When a larval zebrafish twitches its tail, the vascular endothelium lights up with a calcium signal, mediated by Piezo1. We used to think mechanosensing in endothelial cells was about sensing blood flow, but at least in this case it's about sensing body motion.

Head-mounted 2-photon miniscope voltage imaging!

Weijian Yang's group at UC Davis sped up 2p scanning by multiplexing to achieve 400-Hz voltage imaging of ~20 neurons, using ASAP4e

These are the first freely moving single-cell voltage recordings as far as I know.

-> Maybe a solution is to paint a circle around the nose with a 'hydrophobic barrier pap pen" (link below). Has anyone tried this?

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 🧵

The FPbase spectra viewer just had it's biggest software refactor in 6 years. It *should* be largely invisible to the end user (hopefully just faster and less buggy). Please let me know if you find any issues as you use it!

I'd only dabbled with napari, but needed to use it for a paper we're writing. This is a quick post about getting started: from installation to a folder full of thousands of processed images, with gotchas along the way.

Get out your calendars! The motors are out of quarantine and we plan to assemble in person on 8th May 2026 at University of Warwick Campus for a fun day on motors and the filaments they walk along. Livestream is planned too. More details on registration, travel bursaries etc. will be revealed soon.

Tracking has always been at the ❤️ of the scientific method, from planetary motion to single particles.

Weiqing’s thesis intro on tracking was so beautiful we turned it into a perspective in JCP who then selected it as a #Scilight.

Take a look! 😊

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.
