Fresh out of the lab! Our new preprint is now up on BioRxiv, exploring how the beneficial bacterium Pseudomonas putida controls its T6SS nanoweapon. It turns out the Gac/Rsm pathway acts as a strict molecular brake on the system. 👇 (1/4) Read the full preprint here: doi.org/10.64898/202...

🧬 Even Earth's most abundant enzyme makes mistakes. Rubisco fixes CO₂ for nearly all life but wastes ~20% of potential crop yield on a 3-billion-year-old side reaction. We built a microbial sensor that finally makes it visible & tinkerable in living cells. www.biorxiv.org/content/10.6...
