He acknowledged that some members of the screening force have had abbreviated training, but said they were operating baggage screening machines and were not screening passengers. He said that eventually, all the members of the screening force will complete the training. The level of training that they ve received in how to run the equipment is adequate for the Norfolk pilot program, Warren said.The manufacturers of the bomb detection machines recommend between two and six hours of training.

Here how she begins: Up in the northern Sierra Nevada, the ecologist Richard Karban is trying to learn an alien language. The sagebrush plants that dot these slopes speak to one another, using words no hu

The evidence for plant communication is only a few decades old, but in that short time it has leapfrogged from electrifying discovery to decisive debunking to resurrection. Two studies published in 1983 demonstrated that willow trees, poplars and sugar maples can warn each other about insect attacks: Intact, undamaged trees near ones that are infested with hungry bugs begin pumping out bug-repelling chemicals to ward off attack. They somehow know what their neighbors are experiencing, and react to it. The mind-bending implication was that brainless trees could send, receive and interpret messages. The first few talking tree papers quickly were shot down as statistically flawed or too artificial, irrelevant to
