LOS ANGELES, May 1 (Xinhua) -- Middle-aged adults who sleep too less or too much may be more likely to suffer cognitive decline, a new study suggests.According to the study, less than six hours of sleep each night is considered too little and more than eight hours as too much for middle-aged adults.The study, conducted by researchers at University College London Medical School, was published May 1 in the American medical journal Sleep.The researchers conducted the study in two periods -- the 1997- 1999 period and the 2003-2004 period. The participants were asked how many hours they slept on an average week night, and were asked the same question in 2003-2004 after an average 5.4 years of follow-up.The researchers compared those who reported changes in their sleep patterns with people whose sleep duration stayed the same over the course of the study.In the follow-up, each individual was given a battery of standard tests to assess his or her memory, reasoning, vocabulary, global cognitive status and verbal fluency.The study findings show that women who slept seven hours per night had the highest score for every cognitive measure, followed by those who had six hours of sleep. For men, cognitive function was similar for those who reported sleeping six, seven or eight hours.However, less than six hours of sleep -- or more than eight hours -- were associated with lower scores."Sleep provides the body with its daily need for physiological restitution and recovery," explained Jane Ferrie, a senior research fellow in the department of epidemiology and public health at the school. "While seven hours a night appears to be optimal for the majority of human beings, many people can function perfectly well on regular sleep of less or more hours."However, since most research has focused on the effects of sleep deprivation on biological systems, it is not yet fully understood why seven hours is optimal -- or why long sleeping appears to be detrimental, Ferrie said."Chronic short sleep produces hormones and chemicals in the body which increase the risk of developing heart disease and strokes, and other conditions like high blood pressure and cholesterol, diabetes and obesity," she added.

BEIJING, Feb.11 (Xinhua) -- Representatives from different sectors have given feedback on drafts of the government work report and China's economic and social development blueprint for the next five years, the State Council, China's cabinet, said Friday.Premier Wen Jiabao chaired five seminars from Jan. 20 to 27, at which representatives of various sectors of society were invited to voice their views on the documents, according to a State Council statement.The 12th five-year program, or the national development plan for 2011 to 2015, and the government work report will be delivered for review at the plenary session of the National People's Congress (NPC), China's top legislature, in March.Experts from social economic organizations along with those from science and technology, education, health, culture and sports circles attended the meetings, as well as members of non-communist parties.Participants at the seminars agreed on the framework and main content of the documents. They also gave some suggestions and proposed a couple of revisions to the report and the development plan.Most suggestions focused on China's economic restructuring, income distribution adjustment, modern agricultural development, scientific innovation, reform of the yuan exchange rate formation mechanism, property market regulation and affordable housing construction, and further improvement in education and medical care system.The forums also invited 11 grass-roots representatives, including farmers, technicians, and owners of small businesses, who raised suggestions to boost farmland irrigation construction, train more technicians, and help with the development of small and medium enterprises.Wen said the feedback will be "of great help" when revising both the government work report and 12th five-year plan, as well as to the work of the government.

BEIJING, Feb. 14 (Xinhua) -- A recent circular of China's film and television watchdog to cut smoking scenes in films and TV dramas has received welcome from supporters of tobacco control.Xu Guihua, deputy head of China Association on Tobacco Control (CATC), a non-profit organization, said the order of the State Administration of Radio, Film and Television (SARFT) demonstrates government determination to protect public health rights."Frequent smoking scenes in films and TV dramas do not accord with China's stance on tobacco control and mislead the public, especially the youth," said the SARFT in a recent circular.Tobacco brands or signs and smoking scenes with juveniles present should not be allowed to appear in films or TV dramas, it said, adding that scenes which have to show smoking should "last as short as possible."Hailing the order, Xu said the communication through media including movies and TV is among those factors that can influence people's attitude toward smoking.Deng Haihua, a spokesman with China's Ministry of Health, also said the SARFT's move will help prevent people, especially the young, from being misled by smoking scenes on screens.In a survey report issued in August 2010, the CATC said it found smoking scenes in 31 movies and 28 TV series after monitoring 40 Chinese movies and 30 local TV series.Another survey by Beijing Municipal Center for Disease Control and Prevention also showed students tend to follow the fashion after seeing actors smoke on TV or in films.China has more than 300 million smokers and 540 million more suffering from secondhand smoke.What is especially worrisome is that 11.5 percent of the country's juvenile smoke and the ratio is even increasing, according to experts.

WASHINGTON, March 9 (Xinhua) -- U.S. space shuttle Discovery landed safely at the Kennedy Space Center in Florida on Wednesday, ending its nearly 27-year flying career as the world's most- traveled spaceship.According to NASA, Discovery touched down at 11:57 a.m. EST ( 1657 GMT) after a 13-day resupply mission to the International Space Station (ISS)."For the final time: wheels stop," Discovery's commander Steven Lindsey called out as the shuttle rolled to a full stop.Discovery lifted off on Feb. 24 from the Kennedy Center and arrived at the space station on Feb. 26.During the mission, the astronauts installed a spare closet module on the space station, completed some important repairs and delivered the first humanoid robot, though it will need more time to be assembled and made operational.The 330-pound R2 consists of a head and a torso with two arms and two hands. Once it is unpacked -- likely several months after its arrival at the station -- it will initially be operated inside the Destiny laboratory for operational testing, but over time both its territory and its applications could expand.Aboard the station, its primary job for now is teaching engineers how dexterous robots behave in space. However, the hope is that through upgrades and advancements, it could one day venture outside the station to help spacewalkers make repairs or additions to the station or perform scientific work.

BEIJING, Feb. 5 (Xinhua) -- Despite profound changes in the global economy, China's banking industry expects steady growth during the 12th Five-Year Plan (2011-2015), a senior banker said Saturday.China's steady and relatively fast economic growth is expected to lay a solid basis for the development of the commercial banks' main businesses, said Hu Huaibang, chairman of Bank of Communications, the fifth-largest lender.Meanwhile, the transformation of China's economic growth pattern would provide an impetus to the adjustment and optimization of the lenders' businesses, Hu said.Hu predicted businesses, such as consumer credit, asset management and credit cards, would enter a golden era over the next few years, along with the economy's shift to a domestic consumption-driven model from the current export-oriented growth pattern.Also, increases in personal wealth and growing numbers in the middle class would bring huge potential customers and development opportunities to the lenders, Hu said.Further, he urged Chinese banks to improve their services and launch new products to meet diversified demands.
