Ever wondered if analyzing your images by using intensity Z-projections impacts your data?
Happy to announce my guest article in Microscopy & Analysis on that topic. It's a very short read but worth for everyone dealing with image analysis!

One alternative plant transformation tek I am so excited to try is the carbide whisker method. It uses thin silicon carbide fibers (nano-needles) to poke the crap out of plant tissue. Just adsorb DNA onto whiskers, add plant bits, and vortex for 1min. Obvs do not breathe in dust; respirator a MUST.

I am beyond thrilled (like the screaming and jumping type of thrilled) that my SNSF Starting Grant was funded. I will start my own lab @unibe.ch next year, studying succulent anatomy development and if and how this anatomy is required for efficient CAM photosynthesis in different Kalanchoë species 🌱
