90% of you probably don’t need to read this.
But maybe some of you are curious & 10% will feel seen. Or a little less alone. This isn’t about seeking sympathy.
It’s about sharing something hard to say out loud;
partly to heal, partly in case someone needs to hear it too. (1/3)

New paper out! Here's a puzzle: phototrophy, the ability to use light for energy, is one of life's great innovations. It evolved early and transformed the biosphere. But it evolved 2x. Why not just once, why not more? Our work suggests the answer is priority effects.

I also very much enjoyed being in full handle of the #Zeiss 3Dsim scope provided generously for us to explore the various samples.

Over the last two weeks the Dudin Lab expanded two-fold and it’s been a blast!
We are hosting a group of amazing visitors that stopped by with their own species and samples to get started with expansion microscopy.
It was a ton of fun, very much looking forward to pictures to come ❤️

Are you staining DNA in your ExM samples?
We have awesome news for you! All our 6 SPY-DNA probes work beautifully well with the U-ExM protocol.
You can now tune the color of the DNA channel to your needs, according to the fluorophores on your preferred antibodies.
