Excited to see our new work published! We have established the evolutionary and ecological context of our favorite model Caulobacter and made some unexpected findings. Who would have thought that close relatives lack dimorphism? And have potential for phototrophy? www.nature.com/articles/s41...

indeed, 𝘙𝘶𝘨𝘰𝘴𝘪𝘵𝘢𝘭𝘦𝘢 𝘰𝘳𝘺𝘻𝘢𝘦 looke like fusilli, which are notably better at holding on salsa di pomodoro than spaghetti... and as pasta addicts, we fell instantly in love with the shape of this newly described alphaproteo from the Rhizobiales 🤭 #MicroSky

The bacterial #SOSresponse unfolds in a defined temporal order, but how does this arise? @adityakamat.bsky.social @anjbadri.bsky.social &co show that intrinsic #promoter strength, modulated by #SigmaFactor usage, governs timing of SOS gene activation in Caulobacter @plosbiology.org 🧪 plos.io/4oAKf0Q

1/Now published! We identify a novel regulatory layer underlying SOS response dynamic. Find a short summary about our findings below. journals.plos.org/plosbiology/... #MicroSky

Now published. Thank you very much to our collaborative team, and very supportive editors and reviewers!!! www.pnas.org/doi/10.1073/...

Assembly, architecture and functional roles of microbial surface layers Review article published in @natrevmicro.nature.com with @bupbuse.bsky.social, Andriko von Kügelgen and @vikramalva.bsky.social. S-layers are everywhere! www.nature.com/articles/s41...

Thrilled to share our multidisiplinary work on how genome-wide DNA bridging by H-NS reshapes the stationary phase bacterial nucleoid and affects the transcriptional landscape. With Xindan Wang and @meyerroc.bsky.social www.biorxiv.org/content/10.1...

new preprint from our group & Antoine Hocher: www.biorxiv.org/content/10.1... A fantastic collaboration with Antoine, with Jovana Kaljevic' initiated the collaboration and drives the project.

Independent research fellowships leading to tenured positions at the John Innes Centre. Repost = nice. Thank you very much!!!

🚨🚨🚨Calling all Caulophiles and Alpha aficionados - stayed tuned for a virtual CauloCon in early 2026. And HOPEFULLY an in person alpha meeting in 2027!! DM me or @chienlab.bsky.social w questions or to stay in the know.

🚨New paper out! #MicroSky Studying obligate predators like Bdellovibrio bacteriovorus is tricky—essential genes for predation are also essential for survival. We expanded its genetic toolbox: 🧬promoters to fine-tune expression 🧬IPTG-inducible system 🧬CRISPRi for rapid knockdown bit.ly/46GUn2c 1/4

N6-methyladenine modification of DNA enhances RecA-mediated homologous recombination www.pnas.org/doi/10.1073/...

🚨 Imagine a bacterium that refuses to follow the textbook: It grows as tangled filaments, divides unevenly, reshapes its own membranes… and even builds grappling hooks. Meet Litorilinea aerophila — and here’s why it blew our minds.

Biophysics enthusiasts, do consider applying for the seventh session of YBM! Submit your abstracts by 20th August.

#MicroSky Summer read! Predatory bacteria kill and eat other bacteria. Their deadly actions come in many flavors, often via direct physical contact between predator & prey 🧛 How do they do it? Our review 📖 @coralietesseur.bsky.social @ysantin.bsky.social www.sciencedirect.com/science/arti...

And the story is published now!🍾 www.nature.com/articles/s41... Open access link: rdcu.be/exnOc Many years in the making, great collaboration with @archaellum.bsky.social & @tunglejic.bsky.social Thanks @ukri.org BBSRC & @leverhulme.ac.uk for funding, reviewers & editor!! 🙏 #microsky #archaeasky

Theoretical physics enthusiasts, do consider submitting an abstract for the upcoming sixth YBM! Submit your abstracts here: t.co/W1qGraRpAc

In @elife.bsky.social: Bacteriophage infection drives loss of β-lactam resistance in methicillin-resistant Staphylococcus aureus doi.org/10.7554/eLif...

Happy to see our collaborative work on the contractile injection system (CIS) in Streptomyces published. We show that the membrane protein CisA gives Streptomyces CIS a licence to kill. @pilhoferlab.bsky.social & Bastien Casu, @joesallmen.bsky.social #MicroSky elifesciences.org/articles/104...

The fifth session of YBM is coming up next week. Join us for two exciting talks on Monday (7th July) at 11am (EDT). Mark your calendars🗓️: tinyurl.com/29b7yk47 Meeting link: shorturl.at/0ng5A

Finally published! Many thanks to the reviewers and editor whose comments & suggestions improved this work significantly more than the first preprint version!!! www.pnas.org/doi/10.1073/...

The excitement continues! Check out my latest preprint examining how phages have adapted to lyse different bacterial envelopes. I found a lysis gene (lysZ) that is conserved in phages that infect corynebacteria mycobacteria, and other actinos. www.biorxiv.org/content/10.1...

I'm pleased to announce that I will be starting my lab as an Assistant Professor at UMass Chan Medical School in August! My group will study phages that infect corynebacteria and mycobacteria to understand bacterial cell envelope assembly and phage gene function. Website and more info to come soon!

#PhDone! 🎓 Congratulations Dr Shivangi Verma! 🎊 @shivangiv10.bsky.social from Prof Vatsala Thirumalai's lab successfully defended her thesis! 🧵👇Check out the thread to learn more about her work on understanding how neuronal networks are sculpted in the cerebellum during development 🧠 (1/5)

I’m excited that the work by Diego Ramirez and Lei Yin is out, where they gained several key insights into what provides the force underlying bacterial cell division doi.org/10.1101/2025.... To divide, cells must first bend the membrane inward, a process that’s energetically expensive
