BEIJING, May 14 (Xinhua) -- The uranium subsidiary of China Guangdong Nuclear Power Group (CGNPG) has said it is developing two large mines in the mainland.The two mines will be located in south China's Guangdong province and northwest China's Xinjiang Uygur Autonomous Region, according to Saturday's China Daily.The move is likely to add as much as 1,000 tonnes to the country's annual production capacity of the nuclear fuel."The two mines are expected to start operation in 2013, each with an annual production capacity of no more than 500 tonnes," the newspaper quoted Zhou Zhenxing, chairman of CGNPG Uranium Resources Co (CGNPG-URC) as saying.

LOS ANGELES, March 3 (Xinhua) -- More and more American adults are suffering from a decline in overall sleep duration, the U.S. Centers for Disease Control and Prevention (CDC) said on Thursday.It's recommended that adults should sleep seven to nine hours a night to maintain good health, but more than one-third of Americans do not meet that requirement, according to the CDC.Insufficient sleep poses a long-term heath threat and impairs work performance and the ability to drive safely, the CDC said.Chronic sleep loss also is associated with obesity, increased risk of death and other health problems, according to the CDC."Over the last 20 years there has been a decline in overall sleep duration in adults," said Lela McKnight-Eily, a clinical psychologist and epidemiologist at the CDC's National Center for Chronic Disease Prevention."Within our culture there seems to be a belief that sleep isn't a part of overall essential health," she said.McKnight-Eily and her colleagues studied the sleep habits of 74,571 adults in 12 states, 35.3 percent reported sleeping less than seven hours.In addition, 48 percent reported snoring, 37.9 percent said they fell asleep at least once during the day the previous month and 4.7 percent admitted to falling asleep at the wheel at least once.Drowsiness or nodding off while driving accounts for 1,550 deaths and 40,000 injuries a year, according to the U.S. Department of Transportation.To get enough sleep, Americans have to change lifestyle habits, including longer workdays and late nights on the computer, McKnight-Eily said, noting that too much screen time paring away much-needed sleep time.

BEIJING, Feb. 10 (Xinhua) -- China's drought control authorities announced Thursday that hours of snowfall and irrigation have eased to some extent the severe drought in parts of the nation.Rapid spreading of the dry spell in the country's winter wheat producing regions has been curbed by wide-spread snowfall in the areas along the Yangtze, Huaihe and Yellow rivers and in the country's northern part on Wednesday and Thursday, the Office of State Flood Control and Drought Relief Headquarters said in a statement on its website.Drought-hit areas in Henan and Anhui, which are two major wheat-producing provinces, were reduced by 6.3 million mu (420,000 hectares) and 4.1 million mu, respectively, from Wednesday, the statement said. The agency added that irrigation also contributed to easing the effects of the drought.The statement said that as of Thursday, eight drought-hit provinces had irrigated 143 million mu of drought-affected wheat producing areas, which accounts for 52 percent of the combined winter wheat producing areas in the provinces. The eight provinces include the territories of Shandong, Henan, Hubei, Anhui, Shanxi, Shaanxi, Gansu and Jiangsu.As of 3 p.m. Thursday, the drought had affected 101.28 million mu of crops nationwide and left 2.81 million people and 2.57 million heads of livestock short of drinking water, said the statement.Cloud seeding on Wednesday and Thursday during a recent cold front, also helped alleviate drought in some regions, according to a report posted on the website of the China Meteorological Administration on Thursday.The report also said that the artificial precipitation had mitigated the shortage of moisture in the soil in parts of Henan and Anhui. The situation is expected to improve as the rain and snow continues.However, experts urged more measures from local governments to ensure winter wheat production since the current precipitation is not adequate to "completely ease the drought", the report said.

BEIJING, May 12 (Xinhuanet) -- Italian archaeologists are digging the remains of Lisa Gherardini, a 16th-century woman who is widely believed to be the model for the famous portrait Mona Lisa, AFP reported on Wednesday.The team of historians say they will try to find the remains using geo-radar equipment and then try to re-create a likeness of what the woman, Lisa Gherardini, would have looked like to compare her to Leonardo Da Vinci's Mona Lisa.Gherardini (1479-1542), also known by her married name as Lisa del Giocondo, was the wife of a Florentine silk merchant and is widely believed to have been the model for the  portrait that now hangs in the Louvre in Paris.But the issue has never been settled definitively and mystery still shrouds the model's enigmatic expression and other details of the portrait.
