🚨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. #ProtistsOnSky #SciComm #SciSky www.cell.com/cell/fulltex...

This week we were sampling #coccolithophores #protistsonsky on a beautiful Adriatic coast, again. #CoccoChannel Here presenting miss Helicosphaera 🌊🦠🧫🔬

New in @science.org: Calcifying plankton #coccolithophores, #foraminifera & #pteropods quietly drive the ocean carbon pump. Their traits (incl. “shallow dissolution”) are missing from many climate models. Time to put CaCO₃ back in the picture. #ClimateScience 🌊 doi.org/10.1126/scie... #protistsonsky

Congrats @laurentformery.bsky.social Often people ask why we chose to work on a certain problems and a simple answer for us in this case - it’s beautiful. If you want to learn the magic of building crystalline « gems » inside the body - see our latest paper at www.biorxiv.org/content/10.1...

They’re smaller than dust, but crucial for Earth’s climate www.sciencedaily.com/releases/202...

Massive undertaking with @teppo-h.bsky.social and others out. We studied 4 years (!!!) of synthetic 23 microbial species community evolution with/without antibiotic. Resistance mutations occurring over years led to stepwise restructuring and ultimately recovery of undisturbed community composition.

🌍💙 Happy International Coccolithophore Day! 💙🌍 Today, Oct 10, we celebrate tiny ocean builders that capture CO₂, shape marine ecosystems & keep our climate in balance. When Cocco talks, climate walks. #CoccolithophoreDay #OceanClimate #InvisibleHeroes #OceanGuardians #ClimateWarriors #protistsonsky

Microscopic, yet seen from space. Invisible, yet astronauts watch them glow. Billions of tiny artists shape climate, feed the seas, and write history in calcium armor. Meet them in 2 days. #InvisibleHeroes #OceanGuardians #ClimateWarriors #protistsonsky Illustrations: Rosie Sheward

They are architects of the sea, engineers of the air—capturing carbon, atom by atom. While you breathe, they build. While you sleep, they safeguard our climate. #InvisibleHeroes #OceanGuardians #ClimateWarriors #protistsonsky Illustrations by Rosie Sheward

metaPR2 version 3.0 has just been released. Here are the major changes: - Metabarcodes (ASVs) are now annotated with the latest version of the PR2 reference sequence database (5.1.0). - 8 new published datasets have been added from the Arctic and from the South West Pacific. app.metapr2.org
