Connecting tubes between bacteria and a kind of microbe called archaea may reflect a symbiotic relationship that led to complex cells more than 2 billion years ago
Weird microbial partnership shows how complex life may have evolved

So excited to finally show the world a project years in the making. A huge group effort with lots of expertise leading to a unique #Asgard syntrophy story. Very fortunate to have been involved in cultivating and analysing this wonderful organism ❤️

An Asgard archaeon from a modern analog of ancient microbial mats
It has been proposed that eukaryotic cells evolved via symbiosis between sulfate-reducing bacteria and hydrogen-producing archaea. Here we describe a highly enriched culture of a novel Asgard archaeon...

Archaea and Shark Bay featured in the South Australian Museum. Very on theme after my week at ASM!
Single-celled organisms called archaea aren't generally thought to cause human disease, but one species has been implicated in colorectal cancer

Many fantastic talks from AIMI students and researchers at the annual ASM @aussocmic.bsky.social meeting in Adelaide over the past few days. Congrats to all! Dr. Gustavo Espinosa Vergara Lachlan Chisholm Jonathan Koong @hannjbrown.bsky.social
Feeling very honored to be in possession of @snobsi.bsky.social’s lucky microscopy bracelet today as I work my way through 30+ slides on three different microscopes 🙃🔬
Feeling very humbled by receiving this award and equally excited to attend ASM in Adelaide this year! 🎉
ASM NSW-ACT Branch@asm-nswact.bsky.social · last yr.🎉 Congratulations to the winners of the 2025 Early Career Microbiologist Award! 🏆 Winner: Dr Hannah Brown @hannjbrown.bsky.social 🏆 Runner-Up: Dr Binod Rayamajhee We’re proud to support the next generation of microbiology leaders and can’t wait to see where their research takes them!

Excited to announce the Molecular Biology of Archaea (MBoA) 2026! Join us in Cambridge, UK, from 6–10 July 2026 for the only international meeting dedicated to Archaea.
Why would you use a tube rack to transport your plasmid preps around the lab when you can just carry them yourself?
New research on ancient Asgard archaeal ESCRT-III proteins reveals evolutionary secrets of membrane remodelling. Diorge Souza, Javier Espadas and Sami Chaaban, investigated the ESCRT-III proteins with Buzz Baum and Aurelien Roux. Read more: www2.mrc-lmb.cam.ac.uk/asgard-archa... #LMBResearch (1/2)

wuhuu and it's out! Check out our latest Preprint on Bacteria using archaella for swimming! So much fun figuring it out and great collab with @mariejoest.bsky.social @loumollat.bsky.social Najwa Taib and @sgribaldo.bsky.social
Sonja-Verena Albers@archaellum.bsky.social · 2y agoWould you expect that Bacteria use an archaellum for swimming? We didn't, but we found that some Chloroflexota do! Find the story here: www.biorxiv.org/content/10.1... A little thread below 1/n

Never "MinD" bacteria, lets talk #archaea! 🦠 Check out this foundational research from our JAMS treasurer @hannjbrown.bsky.social! 🔬👩🔬 #archaeasky #microsky #womeninstem
Hannah Brown 🧂🦠🔬@hannjbrown.bsky.social · 2y ago🚨 New paper alert! 🚨 MinD is famously known for positioning FtsZ at mid-cell in bacteria In our study, myself and @iduggin.bsky.social found that MinD homologues in Haloferax volcanii influence the localisation of CetZ1, a homologue of FtsZ and tubulin #Archaeasky #Microsky
ARC says they’ll release the Discovery Projects 2025 outcomes tomorrow. Recently, outcomes announcements have tended to happen at/around 11am Canberra time. My bot will pick up the announcement in RMS’s database and post immediately. Good luck!
