New preprint 🥳! We made photoclickable HaloTag ligands to precisely control protein labeling on living cells. With it, we can do some cool multicolor stuff. Huge congrats to Franzi and all co-authors! Check it out 👇

Mind-bender: The observable universe has ~10^80 atoms. But even a simple 1000×1000 black‑and‑white image has 2^{1,000,000} ≈ 10^{301,030} possibilities — and 24‑bit color explodes to ~10^{7,224,720}. The space of (small) images dwarfs the cosmos. 🔬🧪💻

Hi Fans of Feedback Microscopy,
what would you do when you have access to the pixel stream from @zeiss-microscopy.bsky.social inside @napari.org?
Btw, it works as well in Fiji&ImageJ :-)
Sidenote: Experiments started from "outside" do not update the ZEN UI. But they are executed by ZENservice.

Multiple-Awesome-Colleague Alert! The first is Fred Heberle (not on bsky). His group made a series of 3-component vesicles (high-Tmelt PC-lipid, low-Tmelt PC-lipid and chol) and varied only the high-Tmelt lipid. Then they measured liquid-liquid phase transition temperatures (Tmix) of the membranes 🧵

We wrote a paper about this phenomenon! www.molbiolcell.org/doi/full/10..... On stiff substrates, ventral stress fibers deform the plasma membrane. It’s not that GFP colocalizes to actin fibers, but rather high magnification microscopy is able to observe the variation in membrane/cytosol topography.
