Sweat Ducts May Act As Antenna For Lie Detection 120
Reservoir Hill writes "Researchers have discovered that human skin may contain millions of tiny "antennas" in the form of microscopic sweat ducts that may reveal a person's physical and emotional state. This discovery might eventually result in lie detectors that operate at a distance. In experiments, the team beamed electromagnetic waves with a frequency range of about 100 gigahertz at the hands of test subjects and measured the frequency of the electromagnetic waves reflecting off the subjects' skin. Initially, the experiments were carried out in contact with the subjects' hands, but even at a distance of 22 cm, researchers found a strong correlation between subjects' blood pressure and pulse rate, and the frequency response of their skin."

As a milder example, human memory isn't photographic, ever.
But really now. I *did* have to dodge sniper fire from angry Chiba farmers who didn't want their land "annexed" into a new runway the first time I flew into Narita.

I used to think slashdot was a site about technology but now days it's just a bunch of paranoid conspiracy theorists worried about stuff that isn't happening, at the same time complaining about the Bush administration's culture of Fear.

Gary Leon Ridgway (AKA green river killer)

Both of them passed a polygraph. With Ames, he passed numerous polygraphs while he was working for the USSR.
Apologists for polygraph testing say that Ames was given big, bad, scary, 'sophisticated countermeasures' by his KGB contacts, but he says that all his KGB guy told him was to get a good night's sleep and try to relax.
