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...

As you should >:-)

The colors are so good 😍

Ok ok ok last one 😂 here's my 1987 time trial bianchi!!! Also super light, and also rides like a dream. Ive had it for 16 years now 🥹

steel really DO be real ;-) here's my very beloved vintage MTB frame that I turned into a gravel bike! The older ones are cooler <3

I organized a writing retreat for the Keeling Lab at the Hakai Institute for this weekend. Gonna be hanging out in this yurt for the next two days 😀📝📖📃📚

Yall are making me jealous!!!!!

Hope you find some rads ;-)

Agreed

yes 😊 they are single celled organisms that are often very beautiful and complex, like this one!

And some parting #protist shots - two giant acantharians hand-collected with prey inside (a copepod and maybe a foram) - crazy to see a copepod being digested by an acanth, so curious how the acanth managed to catch it! #microbialsky #microsky #christmasatsea ❤️🌊

New preprint out! Using ~75k environmental OTUs + 77 fossil calibrations, we reconstructed a Proterozoic timeline of eukaryote evolution. Our results show crown eukaryotes were already diversifying >1.6 Ga, long before the first undisputed fossils (~1.05 Ga).

Happy to share this work with Virginia Sanchez-Puerta (not on bsky) and colleagues on how loss of photosynthesis in these (strange!) plants affects translation and tRNAs in plastids and mitochondria....

I've been knitting on my bus rides to work enough in the last year that I finished a sweater with fish on it 🐟 still waiting for the knitters that sell knitting patterns to develop protist colorwork sweater patterns...

Very nice, Yash!

Our 2nd heterotrophic #Paulinella culture!
Really proud of this one. After days at the microscope picking cells, I finally got it growing happily :)

Made some cyanotype prints from a figure I pulled from @sandinmm.bsky.social 's 2019 paper on the morpho-molecular classification of Nassellaria. #protistsonsky

Those SEMs are so stunning, they were just begging to be turned into art!

Was literally just panicking about this over the weekend 💩

I love the way they move

😂 maybe four stuck together

It was identified as a nectosome elsewhere 😌

Anybody know what this marine invert is? It's from an epipelagic plankton net tow in the middle of the Atlantic #invertID
