Allow me to introduce myself by way of a homecoming.
It was at Discover that I started writing about science, a couple years out of college and with no clear idea of what I was going to do. My first two articles came out in the same issue in November 1989. One was illustrated with a picture of E. coli colonies, each glowing its own color of the rainbow. The story described the work of a scientist named Keith Wood, who had isolated the gene fireflies use to glow in 1984, and who went on two isolate genes for other colors from Jamaican beetles.
