🚨🚨🚨Calling all Caulophiles and Alpha aficionados - stayed tuned for a virtual CauloCon in early 2026. And HOPEFULLY an in person alpha meeting in 2027!! DM me or @chienlab.bsky.social w questions or to stay in the know.

Please re-post: If you know (or are!) somebody who might fancy doing a PhD (Oct 2026 start) in my group @oxfordbiochemistry.bsky.social, working on chromatin evolution in prokaryotes (or other things we're interested in), please have a look at www.bioch.ox.ac.uk/supervisors-...

PhD opportunity, please share: We are looking for a prospective PhD student to start in October 2026 who is excited about bacteria (Klebsiella pneumoniae), how they interact, and how they exchange DNA. All details can be found on the funder website 👉 gw4biomed.ac.uk/developing-c...

📢 Interested in chromosomes and microbes thriving at the edge of life?PhD project in York-UK on chromosome segregation in #Archaea. Supervised by me, @Steve Quinn & @georgerheath.bsky.social www.findaphd.com/phds/project... Open to Applicants Worldwide! 📅 January 6, 2025 #microsky #archaeasky

New preprint reveals bacteria can't just collect all resistance genes like Pokemon cards. We found mutually exclusive evolutionary pathways to multidrug resistance in E. coli & P. aeruginosa - some resistance mechanisms actively prevent others from coexisting www.biorxiv.org/content/10.1...

What was antibiotic resistance like before we ever used antibiotics? How did we change what antibiotic resistance genes looked like over 100 years? Our paper looking at resistance genes from a century of NCTC historical isolates now out in mGen: www.microbiologyresearch.org/content/jour...

Do plasmids evolve faster 🐇, slower 🐢, or just like chromosomes 🧬? In our new paper, we tackled this question using theory, simulations, bioinformatics, and experiments! 👇 Check out all the details in Paula’s thread! Hint: 🐇 (most of the time)
