Sensor Networks for NBC Threats

Nerdsville writes "Planet Analog have an article describing research into a nationwide sensor network that could provide a real-time early-warning system for chemical, biological and nuclear threats across the US. Researchers plan to use microelectromechanical systems (MEMS) and nanotechnology to create accurate biological and chemical sensors. Linked in an Internet-like peer-to-peer network spanning wireless, wired and satellite links."
