Our Cell Scientist to Watch interviews in our Cell Biology of the Nucleus Special Issue are with Kate Miroshnikova @katemiro.bsky.social and Andrew Stephens @andrewdstephens.bsky.social. journals.biologists.com/jcs/issue/13...
We spoke to Kate @katemiro.bsky.social about her ‘random walk’ into cellular biophysics, how AI might uncover links between nuclear morphodynamics and cell fate hiding in plain sight, and fishing for crayfish as a child growing up in Kazakhstan. journals.biologists.com/jcs/article/...
Excellent review of an emerging field in microscopy

Microscopy beautifully reveals the dynamic nature of biology but quantifying that motion can be tricky! In the latest paper from @aicjanelia.bsky.social, out now in @jcellsci.bsky.social, we present a tool for measuring amorphous motion: OpticalFlow3D journals.biologists.com/jcs/article/... (1/7)
OpticalFlow3D – a tool for measuring amorphous motion in three-dimensional fluorescence microscopy images
Summary: Biological motion can be difficult to define and measure. Optical flow is uniquely suited to this challenge. We provide tools for 3D optical flow and illustrate its use in extracting biologic...

📣 Tracking cells through time – including divisions – is a core problem in live-imaging microscopy. We built HOCT, an edge-centric Transformer that hits state-of-the-art on the Cell Tracking Challenge without a pretrained image encoder. Work led by @jookuma.bsky.social arxiv.org/abs/2607.11754 🧪🔬💻

No live nuclear label? No problem. Use artificial labelling to infer DAPI-like nuclei, then use #NucleiSky to align your data. For instance, to connect live imaging data to fixed Cell Painting images.

CD44 restricts EGFR mobility to polarize cytoskeletal signalling modules driving bleb-based migration - Nature Cell Biology
Jha et al. show that the transmembrane protein CD44 restricts EGFR mobility to maintain an EGFR–PI3K–Rac gradient during bleb-based cell migration.

This is one of the nice application of #NucleiSky
Iván Hidalgo-Cenalmor@ivanhcenalmor.bsky.social · last mo.NucleiSky in a smart microscopy pipeline 🧠🔬 A query image is first acquired on Microscope A (widefield). As the video shows 📹 the same sample is then moved to Microscope B (spinning disk), where it is automatically scanned, NucleiSky recognises the same FoV and triggers high-resolution re-imaging.
NucleiSky is easy to install and use! You can install the API with `pip install nucleisky` or you can get started with our user-friendly notebooks, either on Google Colab or by installing them locally with a simple executable ♥️ Thanks #LabConstrictor! Check out our doc 👉 github.com/CellMigratio...
NucleiSky was integrated into a Nikon NIS-Elements JOBS workflow to enable smart microscopy during image acquisition 🧠🔬 Using a Nikon microscope and interested in trying it? The docs explain how to implement the pipeline 👇📝 github.com/CellMigratio...
Nikon Microscope Solutions@healthcare.nikon.com · 6mo ago🧠What if your imaging software could make decisions as it goes? 📝This app note highlights an adaptive feedback microscopy workflow using the Nikon AX confocal system and NIS-Elements with JOBS and GA3 modules to study the lateral line system in juvenile medaka fish. 📄Read: https://bit.ly/4tkzpzM

Annual killifish continue to surprise us: they make neutrophils before almost every other cell type, even before gastrulation. Neutrophils usually arise from the lateral plate mesoderm (forming in cyan), but in killifish they are already patrolling around the embryo in gold. tinyurl.com/killiphil
