Fer’s tour de force in B. anthracis is out! Fer got Tn-seq running, built an ordered knockout library, defined all essential sporulation genes, and found a peptidoglycan deacetylase inhibitor critical for engulfment. Including our first one-by-all Alphafold screen! journals.plos.org/plosbiology/...

‘Chromosomal Topological Domain Formation Modulates Transcription and the Coupling of Neighboring Genes in Escherichia coli‘ by Drs. Nico Yehya, Christopher Bohrer, and collaborators, is now available on bioRxiv. Check it out! doi: doi.org/10.1101/2025...

Really cool paper from @vincentdebakker.bsky.social @jonbakerlab.bsky.social now published @natcomms.nature.com #MicroSky www.nature.com/articles/s41...

Hmmm This work has so many implications on literature 😳😬 Fluorescein-based dyes are not valid reporters of oxidative stress in bacteria, and conclusions based on their use must be reconsidered | PNAS www.pnas.org/doi/10.1073/...

Happy to share our latest T6SS review: nature.com/articles/s41... Thank you, Jan, Danny (@dannyjamesward.bsky.social), Joana (@joanampereira.bsky.social), as well as reviewers and editors @natrevmicro.nature.com!

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...

Very happy to share that a large part of my thesis work is out today: B. subtilis uses the second messenger c-di-AMP to modulate its turgor pressure in response to the state of its cell envelope. www.nature.com/articles/s41...

time to admit as a REAL bacteriologist

Our latest preprint www.biorxiv.org/content/10.1..., describes Willi Stepp’s project to make smart microscopy even gentler by doing event detection in phase contrast. We developed neural networks to detect mito-LD and mito-lysosome contacts, as well as mitochondrial pre-fission constrictions.

Happy to share Asha Joseph and Inchara Adhikashreni's latest work from the lab, describing replisome speed variation in Caulobacter! www.cell.com/current-biol...

It has been coming a long way... happy to share our latest work with you: www.biorxiv.org/content/10.1... Here, we show the importance of septal fortification by the Class A Penicillin Binding Protein, PBP1b, in E. coli and provide a molecular mechanism for this function. (1/12).

In @molecularmicro.bsky.social: two special issues on Prokaryotic Chromosome Organization. Many excellent contributions, including a vision article: 'Future directions of the Prokaryotic Chromosome Field', outcome of BioPhyChrom 2023 @biophychrom.bsky.social onlinelibrary.wiley.com/doi/10.1111/...

Expansion microscopy (ExM) of the entire mouse body (pubs.acs.org/doi/10.1021/...), developed by the labs of Profs. Jae-Byum Chang and Young-Gyu Yoon (former SynthNeuro postdocs running labs at KAIST), could empower studies of how multiple systems (nervous, immune, etc.) interact across scales.

I'm thrilled to share that our review article, "Molecular Level Super-Resolution Fluorescence Imaging," has now been published online (www.annualreviews.org/content/jour...)! We provide a comprehensive overview of fluorescence super-res methods that push the limits towards molecular-scale imaging.

ÅNGSTRÖM-RESOLUTION IMAGING OF CELL-SURFACE GLYCANS 🧬🎨🍬 The glycocalyx, our cells' sugar coat, holds secrets in immunology, cancer, viral infections, and more. Visualizing its molecular architecture was impossible… until now. #glycotime #microscopy www.biorxiv.org/content/10.1...

SAVE THE DATE ‼️ 📆 📢 BBM 2025 will be held on June 9-10th at the Harvard Science Center feat. the one and only Dr. Petra Levin as keynote! We can't wait to see you there. Registration and scholarship applications open next week.

Awesome data from the Moffit lab! #spatialbiology www.science.org/doi/abs/10.1...

Many people talk about the "Golden Age of Antibiotics", but I hadn't seen it visualized properly. Just how many types of antibiotics were discovered during that time? So, I visualized it myself!
