I want to thank all of the co-authors, though I can't find any of them are on bluesky. In particular, I want to thank Priyanka Saminathan for all her work getting this to the finish line!

All of the segmentation and morphometric analysis was done with the open-source platform QuPath. The scripts I wrote are on Github and the raw images are on the BioImage Archive, because open-source is the way to go!

But seriously, look at these cells! They are so angry.
Reactive microglia looking particularly angry. Iba1 showing cell shape in magenta, large amounts of CD68 in green, nuclei in blue. The cells are outlined in brown and the nuclei are outlined in cyan. There are lines connecting the nuclear centroids from Delaunay triangulation.

We used widefield slidescanning + deconvolution + Z projection to image microglia in the hippocampus. 2 years in with ~11000 cell analyzed and I'm still not over how pretty microglia can be.

We found signs that glia in female AD mice begin to react to *something* before there are even plaques.

Happy Fluorescence Friday!

Chaotic good! I honestly spent 5 minutes debating whether hdf5 or ome.zarr was more chaotic

Yea, true. But I'm not sure it's more evil than the other 3.

I got this in my head and I couldn't focus on work until it existed.

It's not just #NIH. It's not just #NSF. It's not just #NASA.

The whole scientific community has to make clear that all science across fed agencies is being destroyed in the US.

We can't just ask for our particular piece of the pie. The whole pie is being thrown out - saving your bit won't work.

Every flashbang could instead be a meal for a poor kid. Every hotel room for a National Guardsman deployed to fire at our neighbors could house a homeless vet. Every "less-than-lethal" bullet pulled from a journalist's eye could be already needed healthcare for anyone else. All of this is a choice.

It's not that we might lose our jobs. It's that all of it will disappear or mutate beyond recognition. I worry we're not talking or thinking enough about this deeper sadness hiding behind our immediate anxieties and it's this heaviness that has us all at a breaking point.

Bioimaging and bioimage analysis friends, some help if you have 2-3 mins; for a paper, we're trying to estimate the number of biologists trained in open source software or tools in the last ~5 years. (1/2) #bioimaging #microscopy #bioimageanalysis

WATCH: Elephants at the San Diego Zoo Safari Park react to Monday's 5.2 magnitude earthquake that shook San Diego County. The elephants formed an "alert circle" meant to protect the young and the entire herd from any threats, according to the San Diego Zoo Wildlife Alliance.

Your yearly reminder to acknowledge the core facilities you use and their staff scientists in your papers. These scientists are a crucial part of the scientific ecosystem and to continue to exist they need tangible credit for their work. Plus their associated expertise adds credibility to your work.
