Interesting Fact:

Engineers are actively developing tools to provide the earliest possible warning of biological and chemical threats and assaults on critical equipment and infrastructure. From "labs on a computer chip" that look for thousands of molecules at a time to sensors that detect faulty wiring in airplanes, engineers are crafting devices that address a wide range of early warning needs.
