THE INSIDE DOPE   Often, things can be improved by a little 'contamination.' Steel, for example is iron with a bit of carbon mixed in. To produce...
A certain sequence of letters, EBU, creates chemical conditions in which an iron atom disconnects itself from an organic molecule (on the right), activating it and causing it to emit green fluorescent light. The sequence EUB leads to the emission of blue light. Other sequences of letters do not cause light emission
