Analyzing the terrorist's smoking gun

A biological smoke detector developed by researchers at the Lawrence Livermore National Laboratory in California could be used as a standalone device for protecting people in airports, office buildings, rail stations, sporting arenas and other public places from biological weapons attacks. The Autonomous Pathogen Detection System, or APDS, continuously monitors the air explains LLNL chemical engineer John Dzenitis and can detect bacteria, viruses and toxins, such as anthrax, plague, and botulinum.
