SAN FRANCISCO, Aug. 22 (Xinhua) -- Hewlett-Packard's tablet TouchPad has become the hottest consumer electronics device on Monday after HP launched a fire sale for the discontinued product line over the weekend."It was like a stampede and they went quick," a Best Buy employee in San Diego told technology news website Betanews, describing the line waiting to buy TouchPad. He said the discontinued tablet was sold out five minutes after the store opened.The device is also getting snatched up at a lighting speed online and increasingly difficult to find.The TouchPad is no longer listed on Bestbuy.com in the United States, which last week was reportedly sitting on 270,000 unsold TouchPads and was hoping HP would buy them back.On Amazon, TouchPad tops the world's largest online retailer's electronics sales list, beating out the electronic reader Kindle and iPod touch.Last Thursday, HP announced that it will completely shut down its webOS operations, specifically the TouchPad tablet and webOS phones.The 16 GB TouchPad currently is only 99.99 U.S. dollars, compared to the original price of 399 dollars. The 32 GB model, which used to be 485.99 dollars, is now priced at 149.99 dollars.

SYDNEY, July 1 (Xinhua) -- Breastfeeding mothers should limit their use of codeine-containing painkillers to four days as they can cause harm, an Australian doctor warned on Friday.The warning is being discussed at a meeting of anesthetists in Sydney."New mothers should limit their use of codeine-containing painkillers to no more than four days and, if they feel drowsy while taking this medication, cease its use and have their baby examined by a doctor for signs of drowsiness," Sydney's Royal North Shore Hospital anesthetist Dr. Gavin Pattullo said."This is because codeine needs to be metabolized by the liver into morphine to offer pain relief and this liver conversion process is very unpredictable," Pattullo said."Some patients' livers produce large amounts of morphine after taking codeine, causing drowsiness, while others fail to produce any morphine at all."Pattullo said for breastfeeding mothers, a large dose of morphine could make its way into the baby and result in the baby's death by overdose."While new mums shouldn't be unnecessarily alarmed, they need to be aware that codeine-containing painkillers in certain circumstances can cause harm," he said.Breastfeeding mothers are being advised to see a doctor if their baby gets sleepy while taking the painkillers.

SAN FRANCISCO, July 12 (Xinhua) -- Google+, the social networking service Google unveiled only two weeks ago, is estimated to surpass 10 million users on Tuesday, possibly becoming the fastest growing product in the history of the Internet.According to Ancestry.com founder Paul Allen (not the co- founder of Microsoft), after passing 10 million users, Google+ " could reach 20 million users by this coming weekend if they keep the Invite Button available."Allen looks for last names on Google+ and compares them with U. S. Census Bureau data on the popularity of surnames to statistically project the number of Google+ users."Since I have been tracking this same cohort of surnames from my first day, I am able to accurately measure growth over time," he said in a blog post on Google+ website.Google so far has not released any details about the Google+ users or the number of users. Speaking at a press event last Thursday in Sun Valley in the U.S. state of Idaho, former Google CEO and current Executive Chairman Eric Schmidt said there are " millions" of users.Industry watchers think the estimate may not be completely accurate, but Allen should be capturing the growth trajectory of Google+, which shows that a social network could undergo an exponential growth in its early days.

BEIJING, Sept. 2 (Xinhuanet) -- The amount of space junk orbiting the Earth could cause fatal leaks in spaceships or destroy valuable satellites, according to a report released by the U.S. National Research Council.Computer models have shown that the number of orbital debris "has reached a tipping point, with enough currently in orbit to continually collide and create even more debris, raising the risk of spacecraft failures," the Research Council said Thursday.So far, there are 22,000 pieces of debris large enough to track from the ground, but smaller objects could still cause serious damage.New international regulations are needed to limit space junk.And more researches should be done to test the possible use of launching magnetic nets or giant umbrellas to push the debris further towards the Earth where it would burn up, or into a higher but safer orbit.

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.
