9:00 PM—Discovery

    When a 10-year-old boy gets a first class degree in mathematics or an 8-year-old boy plays chess like a future grand master, they are considered as geniuses. Where does the quality of genius come from? Is it all in the genes or can any child be turned into a genius? And if parents do have a child who might become a genius in the future, what should they do? In this 30-minute film, Barry Johnson, the professor at School of Medicine, New York University will help you discover the answer.

    Is it possible to beat high blood pressure without drugs? The answer is “yes”, according to the researchers at Johns Hopkins and three other medical centers. After a study of 800 persons with high blood pressure, they found that after 6 months, those devoted to weight loss, exercise and eating a low-salt, low-fat food lost about 13 pounds and became fitter. Plus, 35% of them dropped into the “normal” category(范畴). This week, Dr. Alan Duckworth will tell you how these people reduce their blood pressure to a level similar to what's achieved with Hypertension(高血压) drugs.

    The meaning of silence varies among cultural groups. Silences may be thoughtful, or they may be empty when a person has nothing to say. A silence in a conversation may also show stubbornness, uneasiness, or worry. Silence may be viewed by some cultural groups as extremely uncomfortable; therefore attempts may be made to fill every gap (间隙) with conversation. Persons in other cultural groups value silence and view it as necessary for understanding a person's needs.

    Many Native Americans value silence and feel it is a basic part of communicating among people, just as some traditional Chinese and Thai persons do. Therefore, when a person from one of these cultures is speaking and suddenly stops, what maybe implied (暗示) is that the person wants the listener to consider what has been said before continuing. In these cultures, silence is a call for reflection.

    Other cultures may use silence in other ways, particularly when dealing with conflicts (冲突) among people or in relationships of people with different amounts of power. For example, Russian, French, and Spanish persons may use silence to show agreement between parties about the topic under discussion. However, Mexicans may use silence when instructions arc given by a person in authority rather than be rude to that person by arguing with him or her. In still another use, persons in Asian cultures may view silence as a sign of respect, particularly to an elder or a person in authority.

    Nurses and other care-givers need to be aware of the possible meanings of silence when they come across the personal anxiety their patients may be experiencing. Nurses should recognize their own personal and cultural construction of silence so that a patient's silence is not interrupted too early or allowed to go on unnecessarily. A nurse who understands the healing (治愈) value of silence can use this understanding to help in the care of patients from their own and from other cultures.

    Stephen Hawking was born in Oxford, England on 8th January, 1942. He went to school in St Allbans, a small city near London. Although he did well, he was never top of his class.

    After leaving school. Hawking went first to Oxford University where he studied physics and then went to Cambridge University where he studied cosmology(宇宙学）. As he himself admits, he didn't work hard. He was a very lazy student, and did very little work. However, he still got high marks.

    It was at the age of 20 that Hawking first noticed something was wrong with him. He started to bump into things. When he visited his family at Christmas time, his mother was so worried that she made him see a doctor. Hawking was sent to hospital for tests. Finally, the result came back. Hawking had motor neuron disease (运动神经元病）, an incurable illness which would make him unable to speak, breathe or move without the help of a machine. Doctors said they had no way to help him. He would die before 23.

    At first, Hawking became very depressed. After a while, though, he began to see his life in a different way. As he later wrote, "Before my illness was diagnosed(诊断), I had been very bored with life. There had not seemed to be anything worth doing. But shortly after I came out of hospital, I suddenly realised that there were a lot of worthwhile (值得做的）things I could do." Then Hawking got married and found a job at Cambridge University as a professor, He strongly believes that his story shows that nobody, how bad their situation is, should lose hope. "Life is not fair." He once said. "You just have to do the best you can in your own situation."

    Have you ever heard of agritourism where you can experience farm life? If not, Dr. Cindy Ayers-Elliott will tell you the real story of Foot Print Farms.

    The original concept of building Foot Print Farms was simple. When Ayers-Elliott returned to her hometown after graduation, she didn't have to look any further than her state's alarming health statistics to find a mission. Everywhere she turned, there were reports of high blood pressure, diabetes, obesity and heart disease. "The problem was already identified." explains Ayers-Elliott. "Too many Mississippians were seriously unhealthy and it didn't take research to see that. And many of the state's greatest health challenges could directly result from poor diet. "

    These days, Foot Print Farms, which started with a few raised beds of herbs and vegetables, is making fresh, naturally grown food. "When speaking of the key to my success, the co-op model works because we share the work and rewards," notes Ayers-Elliott. "A perfect example is the Wingfield High School football team. To earn the money for equipment and other items, players committed to working five hours a week on the farm, and by the end of the summer they had produced 1, 000 melons and the profits from their sales helped to buy weights, T-shirts, sweat suits and pregame meals. But the lessons they learned about the rewards of hard work and working together to accomplish something were even more valuable products of their efforts."

    "It' s a model that can easily be learned in other places and I' m looking forward to seeing some of our current partners do just that——to take what they have learned here and spin it off in other communities," Ayers-Elliott remarks. She is now looking forward to developing an agritourism aspect to the farm, where visitors can experience farm life, learn new skills and take with them seeds of inspiration they can sow in their own communities when they return home.

    Dogs are our best friends. That's especially true after a disaster, such as an earthquake. When buildings fall down, search and rescue dogs help find trapped people. Dogs' amazing noses can pick up the smell of survivors. Now scientists have developed an electronic tool that does the same thing. It's taking smell detection(探测) to a whole new level.

    The new invention is a sort of electronic nose, which can detect extremely low levels of many compounds(化合物) from people's skin. This isn't the first time engineers have developed such an object. Earlier models, however, have been bulky and expensive. They could not detect low levels of target compounds either. The new one is inexpensive and small enough to fit inside hand-held equipment.

    The electronic nose can detect extremely slight smell of more than one compound at the same time. "Being able to do this, in such a small object, is the significant discovery," says Sotiris E. Pratsinis, Professor of Process Engineering&Materials Science at the Swiss Federal Institute of Technology in Zurich. His team tested it in special spaces. They were like the small spaces where people might be trapped. Chemicals given off by the volunteers built up inside. The electronic equipment detected those compounds at unbelievably low levels.

The results were good news for the research team. But they may be not for our four-legged friends, who could soon be out of a job. "Ideally, this technology could replace search and rescue dogs," Pratsinis says.

    Stephen Taylor, an electrical engineer, agrees that the new technology has some benefits over dogs. Still, he thinks it may be too soon to have our trusty friends retire. He suspects, "I foresee that such an object could add to the fine work done by the dogs." Taylor also pointed out some potential limitations of the new invention. "E-noses are useful, but can be very likely to be affected by unstable readings and interruption," he says.

Do you know that junk food isn't healthy? Of course you do! Do you eat it anyway? Of course you do! But a new study shows teaching adolescents about the ways food companies fool them into thinking junk food is cool can encourage kids to fight back—by eating healthier.

The pull of junk food can be super-strong. It's designed to be tasty, which makes eating well one of the great health challenges of our time. Everyone from doctors to the government has been trying to handle it. Yet we keep eating junk food.

Professor Christopher Bryan says, "Food companies want you to want junk food." They spend millions of dollars coming up with new ways to promote junk food consumption. They hire scientists to make new junk food almost irresistible. They might do this, for example, by adding more sugar. Rats fed junk food for six weeks will even walk across a floor that gives them electric shocks just to get more of such food.

Food ads often make unhealthy junk food seem healthy by featuring professional athletes, fit-looking pop stars and smiling, active teens. "We thought when the students learned this, it would matter to them," Bryan says. He worked with 8th graders at a Texas school. Half of them got a lesson Bryan created. It focused on the ways junk food is advertised, or marketed. A second group received lessons that focused on health. These lessons informed students junk food is bad, and that foods like apples or carrots are a better choice. The students learned a bad diet can lead to major weight gain, and that being overweight puts people at risk for serious diseases. They also learned how eating well now can keep you healthy when you're older.

After the lessons, the kids in both groups were asked how they felt about junk food. Most didn't have positive feelings about these unhealthy foods.
