　　 A nine-year-old schoolgirl single-handedly cooks up a science-fair experiment that ends up debunking（揭穿．．．的真相）a widely practiced medical treatment. Emily Rosa’s target was a practice known as therapeutic（治疗）touch (TT for short), whose advocates manipulate patients’ "energy field" to make them feel better and even, say some, to cure them of various ills. Yet Emily’s test shows that these energy fields can’t be detected, even by trained TT practitioners（行医者）. Obviously mindful of the publicity value of the situation, Journal editor George Lundberg appeared on TV to declare, "Age doesn’t matter. It’s good science that matters, and this is good science."
　　 Emily’s mother Linda Rosa, a registered nurse, has been campaigning against TT for nearly a decade. Linda first thought about TT in the late ’80s, when she learned it was on the approved list for continuing nursing education in Colorado. Its 100,000 trained practitioners (48,000 in the U.S.) don’t even touch their patients. Instead, they waved their hands a few inches from the patient’s body, pushing energy fields around until they’re in "balance." TT advocates say these manipulations can help heal wounds, relieve pain and reduce fever. The claims are taken seriously enough that TT therapists are frequently hired by leading hospitals, at up to $70 an hour, the smooth patients’ energy, sometimes during surgery.
　　Yet Rosa could not find any evidence that it works. To provide such proof, TT therapists would have to sit down for independent testing-something they haven’t been eager to do, even though James Randi has offered more than $1 million to anyone who can demonstrate the existence of a human energy field. (He’s had one taker so far. She failed.) A skeptic might conclude that TT practitioners are afraid to lay their beliefs on the line. But who could turn down an innocent fourth-grader? Says Emily: "I think they didn’t take me very seriously because I’m a kid."
　　The experiment was straightforward: 21 TT therapists stuck their hands, palms
　　up, through a screen. Emily held her own hand over one of theirs-left or right-and the practitioners had to say which hand it was. When the results were recorded, they’d done no better than they would have by simply guessing. if there was an energy field, they couldn’t feel it.

　　 What might driving on an automated highway be like? The answer depends on what kind of system is ultimately adopted. Two distinct types are on the drawing board. The first is a special-purpose lane system, in which certain lanes are reserved for automated vehicles. The second is a mixed traffic system: fully automated vehicles would share the road with partially automated or manually driven cars. A special-purpose land system would require more extensive physical modifications to existing highways, but it promises the greatest gains in freeway（高速公路）capacity.
　　 Under either scheme, the driver would specify the desired destination, furnishing this information to a computer in the car at the beginning of the trip or perhaps just
