The International Day for Women and Girls in Science is coming up this week on Wednesday February 11th! 🧫 🔬 To celebrate we created a new colouring page! 🧪✍️🎨 Please share this post with any educators or teachers you know! www.thebraincolouringbook.com/printables

New Journal Club: Neural manifolds are maturing from visualization trick to biological claim. But if population activity lives on low-dimensional manifolds, what constrains the geometry?

Falling in love with #marimo. Scattering of roots of perturbed quadratic equations. Made with #python #numpy #matplotlib and @marimo.io Notebook and code in the first comment 👇👇👇

I'm excited to share jaxion, a differentiable Python/JAX library for fuzzy dark matter (axions) + gas + stars, scalable on multiple GPUs ⭐️repo: github.com/JaxionProjec... 📚docs: jaxion.readthedocs.io Feedback + collaborations welcome!

I noticed Google search is no longer reliable for quick unit conversions & calculations. So I built a simple online calculator Give it a spin: pmocz.github.io/online-unit-...

Your body runs on electricity, not just your brain ⚡ New Nature research shows skin and organ-lining cells use bioelectric signals to eject weak neighbors. Crowding stresses cells electrically; those that can’t keep up shrink and get expelled. Electricity = cellular quality control.

The brain is more than spiking neurons. Astrocytes, a large fraction of cells, propagate electrical influences without spiking. And cortical neurons spike only intermittently. Electrical signals are continuous and across all cells. #neuroscience www.quantamagazine.org/once-thought...

Why don’t neural networks learn all at once, but instead progress from simple to complex solutions? And what does “simple” even mean across different neural network architectures? Sharing our new paper @iclr_conf led by Yedi Zhang with Peter Latham arxiv.org/abs/2512.20607

Today I'd like to honor the memory of my mentor and friend, Roger Tsien, born 1952 February 1. Today would have been Roger's 74th birthday. Most know Roger for his 2008 Chemistry Nobel Prize with Shimomura and Chalfie. Roger made GFP into the versatile imaging method it is now.

Postdoc position in systems neuroscience! Excited to recruit a postdoc for my lab at the University of Bonn. 🔬 In vivo physiology (Neuropixels, 2P/miniscope) 🐭 Head-fixed & freely moving behaviour 💡 Optogenetics/chemogenetics ⏳ Start: ASAP | Application deadline: 28.02.2026 More info below ⬇️

Cell death isn’t failure...it’s biology doing its job. This video shows programmed cell death, a regulated process that shapes development, removes damaged cells, and keeps tissues healthy. Too little leads to cancer. Too much drives degeneration. Life depends on knowing when to let go. 🧬

This poses an intriguing question: how is cytoplasm robustly and accurately organized in absence of physical barriers, and how is cytoplasmic partitioning achieved within the constrained time window of rapid embryonic divisions? (2/9)

Really excited to share our new paper in @nature.com! We uncovered how a physical instability of the cytoplasm coupled with the cell cycle drives cytoplasmic partitioning in early embryos #zebrafish #drosophila. Read more in this🧵 www.nature.com/articles/s41... 🤩 @poldresden.bsky.social @mpi-cbg.de

A 16-hour time-lapse of neurulation, the process that forms the neural tube, precursor to the brain and spinal cord. Coordinated cell folding, cytoskeletal forces, and SHH/BMP/Wnt signaling build the nervous system’s central axis in under a day. 🧠🧬

Latest work from the lab by Aude Nommick et al., in which we propose a "size-scaling" model for microtubule force exertion that regulates centrosome centration vs decentration during embryo development! @ijmonod.bsky.social www.biorxiv.org/content/10.6...

#ArXiv is cracking down on #AI #slop and will only allow initial submissions based on recommendations from established ArXiv authors. 🌍 https://www.science.org/content/article/arxiv-preprint-server-clamps-down-ai-slop#ArXiv#AI#slop#preprint #AIslop

What's the relation between voltage and calcium in dendrites? Xiang Wu studied this in CA2 hippocampal pyramidal cells in behaving mice. www.biorxiv.org/content/10.6...

I studied at the #UniversityOfCologne and Susanne Crewell was one of my professors. Nice to see my #AlmaMater highlighting her work on such a relevant #climate topic! #unicologne #cologne #climatechange #meteorology

Excited to share our new preprint! We explore the link between the locus coeruleus (LC) and arousal for astrocytes, pyramidal cells, interneurons in the hippocampus. A fantastic collaboration with @sianduss.bsky.social @bohaceklab.bsky.social, and many others: www.biorxiv.org/content/10.6... 1/5

Talk on "High-dimensional neuronal activity from low-dimensional latent dynamics" at NeurIPS 2025 with @haydari.bsky.social now accessible online 🎥: neurips.cc/virtual/2025... Please reach out if you have any comments or ideas for follow-up work!

Why size matters in brain simulations: Larger networks reveal properties smaller models miss. With exascale supercomputers like JUPITER, we’re testing theories of memory, epilepsy, and more! @newscientist.com interviews Markus Diesmann, Johanna Senk and Thomas Nowotny go.fzj.de/newscientist...

We are excited to share our paper on the DendroTweaks toolbox is now published: doi.org/10.7554/eLif.... DendroTweaks offers a rich set of tools for working with neuronal morphologies, ion channels, and synaptic inputs. It is available as both a standalone Python package and a web-based application.

I didn't even realize how long I had been waiting for a tool like this!

Several #CompNeuro PhD positions open at the University of Göttingen! 👇

Striking how clearly sudden qualitative change is already formalized here. Anticipating much of what later became #TippingPoint theory. #CatastropheTheory #DynamicalSystems #Topology #ComplexSystems

Interesting read on how chunking can emerge directly from #synaptic dynamics: by temporarily suppressing groups of items via synaptic augmentation, #WorkingMemory can retrieve up to 8 items despite a base capacity of only 4.

New preprint out! 📣 Great collaboration w/ @martonkarsai.bsky.social and @alainbarrat.bsky.social! How do adaptive behaviors, triggered by risk perception, affect higher-order contagion processes? What happens to the contagion dynamics and to the phase transition? arxiv.org/abs/2601.05801 🧵1/7

🚨This was not supposed to be a Friday news dump. Come join us at the pre-COSYNE hackathon! And if can’t make it to the hackathon, don’t overthink it. Start working on the full CON2PHYS project: mchini.github.io/con2phys/ Remember that submissions will be eligible for co-authorship!

I can’t help but think that the morphodynamic patterns in this video strongly remind me of an #MHD #plasma simulation: continuous flows, deformations along implicit fields, and structures that arise from dynamics rather than static forms. … However, I am biased. #SpacePhysics #Magnetohydrodynamics

Please spread the word🔊My lab is looking to hire two international postdocs. If you want to do comp neuro, combine machine learning and awesome math to understand neural circuit activity, then come work with us! Bonn is such a cool place for neuroscience now, you don't want to miss out.

Excited to be giving the van Vreeswijk Theoretical Neuroscience Seminar this Wednesday, Jan 14, where I'll talk about "Computation Through Neuronal-Synaptic Dynamics"! www.wwtns.online
