It's funny how we stigmatize being wrong in science. There's nothing better in science than being wrong and getting to change your mind about something. Any day you were wrong is a day you get to learn something new!

Registration is open for the Biotic Control of Bacteria meeting, hosted by MGen Deputy Editor-in-Chief Dr Conor Meehan. Explore innovative approaches to controlling bacterial growth and network with leading researchers in the field. Find out more: https://microb.io/3Qv6k5B

Here’s the latest preprint from my work on evolved resistance to Type VI Secretion system (T6SS) weaponry, funded by a @wellcometrust.bsky.social Sir Henry Wellcome Fellowship. So happy to see this out! www.biorxiv.org/content/10.6...

New pre-print from us showing how biophysical traits like cell surface hydrophobicity dictate Pseudomonas aeruginosa aggregate architecture & shield cooperators from cheaters. May have relevance for understanding social evolution in chronic infections. 🧬🧫 doi.org/10.64898/202...

🚨 Calling all UK microbiologists 🚨- MEEHubs Registration is now OPEN! Come join our hub at ☀️ @manchester.ac.uk ☀️

How does treatment induced antibiotic resistance happen in real-world infections? We analysed 25k Pseudomonas isolates from 180 patients in a clinical trial to find out! TLDR: The ecological and evolutionary paths are surprisingly diverse & complex even in patients receiving identical treatment…

New preprint! Ever wondered why only a fraction of genomes encode CRISPR immunity? 🧬 🦠 Turns out CRISPR is rarely beneficial against virulent phages, being most beneficial against those for which resistance mutations are rare! An epic effort by Rosanna Wright www.biorxiv.org/content/10.1...

🚨 PhD Studentship available! 🚨 We're hiring a UK student to start in Oct '26 via the BBSRC CODEM scheme. Full studentship plus £10k top-up PA. Study the mysterious ZOMBIE PHAGES 🧟 🦠 with our fabulous @mermanchester.bsky.social and @uommib.bsky.social communities! www.findaphd.com/phds/project...

Happy to share our latest T6SS review: nature.com/articles/s41... Thank you, Jan, Danny (@dannyjamesward.bsky.social), Joana (@joanampereira.bsky.social), as well as reviewers and editors @natrevmicro.nature.com!

Can we leverage bacterial competition for targeted replacement of harmful strains? Maybe! Our recent piece in @natmicrobiol.nature.com provides a theoretical framework and a set of experiments to show what it might take: www.nature.com/articles/s41...

Had a fabulous time at the @wellcometrust.bsky.social ECR meeting today! Thanks for sharing some inspiring science and innovations to improve research culture 🧑‍🔬 and sustainability 🌱

So happy to share this! Bacteriocins were first discovered over 100 years ago, but what do they actually do? We look at >1000 bacteriocin plasmids and find links to virulence and antimicrobial resistance, and frequent bacteriocin sharing in Enterobacteriaceae. www.nature.com/articles/s41...

Hello everyone, take a look at my cool bugs from the Microbial Dark Matter phylum Saccharibacteria! These ultrasmall bacteria (in green) track down Actinobacteria hosts (not in green) and grow on the host cell envelope.

Open position to work on Type IX secretion (#T9SS) in our lab, in collaboration withe the group of Eric Reynolds at the Dental School of the University of Melbourne. Please spread the word, and forward to anyone potentially interested ! Apply here: emploi.cnrs.fr/Offres/Docto...

🧐Checkout our preprint revealing the stepwise firing💥 mechanism of a Contractile Injection System @xujwet.bsky.social&@chipericson.bsky.social trapped the complex by structure-guided engineering🧪 in multiple intermediate states and imaged them by multimodal #cryoEM❄️🔬 www.biorxiv.org/content/10.1...

Metabolic interplay drives population cycles in a cross-feeding microbial community www.nature.com/articles/s41... #jcampubs

Phage "satellites" that produce capsids but have no genes to produce tails have puzzled scientists for a long time. These are abundant as prophages in bacteria, but it was unclear how they can infect without tails Now, Penadés & co show that they hijack tails from other phages. Incredible!

New preprint bubbling up in our group for a while: "Phase separation and coexistence in spatial coordination games between microbes" www.biorxiv.org/content/10.1... Generalizes findings of phase separation in microbes using T6SSs to a broad range of interaction mechanisms. Li + Steinbach et al.

Does your lab perform killing assays? TL;DR: we’ve identified a problem that can bias the outcome of killing assays, making antagonism look stronger than it really is. Adding a simple extra step can mitigate this bias!  Out now at #MicrobioJ www.microbiologyresearch.org/content/jour... 1/n

Check out our latest preprint! We show that the same antibacterial toxin requires different immunity proteins depending whether it’s intra or extracellular

#Bacteria use weapons to outcompete rivals, but what happens if they're transferred? @prokaryota.bsky.social @jdpal.bsky.social &co show that HGT of toxin #plasmids is rare but recipients can thrive under relaxed nutrient competition, reshaping bacterial warfare @plosbiology.org 🧪 plos.io/43vC3X7

Hi folks, I'm excited to share a whale of a tale (sorry, bad pun), where we engineer snowflake yeast to express sperm whale myoglobin, and explore how oxygen-binding proteins may have helped overcome anatomical limitations to early multicellularity. 🧪 #MEvoSky journals.plos.org/plosbiology/...
