This is the professional account for the Evolutionary Cell Biology lab of Prof. Joel Dacks.
My first bluesky post of 2026. I was away in the UK, for meetings with colleagues but also got to sneak in a few visits with more friends, old and new alike. In what has been a turbulent and disquieting year across the world already, personal connections and support are more important than ever.

What a great way to end the year! This work, with a superb team, gave us the chance to put out some ideas about the evolution of meiosis (and other organellar systems) during eukaryogenesis. Congratulations especially to our undergrad Lisa Matsuo on her first ever paper:)
@cloeucl.bsky.social
Matsuo, @dackslabecb.bsky.social et al. perform comparative genomics and phylogenetic analyses of eukaryote paralogous DNA recombinases Rad51 and meiosis-specific DMC1, showing they resolve separately from any archaeal RadA sequences.

Wow! Super exciting science:)
Just on time for the holidays! Happy to share the published version of the discovery of leptophytes, a new deep-branching and widespread group of microalgae based on plastid MAGs (ptMAGs). Now with additional support from a mitochondrial MAG (mtMAG) of leptophytes.

The first candle of Channukah; the lights on a Christmas tree; the solstice as the time when the days get brighter; they are about finding a light in the darkest of times.
Intentionally looking for, and appreciating something positive, when things seem dire can be a powerful act.
Now and always.

This is fucking grim. Somebody invented a white guy, an "IT professional" named Edward Crabtree, who stopped the Bondi shooting and spread it all over the internet, which was picked up by AI agents and slop aggregation sites.

The real hero is a fruit stand owner named Ahmed el Ahmed.

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

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.

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

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.
Editor-in-Chief Joel Dacks looks back on the year and shares some of our new initiatives, including "Issue Highlight" image and AI use guidance.
