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.

A timelapse movie (unpublished data) from the lab.

In the movie, the nucleus is moving towards the base of the polarized root hair cell.

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!

Tracking has always been at the ❤️ of the scientific method, from planetary motion to single particles.

Weiqing’s thesis intro on tracking was so beautiful we turned it into a perspective in JCP who then selected it as a #Scilight.

Take a look! 😊

Internet people, please help me to decide on the logo for #bigvolumebrowser, a multi-volume 3D viewer plugin for Fiji I'm working on. Please vote by replying with a number or liking one that was already mentioned. My favorites are 6, 7, 8 and 10 so far.

Hello dear diary, today I've added some minor features, like highlighting boxes and canvas selecting objects + manual transform mode. Small update, mucho trabajo, but it should be helpful for user experience #bigvolumebrowser

I found these immune cells just finished mitosis but their midbody is still yet to be resolved. How cool? If you zoom in to the midbody, you can see its classical shape just like in the textbooks. I love these little details.

15 years in the making, we confirmed that mitochondria - the powerhouse of the cell - have an unusual localization in patients who experience psychosis (including schizophrenia and bipolar disorders). You’ll never guess what kind of patient cells we used to make this discovery… 🧵
