Fruitful Dyes

These colorful, computer-generated ribbons show the backbone of a molecule that glows a fluorescent red. The molecule, called mStrawberry, was created by chemists based on a protein found in the ruddy lips of a coral. Scientists use the synthetic molecule and other "fruity" ones like it as a dye to mark and study cell structures. Courtesy of Roger Y.
