🦠 Mycobacteria aren't just tough, they're interior designers! 🦠 Check out our latest #preprint 🚨, led by our PhD student @camimille.bsky.social , where we show that #Mycobacterium tuberculosis builds secret cytoplasmic membranes to adapt its metabolism and sneak past immunity 🤫 Thread coming soon!

The cell looks like Inkay Pokémon🔬 — yellow glowing arms, pink heart. Under attack by cyan bacteria🦠, but it’s just vibing on the glass, dancing🪩, unaware of the aftermath☠️. #FluorescenceFriday #Microscopy #CellBiology #mechanobiology @pasteuredu.bsky.social #hostpathogeninteraction @pasteur.fr

A new combination technique enables DNA sequencing and high-resolution imaging in intact cells — offering new insights into progeria and aging. broad.io/expansion-in-situ @jbuenrostro.bsky.social

Harvard president receives standing ovation during commencement.

Just published, expansion in situ genome sequencing, where you can sequence DNA while still inside the cell, mapping its organization relative to proteins and other markers, with the help of expansion microscopy! Led by @jbuenrostro.bksy.social. www.science.org/doi/10.1126/...

The new issue is out! 👉 cell.com/cell/current On the cover, Beckwith and Brunner et al. uncover that chromosomes self-organize into their characteristic mitotic rod shape through the formation of large and extensively overlapping DNA loops 📷credit: Andreas Brunner.

Cohabitation shifts gut bacteria to protect the liver: Sharing gut bacteria via cohabitation, notably Rikenellamicrofusus, boosts isoflavone conversion to biochanin-A, reducing liver injury from acetaminophen overdose by enhancing liver cell metabolism and defense www.cell.com/cell-host-mi...

This week in Science, researchers delve into the #mathematics that shapes growing rose petals. 🌹 Explore our latest issue—featuring a new print design: scim.ag/42DasUT

How do intracellular #bacteria breach vacuoles to enter the host cytosol? @leaswistak.bsky.social @matthijnvos.bsky.social @enningalab.bsky.social &co show that #Shigella uses its T3SS system to damage endomembranes via mechanoporation to initiate cytosolic access @plosbiology.org 🧪 plos.io/4jXrr9Z

Watching fission yeast divide is cool🦠. But showing it with a kymograph? Even cooler 😎, shows it all—mitosis, cell wall—packed into spatiotemporal magic🪄. Flattening time into 2D just makes it easier to understand. #FluorescenceFriday @pasteur.fr @pasteuredu.bsky.social #Microscopy #Microbiology🔬

When cutting-edge tech, brilliant minds, and powerful science communication come together — that's Institut Pasteur! Grateful to be part of this inspiring community. #PasteurCommunity #ScienceLife
