Exciting news to start the new year! We’re thrilled to see this work finally out in @natecoevo.nature.com, the result of a major collaboration between my lab and the labs of Veronica Hinman and Nacho Maeso, began many years ago with the dear José Luis Gómez-Skarmeta.

How can we see the cells that make up a living organism? Membrane-localising tags can drive fluorescent proteins to the cell's outer membrane, making their outlines visible. But the tags don't work well in all organisms. How do you find one for your species of interest? 🧵
