Excited to share our new @natecoevo.nature.com paper. We identified microbes found across nearly all ruminants that act as the functional backbone of both the rumen ecosystem and the host, with major implications for food security and climate change mitigation. (1/8) www.nature.com/articles/s41...

New discovery in ulcerative colitis: a bacterial toxin that kills macrophages and increases inflammation, which could be the foundation for a new treatment science.org/doi/10.1126/... science.org/doi/10.1126/... @science.org

Hot off the press! Our latest paper led by @fernpizza.bsky.social, understanding how plasmids evolve inside cells. These small, self-replicating DNA circles live inside bacteria and carry antibiotic resistance genes, but also compete with one another to replicate. 1/ www.science.org/doi/10.1126/...

I'm happy to share a perspective that @soniamodilevsky.bsky.social and I wrote about a new and exciting paper in @science.org with big implications for IBD. Check it out: A bacterial toxin disarms gut defenses against inflammation | Science www.science.org/doi/10.1126/...

🚨 Big news! Infection and Immunity is now open access! 🌍🔬 That means wider visibility & impact for your research. Worried about fees? 💸 Check out how IAI stacks up against other journals—you might be surprised. #OpenAccess #SciComm #Microbiology

Takeaway: WHIX is a microscopic marvel—a tiny domain with enormous potential. From its double-sided toxic punch to its delivery finesse, it’s the new T6SS delivery domain on the market. Stay tuned for more cool stories about WHIX and about our new model bacteria, Aeromonas jandaei! 8/9

Our new story on #T6SS WHIX effectors and bacterial warfare is out in @plosbiology.org. It has a lot more data than the original bioRxiv preprint, so take a look even if you’ve read that. 🦠 What did we find? A thread... 1/9 journals.plos.org/plosbiology/...

Very happy to be a part of this beautiful study led by Drs Maria Cimini and Raj Kishore showing a role for SAA3 amyloidosis after myocardial infarction (MI) and how SAA3 loaded exosomes can drive injury www.sciencedirect.com/science/arti...
