　　Theres simple premise behind what Larry Myers does for a living: If you can smell it, you can find it.

　　Myers is the founder of Aubum Universitys Institute for Biological Detection Systems, the main task of which is to chase the ultimate in detection devices - an artificial nose.

　　For now, the subject of their research is little more than a stack of gleaming chips tucked away in a laboratory drawer. But soon, such a tool could be hanging from the belts of police, arsoninvestigators and food - safety inspectors.

　　The technology that they are working in would suggest quite reasonably that, within three to five years, well have some workable sensors ready to use. Such devices might find wide use in places that attract terrorists. Police could detect drugs, bodies and bombs hidden in cars, while food inspectors could easily test food and water for contamination.

　　The implications for revolutionary advances in public safety and the food industry are astonishing. But so, too ,are the possibilities for abuse; Such machines could determine whether a woman is ovulating,without a physical exam - or even her knowledge.
