Haven't posted here in a bit. But the public school teachers' strike is over, my program grant is submitted, and our household is now COVID-free. Heard a great seminar today, had a catch up with a long-time collaborator, and taught a grad class to a very talented set of students. Happy Friday!

We are looking for a PhD student to work on an exciting plastid endosymbiosis in microbial eukaryotes. This position involves sampling, exciting microscopy such as CARDFISH, ExM and FIBSEM, single-cell transcriptomics and more. #protistsonsky 1/2

Our paper on the #genome of the Trebouxia #photobiont from Xanthoria is now out in @newphyt.bsky.social! Check below for a near-chromosome level assembly, secretome analysis, evidence of ancient HGT, and transcriptomic comparison of the alga in symbiosis and in pure culture doi.org/10.1111/nph.70728

Holy smokes!!!!

Exciting day for the lab: our 1rst paper is officially out in @currentbiology.bsky.social 🥳 Wonderful collaboration wt @gautamdey.bsky.social showing how Cryo-ExM achieves consistent immunostaining in diverse diatoms, from the lab and the natural environment 1/n #ProtistsOnSky tinyurl.com/2zxaund7

Excited to share our new paper! Tepsin and AP4 mediate transport from the trans-Golgi to the plant-like vacuole in Toxoplasma gondii. A great collaboration between the Meissner, Jiménez-Ruiz, and Dacks labs 🙌 #Toxoplasma #Apicomplexa #Golgi #CellBiology #Parasites

Always happy to be involved in work that better explains how parasite cells function. Especially in a group like apicomplexans with such a global health impact (Malaria, Theileria, Cryptosporidium). The more we know, the better people are able to find ways to combat them. doi.org/10.1083/jcb....

OK sure, it started out as a typo, but I d like the idea measuring of a gene or protein's "Conswervation". Just feels more groovy and less judgemental than 'divergence".

What you're looking at is a brand new protist species! 🤯🔬 Isn't it beautiful? This image is just a glimpse of what's to come. We can't wait to share our full findings soon, in partnership with Guifré @beaplab.bsky.social @luisjagago.bsky.social. Stay tuned! #NewSpecies #protistsonSky #diversity

One is the best EMBO/EMBL symposium is coming up and it’s going to be AWESOME. Save the date !

New #ISEPpapers! Towards a trait-based framework for protist ecology and evolution: Mahwash Jamy et al. www.cell.com/trends/micro... #protists #algae #microbes #ecology #evolution

I reflect on the changes in the past year and introduce and explain the rationale for JEM's newly established AI guidelines. Most importantly, this piece discusses what I see as the core mission of the journal: to provide a venue for the voices of Protistologists. Hope you like it.

The first paper from my PhD is out now! doi.org/10.1111/jeu.... We describe a new photosynthetic #Paulinella species from a brackish beach in British Columbia 🇨🇦 Big thanks to the co-authors Maia Palka and @alive-in-the-ocean.bsky.social, and my supervisor @fburki.bsky.social #protistsonsky

Check out our recent publication on breviate protists and their microbial communities. In this study, led by PhD student Karla and postdoc Julie, we found that breviate growth under anoxia might be dependent on the metabolic capabilities of the prokaryotes they live with. doi.org/10.1093/isme...

Moving fast and stressing hard about getting things done before vacation (and being grumpy about it). Then I opened my laptop to the news of the passing of a mentor and colleague. Her memory will be a blessing and guide. Good reminder about priorities today, though. Connections over check-lists.

Really interesting work!!

We have a postdoc opening for a protistologist with biophysics inclinations to join our @hfspo.bsky.social project! (focus will be on characterising the morphology, ultrastructure and behaviour of excavates) #protistsonsky Apply by Sept 17th (RTs appreciated!) jobs.exeter.ac.uk/hrpr_webrecr...

Drafting a budget for an upcoming grant and asked a colleague how much lab space I'd need to culture the fungi I plan to study. They said as mushroom as possible. ...I regret nothing.

🌟 New paper out! 🌟 Multi-omics reveals the microbial consortium sustaining Monocercomonoides exilis in vitro 🧬 Huge thanks to everyone involved, especially my project supervisor, Vladimír Hampl! 🙌 Read 👉 doi.org/10.1186/s407... #Microbiology #Protists #MicrobialEcology #Multiomics #OpenAccess

I love the image of the eukaryotic tree!

Wanna read about ARFGAPs, protists, Asgards, and the evolution of the endomembrane system? Have I got a paper for you! This was a pleasure to work on with two great collaborators, Cathy Jackson (@ijmonod.bsky.social) and Anna Novák Vanclová. onlinelibrary.wiley.com/doi/10.1111/...

Congratulations Monica!!

Exciting news: our Board of Trustees has appointed @monicabettencourt.bsky.social as the CRG's new Director. Prof Bettencourt-Dias is expected to take up the post in 2026, replacing Dr. Luis Serrano, who will continue to maintain a research group at the institute. www.crg.eu/en/news/moni...

Please Re-Post. Our global GRUMP microbial ocean database is out in Scientific Data! Unfractionated, single universal PCR, with Archaea, Bacteria, and Eukaryotes all on the same scale with the same denominator. Pole to pole, depths to 6000m. Lots of metadata. www.nature.com/articles/s41...

Thanks ICOP/ISOP2025! I had a blast. See you in Prague! #protistsonsky

Congratulations! Great to see this work already making an impact. We've included it in the recent JEM Special Collection on Parasitology too! onlinelibrary.wiley.com/doi/toc/10.1...

Such a pleasure to accept the Department of Medicine Basic Science Publication Award for 2025, for our paper, "https://www.pnas.org/doi/10.1073/pnas.2403601121", on behalf of all co-authors.

Though taxonomy, species description, or evolution might (rightly) spring to mind when you think of JEM, we also publish tons of super parasitology papers! Here are a few of the greatest hits from the past 5 years. If you've got a protist parasite manuscript to go out, consider JEM😀

Excited to share our new paper in @cellreports.bsky.social that reshapes our understanding of chromosome organization's deep evolutionary roots! Our work dives into the origins of the machinery that structures our very genomes. 🔗: doi.org/10.1016/j.ce... #Genomics #Evolution #CellBiology #LECA

Oh sure, because my 'cool papers to read when I get a chance' pile wasn't big enough. Thanks a lot! ...No seriously, thank you. This looks excellent. @deemteam.bsky.social @lauraeme.bsky.social @andrewjroger.bsky.social

I am so looking forward to reading this!

This is the paper with the highlighted image for the new issue of JEM, now that we've changed from a different cover image every time. Congratulations to the authors!

Attention Protistology Hive MInd: Looking for suggestions for the best/most complete/not divergent Rhizarian genome to search. B. natans is missing something and we'd like to double check if this is a real loss or just false negative.

Thrilled to announce this work on an under-appreciated molecular complex in marine algae! Congratulations to all co-authors: past, visiting, and long past (Richard😜) *Longer thread on the big picture impact of 'Jotnarlogs' for cell biology forth-coming* #protistsonsky www.cell.com/iscience/ful...

Beautiful!
