Just finished my first @skypeascientist.bsky.social session and feeling so full of enthusiasm for science from the lovely questions the middle schoolers asked. However I did compare phage specificity to someone who makes chairs ending up in a coca-cola factory and not knowing how to make anything 🤦‍♀️

When is an antiphage mechanism an evolved defence adaptation? This question has been on my mind for so long, because despite the field’s rapid progress there is currently no widely agreed framework in place to answer it. So @brownlab.bsky.social and I wrote this, and I'm happy to share the preprint!

I'm excited and grateful to share that I have been awarded a Marie Skłodowska-Curie postdoc fellowship for my work with @annechevallereau.bsky.social at @mmsb-lyon.bsky.social. I feel incredibly lucky and I'm looking forward to getting to work on all the phage-y experiments we have planned 🧫

Two conferences two weeks apart, thank you to everyone who came and chatted to me at my poster (or in general) at the Phages.fr conference in Nancy and the @microbiologysociety.org #MicroEvo25 conference in Liverpool. It was great to show the first data from my postdoc and get advice and feedback

✍️ We had a great time writing this Spotlight article on one of our favorite topics: how phages interact with each other! 🦠 From cooperation to competition, phage-phage interactions reveal a fascinating layer of microbial life that’s often overlooked. A piece crafted by the talented Josie Elliott!
