📢#TMHMS25 is just around the corner! 🦠🌊
Join us to dive into the latest discoveries in #marinehostmicrobesymbioses and explore how microbial superpowers can contribute to restoring ocean health!
Please share with fellow marine science and microbiology enthusiasts!
@mingpapilio.bsky.social shaking up evolutionary theory at #eseb2025
Models linking species diversity with ecological stability may not be as straightforward as we thought! Amazing talk
Congrats! Such a neat system
Check out our new preprint all about Pirsonia, a tiny killer of bloom-forming Coscinodiscus diatoms!

Custom made microscope setup to live image samples from a 96 well plate
Spent the week in Cambridge with @benkinsjenkins.bsky.social testing this custom made microscope to live image Aiptasia larvae. Got some cool videos that we hope to share very soon! Thanks for hosting me Ben!
Very exciting!
Had a great time messing with microscopes and sea anemones with @micro-megs.bsky.social this week

🪸🌊 Hidden coral cities!
Scientists just found ancient “super reefs” in the Maldives’ twilight zone, thriving reefs that may help restore shallow corals threatened by climate change.

📢 Deadline extended to May 5!
Join our #ESEB2025 symposium on symbioses in microbial eukaryotes - from the origin of organelles to their roles in ecosystem functioning. Share your work and meet our great speakers @cstairs.bsky.social & @benkinsjenkins.bsky.social
#ESEB25 #Symbiosis #ProtistOnSky
First study from the lab is out! We describe ApuRs, a new family of microbial rhodopsins unique from apusomonads. ApuRs represent the first anion-conducting rhodopsin channels that can be controlled by UV light, offering potential as new optogenetic tools. #protistsonsky

This is very cool! Do you reckon reduced cell-cycle control has any influence on bleaching tolerance when Durusdinium is present?
Cell cycle arrest in the cnidarian-dinoflagellate symbiosis.
Corals maintain stable populations of essential photosynthetic symbionts by controlling their cell cycle, not by eating them! Our new #PNAS paper monitored and modelled #aiptasia cell cycle, autophagy, and expulsion for over a year. #symbiosis #microbiology www.pnas.org/doi/10.1073/...
I am obviously biased, but this should be a great conference (as long as you don't mind hearing me go on about Paramecium and corals) ! 🦠🪸
I've been busy the last couple years developing Aiptasia as a genetically tractable model organism to study corals. Here you can see me injecting CRISPR-Cas9 into these fragile little Aiptasia zygotes. Hopefully soon we will have our very first mutant lines!
Absolutely phenomenal week for the #EESWildModels.
A pure celebration of biological wonders, and incredibly engaged participants.
Thanks to all the co-organizers and @events.embl.org for making this possible !
See you in 2027 ? (please fill the feedback form)
Very excited for this first of its kind EMBO/EMBL Symposium on the Wild Frontiers of Model Organisms.
So far Session 1 is a blast, from aiptasia symbiosis, oyster vibrio phage interactions, !!

I had a wild time presenting my coral work for the first time at EMBO/EMBL #EESWildModels.
Massive thanks to @embl.org @events.embl.org and the organisers for putting this together. It was a real pleasure to interact with so many weird and wonderful creatures...
...and their model organisms (!!)
Very excited and proud to finally share this story! 🐙
We discovered surprising roles for dopamine and acetylcholine in the Octopus visual system…

I'm pleased to introduce our new paper rooting the eukaryote Tree of Life (eToL) that resulted from a collaboration led by PhD student Kelsey Williamson and a large group of collaborators doi.org/10.1038/s415...htt
🚨 New paper alert! 🚨
A robustly rooted tree of eukaryotes sheds light on their deep evolutionary ancestry—suggesting that the Last Eukaryotic Common Ancestor (LECA) may have had an excavate-like cell architecture. 🧵🔬 (1/) www.nature.com/articles/s41...
Thanks! The work is great and I had a lot of fun writing this
If you haven't already, read the fantastic original publication by Jacko-Reynolds @ambonacolta.bsky.social @fonamental.bsky.social @pjkeelinglab.bsky.social and the gang

These parasite-like partners have lost photosynthesis but retained chlorophyll... are they friend or foe?

In our new paper we discuss how modern coexistence theory can help microbial ecologists tackle fundamental & applied questions, and how microbial systems can help to push coexistence theory forward! With Andrew Letten and Dave Armitage (@darmitage.bsky.social). doi.org/10.1111/1462...

Is it this one? Congrats everyone #protistsonsky

Paper came out today that represents a long trip for many members of my lab. It took years to get these methods to work and gather the data so everyone involved should be very proud of the interesting outcome. Thanks to the whole gang for their perseverance on this one!
Have you used #network_analyses in the past to analyse your #ecology data? Have you wondered how many of those correlations actually represent interactions between #microorganisms? Here I present a paper how we leveraged #protistsonsky to evaluate the validity of the method. A thread:
