A series of spontaneously blinking dyes for super-resolution microscopy - Nature Methods A series of spontaneously blinking dyes in the far-red range facilitate single-molecule localization microscopy. These dyes vary in their blinking properties and can be matched to the applications and...

Out in @natmethods.nature.com: More dyes. They work. Quite well. And blink. Pick the one that fits your target, your technique, and your labeling density. With too many collaborators and institutes to list, but anchored at @hhmijanelia.bsky.social www.nature.com/articles/s41...

We tracked a zebrafish tail tip for 30h of light-sheet imaging.

Cells can sense the geometry of their environment, from tiny subcellular features to whole-tissue patterns. How can we engineer environments to systematically probe these responses?

🧵 I'm @lhinderling.bsky.social from @olivierpertz.bsky.social lab, let’s do a short tour on microfabrication!

We’re excited to announce the opening of the Geneva Expansion Microscopy Facility (GenExM)!

GenExM is a full-service U-ExM platform (U-ExM, Cryo-ExM, iU-ExM), delivering nanoscale imaging.

Led by Dr. Olivier Mercey, GenExM welcomes academic & industrial collaborations.

1/14 “Epithelial” & “Mesenchymal” aren’t binary categories—they form a spectrum, or better yet, a multidimensional space. This becomes especially clear in collective cell migration, which often depends on a finely tuned degree of “mesenchymal-ness”.
