Yes, managed to roll in the station and get out with my kids before the flames really picked.. Thanks to a Shell lady who doused it quickly in extinguisher, there was no explosion, even if we filled the place with smoke and panic 😅

When it's so hot that your car catches fire on the road and you almost explode a gas station🔥🔥🔥

This paper combines two sort-of-crazy (in the best sense) approaches in cryoEM sample preparation:
(1) Native, soft-landing electrospray ion beam deposition, followed by (2) deposition of amorphous ice, and reheating and freezing by laser flash melting. Has potential for time-resolved studies.

Two weeks left to apply!!!

NEW: Judge Burroughs GRANTS Harvard's requested TRO against the Trump administration, blocking it from revoking Harvard's ability to enroll international students during early court proceedings.

In-cell discovery and characterization of a non-canonical bacterial protein translocation-folding complex Cryo-electron tomography has emerged as powerful technology for in-cell structural biology, and in combination with breakthroughs in protein structure prediction, offers a unique opportunity for illum...

This is just an excellent preprint by Rasmus Jensen and colleagues from Julia Mahamid's lab @embl.org - a tour de force of Cryogenic electron tomography to do in cell structural biology in which they discover a new complex and solve its structure and function! www.biorxiv.org/content/10.1...

Someone posted this and I have been back to the original on repeat since 😄.. Captures perfectly the current mood, Imma losin' m'self in the sciencccccce 🤓🤓🤓🤓

Fellow ladies in science, as part of the disappearing species of international female scientists in France and perhaps every/elsewhere, I want to bring your special attention to our institute's open call for group leaders 👩‍🔬🦠🧪🔬🤓!!! Come join me in doing some coolicious science here 🙏!

Deciphering the formation of cooperative multicellular biofilms Bacterial films are a hazard throughout the healthcare system, and as antibiotic resistance increases there is an even greater imperative...

🦠 Most #bacteria form #biofilms, protective communities that resist #antibiotics.

Petya Krasteva's research explores the structure & behaviour of these biofilms, hoping to develop new #antimicrobial strategies.

Molecular Distinction of Cell Wall and Capsular Polysaccharides in Encapsulated Pathogens by In Situ Magic-Angle Spinning NMR Techniques Pathogenic fungal and bacterial cells are enveloped within a cell wall, a molecular barrier at their cell surface, and a critical architecture that constantly evolves during pathogenesis. Understandin...

Hahahh, not even, nothing is linear there and there's even a double bond for fun 🤣🤣🤣

I am not a chemist and must be brain-dead after prolonged ogling of electron density clouds but how TF is this cellopentaose 🤔?

And another one bites the flux 🤘🤘🤘! Molecular replacement was tricky mostly because of Alphafold lacking imagination 😅! Beautiful home source data at 1.9 Å courtesy again of Xtal master @bkauffmann.bsky.social at our @iecb.bsky.social

Has been a while since we bothered to set up crystal trays, cryo-EM got us so spoiled 😄.. Not bad data either, home source dataset at 1.7 Å courtesy of our Xtal guru @bkauffmann.bsky.social at our @iecb.bsky.social 🤓🙏💠..

Welcome to Bluesky and thank you for this post 🙏. Indeed it was a real rollercoaster and this grant came as a lifeboat in the cold and lifeless ocean of public research in France, where institutional support is a net negative 😄. So we'll rock on for another 5 years while ignoring admin emails 🤘🤘🤘

Happy to share our 📖 chapter on bacterial cellulose secretion! It took too long in press so it doesn't include our latest work on pEtN-cellulose secretion (doi.org/10.1038/s414...), which settled many open questions but nevertheless, hope you enjoy the read 🤓!

Can you add me to the pack 🙏

The mofo also got the Regeneron antibody cocktail, as well as the fun steroid treatment before either were widely available..

Changing the future of medicine: How Brown is becoming a global hub for RNA research The ambitious goal of the new Brown RNA Center is to untangle the mysteries of human RNA, which could be instrumental in preventing and developing treatments for a wide variety of complex diseases.

@djuranoviclab.bsky.social will be Djuranovic lab at Brown University and newly formed RNA Center from July 1st 2025.
Postdoc as well as staff scientist positions will be available.

Really nice (again 🤓!) but why it took so long to have it peer-reviewed? Have to read it in detail to see how it was improved scientifically, but I just hope it wasn't more of a ping-pong exercise for the reviewers 🙃...

Now out in NSMB for those who missed our biorxiv back in 2023.. bacterial ESCRT-III-like #Vipp1 forms dynamic spiral filaments on membrane! Spirals are springs that drive 3D ring formation in the spiral centre! 😵‍💫 wonderful collaboration with Adai Colom’s lab and @rouxlab.bsky.social
