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

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

The amoeba Difflugia bacillifera builds its shell from things that contain silica, and it is not particular about the source. These ones have incorporated whole shells from another testate amoeba (Euglypha), along with diatoms, algal cysts and chunks of rock. #Amoebae #ProtistsOnSky #peatlands

Super cool!! Every protist needs ExM! 🤩
Congratulations to everyone involved
🚨Our collaboration with @centriolelab.bsky.social & @gautamdey.bsky.social is out today in @cp-cell.bsky.social
We show that #Expansion #Microscopy is a broad-spectrum modality for Euks, enabling 3D phenotypic maps rooted to phylogeny.

✨X-ray crystallography reveals surprising twist in how proteins enter the unique photosynthetic organelles of Paulinella. The chromatophore targeting peptide (crTP) folds into a 3D structure, hinting that folded proteins cross peptidoglycan and inner membrane. (1/2)

A new preprint from us using a single-cell genome pipeline to investigate diversity of uncultured Bodo spp. flagellates.

We isolated 7 Bodo spp. cells from a single environmental sample and show that they represent 3 Bodo sp. each with a unique species of bacterial endosymbiont. #protistsonsky

A large fraction of aquatic bacteria remains uncultured. Here, the authors cultivated 627 strains of abundant freshwater bacteria from 14 European lakes, thus generating a collection that includes many previously uncultured, oligotrophic bacteria that may serve as model organisms.

I've seen this several times: when Acantharians get big enough they like to eat tintinnids. And they always orient with the lorica opening pointed in: like they are slurping up a little jello shot. That glass house can't protect you from these weird predators little ciliate! 🦑 #protistsonsky
