BEIJING, Aug. 3 (Xinhuanet) -- NASA Tuesday confirmed a 4-foot in diameter sphere debris as a fuel tank that was part of the space shuttle Columbia's electrical power system,according to U.S. news reports.NASA engineers identified the 4-foot piece of spherical debris as one of the18 tanks that held chilled oxygen and hydrogen used by the shuttle's electricity-generating fuel cells.This Aug. 1, 2011 handout photo provided by the Nacogdoches Police Department shows a 4-feet in diameter sphere found in Lake Nacogdoches, Texas on Monday, Aug. 1. Police say low water levels at the lake during the drought have led to recovery of a container-like object that could be from space shuttle Columbia. The shuttle broke apart and burned in February 2003, scattering remnants over East TexasPolice in the city of Nacogdoches, about 160 miles northeast of Houston, said Monday the low water levels of Lake Nacogdoches during the record drought revealed an unexpected object that could be from space shuttle Columbia. The shuttle broke apart and burned as it re-entered the atmosphere on February 1, 2003.The tank will be moved to the Kennedy Space Center, where the rest of the Columbia is stored. Approximately 40 percent of the spacecraft has been recovered.

BEIJING, June 26 (Xinhua) -- China on Sunday issued a regulation on drug rehabilitation that encourages drug users to voluntarily undergo rehabilitation programs.The regulation took effect Sunday as a supplement of the country's anti-drug law that was implemented three years ago.Drug users who voluntarily receive intervention programs "will be exempt from punishment," said the regulation, promulgated on the 24th International Day Against Drug Abuse and Illicit Trafficking, which falls on Sunday.With seven chapters and 46 articles, it also stipulates the rights and obligations of drug addicts, as well as supporting measures for voluntary, community-based, and government-ordered drug rehabilitation.Up to date, more than two million Chinese have been receiving compulsive rehabilitation or treatment, statistics show. However, many of them find it difficult to completely give up the addiction.The regulation, aiming to explore effective ways to curb drug use, calls for boosting "the role of communities and families" in helping reduce drug users' dependency on narcotics.It asks rehabilitation centers to provide addicts with consulting services and education on the prevention of HIV/AIDS and other contagious diseases.Efforts should be made to "boost pharmaceutical management" so as to prevent loss or abuse of psychotropic substances and narcotics, the regulation says.The regulation also stipulates on the protection of drug addicts' personal information, saying "members of the police, judiciary and health departments who cause the leak of personal information must be punished."The regulation has solicited public comments before it was released.Transnational drug trafficking remains rampant in China, particularly in southwestern border regions of Yunnan and Guangxi.A report issued last month by China's National Narcotics Control Commission said authorities investigated 89,000 drug-related crimes and arrested 101,000 suspects last year.Law enforcers confiscated 5.3 metric tonnes of heroin and one metric tonne of opium in 2010, the report said, adding that intervention programs were used to treat and rehabilitate some 175,000 drug addicts last year.

SAN FRANCISCO, June 17 (Xinhua) -- A new research released on Friday shows that smartphone users in the United States are consuming more data than ever, growing by 89 percent in the first quarter on a year-over-year basis.According to data from marketing company Nielsen, the amount of data the average smartphone user consumes per month is 435 Megabytes (MB) in the first quarter of 2011, compared with 230 MB in the same period last year.As for the distribution of data consumption, data usage for the top 10 percent of smartphone users is up 109 percent while the top 1 percent has grown their usage by 155 percent from 1.8 Gigabytes (GB) in the first quarter of 2010 to over 4.6 GB this year.The research said consumers with iPhones and Android smartphones consume the most data, which is driven by app-friendly operating systems like Apple's iOS and Google's Android. Windows Phone 7 users doubled their usage over the fourth quarter of 2010 and the first quarter of 2011, perhaps due to growth in the number of applications available.Meanwhile, the cost per MB for smartphones has dropped by 46 percent over the last year, from 14 cents per MB to 8 cents, said the research.According to Internet marketing research company comScore, in the first quarter of 2011, 234 million Americans ages 13 and older used mobile devices, 74,6 million of whom are smartphone users.

LOS ANGELES, July 28 (Xinhua) -- Mainly due to rampant obesity, Americans' life expectancy is one-and-a-half-year shorter than that of Western Europeans on the average, according to a new study published on Thursday.But 40 years ago, Americans could expect to live slightly longer than Europeans, said the study jointly conducted by researchers from University of Southern California (USC), the Harvard School of Public Health and the RAND Corp., a non-profit think tank.In addition to Western Europeans, Americans also die younger than the residents of most other developed nations, according to the study appearing in the July issue of Social Science & Medicine.The life-expectancy disparity, which begins around the age of 50, stems from higher levels of middle-age obesity and obesity-related chronic diseases, such as hypertension and diabetes, said the study.In the first half of the last century, average life expectancy increased by saving more babies, said author Dana Goldman, director of the Schaeffer Center for Health Policy and Economics at the USC."But now it is reduction in mortality among the elderly, rather than the young, that propels increases in life expectancy," he said. "The question is whether 'being American' is an independent mortality risk factor."If 50-year-old U.S. adults could be as healthy as Europeans, it could save Medicare and Medicaid 632 billion dollars by 2050, the study said.Though the transition to better health initially raises expenditures, the researchers estimate that by 2050 healthcare savings from health improvements among the middle age could total more than 1.1 trillion dollars."The international life expectancy gap appears much easier to explain than gaps within countries: there is no American-specific effect on longevity beyond differences in disease at age 50," said Darius Lakdawalla, an associate professor in the USC School of Policy, Planning and Development.

WASHINGTON, Aug. 11 (Xinhua) -- The unique fossils of an adult plesiosaur and its unborn baby may provide the first evidence that these ancient animals gave live birth like mammals, according to a new study to be published Friday in the journal Science.The 78-million-year-old, 15.4-foot-long (4.7-meter-long) adult specimen is a Polycotylus latippinus, one of the giant, carnivorous, four-flippered reptiles that lived during the Mesozoic Era.Dr. Robin O'Keefe of Marshall University in West Virginia and Dr. Luis Chiappe, Dinosaur Institute director of the Natural History Museum in Los Angeles County, have determined that it is the fossil of an embryonic marine reptile contained within the fossil of its mother.The embryonic skeleton contained within shows much of the developing body, including ribs, 20 vertebrae, shoulders, hips, and paddle bones.O'Keefe and Chiappe have also determined that plesiosaurs were unique among aquatic reptiles in giving birth to a single, large offspring, and that they may have lived in social groups and engaged in parental care.Although live birth has been documented in several other groups of Mesozoic aquatic reptiles, no previous evidence of it has been found in the important order of plesiosaurs."Scientists have long known that the bodies of plesiosaurs were not well suited to climbing onto land and laying eggs in a nest," O'Keefe said."So the lack of evidence of live birth in plesiosaurs has been puzzling. This fossil documents live birth in plesiosaurs for the first time, and so finally resolves this mystery."
