China’s Tianhe-1 has a computing speed of 2,507 trillion（万亿）calculations a second, making it the fastest computer in the world. It is also 40 percent faster than the world’s second fastest supercomputer, Cray XT5 Jaguar, in the US, kept at a national laboratory in Tennessee, according to the New York Times. Jack Dongarra, a University of Tennessee computer scientist, told NYT that the Chinese supercomputer is faster than the existing Number One machine.
Building the fastest supercomputer has become a source of national pride, as these machines are valued for their ability to solve problems in areas like defense, energy and science. These problems are related to national interests. Supercomputing technology is also found in business. Oil and gas companies use supercomputers to find oil and gas.
Obviously, research centers with large supercomputers attract top scientific talents. This adds extra importance to the machines—they’re more than just huge computers.
China’s new supercomputer will be used to speed up greatly scientific calculations, such as hurricane and tsunami modeling, cancer research, car design and even studying stars.
In 2008, two US scientists put together a step-by-step guide on how to build a supercomputer using PlayStation 3 video-game consoles（控制台）. Modern supercomputers are built by combining thousands of small computer servers（服务器）and using software to turn them into one large computer. Really, any organization with enough material and technology can create a fast machine.
The Chinese system follows that model by linking thousands upon thousands of computer servers. But the secret behind the system—and the technological achievement—is China’s own networking technology. “That technology was built by them,” Dongarra said. “They are taking supercomputing very seriously and using a lot of time and money.”
“China is still a developing country,” said Sha Chaoqun, manager at Dawning Company which is the leading supercomputer maker in China. “Maybe one day, China’s total computing power can be greater than that of the US, but there is still a long way to go before we get there.”

Kuss Middle School serves students in Fall River, Mass. , a former mill town that has struggled economically for decades. Students at Kuss have struggled, too, usually falling short of making the academic progress required under the No Child Left Behind law.

Then, last year, the school experimented with extending the school day. Teachers got paid at a higher hourly rate.

Students weren't thrilled at first with leaving school at 4:15 p.m. instead of at 2:20 p.m. But the added hours gave them more time for physical education and let them select special interest classes. By the end of the year, student scores had risen by enough to enable Kuss to make the progress required under the federal No Child Left Behind law.

The only surprise is that more districts haven't lengthened school schedules set decades ago to accommodate (适应) a farm economy rather the information economy of today.

New research suggests the time is ready for a change:

Matched against 39 other developed countries, the United States is near the bottom in the rankings of average weekly instructional time in school.  Measured over 12 years, students in the top-scoring countries spend the equivalent of a full extra year in school.

US students perform poorly on math and science tests compared to their international peers, according to a US Education Department comparison released earlier this month. In math, American 15-year-old scored near the bottom among the study's 30 developed countries.

Most countries that boost the number of minutes spent on math instruction find pay offs in improved math scores, according to a study released this month by the Brookings Institution. Small in creases in the school day are more effective than a longer school year, the report concluded.

The most encouraging news about the benefits of extending the school day comes from Massachusetts, where an experiment with 10 schools, including Kuss, appears to be working. Those 10 schools lengthened their instructional days by 25% and boosted their state scores in math, English and science at all grades.

Perhaps the concept won't work everywhere. Certainly, it won't instantly be popular. But it's obvious that a problem exists or that adding class time seems to help.

SHANGHAI - Health experts in Shanghai are calling for more protection for young children as the latest research shows about half of the youngsters are suffering from secondhand smoke.

About 45 percent of children suffer passive smoking in families, 50 percent in public places, and almost 6 percent on public transportation, shows a research released by the Shanghai Children's Medical Center on Tuesday.

"Not only adults but also children and newborn babies are at risk for the adverse effects of passive smoking," said Tang Jingyan, a doctor at the Shanghai Children's Medical Center.

"Actually, those young children whose bodies are still growing and developing are more sensitive to the effects of secondhand smoke."

Research has shown that children who are exposed to secondhand smoke will suffer from more colds, coughs and sore throats, and they are more likely to suffer from bronchitis, pneumonia and will have a higher risk of developing cancer.

Doctors even suggested that children suffering passive smoking are more likely to have behavioral problems and may not develop mentally as quickly as their peers.

Other research by the Shanghai Children's Medical Center has found that more than 80 percent of child patients in the center live in a smoke-filled household, where one or both parents smoke.

"Though doctors have stressed the harm of passive smoking over and over, it is still hard to reach a totally 'smoke free' home," said a pediatrician named Zhang Yiwen, noting that parents are often tempted to smoke even though they have learned the harmful effects of secondhand smoke.

China has 540 million people suffering from passive smoke, 180 million of them younger than 15. The age of smokers is also getting lower, earlier reports said.

"There are more young smokers than before. You can see young people wearing a school uniform and carrying a schoolbag light a cigarette on the street. Some of them are even female students," said Jing Xingming, a professor of children's developmental behavior at the center.

"Children like to imitate adults, especially their parents. If parents often smoke at home, it is very likely children will develop a smoking habit, which can cause a vicious circle," Jin said.

Reports from the Ministry of Health said China has about 350 million smokers, of whom 15 million are underage smokers. Also, around 40 million of the country's 130 million children aged between 13 and 18 had tried smoking, and 15 million had become addicted to tobacco.
