Has napari helped your research this year? Why not say thank you to free and open source software by making a small donation? Every bit helps your friendly core team fix bugs and bring new features to life! CZI will match up to $75K in donations! opencollective.com/napari/donate

This looks incredible! Congrats to you and the team! It's great to see the fruit of your labor!

We're a bit late in ringing in the giving season, but it is indeed upon us. Enjoy our special edition holiday logo ☃️ and, if you can spare a bit and appreciate napari, please donate to our development efforts! 🙏 CZI will match donations up to $75K. opencollective.com/napari/donate

New video: more examples showing deep learning segmentation failure modes—and how to detect them with Napari. I show how Napari’s layer system compares images, ground truth, and results, and how Appose enables comparison across incompatible DL packages. www.youtube.com/watch?v=c369...

Happy to finally share micromorph with everyone! If you are interested in performing morphological measurements of bacteria, and like using Python and Napari then this is for you! You can read about it in our preprint, and find the code on our Github repo, PyPi or directly from the napari hub!

Thrilled to see Dr. Kevin Eliceiri and Dr. Beth Cimini awarded an NIGMS R24 grant! 🚀 A major boost for the future of open-source image analysis tools like Fiji, ImageJ & CellProfiler. buff.ly/1LBphLf

Both the deadline and school are coming up, but I still want to boost this among the life sciences crowd! I had the pleasure of teaching one of these schools in Alaska this summer, and it was an AWESOME experience. It's a very inviting space to learn things that we aren't normally taught!

Remember that survey about how we can sustain napari development? We extended the deadline until the 16th, AoE! Blog post: napari.org/island-dispa... Survey: napari.typeform.com/sustainability If you use napari at all we would be super grateful if you filled it in! 🙏

I truly appreciate the organizers, core contributors, and all attendees for this wonderful opportunity! I enjoyed learning and working on napari in a welcoming environment. Those interested in talking about and contributing to napari, let’s join the regular community meeting together!

It was a fantastic opportunity to finally meet the people behind this software that I have been using for years and is so important for my work! A big thank you to all core developers who were so welcoming, and patiently guided participants in their attempts to contribute back to napari!

Happy Halloween from the napari team!

Thrilled to share the first story from my postdoc! 🎉 A wonderful experiment + simulations collaboration. In the Drosophila wing, we find that 3D cell shapes affect signalling range and fine-tune developmental patterning www.biorxiv.org/content/10.1... Thread below ⬇️

Longer wrap-up to come, but in the meantime: we had a fantastic and productive time at the napari hackathon at @globias.bsky.social 2025 conference! Thanks to all the participants and to the GloBIAS team for hosting us!

Episode 17 - perhaps my favorite yet. How do you write a forum.image.sc post that will get you the answers you need without revealing information you don't want to tell? @erinweisbart.bsky.social and I go through what the experts need to know to help you. Post your sci q's today on forum.image.sc !

Do you use napari and love @xarray.bsky.social? Or use Xarray but cry when napari ignores the axis names? Read how we will improve this in the future! 🤝 napari.org/island-dispa... Co-authored by @ianhi.bsky.social and @timmonko.bsky.social, powered by the @scipyconf.bsky.social sprints!

If you ever used napari in your research, take a moment to read this. Napari, like many other resources in the bioimaging world, is freely available despite the fact that it costs many people much time and efforts to develop and maintain it. Now you get a chance to give back, don't miss it :)

Filling out the attached survey and reading this blog will really help bring you up to speed with our progress as a team. Most importantly, we want to guide this project in the direction that sustainably supports the community -- and that's why we'd like your help!

napari 0.6.6 is out! 🚀 This is a bugfix release following up 0.6.5: if something in your napari workflow unexplicably broke, you might want to update ;) Also, with the new bundle you can now "open files with > napari"! Check out the full release notes on the website: napari.org/stable/relea...

Big news! Our week-long #bioimageanalysis bootcamp is BACK! Learn how to think about bioimage analysis like the pros do, learn what corrections you should (and shouldn't!) apply to your images, learn open source tools, and more. Apply NOW at broad.io/BAB3 for our January 2026 course!

This was an absolutely fabulous presentation by @jytinevez.bsky.social, and I highly encourage folks to watch! Grateful that these seminars get uploaded!

Job alert! We are looking for a bioimage analysis to work in an image analysis core facility in beautiful Paris. Can I ask you to share this opportunity with your networks? See also on the forum: forum.image.sc/t/research-e...

Join the new plugin sustainability initiative! Everyone is invited to fill out this interest form: forms.gle/iwX6P4tuooHK... Follow along with initial discussion on Zulip: napari.zulipchat.com#narrow/chann... The first zoom meeting will be this coming week: napari.org/stable/commu...

Halfway to I2K is BACK, friends of all kinds! Last year, 650 people attended 30+ TOTALLY FREE image analysis workshops of all kinds, across many timezones. If you make image analysis software and want to teach it, workshop submissions are open now! We'd love to have your tool highlighted.

napari 0.6.5 is out! 🚀 Rapid-fire highlights are: colorbar overlay, custom startup script, and better and prettier documentation! Check out the full release notes here: napari.org/dev/release/...

Check out the cool new “release highlights history” page @timmonko.bsky.social cooked up for us! 😍 napari.org/stable/relea... Best of all: it’s automatically generated from release notes so it’ll always stay up to date.

@napari.org @jni.codes is a finalist in the @ardc.edu.au Eureka Prize for Excellence in Research Software. Learn more: youtu.be/0g_MkTa_NwQ #EurekaPrizes

It's hard to express how much gratitude I have to everyone involved in the journey, both mine and @napari.org's, that has led to this point. #EurekaPrizes A small attempt below: 👇

🥰 Self-supervised, label-free 3D cell imaging is here Congrats to Cyril on this very cool first, first author publication 🏆! This started when he was a bachelor's student (and he's now completing his masters!). And many thanks to my other awesome co-authors🙏 elifesciences.org/articles/99848

So excited and proud of everyone! 🎉 With this release I worked very hard to contribute to napari and learned so much along the way. I guess they want to keep me around, as I'm a core dev now! 🥳 Grateful for the entire image analysis community. 🥰
