BEIJING, Feb. 8 (Xinhuanet) -- China's railroads and highways will see their busiest day of the Spring Festival holiday on Tuesday when the number of travelers returning to major cities hits its peak, just as a cold snap sweeps across much of the country, the ministries of railways and transport said on Monday.The Ministry of Railways said on its website that there had been a sharp rise in the number of travelers leaving smaller cities on Monday bound for such places as Beijing, Shanghai and Guangzhou.The ministry said the number of people on the move on Tuesday is likely to make the day the Spring Festival travel peak.The nation's roads are also likely to be at their Spring Festival maximum on Tuesday and Wednesday, the Ministry of Transport reported on Monday on its official website.The National Meteorological Center (NMC) added on Monday that a moderate cold snap was expected on Tuesday, causing temperatures to fall by between four and six degrees in most parts of China.The weather pattern will bring widespread rain and snow to the southern part of China from Wednesday to Friday, the NMC said.The Ministry of Railways said on its website that it has asked its local branches to be prepared for the upcoming icy weather.Meanwhile, the local authorities in big cities have been bracing for the arrival of massive numbers of travelers as the Spring Festival holiday winds down.In Shanghai, tens of thousands of public transportation workers cut their holidays short and put 27 additional bus lines on the road to meet demand as passengers began arriving in large numbers at the city's railway stations.The influx began on Saturday night, according to local newspaper Wenhui Daily.On Sunday, the pressure intensified on the Qinghai-Tibet railway, two days earlier than expected.As a result, the railway company organized additional workers to facilitate the flow of people through Xining Railway Station in Northwest China's Qinghai province.Many volunteers have also been pitching in to help keep people moving and have offered to do various jobs at stations, such as helping people buy tickets and assisting them in checking their travel schedules.Among them, Liu Chen, a student from the Guangzhou-based Zhongkai University of Agriculture and Engineering, has been helping people at Guangzhou Railway Station by carrying their bags."One day, I helped more than 70 passengers with their luggage and, after all of them got on the trains, it felt like my legs were almost paralyzed," he said.The Hohhot railway bureau in North China's Inner Mongolia autonomous region said it is expecting so many extra passengers that it has scheduled four additional trains for lines to Chongqing and Beijing.With so many people scrambling to get back from family gatherings and holidays to their jobs in China's big cities, the rush to buy tickets has been phenomenal. Tickets for trains that will leave Nanjing on Tuesday for Beijing, Guangzhou, Harbin and Changchun had virtually all gone on Monday morning, Jiangsu's Yangtse Evening Post reported.On Sunday, the fourth day of Spring Festival, the country's railways carried a total of 5.3 million travelers, which was up by 12.8 percent on the 4.7 million who rode the rails a day earlier, according to the Ministry of Railways.Another 38.6 million travelers made Spring Festival trips on Sunday on buses and ships, according to the Ministry of Transport.The traditional chunyun period, or Spring Festival travel season, runs for 40 days and is calculated in two phases: 15 days before Spring Festival Eve and 25 days after it, as stipulated by the central government.China's railways moved about 77.3 million passengers during the first 15-day period, which ran from Jan 19 to Feb 2, the Ministry of Railways reported.

LOS ANGELES, April 14 (Xinhua) -- Vegetarians experience a much lower risk of metabolic syndrome than non-vegetarians, U.S. researchers have found.Researchers at Loma Linda University in California based their findings on analysis of more than 700 adults randomly sampled from a long-term study of the lifestyle and health of almost 100,000 Seventh-day Adventist Christians across the United States and Canada.While 25 percent of vegetarians had metabolic syndrome, the number significantly rises to 37 percent for semi-vegetarians and 39 percent for non-vegetarians, according to the study published in the April issue of the journal Diabetes Care.The findings showed that the risk of developing metabolic syndrome is 36 percent lower among vegetarians than non- vegetarians.This means that vegetarians are less likely to develop heart disease, diabetes and stroke -- three major conditions that are closely linked with metabolic syndrome, the researchers say.The study also found that vegetarians, though slightly older than non-vegetarians, had lower triglycerides, glucose levels, blood pressure, waist circumference, and body mass index (BMI). Semi-vegetarians, meanwhile, also had a significantly lower BMI and waist circumference compared to those who ate meat more regularly.The findings will not be affected by other factors such as age, gender, race, physical activity, calories consumed, smoking, and alcohol intake, the researchers say."In view of the high rate of metabolic syndrome in the United States and its deleterious health effects, we wanted to examine lifestyle patterns that could be effective in the prevention and possible treatment of this disorder," says lead researcher Nico S. Rizzo, PhD."I was not sure if there would be a significant difference between vegetarians and non-vegetarians, and I was surprised by just how much the numbers contrast," he says. "It indicates that lifestyle factors such as diet can be important in the prevention of metabolic syndrome."

CANBERRA, May 27 (Xinhua) -- An Australian student has discovered a part of the universe that astrophysicists have spent decades trying to find, Australia's Monash University on Friday confirmed in a statement.Astrophysicists have long thought the universe has a greater mass than is visible in the planets, but they had no way of proving it is there.Undergraduate student Amelia Fraser-McKelvie, 22, was on a summer internship at Monash University to learn more about astrophysics, when she managed to solve one of the big mysteries of science.Fraser-McKelvie, an aerospace engineering student, conducted a targeted X-ray search for the matter and found evidence of it within three months.Her tutor, Kevin Pimbblet, said the discovery is significant."We've been looking for this ordinary matter for a couple of decades," he said in a statement on Friday."It's been published in one of the most prestigious journals in the world, so astronomers all over the world will be able to read this article."Scientists had thought the matter would have a temperature of about 1 million degrees Celsius, 1.8 million degrees Fahrenheit, and should therefore be observable at X-ray wavelengths.Amelia Fraser-McKelvie's discovery has proved that prediction is correct, Pimbblet said.The trio published a research paper on the missing mass in one of the world's oldest and most prestigious scientific journals, Monthly Notices of the Royal Astronomical Society.He said the discovery could change the way telescopes are built.

BEIJING, Jan. 23 (Xinhua) -- Three years ago when Jason Shen stood on the Times Square for the first time, he didn't expect that a video clip he produced could be shown at the "Crossroads of the World"."In the eyes of an advertisement specialist, Times Square is a dream, where the biggest screen was as tall as a four-storey building and every day about 70,000 passengers could see the ads," said the chief executive officer of Shanghai Lowe & Partners advertising company.The company won the bidding of producing China's national publicity video in November 2009."Our biggest challenge was how to show a real China within just 60 seconds," he recalled.After brainstorming, his team agreed that the main theme should be human beings."The persons appearing in the video clip were like messengers to convey China's friendliness to the world," he said.The video was a step China takes in its foreign relations efforts, and a chance for Shen individually to fulfill a dream.Working as the chief executive producer, Shen gave some details in the filming of the video."Famous actress Zhang Ziyi was a very amiable person," he said. "She was very cooperative and the dress she wore was decided by arranged by our team."John Woo was excited hearing about the plan to make such a national publicity video work. "He told me that it was like reviewing the excitement when hearing China won the bidding of the 2008 Beijing Olympics."Deng Yaping, the four-time Olympic table tennis champion, was not sure how to pose in front of the camera."I told her that she just need to smile like when Ex-Olympic Chief Juan Antonio Samaranch put the gold medal around her neck," Shen said.All celebrities agreed to appear in the video free-of-charge.The smiling faces at the end of the 60-second video were gathered at the Shanghai World Expo, when it was hot and the temperature reached 40 degrees Celsius.But Shen and his team were left with some pity. "It was not easy to have six astronauts including Yang Liwei in the filming. But we could have made the video more lively by asking them to change more poses," he said.After the video was aired, Shen was sometimes questioned if the 59 persons in the short video could represent the entire of China."A good advertisement should give audiences strong visual impact and be enlightening," he said. "I believe that the celebrities and ordinary people from all walks of life could represent a mild and elegant image of China."The 60-second national publicity video is shown 15 times every hour on the Times Square from January 17 to February 14. It is expected to be aired on CNN from January 17 to February 13.A 15-minute documentary produced by the team, which is to be used at important events of Chinese embassies, was also finished. It will show the beautiful scenery of China.

BEIJING, April 12 (Xinhuanet) -- A new research indicats taking vitamin D could ward off vision loss from age-related macular degeneration (AMD) in women younger than 75, according to media reports on Tuesday.In the research, women under 75 who consumed sufficient vitamin D cut their risk of developing early age-related AMD, a leading cause of vision loss and blindness, by 59 percent when compared to women with vitamin D-poor diets.Researchers found that vitamin D levels among patients in the study were most affected by the amount of vitamin D they consumed, through certain fish, dairy, eggs, and leafy greens, not by the amount of outdoor exposure they had. Considering many Americans are actually deficient in vitamin D, this study may offer one more reason for women to include vitamin D-rich foods in the diet, said the lead author on the study, Amy Millen of the University of Buffalo.
