What does E. coli do when food runs out? We spent years looking at it with our quantitative glasses, and now put the final preprint online: www.biorxiv.org/content/10.1... Congrats to Théo Gervais for the 'tour de force'!

What do bacterial cells do when they run out of nutrients? Although most bacterial studies focus on cells in exponentially growing states, in the wild bacteria likely spend most of their time slowly starving to death. 1/n www.biorxiv.org/content/10.1...

I'm puzzled 🤯 By now, we've spent lots of time measuring the effect of growth rate fluctuations on cell-to-cell variability of GFP concentration using various promoters in E. coli. However, we never observed the negative correlation reported by Patange et al. Now reported by Proenca et al too! 1/n

Still have to read the full article - but from the tweetorial and the figures it sounds so cool 🤩

Switzerland!! 🤩 I lost my train card at a gas station last weekend. Went back after realizing one hour later but couldn't find it... Someone had collected it, and send it back by post, without even writing any sender address. Big big thanks to this anonymous person.

New preprint! doi.org/10.1101/2024... Yet another study where we highlight how noisy gene regulation is in single bacterial cells 🫨 After we measured several promoters regulated by LexA in the mother machine, L. Galbusera and @erikvannimwegen.bsky.social did a great theoretical analysis 1/n

Nice!! (link for download: doi.org/10.1016/j.ce...)
