Why are some species widespread while others are found only in small, isolated areas? A study in Nature Communications shows that species with narrow ranges, and thus higher extinction risk, are often island-restricted, poor dispersers, and have evolved relatively recently. #evosky 🧪

🚨 We’re hiring! 🚨 The Integrative Viromics Lab @UCalgary 🇨🇦 is looking for a Lab Technician! 🔬 Phage isolation & culture 🧫 Anaerobic chamber work 📦 Lab management & student mentoring Apply now & help us explore the virosphere! You must have work authorization to work in Canada already.

Thrilled to share our two latest papers with the @tcostalab.bsky.social lab! In the first, we uncover a new mechanism of satellite transfer: cf-PICIs hijack tails from diverse phages to spread across species. @imperialcollegeldn.bsky.social www.cell.com/cell/fulltex...

📢Preprint out! Excited to share my final work from the @soreklab.bsky.social! We mined phage dark matter using structural features shared by anti-defense proteins (viral tools that help phages bypass bacterial immunity) to guide discovery. Found 3 new families targeting immune signaling!

1/46 Hey folks, we have a new paper out on the MuLTEE. Strap in and I’ll tell you the story of how this “little paper on polyploidy” turned into the most data rich paper our lab has produced, largely thanks to the leadership and work ethic of @kaitong25.bsky.social. www.nature.com/articles/s41...

Happy to announce that MEDI, our method to quantify dietary intake through metagenomics is out now. 🧬 🧪🧫🦠 www.nature.com/articles/s42... #metagenomics #microbiome #microbiomesky So what is MEDI? A combination of two things:

Delighted to share this paper out via Virus Evolution: academic.oup.com/ve/advance-a... in which we develop and assess a quantitative method to infer phage and bacterial mutations driving changes in infection phenotypes arising in coevolutionary dynamics. a 🧵 about people (and some science)

We interrupt your regularly-scheduled chaos to bring you some cool microbiome science. 🦠 🖥️ 🧬 "Longitudinal phage–bacteria dynamics in the early life gut microbiome" now out in Nature Microbiology. We wanted a way to measure bacteria and phage in metagenomes 1/ www.nature.com/articles/s41...

Delighted that @tarnopol.bsky.social’s paper (dissertation ch.) is online @currentbiology.bsky.social! “Experimental horizontal transfer of phage-derived genes to Drosophila confers innate immunity to parasitoids.” Phage toxin genes became a feature of insect immune systems millions of years ago…👇🏼

I’m so excited to share that some of my grad work in the @aaronwhiteley lab is now available on bioRxiv! We used an AlphaFold-multimer screen to uncover how a bacterial NLR-related proteins senses multiple phage-encoded proteins to confer phage protection. Link: www.biorxiv.org/content/10.1...
