Felix Zhou's u-Segment3D is out:

www.nature.com/articles/s41...

It leverages 2D cell segmentations from orthoviews to generate a ‘consensus’ 3D segmentation.

It does a great job on segmenting densely packed samples, and we have used the algorithm in many applications.

We have observed a beautifully strange phenomenon of phase separation by human monocytes placed on soft matrix, which do it for survival.

We model it by incorporating the Cahn–Hilliard equation with a Turing mechanism of local activation/global inhibition

The Python Software Foundation was recommended for a $1.5M grant from the National Science Foundation. The terms of the award said PSF could not work on DEI, whether or not the grant funding was used for it.

PSF therefore declined the funding.

Science suffers, but commitment to core values remains
TLDR; The PSF has made the decision to put our community and our shared diversity, equity, and inclusion values ahead of seeking $1.5M in new revenue. Please read and share. pyfound.blogspot.com/2025/10/NSF-...
