War on terror insects

Annoying as they are, you may want to think twice before you crush a cockroach or swat a flyyou could be killing a future foot soldier in the war on terror. Increasingly, scientists are turning to insects and other creatures for better ways to identify biohazards. Cockroaches can detect all kinds of things, from anthrax spores to DNA, says Karen Kester, an entomologist at Virginia Commonwealth University. With $1 million in funding from the Pentagons Defense Advanced Research Projects Agency (Darpa), Kester is studying ways to use roaches and houseflies as toxin sentinels inside contaminated buildings or subways. This, of course, spares humans the job, and it may prove more effective than mechanical sensors, which often lack the range and sensitivity of their living counterparts.
Bees and fish are also in demand. A small British biotechnology firm called Inscentinel is employing the finely tuned olfactory system of bees to sniff for explosives. And New York, California and Maryland are exploiting the highly sensitive nervous system of bluegill fish to test for toxins in municipal water supplies. Bill Lawler, co-founder of Intelligent Automation Corporation, the California company that sells the bluegill-monitoring system, says living sensors are the wave of the future. So go easy on the Raid.
