🎉 New year, NEW PREPRINT!

Bacteria exhibit astonishing genetic diversity, but where do new genes come from?

My best friend Arya Kaul (/labmate in the @baym lab) investigates how advantageous deletions can spawn new genes - "deletion-born fusions." 🧵:

What is the best strategy to win any contest?

Eliminate your opponents of course.

Recently, my friend @fernpizza.bsky.social showed how plasmids compete intracellularly (check out his paper published in Science today!). With @baym.lol, we now know they can fight.

🚨 Excited to share our new paper is out! 🎉
We show how interactions within gut microbiomes allow certain antibiotic-resistant E. coli strains to persist even without antibiotics, helping explain how resistance is maintained in the human gut.

✨Célia Souque just showcased the outcomes of the 12th Microbial Bioinformatics Hackathon at IMMEM XIV.

She brilliantly presented the first sneak-peek of PORT – Plasmid Outbreak Reporting Tool! 🧬
Looking forward to continuing this collaboration with PORT!

hey bluesky 👋 visa hurdles mean I’m looking for opportunities outside the US. I’m a computational biologist (bacterial + phage genomics, postdoc in Koonin’s group @ NIH). I am interested in teaming up on funding apps. reach out if this resonates!

(1/7) Very excited to share my first PhD preprint on the interactions of two of my favorite mobile genetic elements: phages and group II introns!

This paper has been a long time coming: We looked at the genomes of historical bacterial samples over a century to look for trends of antibiotic resistance genes, finding multiple instances of them in infections before the age of antibiotics, but an increase in both frequency and mobility after

Our review is out in Nature Reviews Genetics! rdcu.be/d5AY2

We show how phylogeny-based methods can resolve the problem of non-independence in genomic datasets.

These methods must be considered an essential part of the comparative genomics toolkit.

Don't know how to do polls in Bluesky, but am very curious to know how what the #microsky thinks.

Genes that increase fitness in natural conditions are:
A. Over-represented on plasmids
B. Over-represented on the chromosome
C. Evenly distributed between plasmids and the chromosome

For circular plots, I have found that out of the box elderly BRIG beatsonlab.com/softwares/br... remains the best. Otherwise for more custom plots I usually go with circos-like packages (like pyCirclize in Python) but it is much more work

That's low-key one of my favorite thing about Oslo - the city center is very often car free, and the few cars are often electric, which makes them much less audible.

Going to back to a 'proper' big city (Stockholm) for a week felt weird!
