Promethearchaeota Persistence in Marine Sediments Frozen for Over 100 kyr

Archaeal lineages of Promethearchaeota phylum were found to survive in marine sediments frozen for over 100 kyr. These findings not only enhance our understanding of evolutionary processes under long...

Mental health advocacy from @snobsi.bsky.social @jamsorgsyd.bsky.social So inspiring and such an important thing to know. De-stigmatise.

The murder map, regarding freezer stocks... A cautionary tale from @snobsi.bsky.social @jamsorgsyd.bsky.social

Biggest thank you to TJ for coming along! What I love about JAMS is how I've gotten to know people like you outside my immediate university network!

Stef, I'm so fkn proud of you. Its been a joy seeing your PhD journey. And kudos on the honest talk @jamsorgsyd.bsky.social @snobsi.bsky.social

🧫 JAMS Sydney is back! 🧫 We’re kicking off 2026 with an Archaea Special 🔬 📅 24 February ⏰ 6–8 pm 📍 Shakespeare Hotel, 200 Devonshire St, Surry Hills New year, new venue, and a deep dive into one of the most fascinating domains of life. #JAMSSydney

Hint: I am one of the speaker details that are coming soon. So save the date for some fun Archaea talk and behind-the-scenes insights from me, a recently submitted PhD. 🦠👩‍🔬🦠

wow... crawling motility in Asgard #archaea!! www.biorxiv.org/content/10.1... look at these crazy moves!! Let's face it, what these cells want for Christmas is #cilia... the best type of motility appendage...

Dynamic protrusions mediate unique crawling motility in Asgard Archaea (Promethearchaeota)

Crawling motility is a hallmark of eukaryotic cells and requires a dynamic actin cytoskeleton, regulated adhesion, and spatially organized signalling pathways1–3. Asgard archaea (phylum Promethearchae...

To write well you first have to write badly. Get some words down. However bad you think they are, you now have something to improve on. Review, rewrite and repeat. #acwri #PhDchat #PhDforum #ECRchat

Clone-FISH paper out: Manuscript/resource alert #microsky 🦠 We present a collection of 30 E. coli (CloneFISH) cultures, each carrying a plasmid for the heterologous expression of a (near) full-length 16S rRNA gene from one of 30 lineages of archaea, including 17 yet uncultured ones.

Breaking up the thesis writing by engaging in some #citizenscience for the Sydney Sea Slugs Census 🤿🐌🪸📸 This was the spot of the day from Wylie's Baths - identified as a Plocamorpherus imperialis on iNaturalist. #nudibranchs #underwaterphotography #sydneyseaslugcensus

Here, we show that deep below, corals and feather stars don’t just share space – they share microbes. Endozoicomonadaceae + Nitrosopumilaceae inhabit both hosts in a “promiscuous” symbiosis that may fuel nitrogen cycling in the deep sea. doi.org/10.1186/s401... 🌊🪸🧪 #Bioinformatics 🧬💻 #SymbioSky

Following NASA's recent announcement of a potential biosignature on Mars, I want to replug my colleague @fletcher42.bsky.social's work on exogeoconservation! As they state - "There is a need to balance the greatest scientific returns with limiting the impact of taking samples." 🧪🔭👩‍🚀

Steffi J Nobs@snobsi.bsky.social · 2y ago

🚨New #astrobiology Paper Alert🚨 Great work by my colleague Clare Fletcher on publishing another chapter of their thesis which, in a nutshell, aims to stop _certain people_ from putting flags on Mars and trampling the planet. 🧪🪐 doi.org/10.1016/j.ps...

Back with another post about how I stay grounded whilst writing up my thesis! This morning's sunrise was insane 🌄

PhD exit seminar ✅ So happy I could share the bulk of my PhD where I optimised the expression, purification and (so far unsuccessful) polymerisation of novel eukaryotic-like proteins in Nelly (aka Loki-ASV2).

Listening to Stephanie Nobbs (@snobsi.bsky.social) telling us about the fascinating Asgard archaea isolated from Shark Bay's microbial mats. They isolated a new archaea and assembled its genome and in silico proteome. Found lots of eukaryote-like tubulins + new protein folds @unswbabs.bsky.social

New review out in Annual Review of Marine Science! 🌊🧫 We explore how ammonia-oxidising microbes form symbioses with marine hosts - fueling the nitrogen cycle, fixing carbon, and possibly feeding their hosts. #Metagenomics 🧪 #Bioinformatics 🧬💻 #SymbioSky 🔗 doi.org/10.1146/annu...

Thank you to the #archaea community for making my first #GRC a great one! I'm grateful to have had the opportunity to present and meet lovely new people! ❤️🦠 Coming from an island country, it was also great to put faces (and personalities) to names I otherwise only see on papers. 👩‍🔬🔬👩‍💻

#GRS and #GRC #Archaea in the Swiss Alps: great meetings and location! Many familiar and even more new faces. Going home with exciting ideas and collaboration initiatives on exploring #archaeal #viruses in #soil! Thanks to everyone 😉

How do I celebrate my first preprint coming out in the middle of the GRC? A swim in an Alpine like followed by a glass of Prosecco. 🥂

🚨 FIRST PAPER ALERT 🚨 My first research paper I've been involved with is out now as a preprint 🦠🥳🦠 #archaea #microsky #PhD

Xabier Vázquez-Campos@xabivc.bsky.social · last yr.

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 #archaeasky #archaea www.biorxiv.org/content/10.1...

Half-way through my first GRC and I've; 🦠 Presented a well-received talk 🦠 Walked on a glacier 🦠 Not once had to explain what Asgard Archaea are

Bonjour La Suisse Romande 🇨🇭One day between FEMS2025 and GRS: Archaea! What did I do? Visit the Montreux Jazz Festival of course 🎺 🎶 🎷

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

The final day of #FEMS2025 is done! Great opening session on extremophiles, an interesting discussion of using microbes as forensic tools and I've left with plenty of microbe nerds to bother the next time I'm in Europe 🦠🤓 Ciao Milano!

Day 2 of #FEMS2025 done! Loved meeting other microbe nerds and listening to some great talks. Im 100% biased today's session on extremophiles has been my favourite so far 🦠 🥶 🥵🧂 🦠

Loved my first full day at #FEMS2025 🦠 Thank you to everyone who came to chat with me at my poster. Can't wait to see more great speakers and talk more microbes tomorrow 👩‍🔬

Bongiorno Milano! Made it to #FEMS2025 after exploring the city. Catch me tomorrow (Tuesday) at poster 241.15P, Section D to talk Asgard archaea, protein folding and microbial dark matter. 🦠🔬 🦠
