When last year's Nobel prize for chemistry was awarded to the discoverers of green fluorescent protein, the pages of newspapers (this one included) lit up with photographs of "brainbows". Jeff Lichtman, the neurobiologist who created those pictures, had used the discovery to invent a way to tag nerve cells with genes whose products fluoresce green, red and blue. By mixing these three hues in different proportions he was able to "paint" the cells in question in more than a hundred different colours.
