So happy to announce our new preprint, “A geothermal amoeba sets a new upper temperature limit for eukaryotes.” We cultured a novel amoeba from Lassen Volcanic NP (CA, USA) that divides at 63°C (145°F) 🔥 - a new record for euk growth!

Is it a flagellate? A tiny ball with tentacles? Contamination in my ciliate culture? NEW SUPERGROUP OF EUKARYOTES? Yes to all 4! Meet Solarion - just out in #Nature doi.org/10.1038/s415... Huge congrats to Marek Valt, Cepicka Lab & the star team! Very happy to be part of this project. #ProtistsOnSky

How do cells adapt morphology to function? In a 🔥 preprint by @zjmaggiexu.bsky.social , with @dudinlab.bsky.social and @amyweeks.bsky.social , we identify a self-organizing single-cell morphology circuit that optimizes the feeding trap structure of the suctorian P. collini. 🧵 tinyurl.com/4k8nv926

Adenine DNA methylation associated with transcriptionally permissive chromatin is widespread across eukaryotes - Nature Genetics Long-read sequencing in 18 unicellular eukaryotes reveals that 6mA is widespread across eukaryotes and is enriched at transcriptionally permissive regions, which are also marked by H3K4me3.

Out today, our take on 6-methyladenine #6mA evolution in Eukaryotes @natgenet.nature.com. We asked a simple question, is really DNA 6mA common across the eukaryotes? The answer is "yes" if you're a unicellular eukaryote 🦠, not so if you're multicellular 🐝🌱🍄. www.nature.com/articles/s41... 1/9

Wow! Congrats @fmikus.bsky.social @gautamdey.bsky.social @dudinlab.bsky.social and all authors! Superb resource!

🚨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.

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

Why do some planktonic protists develop a gelatinous matrix? We suggest that this original adaptation is a strategy to cope with ocean oligotrophy: doi.org/10.1111/1462...
