"I would relish the chance ... to paint on every corner and junction of every town and city, in whopping words, the line "Chemistry Vital OK!?"
--David Giachardi,
chief executive of the U.K.'s Royal Society of Chemistry, in a letter in the Financial Times of 21 September. He was commenting on the mystery artist who spray-painted the molecular structure of guanine on a road near Cambridge University's Cavendish Lab. Police are still investigating the amino- graffiti, which showed up on 15 September.
