ICML is happening in Seoul this year, and I’ve been getting several messages about lab visits. Who else will be in town and would like to meet? @milot.bsky.social lab and mine are planning a dinner on July 7th, after the reception. Let me know if you’re interested!

I received wth great sadness the news of the passing of our dear friend & colleague Ana Clara Carrera. One of the most recognizable faces of the @cnb-csic.bsky.social for many years. Her enthusiasm & character touched all of us who had the fortune of crossing paths with her. May she rest in peace 🫶🏻

Archaea the hornets of the microbial world. Discuss. www.biorxiv.org/content/10.6... TLDR: Archaeon kills bacterium with secreted phospholipase. Pretty nifty way to kill bacteria if you are a microbe with a very different lipid make-up, I reckon. No need to worry about accidentally killing yourself.

🌊 Protecting our oceans starts with action.  The 30x30 initiative aims to protect at least 30% of lands, waters and ocean by 2030 to support biodiversity and climate resilience.  A healthy ocean needs long term commitment, collaboration, and knowledge driven solutions. 💙  #30x30 #OceanHealth

What if a key gene behind ocean photosynthesis doesn’t belong to microbes, but to their viruses? This study shows that a phycoerythrobilin synthase gene, once suspected in cyanobacteria, is actually a cyanophage gene, revealing how viruses influence ocean productivity. Read more: buff.ly/aSkAlsZ

Fascinating new science in @pnas.org! Turns out "aerobic" soil bacteria have a survival trick. When oxygen drops, they adapt by hybridizing fermentation with carbon storage to stay alive! Nature's resilience is unmatched. @greening.bsky.social www.pnas.org/doi/abs/10.1...
