🔈Paper out! We turned the most fascinating phage host-switch mechanism, diversity-generating retroelements, into a programmable mutagenesis tool, DGRec. You can perform targeted hypermutation of any 50-200bp sequence directly in vivo in E. coli www.nature.com/articles/s41...
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!

Excited to see the major chapter of my PhD in print!
We present a massively-parallel approach for screening CRISPR edits in plants to speed up agricultural test cycles + benchmark genomic LMs.
Thanks to my fantastic co-authors and advisors. Link below!
I'm hiring! I have 2 open positions:
🔬 Postdoc
🧪 Research associate
We study how animal multicellularity evolved by exploring the molecular logic of cell adhesion using cell biology, 'omics, and tool-building in non-model organisms.
Come join us!

This paper started as an idea @albertomarina.bsky.social had many years ago… which of course means he was right all along 😄. Some of us just needed a few years (and a lot of experiments) to catch up.
Grateful (and slightly humbled) to be part of this. Thanks Alberto!

After >10 years of our lab studying bacterial cGAS-like enzymes, @hobbslabutah.bsky.social finally reconstitutes viral sensing in vitro and discovers how these ancient receptors sense phage protease enzymes to detect virion assembly and activate antiviral immunity

New preprint: Cyclic tri-adenylate signalling by a Panoptes anti-phage guard system with a CARF-TM effector. Great work led by Sabine Grüschow

This is kinda bonkers.
In addition, 20 amino acids were found on Ryugu, along with uracil and vitamin B3. These have been found in other instances, but since the samples from Ryugu were collected directly from the asteroid and delivered in sealed capsules, contamination on Earth could be ruled out.
Really cool work!
How can we tap into the enormous functional diversity of microbes on this planet?
Join us at EMBL Heidelberg (8–10 Dec 2026) to learn about ongoing efforts to decode gene function and organisation in human gut microbes, and present your science.

Discovery of a Genetic Toxin-Antidote System in Vertebrates
hat tip to @asaflevylab.bsky.social
Excited to share our latest work! 📝
We measured the fitness effect of 136 AMR genes and found that many are neutral or even beneficial without selection. 🤯🧬
Oxygen availability can flip their fitness and our stochastic model indicates that oxygen fluctuations help maintain them.

Previous thread for the preprint:
bsky.app/profile/did:...
Final version @nature.com of our paper describing unconventional multicellular development in a choanoflagellate inhabiting an extreme environment. A ton of new data since the first @biorxivpreprint.bsky.social preprint (which we've kept updating).
A brief 🧵 (carried over from the old place)
➡️ preprint from the lab! Bacteria have loads of antiviral defences in their mobile genetic elements (MGEs). So when MGEs move between bacteria, the defences move with them, generating a fast turnover of defences in bacteria. But what about the antiviral defence turnover in the MGEs themselves? 🤔

Published version of our work on diversity-generating retroelements!
We reconstituted a phage DGR in E. coli and deployed high-throughput methods to identify factors influencing the activity of this system. #microsky
