Another season of Stranger things is releasing and we have another season of stranger things happening with Hydra @rouxlab.bsky.social #fluorescencefriday #postdoclife

📌 Tracking cell dynamics just got smarter!
We use Bayesian linking algorithms — KOFT and SKT — implemented in our ByoTrack 🐍 Python library.
Kalman filters + optical flow for links & mitosis detection.

🚀 Manual mask annotation slowing you down?
💡 SAMJ is a new ImageJ/Fiji plugin using Segment Anything (SAM) for fast, interactive segmentation — no GPU needed, one-click install, real-time results.
🔬 Perfect for large biomedical images.

Evolution and origins of multicellularity across the tree of life The study of the origins and evolution of multicellularity in different lineages has recently captured the attention of many research groups and is fueling the generation of numerous innovative resea…

Two heads, toroid shape or a mix of both are the creatures that @yamini-ravichan.bsky.social was able to form inducing soft compression in Hydra. GFP-Lifeact in the regenerating tissue of Hydra #fluorescenceMonday #fluorescencemonday #fluorescencefriday #microscopy #hydra

and with the uniform Laplacian we get a quite funny artefact! (most likely due to the straight cut from the midbrain, which has a few very large triangles)

Exciting news! 🎉 We propose Spatiopath, a null-hypothesis framework for cell-cell & cell-tumor interactions that distinguishes statistically significant immune cell associations from random ones.📊🔬

Thank you to the team at @syGlass for highlighting some of our data. If you haven’t tried working with your data in VR space, you really need to see what you are missing. Syglass is a powerful tool for visualizing and analysis. @vubasicsciences.bsky.social #microscopy #lightsheet #science 🧪

Image shows leaf (black) wood (red) separation by PointsToWood on an unseen tropical forest dataset from Cameroon. Even though we only trained on European forest data, the diversity and high quality of our training dataset results in excellent performance in other biomes.

Our new paper and software tool PointsToWood is out! Led by Harry Owen and Targeted at high performance for small branches, PointsToWood performs #deeplearning enabled leaf-wood semantic segmentation of high resolution #TLS point clouds. 🌿 🌲 🌳

My colleague @simoncarn.bsky.social and I were consulted for this note by @avoiland.bsky.social to comment on volcanoes and clouds in the South Atlantic.

A nice place to study aerosol-cloud interactions! (and other things of course)

Genetically altered 'woolly mice' express several mammoth-like traits, including the animal's iconic coat. The cuteness, meanwhile, is a complete coincidence. That and more of the best in @science.org and science in this edition of #ScienceAdviser: www.science.org/content/arti... 🧪
