The people who listened to music needed fewer doses and had a 36 percent reduction in the intensity or the amount of medication they received. In addition, their anxiety decreased by about 36 percent. Both doctors had similar explanations for why music was so successful.

　　"Music operates on many levels. It can be a very powerful distractor in the brain, where we're listening to something that is pleasing and then it interrupts stressful thoughts."

　　"Music can be a distraction. And if you're doing something you enjoy, time seems to go by faster."

　　These doctors seem to agree with a line from the old Bob Marley song, "Trenchtown Rock." It says "one good thing about music, when it hits you, you feel no pain."

　　"Walking with Dinosaurs" Blends Entertainment, Science

　　Twentieth Century Fox 'Walking with Dinosaurs'
The film called "Walking with Dinosaurs" is a story that mixes entertainment with science. The actors who performed the voices of the characters say they found themselves learning more about the ancient creatures as they made the movie. Jim Tedder reports.

　　The 3-D film is set in Alaska during the late Cretaceous Period, 70 million years ago. A media event at the Natural History Museum of Los Angeles had an actor in a dinosaur costume and three of the film's stars, including John Leguizamo. He stood beside the oversized dinosaur.

　　"You're not scared?"

　　Leguizamo says the movie was well researched. The settings were partly filmed in Alaska and the computer-generated dinosaurs include a plant-eating species called Pachyrhinosaurus.

　　The film follows a herd of Pachyrhinosaurs, creatures with large bony skulls, and a young member of the tribe named Patchi.

　　Leguizamo is the voice of a smaller creature, named Alex.

　　In the film, he congratulates a pachyrhinosaur couple on their newly hatched baby.

　　"Well, look what we have here? Allow me to congratulate you on this happiest of occasions."

　　Tiya Sircar voices a female pachyrhinosaur. She says the science behind the film interested her.

　　"I actually, for a lot of my elementary school years, thought that I would be an archeologist or a paleontologist when I grew up. That did not happen, as of yet. I mean, who knows."

　　Skyler Stone, the voice behind a character named Scowler, also learned something while making the movie.

　　"There were dinosaurs I'd never heard of. I was like ‘wait a minute.' They were like, ‘Yeah, we just discovered these ones.' I said, ‘What? This is crazy?'"

　　"Walking with Dinosaurs" is based on a popular science series on the BBC. Some critics say the TV series was better than the film. But Luis Chiappe disagrees. He heads the Natural History Museum's Dinosaur Institute and advised the filmmakers. He says films like this one get kids involved in science.

　　"They stimulate them to come to a place like this, the natural history museum, to see the real thing. So they're fun, they're educational, and they're inspirational."

　　And he likes the story.
