The risks of antimicrobial resistance have been increasing, while harmful biocides have continued to be used where they are not needed.

The government must act now to reduce these risks and safeguard our future.

Last week's seminar featured excellent talks from @fionapoulter.bsky.social on understanding the evolution of epidemic Pseudomonas aeruginosa and Holly Richardson on why heterogeneity matters: predicting antibiotic resistance in cystic fibrosis.
Thanks to @microbesng.bsky.social for the nice snacks!

1) Being apolitical is a myth. (Hyde seems to agree.) We all approach the world with our beliefs & biases. Pretending scientists are superhuman is silly & even dangerous. Thankfully, the scientific process is set up to mitigate such biases through transparency & open debate.

“Australians can now live & work freely in the EU for 4 years and vice versa

That means they now have 𝒎𝒐𝒓𝒆 EU rights than British people. Free movement offered millions of us fantastic opportunities but Brexiteers slammed that door shut, most shamefully on their own children”

Here is it! Super new science from us on horizontal gene transfer & bact defense systems! Liyana OW YONG discovered the first-of-its-kind defense factor AbjA that triggers 'abortive conjugation' as a defense mechanism, by targeting the T4SS! How neat?! #MicroSky 1/7

Everyone but Trump Understands What He’s Done Allied leaders know that any positive gesture they make will count for nothing.

Trump does not think strategically, historically, geographically, or even rationally. He does not connect actions he takes on one day to events that occur weeks later. Allied leaders know that if they help him in the Gulf, he won't be grateful, or even remember

From Trading Genes to Crafting New Tricks: How Horizontal Gene Transfer Potentiates the Emergence of Novel Functions

Horizontal gene transfer is often depicted as a process distributing pre-existing functions to novel genetic backgrounds. Yet HGT can also increase the rate of functional innovation after transfer. Here's a brief review on the topic: ecoevorxiv.org/repository/v... #evosky #microsky

Research Associate in Microbial Genomics:Manchester This postdoctoral research position is part of a Cystic Fibrosis Canada Early Career Investigator Award funded for 3-years led by Dr. Fabrice Jean-Pierre and Dr. Fiona Whelan. The aim of this project is to identify the genetic changes that arise in the Pseudomonas aeruginosa genome following perturbations – such as antibiotic treatment – in an in vitro system. The PDRA will use a large dataset of P. aeruginosa genomes and experimental metadata to predict key mutationsto the organism.

📣 The Whelan lab is hiring a bioinformatics postdoc 📣

Together with @fabricejpierre.bsky.social, we are offering a 1-year bioinformatic PDRA position in comparative genomics of Pseudomonas aeruginosa. To find out more please visit whelanlab.co.uk/contact/. Applications close 3 April 2026!

Excited to share our latest work! 📝

We measured the fitness effect of 136 AMR genes and found that many are neutral or even beneficial without selection. 🤯🧬

Oxygen availability can flip their fitness and our stochastic model indicates that oxygen fluctuations help maintain them.

Predicting protein-protein interactions (PPIs) at proteome scale can take months with co-folding models due to the massive all-vs-all comparisons required.

We are excited to announce FlashPPI, a contrastive learning framework that predicts proteome wide physical interfaces in minutes. 1/🧵

I’ve spent a lot of time over the past two years thinking about genome evolution and how recent research revealing complex gene-gene interactions has complicated traditional ‘gene-centric’ genomic approaches to evolution. So here is a review that consolidates these thoughts!

Make no mistake this is a concerted and organised attempt to completely undermine science and expert opinion. This is Covid denialism on steroids and it’s on all of academia to see this for what it is and push back as strongly as possible

Priority effects inhibit the repeated evolution of phototrophy - npj Complexity npj Complexity - Priority effects inhibit the repeated evolution of phototrophy

New paper out! Here's a puzzle: phototrophy, the ability to use light for energy, is one of life's great innovations. It evolved early and transformed the biosphere. But it evolved 2x. Why not just once, why not more? Our work suggests the answer is priority effects.
