Our work characterizing how mutational bias is influenced by the local sequence context beyond trinucleotides is out now @pnas.org! We also showed which motifs are most prone to mutations caused by strand misalignment, revealing several new hotspots! 🧬 www.pnas.org/doi/10.1073/...

Our study comparing promoter existence and emergence in random vs genomic DNA is finally published!!! TLDR: the E. coli genome has more promoters than random DNA (even in intergenic regions), and promoters emerge ~3x more readily from random DNA than genomic DNA. (1/2)

New preprint from my lab (with Arya Kaul, @fernpizza.bsky.social, and @brinda.eu), in which we explore new genes hitchhiking on the beneficial deletion that fused them together, and find them in the LTEE, M. Tb/bovis, and across the bacterial tree of life

As we close the year, the ISME Early Career Scientist Committee is glad to spotlight @duhitasant.bsky.social , Postdoctoral Researcher at Rutgers University, and her paper “Eco-evolutionary robustness of wild bacterial communities to experimental perturbation”. doi.org/10.1093/isme... (1/2)

This is totally worth 5 minutes of your time and probably should be in every biology class. Nature is awesome. neal.fun/size-of-life/

How do bacteria deal with double costs? And how costly are unusual levels of mistranslation anyway? In short - antibiotics are more of an issue than less/more mistranslation, but the latter changes how populations deal with antibiotics. For the long story, check out our new paper!

A fun little side project I've been working on with @stepadenisov.bsky.social , Mato Lagator, and Andreas Wagner: "Strong promoters are mutationally robust". Briefly... www.biorxiv.org/content/10.1...

Massive undertaking with @teppo-h.bsky.social and others out. We studied 4 years (!!!) of synthetic 23 microbial species community evolution with/without antibiotic. Resistance mutations occurring over years led to stepwise restructuring and ultimately recovery of undisturbed community composition.
