📝New preprint! #MicroSky 🕰️We chart the full, synchronized lifecycle of a predatory bacterium using Hi-C, RNA-seq, ChIP-seq & microscopy. 🧬We uncover dramatic shifts in nucleoid architecture & transcription, tightly coordinated with predation. www.biorxiv.org/content/10.1...

New PrePrint from the Vecchiarelli and Mosalaganti (@shyamalm.bsky.social) labs! 🧵 Collaboration with the Giessen and Pi labs Congratulations to co-first authors Y Hoang (@hoanghamyy.bsky.social) and Pankaj Jadhav! www.biorxiv.org/content/10.1...

Some (+)ve news to lighten another heavy weekend: our latest preprint (c/o Mattiroli + Ramani labs) is up! www.biorxiv.org/content/10.1... A tour-de-force by 1st authors Bruna Eckhardt & @palindromephd.bsky.social, focusing on chromatin replication. RTs welcome; tweetorial in 3,2...(1/n)

Really enjoying reading this primer on single particle tracking #microscopy by @svanteeffelen.bsky.social and colleagues www.nature.com/articles/s43... (pdf on Sven's website)

New paper out! We show that RecBC remodels single-stranded DNA gaps to protect them from ExoI (sbcB) 3′-5′ exonuclease degradation during replication of damaged DNA. doi.org/10.1073/pnas...

Excited to share another study from my lab @fordhamchem now out @narjournal.bsky.social‬: doi.org/10.1093/nar/.... Most bacterial DNA polymerases must interact with the sliding clamp DnaN for their function, but we show that it’s more complicated in B. subtilis DNA replication. (1/4)

Less than two weeks left to apply! Postdoc positions in my lab to study 1. initiation of DNA replication. 2. chromatin replication/epigenetic inheritance. Great for biochemists, biophysicists & structural biologists. Deadline 3 August 2025. crick.wd3.myworkdayjobs.com/External/job...

It is finally out 👍😀. Great job of the team (mostly absent from Bsky) and @m-saponaro.bsky.social CDK-driven phosphorylation of TRAIP is essential for mitotic replisome disassembly and MiDAS url: academic.oup.com/nar/article/...

Great opportunity for an established scientist to move and grow their research group in beautiful Montreal! The Canada Excellence Research Chair (CERC) in Climate Change, Environment and Health at @mcgill.ca Apply by Aug. 8. Please share widely! mcgill.wd3.myworkdayjobs.com/en-US/McGill...

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/...

A must-read for histone afficionados: our new review on 'Histone-mediated chromatin organization in prokaryotes and viruses' www.cell.com/trends/bioch... @samuelschwab.bsky.social @vikramalva.bsky.social

I'm very excited that my first postdoc paper is out now at @nature.com! www.nature.com/articles/s41... I developed new single cell CDK sensors to investigate how CDK orchestrates mitosis including investigating bistability/hysteresis, how activity is propagated, and the role of centrosomes.

CdpA-an archaeal anchor for FtsZ! Excited to be part of this. (FtsZ is easily my favourite protein and the whole larger family in Archaea are intriguing). www.nature.com/articles/s41...

Check out this tour de force by Nils Meiresonne and colleagues, establishing FLIM-FRET as a reliable way to study protein interactions in live bacteria with spatiotemporal resolution! We open the door to exploring divisome protein interactions during cell division. www.biorxiv.org/content/10.1...

Our new paper on FtsN is out! Now there are three tracks for organized cell wall constriction-- the old, boring E. coli always manages to surprise us. A special shout-out to all the people who made this work possible, especially Dr. Jason Lyu, and Dr. David Weiss. www.nature.com/articles/s41...

Our new study of chromatin ubiquitylation by variant PRC1 on the single-molecule scale: We visualize directly how vPRC1 ubiquitylates neighboring nucleosomes during a single binding event, showing a potential mechanism how H2Aub domains are established. www.science.org/doi/10.1126/...

New paper! Most human DNA replication initiation is dispersed throughout the genome with only a minority within previously identified initiation zones genomebiology.biomedcentral.com/articles/10.... Identifying human DNA replication initiation sites on single molecules by @nanoporetech.com 1/7

I got hit by some rather sudden and extreme financial hardship so if anyone is in need of remote wetlab contract research, strictly BSL1, do let me know. Currently scrambling for gigs. Plant, Bacterial, Archaeal Non-model Bioeng Custom Lab Hardware Turn Key Genetic Design Please repost for reach 💚

Biofilm architecture determines the dissemination of conjugative plasmids: We measured the spatiotemporal spread of plasmids in biofilms and found that plasmids only spread in some biofilm regions! Collab with lab of @sbigot.bsky.social & Christian Lesterlin www.pnas.org/doi/10.1073/...

Our set of new prokaryote-optimized fluorescent proteins is now published ! #microbiology #microsky #microscopy 🧫🦠🔬 www.science.org/doi/10.1126/...

And its out! Last work of the lab: "Evolutionary Constraints on RNA Polymerase Gene Positioning in the Genome of Fast-Growing Bacteria." We show how the genomic location of RNA polymerase impacts cell physiology. www.biorxiv.org/cgi/content/...

We are looking for a postdoc with microbiology background for #superresolution #singlemolecule #ERC tracking project. Apply by 27.4.2025. 🦠🔬🧫 Pls share! www.aalto.fi/en/open-posi...

Interested in the bacterial ParABS DNA segregation system? Then have a look at our latest preprint... 🧬 Thanks to the Hennig and Bange groups for the great collaboration! doi.org/10.1101/2025...

Glad to share the work of @yli18smc.bsky.social and co on Lamassu, a bacterial defense system related to Rad50/Mre11 (RM). While RM carefully trims DNA ends for repair, Lamassu chops up the host chromosome. Our study reveals how it is regulated to minimize damage, activating only during infection.

Excited to share my first postdoc paper - a tool to engineer mtDNA deletions in human cells and study their pathogenic impact ✂️🧬🧫

Ever wonder what happens when a bacterial replisome encounters a wee nick in the chromosome? Then check out this study by @winterhalterlab.bsky.social What about a vertebrate replisome? Check out the work of @jamesmdewar.bsky.social www.biorxiv.org/content/10.1... www.biorxiv.org/content/10.1...

Happy to share the beautiful structure of a Wadjet SMC complex by @roisnehamelinf.bsky.social, with support from the DCI and @drhonsworth.bsky.social ! This is a type II Wadjet with unique characteristics including a tandem KITE subunit, distinct coiled coil architecture and a deviant hinge.

Our new preprint is out＠bioRxiv: www.biorxiv.org/content/10.1... @masaashimazoe.bsky.social et al. reveal that linker histone H1 acts as a liquid-like glue to organize chromatin in living cells. 🎉 Fantastic collab with @rcollepardo.bsky.social @janhuemar.bsky.social and others—huge thanks! 🙌 1/

How do replisomes walk on DNA? And what happens when they run into a G-quadruplex? @sahilbatra.bsky.social and @benallwein.bsky.social provide unexpected insight in our latest paper with Richard Hite @mskcancercenter.bsky.social @science.org www.science.org/doi/10.1126/.... Congrats to all authors!

We are looking for a postdoc in #EvolutionarySystemsBiology. Exciting science, amazing team, wonderful city! landrylab.ibis.ulaval.ca/research-opp... #evolution #synbio #systemsbiology #genomics

we are recruiting a postdoc to work on a collaborative project with the lab of Nynke Dekker in Oxford @nynkedekkerlab.bsky.social. Please RT www.hubrecht.eu/job/postdoc-...

If you're interested in chromosome biology (DNA folding, gene regulation, replication, polymer modelling and more) we're organising the below this autumn. It'd be great to see you there. Please share if you can. :-)

Only a few days left to apply!

Fascinating paper! No G2/M checkpoint for under-replicated cells! academic.oup.com/nar/article/...
