The sediment in these cores is pungent. ‘Smells like a new phylum’ says Stavros. We are all hoping for a new old one.

An outcrop 200m down. Beggiatoa - bacterial threads like rice noodles. That means sulphur. We take a sample with a vacuum.

Up on the bridge of Falkor (too), Lucia is surveying the horizon for marine mammals. So far on the trip she has spotted a playful group of humpbacks, dolphins, sperm whales and a southern right whale.

2470m down - tracking the bottom. The sediment is flat with large spirals drawn by worms in the mud. Anyone thinking Escrt-III?

Waiting for the wind to subside, while the ship maps a channel on the sea floor for the next dive, Galen visits the bridge and settles right in.

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...

And just when you thought things were settling down, the enigmatic Asgard archaea have another surprise in store! Cell cycle/life cycle stage-specific internal compartments with almost no eukaryote-derived clues as to how they might function.
Beautiful tomography and microscopy - congrats all 🤩
