I've been working on Surface Morphometrics for a new version (coming soon), and made some significant (AI-assisted) performance improvements, especially in pycurv (20-50x!). If you've had technical issues or just felt like it was too slow, give it another try! #teamtomo github.com/GrotjahnLab/...

Legendary morphometrician Fred L. Bookstein (1947–2026) passed away (news by Hugo A. Benítez). Made the analysis of morphological shapes rigorous and mathematically justified. Paleontology here benefitted from the geometric morphometric innovations the most.

We extend our Surface Morphometrics pipeline to measure membrane thickness.
Alongside many biological findings, we show that our 3D measurements closely match in vitro vesicle measurements from 2D EM (collab w/Neal Waxham and Fred Heberle).
