Excited to share our new findings in @science.org on how the DRT3 bacterial defense system uses a reverse transcriptase that builds DNA repeats without a nucleic acid template. Microbes never cease to amaze!

This one means a lot. Our paper, “Large extrachromosomal replicons are widespread across bacterial lineages and show coordinated replication termination and spatial coupling with the chromosome,” is out!

How diverse is bacterial immunity ?
We report in @science.org how language models allowed us to predict 2.4M antiphage proteins spanning >23K novel potential systems.

Bacterial genomes often include extrachromosomal replicons, ranging from small plasmids to chromosome-scale replicons. Here, Czarnecki et al. analyse more than 40,000 complete bacterial genomes and sh...
Excited to share our discovery of a new programmable RNA-guided DNA-targeting system hiding inside bacteriophages that predates CRISPR.
We call it VIPR (Viral Interference Programmable Repeat), and it uses an entirely new logic to find its targets.
Thread + link below.
"The selfish ribosome" paper is now published in @plosbiology.org . Have a look! Many thanks to the editors and reviewers!

Our ms on re-sampling 4 years apart vibrio phage in natural environments is now out with some improvements. First, clearer evidence of cryptic population dynamics between phage and vibrio, presumably because of genetic diversity. www.nature.com/articles/s41...
It remains unclear how viral genomes remain relatively stable over time, given the rapid co-evolution seen within hosts. Here, authors explore complex marine phage-bacteria dynamics using over 1000 ph...
New preprint alert!!! 🚀🤓 We are very happy to finally share this with the world — the result of seven years of work and a new tool to study integrons and discover new functions encoded in these bacterial platforms.

In this Essay, the evolution of life is construed as a ribosomal takeover, whereby the ribosome evolved to consume most of the cell’s resources, while other cellular componentry ensured the propagatio...
npj Biofilms and Microbiomes - Targeted elimination of Staphylococcus aureus mastitis infections with synthetic phage-based CRISPR-Cas delivery systems
With Eugene Koonin, we propose a concept of “the selfish ribosome”, under which evolution of life is viewed as a ribosomal takeover, where the ribosome evolved to consume most of the cell’s resources, while other cellular componentry ensures the propagation of the ribosome. arxiv.org/abs/2602.23268
