💥Beyond happy 💥 Our work is now published in PNAS!
www.pnas.org/doi/10.1073/...
With Gloria Canales & @mazi1.bsky.social we studied how the single celled alga Pyrocystis lunula 🌙 move their chloroplast in response to strong light.
Get ready for some fun mechanics, signals and organelle motion! 🧵

We just released a new major version of TrackMate (v8), the cell and organelle tracking plugin of Fiji.
It ships many new features, detailed below, but that are articulated around the following:

it was already fun to look around the documentation for cmap (cmap-docs.readthedocs.io)
but @grosoane.bsky.social just added a very cool feature to toggle between color vision deficiencies. Watch your perceptually uniform color maps gain some kinks 😂
as a mild deutan myself, I appreciate it! 🙏

Here’s why your blood vessels don’t burst under pressure
Cells lining the blood vessels reorganize their inner structures to handle stressful boosts in pressure.

PSA: around 5-8% of the population has a color vision impairment for red/green.
Many talks at #2025ICDB still use red-green LUTs on slides that are not accessible to everyone.
Changing to more accessible colors is doable and easy.
We can do better.
