Fantastic to see the Nobel Prize awarded for the discovery of channelrhodopsin which arose from Peter Hegemann's studies of algal motility. Here is a Chlamydomonas cell celebrating with some flagella calcium signals!

Excited to share the lab's 1rst preprint! Rapid high-res immunofluorescence is now possible in cultured & environmental diatoms thanks to 4-fold expansion microscopy. A step-change for comparative cell biology in one of the most important phytoplankton groups on the planet 🥳 tinyurl.com/m9s5su7s 1/2
