When the “underwear bomber” passed through security last Christmas, no one noticed the three ounces of PETN, one of the most reactive explosives, stuffed in his pants. Now a new portable chemical detector, capable of sensing explosives’ vapor at parts per trillion, could finally uncover this and other chemical threats at airports.
Researchers are now profiling the chemicals released from decaying bodies, in an effort to create a sensor that might be able to sniff out corpses in the rubble, or determine a dearly departed's precise time of death.
Man's best friend? Not if the man is on trial and the dog is an expert "nose witness" who may be more convincing than reliable.

Juries love dog testimony. As witnesses go, nothing beats a
canine for sincerity and trustworthiness, and nothing brings a little light into a dismal courtroom like the goofy grin and thumping tail of a hound.
"The jury eats it up," says police K-9 handler Pat McAlhany, a veteran of the Miami-Dade County Sheriff's Office. "From a prosecutor's standpoint, there's nothing better than my actually bringing my dog into the courtroom for a demonstration."
