Weird microbial partnership shows how complex life may have evolved 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

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...

Our new preprint with a new #Asgard from stromatolites (and its Desulfobacterota companion). Complete circularised genomes of both, cool #cryoem images, protein modelling, etc

Big group effort with a lot of people involved

🚨 FIRST PAPER ALERT 🚨

My first research paper I've been involved with is out now as a preprint 🦠🥳🦠

Archaea and Shark Bay featured in the South Australian Museum. Very on theme after my week at ASM!

Weird 'harmless' microbes may play a pivotal role in colorectal cancer Single-celled organisms called archaea aren't generally thought to cause human disease, but one species has been implicated in colorectal cancer

Still no, but this recent paper is a pretty cool one!

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!

Thrilled to be at #ASM2025 @aussocmic.bsky.social this year and excited to explore Adelaide!

Have the best time Stef! Don’t do your ACL again 😅

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! 🎉

What a missed opportunity... 🤔 We should have declared an official "Archaeal Week" at Nature Communications! 😆

Great review on the diversity of archaeal S-layers! 🧫

Brand new preprint on #AMR plasmids in Acinetobacter from @mehrad-hamidian.bsky.social
@liamtobin1.bsky.social and @margaretlam.bsky.social

Congratulations all 👏🏻👏🏻👏🏻

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?

Evolution, structure and membrane remodelling function of the ESCRT-III superfamily in eukaryotes and their closest relatives Asgard archaea. The two subfamilies, B-type and A-type, have distinct structural properties to perform sequential steps of the membrane remodelling pathway.

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.

Check out the new episode of Archaeacast!

@archaealex.bsky.social and I discuss the intricacies of Thermophiles, followed with a fantastic interview by Theopi Rados with Dr. Rachel Whitaker.

Join us in beautiful York, UK!

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

This is amazing! I need one for six well plates! Would have saved me MANY hours during my PhD.

Unraveling the Mysteries of Sleep: Exploring Phylogenomic Sleep Signals in the Recently Characterized Archaeal Phylum Lokiarchaeota near Loki’s Castle Sleep is a universally conserved behavior with an elusive origin and an uncertain evolutionary purpose. Leveraging phylogenomics, we investigate the evolutionary foundations of sleep by identifying or...

🚨 bogus paper alert 🚨
Guess what's wrong with this preprint!?

Level: easy

But at least it gave me a good chuckle 🤭
