should you ever find yourself in George Preti's lab: Don't inhale. From the doorway, his windowless lair at the Monell Chemical Senses Center in Philadelphia looks harmless, with its wonky assemblage of test tubes, beakers, reagents, rubber gloves, and laminar-flow hoods. Then Preti guides you to a bench under one of the hoods. He unscrews a cap from a bottle of clear liquid and waves the vessel under your nose. When your reaction falls short of nausea, he tries another bottle, the fumes from which will ruin your appetite for hours. Preti grins and turns the bottle so that its label faces you. The label says pseudo arm pit.
