🚨 Second preprint of the week!
We uncover the multiscale dynamics of active viscoelastic buckling in epithelia.
We harness these mechanical instabilities for synthetic morphogenesis.
Led by @onenimesa🙌. Theory by Marino Arroyo and team.

A new optical biosensor can probe the activities of native GPCRs in live cells, and, unlike typical sensors doesn’t interfere with downstream signaling and can be deployed in many cell types with only a single construct. scim.ag/4cno5L1 @scisignal

Sound-sheet microscopy is born! Congratulations to Baptiste Heiles, lab members and collaborators at the Shapiro Lab (Caltech) and Gazzola Lab (NIN/KNAW) for this scientific achievement 🚀.

A new method reported in Science allows the generation of 3D ultrasound images of gene expression and 2D ultrasound images of capillary vessels. The approach enables fast, deep, and volumetric imaging of living opaque organs labeled with echogenic reporters.

ALT A cross-propagating ultrasound wave exposes a thin tissue section that contains blood vessels feeding a tumor. The wave interacts with sound-scattering probes (displayed in orange gold) that are genetically expressed in cancer cells or are injected in the bloodstream to reveal capillary vessels. White contour lines indicate previously scanned tissue sections and the total volume explored by this sound-sheet microscopy technique.

In our new preprint, we study the physical aging of biochemically active condensates formed by an engineered Tau protein into disease-linked amyloid fibrils — and investigate whether small molecules can counteract this transition. @BanerjeeLab_UB

Excited to share our work out in @CurrentBiology ! We find that SKAP's binding to microtubules *reduces* friction at the kinetochore-microtubule interface and increases attachment stability under force. Congrats to postdoc Miquel @RosasSalvans and all authors! With @Caleb_J_Rux and Moumita Das.

Just posted the most biologically important photopharmacology story we've had in the last few years.
Ditched the photoswitch design principles we used for the last 10 years, & started all over again.
And now it will work in vivo.

Impressively strong magnetic effect on fluorescence of engineered protein
Opens up new avenues for magnetogentics
2 Jun 2024
Meet MagLOV: an engineered protein that responds STRONGLY to magnetic fields.
This is a fluorescence timelapse of MagLOV in E. coli. We're waving a (small) magnet under the plate.
Can you tell where the magnet is?
Want some? It's on Addgene now! addgene.org/219957/

We used light to herd cell growth with @toettch lab! Optogenetics is pretty cool. Super fun collab. and exquisite data from @KevinSuhhh* and @RichardHT_*. Video: blue light pattern--> sheet of living tissue rearranges into creepy eye. See @toettch for🧵. biorxiv.org/content/10.1101/…

How do bacteria grow and move in large groups where cells appear adhered to each other but can move freely? Using capillary forces from thin layers of water! Check out our new preprint with Matt Black, Chenyi Fei, @RicardAlert and Ned Wingreen: biorxiv.org/content/10.1101/…

Some of us were asked by @CellCellPress about the future of mechanobiology. In all likelihood, 20 years from now we'll see we were all wrong. Any thoughts? What did we miss?🤔🔮👇authors.elsevier.com/a/1j8Ml…

Beautiful, powerful methods to quantified lipid flow in cells, demonstrating the importance of non-vesicular lipid transport. Congratulations to the team.
21 May 2024
Here’s the big one: In collaboration with @Honigmann_Lab, @LabShevchenko, Björn Drobot and Martin Hof we present a general workflow for imaging the localization and transport of individual lipids in cells and mapping their metabolism.

Hello, my absolutely lovely membrane peeps! Would you maybe, pretty-please, let me proudly steer you to a MINI-REVIEW I recently wrote? It’s on asymmetric membranes in general, and differential stress in particular—subjects that I am massively interested in right now!
