Hello #microsky! Now that I've made it here, let me introduce myself:
3rd yr PhD uncovering the world of archaeal tubulins 🧬
🦠-iologist by training but dabbling in proteins thanks to @kmichie.bsky.social
Also your friendly neighbourhood @jamsorgsyd.bsky.social secretary ✍️

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.

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.

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."

🚨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. 🧪🪐

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

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. 👩🔬🔬👩💻

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...
