I was today years old when I learned that *Drosophila husbandry* was actually a skillset to add to a cell/developmental biology resume. I wonder if I should add Arabidopsis husbandry to mine 😆

Hello hello world. I’m on here now. I am a microscope addict. I do a lot of plankton chronophotography, see below video of vorticella feeding currents. I love the microworld and consider myself an advocate for these tiny creatures, I like to make them visible. Will post more soon

I was asked whether I was going to paint any shiny reflections to Mr blue swimmer crab.

You bet.

The #mesoSPIM community just celebrated 10 years of open-source light-sheet microscopy in Zürich! For #3DThursday, we're honoring Martina Schaettin & Fabian Voigt’s iconic 3D chick embryo dataset — a luminous benchmark for open science and shared discovery.

Hello scientists of Bluesky! Since we're new here, what better way to introduce ourselves than to share our collection of light-sheet #microscopy data, featuring a diverse range of species and tissue types 🐠🐁🦎🔬: vimeo.com/lifecanvastech

Stay tuned for more #bioimaging data drops coming soon!

This image of moss Physcomitrium patens beautifully demonstrates what we mean when we say that this cell type is characterized by oblique cell walls.
You can see that the cell walls between cells are at an angle and not perpendicular to the cell axis.
#microscopymonday #moss #plantcells
Image shows a filament of three elongated moss cells. The cell outline is in cyan, due to the cell wall staining, while the cell interior appears mostly empty apart from the small and numerous ovoid-shaped chloroplasts in magenta.
