Capillary interactions drive the self-organization of bacterial colonies - Nature Physics Bacteria tend to live in thin layers of water on surfaces. Now the capillary forces in these layers are shown to help organize the bacteria into dense packs.

Dreaming of a swimming pool? Bacteria are surrounded by water! Water capillary forces organize bacterial colonies into gas, nematic streams, or droplet states. New paper @natphys.nature.com led by Matt Black and Chenyi Fei, with Ned Wingreen and Josh Shaevitz!

Cytoplasmic crowding acts as a porous medium reducing macromolecule diffusion Intracellular transport of macromolecules is crucial for the proper functioning of most cellular processes. Although intracellular crowding is known to strongly alter macromolecule mobility, how cytop...

To what extent does crowding modulate diffusion across the cytoplasm?

The power of custom opto-mechanics AND custom software!

-> Here's a RAMM epi (REPI) microscope I put together. It's just a 2D fluorescence microscope with fast triggering that's mobile and relatively easy to modify. The real advantage here is full programmatic control!

Fig. 5. Emergence of cellular orientation parallel to the tissue interface originates in the basal epithelium and propagates to the internal mesenchymal cells. (A) Diagrams showing explant interface and predicted axis of elongation and sectioned explant showing apical epithelium, basal epithelium and first layer of inner mesenchymal cells in the z-axis. (B) Images and segmentations with cell orientation representation for three z-positions at time point ti. (C) Representative close-up of segmented cells and corresponding nematic order Q score for each z-position. Data are meanΒ±s.d. N=3. No outer mesenchymal cells were quantified at this time point as mesenchymal cells are predominantly covered by epithelium. (D) Images and segmentations with cell orientation representation for three z-positions and at time point 2. (E) Representative close-up of segmented cells and corresponding nematic order Q score for each z-position Data are meanΒ±s.d. N=3.

YouTube video by Brian Northan Pixi and Napari-Easy-augment-Batch-DL

I just published a new video demonstrating how to use Pixi and Napari-Easy-Augment-Batch-DL for repeatable and reproducible deep learning segmentation. In this example, I use Pixi to set up a Python environment then launch Napari to explore and compare Cellpose3 and Micro-SAM. youtu.be/3ObAnSTBri8

Alternatives to the statistical mass confusion of testing for "no effect." Josh Morgan discusses how progress in cell biology is hindered by significance testing and the need for a shift to effect size estimation. rupress.org/jcb/article/...

interestingly, the group is mainly working with animal tracking data (fish for example) and the analysis highlights collective behaviour ...should work great with cells though
