BEIJING, Feb. 8 (Xinhua) -- China would continue expanding its radio and television networks coverage in the country's rural areas in the 2011-2015 period, according to the State Administration of Radio, Film and Television (SARFT).In the five-year period, efforts would focus on ensuring access to radio and TV services in those villages with less than 20 households, the SARFT said in a statement.It noted that China's other villages which had more than 20 households were already covered by the radio and TV networks, thanks to government's continuous efforts in this regard.China's central and local governments poured over 15.7 billion yuan (2.38 billion U.S. dollars) into the upgrading of the radio and TV networks in the country's rural areas in 2006-2010.Official figures indicated that 96.31 percent and 97.23 percent of China's population had access to radio and TV services respectively in 2009. The ratio was 86.02 percent and 87.68 percent respectively in 1997.

WASHINGTON, April 3 (Xinhua) -- In the largest study of its kind, researchers from a consortium led by the University of Pennsylvania School of Medicine, the University of Miami, and the Boston University School of Medicine, identified four new genes linked to Alzheimer's disease. The findings appeared Sunday in the current issue of Nature Genetics.Each gene individually adds to the risk of having this common form of dementia later in life. These new genes offer a portal into what causes Alzheimer's disease and is a major advance in the field.The study, conducted by the Alzheimer's Disease Genetics Consortium, reports genetic analysis of more than 11,000 people with Alzheimer's disease and a nearly equal number of elderly people who have no symptoms of dementia. Three other consortia contributed confirming data from additional people, bringing the total number of people analyzed to over 54,000. The consortium also contributed to the identification of a fifth gene reported by other groups of investigators from the United States, the United Kingdom, France, and other European countries.The study is the result of a large collaborative effort with investigators from 44 universities and research institutions in the United States, led by Gerard Schellenberg at University of Pennsylvania."This is the culmination of years of work on Alzheimer's disease by a large number of scientists, yet it is just the beginning in defining how genes influence memory and intellectual function as we age. We are all tremendously excited by our progress so far, but much remains to be done, both in understanding the genetics and in defining how these genes influence the disease process," Schellenberg said.Until recently, only four genes associated with late-onset Alzheimer's have been confirmed, with the gene for apolipoprotein E-e4, APOE-e4, having the largest effect on risk. The Nature Genetics studies add another four -- MS4A, CD2AP, CD33, and EPHA1 -- and contribute to identifying and confirming two other genes, BIN1 and ABCA7, thereby doubling the number of genes known to contribute Alzheimer's disease.

BEIJING, Jan. 26 (Xinhua) -- There is some part of China that could use additional water -- the drought-hit north, even while the central government is grappling to soak up excess liquidity to contain price hikes.The dry spell has continued for months in the grain production regions in northern China, setting off concerns that it might threaten China's grain output and thus cause food price hikes, a major contributor of the country's inflation in recent months.The bad weather came and may aggravate China's battle on price hikes, including higher interest rates and reserve ratios. The government also introduced price caps and promised increases in supplies to stabilize prices.Meteorological and agricultural experts said it is still too soon to predict a decline in grain output. However, they worried that if the drought continues into the spring, grain output will fall and push up food prices.DRY SPELLWater shortages have been gripping nine provinces since October last year, including the six major wheat producing regions in China -- Shanxi, Shandong, Hebei, Henan, Anhui and Jiangsu -- which contribute more than 80 percent of the country's total wheat output.Further, rainfall in the six provinces averaged only 40.2 millimeters since October last year, down 53 percent compared with previous years, according to the National Climate Center.As of Monday, 60.39 million mu (4.02 million hectares) of crops throughout the nation were plagued by drought, according to the latest statistics from the Office of State Flood Control and Drought Relief Headquarters."There have been no rains for four months. It has been too long," said Song Qingguo, a farmer at the Xitiegang village of Qixian County in Henan, where winter wheat output accounts for almost one-fourth of the country's total."Wheat output will probably drop if such a situation continues," he worried.At present, some 15.86 million mu of wheat is exposed to drought, according to Yang Biantong, an official with Henan's water authorities.Another key wheat growing province of Shandong is facing its worst drought in 60 years, local authorities said. About 2 million hectares of land used for growing wheat, or 56 percent of the wheat-planting areas in the province, have been hit by drought, and the area is expanding, the Shandong provincial flood control and drought relief headquarters said.H Scientists say it is a result of the La Nina effect that is also responsible for the harsh winter gripping large parts of China's south, which also affected production and transportation of vegetables and other food.The Ministry of Commerce said Tuesday that Chinese farm produce prices rose for a fourth consecutive week, through Jan. 23, with the wholesale prices of 18 staple vegetables growing 12.6 percent week on week. One reason for the price hike was the freezing weather in the south, it said."The current drought in China is the second worst during the same period of time since 1961 because of the adverse weather", said Zhang Peiqun, director with the weather forecast department of the National Climate Center.The bad weather will persist in the following period of time, which means the drought in the north and the cold snap in the south will continue, Zhang said.The China Meteorological Administration forecast on Wednesday that parts of Hubei, Hunan, Anhui and Zhejiang provinces will have heavy snow or snowstorms in the coming three days. Also, icy rain will slash parts of Guizhou and Yunnan provinces.

GENEVA, May 3 (Xinhua) -- Roughly half to three quarters of adults aged between 18 to 65 years have had headache in the last year, a prevalent problem that went under-treated, the Geneva based World Health Organization (WHO) said in a report issued Tuesday.The report, named "Of Headache Disorders and Resources in the World 2011," regarded headache disorders as one of the most prevalent disorders of mankind.WHO estimated over 10 percent of the adult population suffered from migraine, and 1.7 to 4 percent of them were troubled frequently by headache on 15 or more days every month.Among all cases studied, the report said, on average only 10 percent were treated by neurologists, and the rates were even lower in Africa and South-East Asia.Three types of headache disorders were underlined as the most frequently seen, including migraine, tension-type headache and that caused by medication-overuse.The report concluded that given the very high indirect costs of headache, investment in health care related to headache treatment might be overall cost-saving to society.
