๐Ÿงช NSF GRFP update! New graduate NSF fellowships will likely be announced this week for the GRFP (see bottom of ๐Ÿงต for why). First off, I'm *very* glad to hear of those going forward, given the otherwise bleak year so far for graduate training. Some observations... 1/12

Asgard Archaea May Hold the Key to the Origins of Eukaryoticย Life A group of single-celled organisms known as Asgard archaea has drawn scientific attention for its potential link to the evolution of complex life. These microbes were first identified through gene fragments in deep-sea sediments.โ€ฆ

The #UConn Microbial Ecophysiology Lab congratulates MSc. Isis Del Mazo-Monsalvo on her publication! MSc. Isis is an expert in metabolism & enzymes, and she is now using these skills to investigate the biology of #methane-producing microbes (#methanogens) in the human gut.

Rahhhโ€ฆ archaea are so cool!

Ten years ago, nobody knew that Asgard archaea even existed. In 2015, however, researchers examining deep-sea sediments discovered gene fragments that indicated a new and previously undiscovered form of microbes.

Asgard archaea have actin - but what about microtubules? Where do they come from? ๐Ÿง Our new paper www.cell.com/cell/fulltex... by @xujwet.bsky.social & @florianwollweber.bsky.social, in collaboration with the Schleper & Wieczorek labs, describes tiny Asgard microtubules! #TeamTomo #ArchaeaSky 1/6

Fantastic paper! Excited to dive into the details, and great to see some U-ExM on Asgard archaea! Huge congrats to the entire team! ๐Ÿ‘๐ŸŽ‰"

Asgard archaea are full of surprises, this time we found (tiny) microtubules (snapshots of microtubule evolution?!) - Check out our new paper on the cytoskeleton of Lokiarchaeum ossiferum: www.cell.com/cell/fulltex...
