Hard to think the EMBO/EMBL symposium on the cellular mechanics of #symbiosis is already over @embl.org. Some personal scientific heroes in there, and a very unique collegial and open minded vibe (and great dancers💃🏻 ) #EESSymbiosis Wonderful way to reconnect with science after 🐣! #womeninscience

Welcome to Day 1 of #EESSymbiosis! ✨ 🔬🧫 From host cells to insects and marine unicellular eukaryotes, today’s discussions showcased innovative methods in symbiosis research. We’re excited to take you along on this journey as we explore the fascinating complexities of symbiotic function.

As emerging models gain traction during this uncertain funding landscape, the need for sustainable and scalable approaches is pressing. Our effort to implement accessible genetics in choanoflagellates and share our strategy is now out. We hope the community finds this helpful and invite feedback.

Are you curious about animal origins? Want to perturb their genetics to find out more? Now it's a lot cheaper: the FUNR @frutag33.bsky.social Lab's effort to make transfection more accessible for choanos (& relatives) is up now! 🧬

Microflora Danica: What can you learn from collecting and sequencing 10,000+ samples from a single country? Check out our new paper in @nature.com to find out. Incredible work led by Caitlin Singleton, Thomas B. N. Jensen, and Mads Albertsen from @aau.dk. 🦠🧫🧬 www.nature.com/articles/s41...

seems that protists were way ahead of us with the invention of the circular economy 😊 great to hear of 'holobionts' again 👍 #SymnioSky #MicroSky #ProtistsOnSky

Protist–bacteria partnerships are more common in wastewater treatment plants than we thought. In this ISME communications paper, we uncovered widespread denitrifying endosymbionts inside ciliates, their global distribution, and their temporal dynamics across WWTPs.🦠 academic.oup.com/ismecommun/a...

🧪 Submit your abstract for #EESSymbiosis and get the chance to present your research, receive qualified feedback and help develop our understanding of the complexities of symbiotic function. You have until 25 Nov: https://s.embl.org/ees26-03-bl 🗓️ 17 – 20 Mar 2026 📍 EMBL Heidelberg and Virtual

This work shines because of @zjmaggiexu.bsky.social passion for these cells. She built it all—the cultures, transcriptomes, analyses, modeling and collaborations—from scratch. I can’t begin to express how brilliant and hard-working a scientist she is (and she's 👀 for postdocs!). So proud of her 🥲

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

Wow! Remarkably complete story on the logic of phenotypic plasticity in a predatory protist - congrats @cellraiser.bsky.social et al!
