We are recruiting a PhD student to tackle a fundamental question in cancer biology: how DNA replication fails at centromeres and drives chromosomal instability (CIN) — a major driver of tumour evolution and therapy resistance.

Born #OnThisDay in 1922, Esther Lederberg was the first to isolate the lambda phage in 1951. She characterised the lysogenic phase, whereby the phage are able to integrate into the bacterial genome, staying dormant. This discovery made them a model tool of study, leading to many more breakthroughs.

New preprint from the lab !!! 🥳
In this work, we explore the 3D genome architecture of the virulent phage PAK_P3 during its infection cycle in P. Aeruginosa. We unveil a highly dynamic structuration as well as specific interactions patterns.

Are you a long-time fan of Archaea, an extremophile-phile, or are you simply curious?

Either way, we have good news.
We’re delighted to announce the 2026 EMBO Workshop on Archaea, 6–10 July.

Sign up: meetings.embo.org/event/26-arc...

We look forward to seeing you in Cambridge, UK

Bacterial genomes encode a rich repertoire of antiphage systems, but we still know surprisingly little about when these systems are actually expressed.

In this preprint, Lucas Paoli et al, ask what shapes antiphage systems expression in native contexts.

Environment and physiology shape antiphage system expression
Bacteria and archaea encode on average ten antiphage systems. Quorum sensing, cellular, or transcription factors can regulate specific systems (CRISPR-Cas, CBASS). Yet, a systematic assessment of anti...

DNA topoisomerases are essential enzymes found in all cells, where they regulate DNA supercoiling. Reverse gyrase (RG) is a unique type of topoisomerase that introduces positive supercoils into DNA an...

gene names are great but really making sure a unique ID (genbank or consort) is mentioned somewhere in a paper is essential, future us will be thankful

Chromosome segregation in the highly polyploid archeon Haloferax volcanii was long thought to be random. Turns out a ParA family protein coupled with a non parB protein does the job. Is that one of the few examples of active segregaton of multi copy identical replicons?

1/10 Genome maintenance by telomerase is a fundamental process in nearly all eukaryotes. But where does it come from?

Today, we report the discovery of telomerase homologs in a family of antiviral RTs, revealing an unexpected evolutionary origin in bacteria.
