📌 Tracking cell dynamics just got smarter!
We use Bayesian linking algorithms — KOFT and SKT — implemented in our ByoTrack 🐍 Python library.
Kalman filters + optical flow for links & mitosis detection.

Zoom into a human cell infected by Shigella, the bacteria behind dysentery. Using cryo-EM, @leaswistak.bsky.social and team revealed how it pierces cells with molecular syringes. Stunning science at the nanoscale.

and with the uniform Laplacian we get a quite funny artefact! (most likely due to the straight cut from the midbrain, which has a few very large triangles)
