As of now, police dogs are specially trained to find dead bodies by the lovely fragrance of decay. However, this may all change, because scientists are working on a new device that can detect the chemicals that create the smell of rotting corpses. They say they are looking for the "chemical fingerprint of death". Not only will the device help find the bodies, but will also be able to figure out how long the body has been there....just based on the smell. Sounds pretty stinky, but very cool!
"In an advance toward the first portable device for detecting human bodies buried in disasters and at crime scenes, scientists today report early results from a project to establish the chemical fingerprint of death....."
"To develop such a device, scientists must identify what gases are released as bodies decompose under a variety of natural environmental conditions, Jones noted. In addition, they must detail the time sequence in which those odorant chemicals are released in the hours and days after death."
