🚨🚨New paper out in @natcomms.nature.com!!

Come for the first large-scale analysis of plasmid copy number across species,
stay for one of the most intriguing results of my lab: universal scaling laws in plasmid biology! 📈🧬

Universal rules govern plasmid copy number - Nature Communications
Plasmids exhibit a broad range of sizes and copies per cell, and these two parameters appear to be negatively correlated. Here, Ramiro-Martínez et al. analyse the copy number of thousands of diverse b...

My first lead author paper is out with Ben Kerr and @alisonfeder.bsky.social! We found that making an antiviral too strong can sometimes make resistance easier to evolve. This has implications for how we design drugs, choose doses, and think about viral evolution in the face of treatment. (1/n)

Excited to share our latest work with @albertomarina.bsky.social and @avigdoreldar.bsky.social labs, where we decipher the mechanism by which SPβ-like phages sense the SOS response to control the lysis–lysogeny switch. www.biorxiv.org/content/10.1...

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.

🚨Preprint alert - this is a big one! We transfer the revolutionary power of TnSeq to bacteriophages.

Our HIDEN-SEQ links the "dark matter" genes of your favorite phage to any selectable phenotype, guiding the path from fun observations to molecular mechanisms.

I'm looking for studies where both Illumina and ONT sequencing were performed on the same samples from soil, human, ruminent, and other sample types for comparison. Bonus if those studies include PacBio data.
