEMSMicrobiolEcol captures how diverse this field is. Explore the collection👉 buff.ly/kD8fmOL

Our latest paper has just been published in Cell!

doi.org/10.1016/j.ce...

We developed a new method called MCC ultra, which allows 3D chromatin structure to be visualised with a 1 base pair pixel size.

Lab’s first paper is out!! We show the first structures of #Asgard #chromatin by #cryo-EM 🧬❄️
Asgard histones form closed and open hypernucleosomes. Closed are conserved across #Archaea, while open resemble eukaryotic H3–H4 octasomes and are Asgard-specific. More here: www.cell.com/molecular-ce...
