...stress that creates the clues picked up by polygraphs also boosts blood flow in capillaries around the eye. A new application of thermal-imaging technology, called periorbital thermography, uses a high-resolution camera to detect temperature changes as small as .045°F (.025°C). Endocrinologist James Levine of the Mayo Clinic in Rochester, Minn., co-authored a paper in the journal Nature in 2002 in which he claimed a lie-detection accuracy of 73%. Investigators at the Department of Defense Polygraph Institute (DODPI) in Fort Jackson, S.C., tell TIME they have reached...
...improved lie detection is likely to have broad public support. But what about when it reaches more surreptitiously into our lives? Biophysicist Britton Chance of the University of Pennsylvania has explored ways to use infrared light projected from a distance to penetrate the skull, looking for signs of stress similar to the ones fMRIs detect. Both that and remote periorbital thermography could be used undetectably in airport lines to spot high-stress passengers. Whether that stress is caused by the bomb you're concealing or the fact you're running late can't be known until you're pulled from...
...always reserved special venom for groups they label xie jiao, or evil cults. The most famous is the brutally suppressed Falun Gong movement, but the authorities may be tempted to extend that label to the Christian sects that are growing the fastest--those practicing fervid forms of worship that stress miracles and personal inspiration through prayer. A number of cultlike, pseudo-Christian offshoots have sprung up in the Chinese countryside in recent years, apparently inspired by this ecstatic form of worship. Often spawned by the personal ambition of their leaders, these highly secretive groups usually espouse millenarian views that make...
...Clark added that the agency could not supply the demographic makeup of some 43,000 TSA screeners on duty today. The reason to replace ID checkers would be "using human technology, if you will," says Clark, "to search for behavioral stress levels." New TSA ID screeners, she says, would receive psychological training on how to question passengers, akin to how Israel's El Al airline operates. (Chertoff also said this week that current TSA screeners will receive 38 hours of training in the detection of "detonators and modern types of explosives...
...says. "It may be that there is insufficient absorption to select for resistance. But we won't know that answer until we do the efficacy trials." The first of these results, from Nigeria, will be released in September 2007. Even if they prove to be effective, Ramjee and others stress that microbicides - whether they come in the form of a gel or cream applied before intercourse, or as part of a delayed release ring inserted into the cervix that can provide the drug for anywhere from 30 to 90 days - are not a physical barrier to HIV. At best, microbicides...
