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 🧪🧶🧬🔬🌾

Looks like I am late to this party but have exciting news. I’ve been awarded an ERC Starting Grant to study #XtrmCells! Thankful to @erc.europa.eus for this opportunity, and to my collaborators, mentors, and group for their support. Looking forward to exploring the mechanics of these cells!

Wasn't expecting this from @theguardian given their usual reports. Have a look, and maybe realise the problem is maybe not solely confined to "the right wing government" but slighlty more systematic than that. youtu.be/nMyyVaiY4V8?...

The final version of our multispectral microscopy manuscript is now online at Nature Photonics: www.nature.com/articles/s41... The main additions are some further comparisons to yet more unmixing algorithms, in which we find that our algorithm is still the most accurate.

Be our new colleague! 🎉 The Dept of Molecular and Cellular Biology at the University of Geneva is hiring an Assistant Professor or Associate Professor. 👉 More details here: lnkd.in/e8Z9eAm4 👉 Our department: mocel.unige.ch Please feel free to share this opportunity with your network.

Go for the choanos, leave with a duck ! Congrats @thibautbrunet.bsky.social & @maitefreired.bsky.social

Super Happy for you Can & the Team !

Wirshing, Lew et al. @mit.edu address how mothers partition growth equally among their buds in the multi-budding yeast Aureobasidium pullulans. Equal partitioning stems directly from effective equalization of #polarity sites. rupress.org/jcb/article/... #Cytoskeleton #Development

A lovely video profiling the efforts of scientists like @dudinlab.bsky.social to explore a set of amazing animal relatives and what they may teach us about the evolution of multicellular life (I know its from SpringerNature via Meta but they do a very good job) 🧪 www.facebook.com/share/v/1B9i...

A new #UExM probe for #Actin! Fun times thinking/developing/testing with @centriolelab.bsky.social & @lreymond.bsky.social ! Congrats to all ! If interested in #UExM, or #HAK-Actin, feel free to reach out ! Soon available at @spirochrome.com #Expansion #Microscopy #ProtistsOnSky

A nice piece about how exploring various species at the root of animals is getting us closer to partially understand how #animals may have evolved. Happy to have contributed a tiny part. PS: Im convinced that #microbial #eukaryotes, who are mainly #unicellular, still rule the earth #ProtistsOnSky

+1 here. Reach us out early enough ! Getting funding and personal timelines aligned rarely happens over night !

BIG NEWS!! We will be hiring a new professor with 25 years of endowed funding at the @biozentrum.unibas.ch @unibas.ch, focused on using biophysics and structural biology to explore climate-related fundamental science topics. Come start an innovative research cluster with us! 🧪🔬🧶🧬🌾🌍

What could be more exciting than watching Euplotes scurry around under the microscope? How about adding some raptorial predation by supergiant cannibal cells? www.biorxiv.org/content/10.1... Video by Vittorio Boscaro. 1/n

Congrats to the whole team. It was quite fun to teach @kristina-prokina.bsky.social how to #UExM If i'm not mistaken, this would be the first intance of new species discription using some #UExM. I know it won't be the last !

I gave a symposium talk at the European Society for Evolutionary Biology 2025 (#eseb2025) meeting last week and this was my title slide showcasing how I was speaking as an independent scientist because @dalhousieu.bsky.social @dalhousie.bsky.social has locked us out.

Want to help us image and understand those incredible samples Felix just collected at UBC - and many more? 2 more days to apply! embl.wd103.myworkdayjobs.com/en-US/EMBL/j... #ExM #PlanetaryCellBiology 🧪🧬🔬🌍🌱🦠

The list of successfully fixed species keeps getting longer and longer. Can’t wait for the first #UExM images fresh out of our new scopes… Amazing job @fmikus.bsky.social and thanks @pjkeelinglab.bsky.social, @fburki.bsky.social, Denis, Vittorio and all for joining forces !

Israeli military’s own data indicates civilian death rate of 83% in Gaza war | Gaza | The Guardian share.google/NefplVsVz4ir... Getting close to the top 3 that no one ever wished for. Also... not "death rate", "killing rate" is more appropriate...

If you received an email pretending I need some Google or Apple Pay cards ... I don't, and it's not me. Just make sure the exact email address and realize I don't live in Poland !

Here are some bonus (remarkable) UExM images of Oophila algae from my lab cultures (not directly related to the study) @dudinlab.bsky.social: your protocol (www.protocols.io/view/u-exm-o...) worked pretty well the first go!

After nearly twenty years in the making, our attempt at understanding what makes the chaetognath phylum so unique has finally been published! www.nature.com/articles/s41... with #LauraPiovani @dariagavr.bsky.social @alexdemendoza.bsky.social @chemamd.bsky.social and others /1

Check out our recent publication on breviate protists and their microbial communities. In this study, led by PhD student Karla and postdoc Julie, we found that breviate growth under anoxia might be dependent on the metabolic capabilities of the prokaryotes they live with. doi.org/10.1093/isme...

Happy to have our #UExM students for the next two weeks! Rachid & Sneha coming directly from NYU #AbuDhabi& Andrea from Innsbruck University More #Microbial #Eukaryotes! also some Fish tissues! JOIN US with @gautamdey.bsky.social @fmikus.bsky.social on this @moorefound.bsky.social funded adventure.

Maybe it's time we rethink the idea that development is a cell centric process? In this beautiful review, María-del-Carmen and @stramerlab.bsky.social discussed how the ECM underlies and influences many morphogenesis processes from wing unfolding to mammary gland development. doi.org/10.1016/j.cd...

Grateful to the folks @CurrentBiology.bsky.social for the fun Q&A! Come for the beetles, stay for the symbionts — and forgive the basketball detour 🪲🦠🏀 www.cell.com/current-biol...

Join our crazy beautiful project of ExM Atlas ! One more position to fill, this time for a Research Technician at @embl.org in @gautamdey.bsky.social lab. Come have fun with us !.

1/n Fun journey continues: Our new @cp-cellstemcell.bsky.social paper out on how the Inherent & Dormant Plasticity of Mouse Naive PSCs can be "Exaggerated" to Directly form ~E8.5 Transgene-Free (TF) Mouse SEMs & WITHOUT inducing 8-16-Morula-like "Embryo Founder Cells". www.cell.com/cell-stem-ce...

This saga keeps on giving ! Congrats to the whole team.

Our first #Hydra paper. @anaisbailles.bsky.social all the way, with crucial theory contributions from Carl Modes and @zechnerlab.bsky.social Hydra maintenance by Heino Andreas and HCR by Giulia Serafini. Teamwork. Many thanks to the generous Hydra research community.

Many of you feel hopeless and #powerless - so take a moment to understand & learn more. You are all invited to learn something new about #Palestine through #culture thid week ? Not only these are good #documentaries / #movies... they are our #reality.

Such a pleasure to be co-organising the #Latsis Symposium this year with Guillermina ! Thanks to all the speakers & sponsors. And all our teams members who helped make this a reality. It just felt right. #Science #WildCells #ProtistsOnSky #Cell #Biology #Biophysics #Behaviour

Come and Join our Dpt in Beautiful #Geneva ! We are looking for a #Microscopy & #Image #Analysis expert to help all of us at the Dpt.

How do cells switch on the actin assembly at endocytic sites? How can this on-switch evolve? Check out our new preprint! www.biorxiv.org/content/10.1...

To understand well, The R'equip, which is the previous equipment call is cancelled & to replace it, we are now allowed to ask for equipment funds within Project grant calls? But must remain within the 1M/grant which was already there? Is this novelty or blatant budget cuts? Am I getting it right?

This is just so beautiful. Congrats y'all..

When the #breakfast joint knows you too well ? #Korea
