BEIJING, Feb. 10 (Xinhua) -- The Chinese currency, or the yuan, on Thursday rose to a fresh high of 6.5849 against the U.S. dollar, according to the China Foreign Exchange Trading System.The central parity rate of the yuan, or RMB, was 1 basis point higher than the previous record of 6.585 set on Feb. 9, the previous trading day.The central parity rate has risen against the dollar for a three consecutive trading days.China's central bank announced on June 19 last year that it would further reform the yuan exchange rate formation mechanism to improve its flexibility.On China's foreign exchange spot market, the yuan can rise or fall 0.5 percent from the central parity rate each trading day.The central parity rate of the RMB against the U.S. dollar is based on a weighted average of prices before the opening of the market each business day.

BEIJING, Jan. 21 (Xinhua) -- Chinese Vice Premier Li Keqiang on Friday stressed the importance that local governments improve management of land and resources, as it remains vital for the stable and relatively quick development of the nation's economy.Li said China faced the difficult tasks of land and resource management as resources are becoming scarce amid the country's quickening industrialization, urbanization, and agricultural modernization.He said the nation must continue preserving arable land. To ensure grain security, China set a "red line" to guarantee its arable land never shrinks to less than 1.8 billion mu (120 million hectares).Chinese Vice Premier Li Keqiang (R) shakes hands with outstanding representatives from local departments in charge of land and resources in Beijing, capital of China, Jan. 21, 2011.Li also called on local authorities to step up efforts to protect valuable mineral resources while using resources more efficiently and in a frugal manner.At the same time, the senior Chinese official said land should be guaranteed for the nation's plan to build 10 million affordable houses for low and middle income people this year.Further, Li urged local authorities to improve work in monitoring and taking precautionary measures against geological disasters to ensure the safety of people's lives and property.

WASHINGTON, May 3 (Xinhua) -- People diagnosed with asthma in the United States grew by 4.3 million between 2001 and 2009, according to a new report released Tuesday by the Centers for Disease Control and Prevention (CDC).In 2009, nearly one in 12 Americans were diagnosed with asthma. In addition to increased diagnoses, asthma costs grew from about 53 billion U.S. dollars in 2002 to about 56 billion dollars in 2007, about a six percent increase. The explanation for the growth in asthma rates is unknown, according to the CDC.Asthma is a lifelong disease that causes wheezing, breathlessness, chest tightness, and coughing, though people with asthma can control symptoms and prevent asthma attacks by avoiding things that can set off an asthma attacks, and correctly using prescribed medicine, like inhaled corticosteroids. The report highlights the benefits of essential asthma education and services that reduce the impact of these triggers, but most often these benefits are not covered by health insurers."Despite the fact that outdoor air quality has improved, we've reduced two common asthma triggers -- secondhand smoke and smoking in general -- asthma is increasing," said Paul Garbe, chief of CDC 's Air Pollution and Respiratory Health Branch. "While we don't know the cause of the increase, our top priority is getting people to manage their symptoms better."Asthma triggers are usually environmental and can be found at school, work, home, outdoors, and elsewhere and can include tobacco smoke, mold, outdoor air pollution, and infections linked to influenza, cold-like symptoms, and other viruses.According to the report, asthma diagnoses increased among all demographic groups between 2001 and 2009, though a higher percentage of children reported having asthma than adults (9.6 percent compared to 7.7 percent in 2009). Annual asthma costs in the United States were 3,300 dollars per person with asthma from 2002 to 2007 in medical expenses. About two in five uninsured and one in nine insured people with asthma could not afford their prescription medication."Asthma is a serious, lifelong disease that unfortunately kills thousands of people each year and adds billions to our nation's health care costs," said CDC Director Thomas Frieden. "We have to do a better job educating people about managing their symptoms and how to correctly use medicines to control asthma so they can live longer more productive lives while saving health care costs."

WASHINGTON, April 20 (Xinhua) -- Those childhood music lessons could pay off decades later -- even for those who no longer play an instrument -- by keeping the mind sharper as people age, according to a preliminary study published by the American Psychological Association (APA).The study recruited 70 healthy adults age 60 to 83 who were divided into groups based on their levels of musical experience. The musicians performed better on several cognitive tests than individuals who had never studied an instrument or learned how to read music, according to the research findings published Wednesday online in the APA journal Neuropsychology."Musical activity throughout life may serve as a challenging cognitive exercise, making your brain fitter and more capable of accommodating the challenges of aging," said lead researcher Brenda Hanna-Pladdy, a clinical neuropsychologist at the University of Kansas Medical Center. "Since studying an instrument requires years of practice and learning, it may create alternate connections in the brain that could compensate for cognitive declines as we get older."The three groups of study participants included individuals with no musical training; with one to nine years of musical study; or with at least 10 years of musical training. All of the participants had similar levels of education and fitness and didn' t show any evidence of Alzheimer's disease.All of the musicians were amateurs who began playing an instrument at about 10 years of age. More than half played the piano while approximately a quarter had studied woodwind instruments such as the flute or clarinet. Smaller numbers performed with stringed instruments, percussion or brass instruments.The high-level musicians who had studied the longest performed the best on the cognitive tests, followed by the low-level musicians and non-musicians, revealing a trend relating to years of musical practice. The high-level musicians had statistically significant higher scores than the non-musicians on cognitive tests relating to visuospatial memory, naming objects and cognitive flexibility, or the brain's ability to adapt to new information.The brain functions measured by the tests typically decline as the body ages and more dramatically deteriorate in neurodegenerative conditions such as Alzheimer's disease. The results "suggest a strong predictive effect of high musical activity throughout the lifespan on preserved cognitive functioning in advanced age," the study stated.Half of the high-level musicians still played an instrument at the time of the study, but they didn't perform better on the cognitive tests than the other advanced musicians who had stopped playing years earlier. This suggests that the duration of musical study was more important than whether musicians continued playing at an advanced age, Hanna-Pladdy says."Based on previous research and our study results, we believe that both the years of musical participation and the age of acquisition are critical," Hanna-Pladdy says. "There are crucial periods in brain plasticity that enhance learning, which may make it easier to learn a musical instrument before a certain age and thus may have a larger impact on brain development."The preliminary study was correlational, meaning that the higher cognitive performance of the musicians couldn't be conclusively linked to their years of musical study. More research is needed to explore that possible link.

SAN FRANCISCO, April 7 (Xinhua) -- A latest research has shown that worldwide camera phone sales, driven by fast growing high- tier camera phone market, will top 1 billion units for the first time in 2011.According to the study by Strategy Analytics, a global independent research and consulting firm, sales of camera phones are projected to grow by 21 percent from 918 million units last year to 1.114 billion units in 2011, which will be the first time that annual volumes of camera phones have exceeded the 1-billion mark."The fastest growing segment of the camera phone market will be the high-tier. We forecast camera phones with sensors of eight megapixels and above to grow a healthy 240 percent worldwide during 2011," Neil Mawston, director at Strategy Analytics, said in a statement on Thursday.He added that smartphone vendors, such as Nokia and HTC, are increasingly loading their flagship models with more megapixels to deliver improved imaging quality for premium operator services.Statistics from Strategy Analytics show that some 4.2 billion camera phones have been sold worldwide since 2000.
