We tested the efficacy of semi-permeable capsules to capture protists from cultures and environmental samples using the Onyx from @atrandi.bsky.social. Tremendous effort from everyone in the lab and led by Marco Fantini and Nik Brask - check out the videos here: www.biorxiv.org/content/10.6...

Just was reading today in Cavalier-Smith's autobiography (DOI 10.5281/zenodo.18733366) on his studies of nucleomorphs, and that it is still unclear what was the red algal donor. He would be glad to read this, I am sure!

Can anyone help to identify the genome? 😄

Ever wanted to see how a coral skeleton grows? In this paper (led by: @jtrendbio.bsky.social) www.sciencedirect.com/science/arti... we use Live CT, a method of scanning live organisms using microCT, to visualise how the skeleton grew over about one month.

whoa. stunning siphonophore by @schmidtocean.bsky.social ! youtube.com/shorts/G218j...

Meet Hexatilemonas jangsaensis a new uncultured apusomonad clade by Jeong et al. doi 10.1111/1462-2920.70282. #protistsonsky. Mark the trunk 🐘 (sleeve around base of flagellum) and laterally consumed bacterium in 🟥 .

and you know what to do #protistsonsky

Hello epithelia enthusiasts! I’m @inesfournon.bsky.social and I study epithelial mechanics in sea anemones 🪼 Did you know epithelial cell extrusion had never been described outside bilaterian animals before? Well… not anymore 👀 Read ⬇️🧵1/9

Expansion microscopy of a loricate choanoflagellate, generated by Mylan Ansel in our lab 🤩 (yes, the lorica expands. No, we don't understand how either)

Madness. A bacterium with a 10kb genome, lost replication initiation, translation.., relies on symbiotic host. www.nature.com/articles/s41...

Every day is a good day for sharing one of the most useful papers about research data ever written. PLEASE get your people to understand and follow this advice. www.tandfonline.com/doi/full/10....

Living patescibacterial (CPR) cells are a rare sight! Meet Strigamonas methylophilicida, a parasite of methylotrophic proteobacteria we just described in our latest paper: doi.org/10.1128/mbio...

Finally, how can we discover microbial symbioses in the ocean? A single-cell omics approach in combination with machine learning can automate the discovery process www.biorxiv.org/content/bior... #EESSymbiosis

Last talk for the day, @floravincent.bsky.social on diatomes' symbioses. How can we study them in natural environments? Expansion microscopy together with immunolabeling can give a high-resolution picture. See more here www.cell.com/current-biol... #EESSymbiosis

I was looking for new materials to add to my nematode lecture and stumbling up some highly explicit worm porn, starring a pair of Caenorhabditis elegans. 🧪 From here: www.wormatlas.org/male/musclei...

My new spiritual eukaryote is ciliate in Si helmet swimming towards North pole ⚔️. Definitely an amazing reading from Bolzoni et al. "Magnetoreception in a freshwater ciliate arises from endosymbiosis." 10.1038/s41467-026-70462-8 for #protistsonsky

In a study led by @choannaflagellate.bsky.social and @evocellbio.bsky.social using samples from a local mudflat in Maine, we found evidence of a new lineage of #protistsonsky that helps fill in gaps in our understanding of breviate (+Obozoa) mitochondrial evolution. www.bigelow.org/news/article...

My friends in the Life of Retaria group decided to make a podcast! In the first episode, they interview @fabnot.bsky.social about his journey as a scientist. I loved the first episode, hope you do too! @juliemeilland.bsky.social @sandinmm.bsky.social et al. thelifeofretaria.github.io/podcast.html

A new mechanism for “RNA memory”! This time in Planaria! (Here's a video of a Planarian with mulitple heads, one of the heritable phenotypes we studied). This work summarizes >10 years of research and is an amazing collaboration with the labs of Jochen Rink and Omri Wurtzel labs. Read thrad below👇

I see that footage all over the BSky, I am also amazed, reposting gladly. Would be really interesting to have more than "Foram" lable (can it be not foram? 🫢). Which of 4Kish extant forams? Globigerinid? Can we narrow further with size? We are #protistsonsky! Lets do some expert work if we can 🙂

I look at these kinds of protists ALL THE TIME. I have never seen them in situ like this. One cell. Absolutely remarkable. #protistsonsky

sounds fun!

Great to see this paper in all its glory online: link.springer.com/article/10.1... A huge effort from Gordon and the team at @pjkeelinglab.bsky.social! Phylogenomic tree of Cercozoa based on single-cell transcriptomes from 100 uncultured cells @ubcbotany.bsky.social @science.ubc.ca

Salinity tunes mode of multicellularity in a tidepool choanoflagellate www.nature.com/articles/s41... - paper in @nature.com

Excited to share our new preprint exploring how Paramecium achieves diverse flow functions, i.e. feeding and swimming, simultaneously. This work was spearheaded by our ExM expert, PhD student Daphne Laan @daphnelaan.bsky.social : www.biorxiv.org/content/10.6...

I am happy to share the unfinished but nevertheless fascinating autobiography of the late Thomas Cavalier-Smith, written in 2020, shortly before Tom passed away in 2021. I thank Ema Cavalier-Smith for sharing the text with me. I recently finished curating […] [Original post on biologists.social]

One of the biggest questions in biology is how complex cells evolved about 2 billion years ago. Here's my new story on how scientists are solving the mystery of eukaryotes like us. Gift link: nyti.ms/4qMbo22

Not something you see in textbooks very often: tripolar mitosis.

🗣️Protist friends! I'm looking to put together a list of key protistology resources for new students joining the lab. What are some of your favourite papers??? 🧪 #protistsonsky

We are happy to share our newest preprint on a novel strain of Ca. Lokiarchaeum ossiferum, that contains an active provirus, capable of excision and independent replication! We propose a novel virus family: Fylgjaviridae. www.biorxiv.org/content/10.6...

Our latest preprint: Together with the team of Jan Löwe, @danieltamarit.bsky.social and many others we discovered and characterized several Asgard tubulin genes and propose that microtubule architecture and dynamics evolved in Asgard archaea prior to eukaryogenesis www.biorxiv.org/content/10.6...

I don't know, but very curious what his might be. The pseudopodia on one end only, suggest some shell, probably organic and poorly visible...

A great resource from Maia and friends! onlinelibrary.wiley.com/doi/10.1111/...

Check out our latest pre-print of our favourite pets - the breviates. This work was led by Zhezhen Yi in collaboration with @andrewjroger.bsky.social and many others! By studying diverse breviates we were able to see how different metabolic pathways can evolved in response to low-oxygen.

Proud and excited to share our work with the community! Helen @helenfoster.bsky.social Foster et al. study how #cilia axonemes are built. 👀 Don't miss the gorgeous and insightful movies by @margotriggi.bsky.social, they really show our discoveries in full action! www.biorxiv.org/content/10.6...

wow! Check out these floating nuclei!

New paper out! Here's a puzzle: phototrophy, the ability to use light for energy, is one of life's great innovations. It evolved early and transformed the biosphere. But it evolved 2x. Why not just once, why not more? Our work suggests the answer is priority effects. www.nature.com/articles/s44...
