🎁 Getting a paper acceptance right before Christmas break is one of the best feelings. 100% recommend. Happy holidays, everyone! 🎄✨

A pleasure and an honour to have received this prestigious grant with my admired colleagues and friends @sanmillan.bsky.social and @asanchezlab.bsky.social . More about AMR under plasmid lens!. My sincere gratitude to @caixaresearch.bsky.social @microryc.bsky.social @esgem-sg.bsky.social

A plasmid golden ratio? 🧬 Plasmid copy number ≈ 2.5% of chromosome size—consistent across bacterial species! pmc.ncbi.nlm.nih.gov/articles/PMC... @jerorb.bsky.social 🧪 #microbesky

In episode 337 TWiM explains a study that examines pathogen presence in ancient humans and concludes that zoonoses emerged 6500 years ago with the domestication of livestock, and determination of universal rules that govern plasmid copy number. This week's special guest: @markowenmartin.bsky.social

This work is finally published! 🥳🧬 Plasmids are associated with very variable fitness costs in their different bacterial hosts. But, what is the contribution of each of the plasmid-genes in these host-specific effects? Study led by @jorgesastred.bsky.social, @sanmillan.bsky.social and myself! 1/14

Our new manuscript is out! A bit of everything cool: Plasmids ✅ Insertion Sequences ✅ AMR Evolution ✅ Microbial Communities ✅ Databases analyses ✅ Mathematical modeling ✅ See the scientific thread below of Jorge Sastre, who has brilliantly led this work with @palomarodera.bsky.social

New paper out! 🔈🔈📣📣 Plasmids promote antimicrobial resistance through Insertion Sequence-mediated gene inactivation. Combining experimental and computational approaches, we unveil how two of the most prevalent bacterial MGE accelerate the evolution of AMR. 🧵👇🏻 www.biorxiv.org/content/10.1...

🚨🚨 New paper in @narjournal.bsky.social! 🍾 Excludons are pairs of overlapping genes that block each other’s expression (basically, reverse operons). We built a tool to identify them in bacterial genomes using transcriptomic data, in an awesome collab led by Iñigo Lasa and Álvaro San Martín. 👇

Had an amazing time at #FEMS2025 last week, where I presented our latest findings on collateral sensitivity mediated by beta-lactamases ☯️ Big thanks to everyone who came by! So proud of my colleagues for their brilliant talks and posters ✨

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)

The must-read of this Summer! 🤩 Congrats to all the authors for this beautiful work 🥳

New paper alert! 🚨 Plasmids promote bacterial evolution through a copy number-driven increase in mutation rate. We combine theory, simulations, experimental evolution, and bioinformatics to demonstrate that mutation rates scale with plasmid copy number. Let's dive in! 🧵👇

This is a legitimately incredible result that hints at something fundamental about plasmids that we don’t yet understand

Super proud of the lab for their outstanding presentations at #FEMS2025 in Milano! Science is better when you work with such a stellar team!🚀✨ @femsmicro.org

It was an honor and a joy to receive the National Research Prize for Young (!) Researchers. The highlight? My grandma greeting the King of Spain. What a day! www.youtube.com/watch?v=oSQP...

Oh this is fantastic 🦠🧫

If you're into plasmid biology, you can't miss this back-to-back by two inspiring teams!

🚨🚨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! 📈🧬 👉 www.nature.com/articles/s41...

Curious about plasmid biology? Our latest paper is out now in Nature Communications! 🚨 doi.org/10.1038/s414... We analyzed thousands of diverse bacterial plasmids to shed light for the first time on a key aspect of plasmid biology: plasmid copy number. 1/7 👇

New mini-review on the respiratory microbiome and its contribution to human health from biotechnology 🫁🦠 @tmcoque.bsky.social @microbiotech.bsky.social enviromicro-journals.onlinelibrary.wiley.com/doi/10.1111/...

Happy International Day of Women and Girls in Science 👩‍🔬🧬 #womeninscience #girlsinscience

Just migrated here from twitter! Hello everyone. Also, I've just put up a super simple (and free) to use APP to streamline experiment design and result analysis of 96 (or 384) wells plate experiments for my lab pals. You can try it here: rosettier.streamlit.app Feedback is very welcome 😁!

Really beautiful day receiving the “Margarita Salas” Award from the Madrid Region! Really proud to share it with my colleagues, friends and family!!
