📌 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. [PDF] celltrackingchallenge.net #CellTracking #Python #KalmanFilter #OpticalFlow #OpenScience
🚀 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. arxiv.org/abs/2506.02783 #AI #Bioimaging #ImageJ #OpenSource

Endinsa’t en una vivència sensorial única que connecta ciència i art immersiu. “SEEING: Un ull i una caixa” arriba del 5 al 14 de juny al Centre Cívic Convent de Sant Agustí (Carrer del Comerç 36, Barcelona). www.crg.eu/en/event/see...
Diving “Google earth mode 🌍” in a Shigella infected cell 🔬🔎 Together with @m-albert.bsky.social
Institut Pasteur | 130 years of biomedical research@pasteur.fr · last yr.Zoom into a human cell infected by Shigella, the bacteria behind dysentery. Using cryo-EM, @leaswistak.bsky.social and team revealed how it pierces cells with molecular syringes. Stunning science at the nanoscale. @enningalab.bsky.social @jytinevez.bsky.social @nanoimaging.bsky.social #CryoEM
🚨Paper alert! 🚀 We presented SINETRA at #ISBI2025 in Houston A new simulator for generating realistic 2D/3D neuron tracking data in moving animals like Hydra vulgaris 🧠 Helps test and improve tracking algorithms under tough conditions 📄 dx.doi.org/10.1109/ISBI... #celltracking #syntheticdata #ISBI

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.📊🔬 Check it out:😊 www.nature.com/articles/s41... #statistics #immunology #oncology
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 🧪
Brandy A Freitas@brandy-syglass.bsky.social · last yr.Happy #3DThursday! Today we'll explore a SUB(!!)-volume of 500GB from a cleared, intact mouse brain from Jose Maldonado at Vanderbilt. You can see how we render these enormous data on consumer grade GPUs. 🥽💻 🔎 @josemald.bsky.social, @vucellimaging.bsky.social 🔬 lifecanvastech.com 🥽 syglass.io
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. 🌿 🌲 🌳 👇performance on unseen tropical data

🧪🛰️ 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) earthobservatory.nasa.gov/images/15404...
Swirling Skies and Melting Icebergs
The remote South Sandwich Islands can disrupt passing clouds in ways that shed alternating rows of cloud spirals.

Love pretty biology pix! Vote now.🧪
Maik Bischoff@maikbischoff.bsky.social · last yr.1/4 Super excited to take part in my first big microscopy competition. My picture is the one with the Drosophila hydei testis musculature (Invisible Architects, #12). focalplane.biologists.com/2025/03/11/v... All pictures in this list are fantastic, so, please go vote! 😊🔬 #science #microscopy

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... 🧪

Fibronectin induces a transition from amoeboid to a fan morphology and modifies migration in Entamoeba histolytica
Author summary Even though we know increasingly well how cells move in tissues, the question of whether parasites modify their migration as a function of the host tissue environment requires further i...
