BEIJING, April 12 (Xinhuanet) -- The elderly have a difficult time with multi-tasking as a study suggests that older brains behave differently when it comes to switching between two tasks, according to media reports on Tuesday.Researchers used functional magnetic resonance imaging (FMRI) to analyze brain activity in 20 people over age 60 by asking them to contemplate outdoor photos shown briefly. Then the elderly were presented with the picture of a face and asked to determine its gender and age, before being asked to recall details from the original scene they viewed.Researchers then compared their results to a similar experiment with 20 younger adults and found the brains of older subjects were less capable of disengaging from the interruption and reestablishing the neural connections necessary to switch back to focusing on the original memory."Unlike younger individuals, older adults failed to both disengage from the interruption and re-establish functional connections associated with the disrupted memory network," write Wesley C. Clapp of the University of California, San Francisco, and colleagues in the Proceedings of the National Academy of Sciences.The study, published in the online edition of the journal Proceedings of the National Academy of Sciences, sheds new lights into a growing body of studies showing that one's ability to move from one task to another in quick succession becomes more difficult with age.

CHENGDU, Jan. 30 (Xinhua) -- Over the crowds of holiday shoppers in China's big stores this Spring Festival lingers an atmosphere of suspicion.With charges of price deception hanging over the big chains of Carrefour and Wal-Mart and local authorities moving to levy fines, many Chinese -- normally averse to be pinching pennies during the Lunar New Year -- are checking their receipts at the tills.The New Year, which falls on Feb. 3 this year, is normally a time of largesse and excess -- all the more reason why many shoppers feel so betrayed.Customers can be seen recording label prices in notebooks or calculating their final bill on their mobile phones as they walk the aisles.At outlets of Carrefour and Wal-Mart in cities such as Beijing, Shanghai and Chengdu, the check out queues have grown as customers doublecheck prices at the tills."I would never have imagined global firms would do this intentionally and I have to be cautious," said a woman surnamed Wang, after shopping at a foreign-owned supermarket in Chengdu, southwest China's Sichuan Province.With three bulging shopping bags, Wang stood next to the check out to calculate the final bill: "We buy a lot for the New Year celebrations, so I have to be more careful."The official weeklong Spring Festival holiday, which starts Wednesday, is China's closest equivalent to the West's Christmas shopping season, with generous gifts of food, tobacco, liquor and other presents for family and friends.According to the Ministry of Commerce, China's retail sales hit 340 billion yuan (49.8 billion U.S. dollars) during the Spring Festival holiday week last year."The deceptive pricing practices of the two foreign-funded supermarket giants were a total scandal," said Wang. "I have to be careful with the prices and the labels.""Cheating by the supermarkets is the same as stealing. I might have suffered losses as I don't normally check receipts," said a Chengdu man surnamed Li.Wal-Mart (China) Investment Co., Ltd. offered a "sincere apology" to affected customers on Thursday. The company has been cooperating with investigations into the cheating. It has also launched inspections of stores nationwide.Chen Bo, spokesperson for Carrefour China, said Sunday that Carrefour sincerely apologized to Chinese customers for inconvenience and losses caused by pricing irregularities.Carrefour would refund customers five times the difference between the price charged and that on the label. The refund policy would be implemented at Carrefour's 182 outlets in China.The issue is continuing to smoulder on the Internet, with websites asking people to write in with "your experiences of price cheating by the Carrefour."A survey by Sohu, one of China's major web portals, had resulted late Sunday in 8,451 of 9,507 respondents saying they "would not go to Carrefour as it is blacklisted for price cheating.""Carrefour will further strengthen price label management and improve service quality to gain the support and confidence of Chinese customers," said Chen Bo.Carrefour had drawn up short and long-term measures to solve the price label issue, including price inspections, improving and upgrading the price label system, and comprehensive staff training."We will have our special control group conduct frequent and wide-ranging internal price inspections," Chen said.The National Development and Reform Commission (NDRC), China's top economic planner and price regulator, said Wednesday that some Carrefour and Wal-Mart stores in China were involved in deceptive pricing practices.The NDRC ordered local pricing authorities to urge stores to correct their wrongdoing, and pay fines five times the illegal income. It also urged authorities to step up price checks ahead of the Spring Festival.

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.

LOS ANGELES, March 27 (Xinhua) -- Walnuts have a combination of more healthful antioxidants and higher quality antioxidants than any other nut, U.S. researchers have found.Study findings were presented on Sunday at the 241st National Meeting & Exposition of the American Chemical Society (ACS) in Anaheim, Southern California.Nuts contain plenty of high-quality protein that can substitute for meat, vitamins and minerals, dietary fiber, and are dairy- and gluten-free, ACS researchers said in the study.Moreover, nuts contain healthful polyunsaturated and monosaturated fats rather than artery-clogging saturated fat, according to the study.The researchers based their conclusion on analysis of antioxidants in nine different types of nuts: walnuts, almonds, peanuts, pistachios, hazelnuts, Brazil nuts, cashews, macadamias and pecans.They found that walnuts have the highest levels of antioxidants, with plenty of high-quality protein that can substitute for meat, vitamins and minerals, dietary fiber, and are dairy- and gluten-free.The latest study adds more evidence that walnuts are top nuts for heart-healthy antioxidants, the researchers said.Previous studies showed that regular consumption of small amounts of nuts or peanut butter can decrease the risk of heart disease, certain kinds of cancer, gallstones, Type 2 diabetes, and other health problems.But the latest study is the first to compare both the amount and quality of antioxidants found in different nuts."Walnuts rank above peanuts, almonds, pecans, pistachios and other nuts," said Joe Vinson, Ph.D., who led the latest study."A handful of walnuts contains almost twice as much antioxidants as an equivalent amount of any other commonly consumed nut. But unfortunately, people don't eat a lot of them. This study suggests that consumers should eat more walnuts as part of a healthy diet."

BEIJING, Jan. 30 (Xinhua) -- A total of 248 people were arrested in China last year for involvement in food safety cases, food safety authorities said Sunday.The country dealt with 130,000 cases involving food safety last year, including 115 criminal cases, according to a statement of the National Food Safety Regulating Work Office.The cases touched upon such areas as production of edible agricultural produce, food production, food circulation, catering services and food exports and imports,"No major incident occurred last year, and the overall food safety situation maintained stable," said the statement.Last year also saw a nationwide crackdown on "gutter oil", usually made from discarded kitchen waste that has been refined, after media reports that it was commonly used by small restaurants.Since July when the State Council, or Cabinet, ordered the eradication of "gutter oil", 165.7 tons of edible oil has been confirmed to have been disqualified and produced by unknown sources.Chinese authorities since July last year have also cracked down on the use of undisposed tainted milk powder produced before the melamine scandal of 2008.About 2,132 tonnes of melamine-tainted milk powder was seized in the latest crackdown, the statement said.A total of 191 officials were punished for failing to do their duty in food safety enforcement, with 26 of them fired, it said.In July last year, Dongyuan milk powder, produced in west China's Qinghai Province, was found to contain excessive levels of melamine, a toxic chemical normally used in the manufacturing of plastics, which triggered the nationwide crackdown.It is the latest blitz on tainted milk products since 2008 when melamine-tainted milk powder killed at least six infants and sickened 300,000 children across the country.
