$Two Nanochloropsis gaditana cells visualized by quick-freeze deep-etch electron microscopy. Left cell displays a chloroplast containing thylakoids, a nucleus, a mitochondrion, and a fracture face of the plasma membrane. In the right cell, the innermost membrane, marked with pits, is the fractured outer membrane of the chloroplast envelope, above which is the fractured outer membrane of the chloroplast ER, above which is the granular cell wall.$

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.

I use cannibalistic super giant ciliates in my class as an example of, "guess how weird protist diversity can be". AWESOME that this is being explored!

Congratuations Nuria!!!! An anxiety that we mid-career, i.e. old-adjacent, researchers have is whether the best and brightest of our field will find ways to securely stay and carry on the work. Mild, compared to that of the ECRs of course, but what a joy when a deserving young star gets security.

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.

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.

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.
