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? 🧵

Many sea stars begin life as young fairy-like creature (called a brachiolaria) that float through the open ocean. Eventually, a small star forms within them (here in yellow). The fairy-like brachiolaria sinks under the star’s weight, and the star pops out!
