The Thermo Fisher situation keeps getting worse. We've now collected 450+ problematic images presented as verification data in TF's antibody catalog. This includes:
🖌️ Dozens more images with duplications or painting
🖨️ Hundreds of blots that all share the same background (behold slideshow below)
How can we learn tissue mechanics directly from cell patterns and images?
In our new preprint, we introduce VertAX, a differentiable vertex-model framework in JAX for simulating epithelia, inferring parameters, and designing target tissue behaviors.

Our review article is now available in Annual Review of Condensed Matter Physics: “Full-Integer Topological Defects in Polar Active Matter.” @luizaangheluta.bsky.social @emmalaang.bsky.social doi.org/10.1146/annu...
We present a new mechanism for triggering the flocking transition in epithelia, involving extensile polar defects and domain walls. Very happy to share this work, done in great collaboration with the @luizaangheluta.bsky.social group.

Densely packed epithelial tissues appear mechanically arrested at tissue scale, but their cells move in subtle, coordinated ways.
