In a dimly lit laboratory room in Gottingen, West Germany, Einhard Schierenberg bent his long, angular frame over his microscope, watching and counting, recording what he saw on charts and videotapes, hour upon hour, day after day, intermittently for six years. Five hundred miles away in a tiny, starkly equipped cubbyhole in Cambridge, England, John Sulston was doing the same thing, hunched over his microscope, earphones on his head to block any sound that might divert him from the image in his eyepiece. Sometimes he would sit watching all day long, diligently marking in a notebook with his colored pens. Schierenberg and Sulston were learning, cell by cell, how to build a worm.

Geoffrey Gold, a physiologist at the Monell Chemical Senses Center in Philadelphia, had wanted for years to put to rest a nagging question: How do odors trigger olfactory neurons to fire off action potentials to the brain? The dogma for the past 5 years had been that odors fall into two catagories, each of which acts via a different inracellular messenger molecule. But Gold believed this view was wrong, and that all odors work by increasing the production of the intracellular messenger cyclic AMP (cAMP). One day last spring, Gold got a phone call out of the blue from neurobiologist John Ngai, at the University of California (UC), Berkeley, offering the possibility of answering this question. It was my dream come true," says Gold. ......
