After exploring Europe’s coastlines, EMBL’s TREC expedition is moving inland! 💧 The new Traversing Ecosystems phase focuses on freshwater habitats – studying how human activity and environmental change affect life at the molecular level. www.embl.org/news/science...

Have you ever looked at the night sky and wondered if there’s a chlorophyll f in the reaction centre of Photosystem I from far-red light adapted cyanobacteria? 🦠 Well, we did (don’t judge) and the work that followed is now out as a First Release in @science.org www.science.org/doi/10.1126/...

Pretty excited to share our new preprint! Non-photosynthetic Plastid Replacement by a Primary Plastid in the Making www.biorxiv.org/content/10.1...

Life knows how to keep going - even if it’s freezing -15 degrees C 🥶 outside. AGU just covered our discovery of ultra resistant ice diatoms gliding into a world record! 🧪🔬Enjoy the story here: eos.org/articles/ice...

EXCITING NEWS!! We're searching for a new professor colleague at the Biozentrum🇨🇭.

Time for a thread!🧵 How different is the molecular organization of thylakoids in “higher” plants🌱? To find out, we teamed up with @profmattjohnson.bsky.social to dive into spinach chloroplasts with #CryoET ❄️🔬. Curious? ..Read on! #TeamTomo #PlantScience 🧪 🧶🧬 🌾 elifesciences.org/articles/105... 1/🧵

I am excited to share our new preprint on the CAGE complex, a mysterious hollow protein complex that I first saw years ago while surveying Tetrahymena ciliary lysate www.biorxiv.org/content/10.1... #cilia #protistsonsky 🧬🧪

A molecular-resolution look into the near-native architecture of the spinach chloroplast🌱. This one was a long time in the oven, but we're happy to finally share our "version of record". What long-standing debates did we settle? Check back for a short thread🧵 on Monday. #TeamTomo #PlantScience 🧪🧶🧬🔬🌾

🌱 Using ‘compelling’ methods, including #CryoET, researchers mapped spinach thylakoid membranes at single-molecule precision, revealing how photosynthetic complexes are organised and settling long-standing debates on chloroplast architecture. buff.ly/j3TSIkn

We found a new #ecological factor in #microbial mats: the #bacterial contractile injection system. Using #cryoET, #metagenomics, & quantitative #immunoTEM, we studied this feature directly in natural populations of bacterial #cells.

90% of you probably don’t need to read this. But maybe some of you are curious & 10% will feel seen. Or a little less alone. This isn’t about seeking sympathy. It’s about sharing something hard to say out loud; partly to heal, partly in case someone needs to hear it too. (1/3) tinyurl.com/DudinO
