Cells can form patterns within themselves just like embryos do. How? Connie Yan's new preprint shows how the anterior-posterior cytoskeleton pattern in Stentor is dictated by regionalized scaffolding proteins

So called microtubule organizing centers (MTOCs) are not "organizing centers". They don't control their position (network center), nor MT orientation, length and shape (network shape). The actual organizers are MTs, molecular motors and regulators of MT +ends. MTOCs nucleate MTs.
Let's rename MTOCs.

ahah IT WORKS look it's a C² dual quaternion B-spline!!

this is interpolating *poses* in dual quaternion form, coupling position and rotation, instead of treating them independently (this is a really neat thing!!)

In our new #Preprint, we pilot a revolutionary new idea: no supplemental data (it has 21 figures, though):

Multiplexed imaging of G-proteins and ERK activity upon activation of CaSR
We have previously shown that the calcium sensing receptor (CaSR) activates different G proteins and second messengers in single cells, and that GPCR and G protein-mediated ERK activity can be highly ...

It ships many new features, detailed below, but that are articulated around the following:

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.

I'd only dabbled with napari, but needed to use it for a paper we're writing. This is a quick post about getting started: from installation to a folder full of thousands of processed images, with gotchas along the way.

We are planning the build of a light sheet setup and are considering a Powell lens to generate the sheet.
I've not been able to find a discussion of the pros and cons in literature, so if you ever used a Powell lens or have considered using one in your setup, I would love to hear your opinion. THX!
