Electron kaleidoscope: New technique visualizes multiple objects in many colors

Electron microscopy (EM) has long been a leading technology for revealing the shape and structure of the tiniest objects, from the cells which make up the bodies organs and microbes to individual building blocks or molecules which comprise cells, in often dramatic three-dimensional detail. But current EM techniques are limited in that they produce images only in grayscale, with colorization added later. Now scientists describe a new form of multicolor EM that allows for simultaneous visualization of multiple molecular species.
