SAN FRANCISCO, Aug. 22 (Xinhua) -- Hewlett-Packard (HP) on Monday unveiled a new business desktop computer, days after the world's largest personal computer (PC) maker announced its plan to sell its PC business.The company said the new model, HP Compaq 8200 Elite All-in-One Business Desktop, is the industry's first all-in-one PC that integrates Intel's second-generation Core vPro technology, which can deliver up to 40 percent better performance, 15 percent faster hard drive access and reduced downtime via remote information technology management."Another industry first in our Elite desktop family demonstrates our commitment to engineering excellence and underscores our global leadership in secure, enterprise computing, " Jeff Groudan, HP's director of commercial desktop marketing, said in a statement.HP said the new computer is available now in the United States. It starts at the price of 999 U.S. dollars, and comes with a standard three-year warranty.Last Thursday the company announced that it is considering a full or partial separation of its PC business through a spin-off or other transactions, a process that HP estimates may take about 12 to 18 months.

CHICAGO, Aug. 25 (Xinhua) -- Gold futures on the COMEX Division of the New York Mercantile Exchange on Thursday bounced off the biggest drop since March 2008, as the weakness in stock market enhanced appeal of gold as a safe-have investment.The most active gold contract for Dec. delivery gained 5.9 U.S. dollars, or 0.3 percent, to 1,763.2 dollars per ounce. The metal suffered on Wednesday the biggest one-day drop since March 19, 2008.Market analysts said that gold extended losses in earlier trading, hit by a margin-requirement increase, but the drop in global stock market gave a push to the metal. Both Dow Jones industrial average and S&P 500 declined on Thursday after a 3-day rise as a government report showed U.S. jobless claims rose last week.Besides, market hearsay went that Germany might be next to get a sovereign-debt downgrade, adding to the positive tone on gold market. German equity market also suffered sharp drop in the day.Many market watchers remained long-term bullish attitude toward gold although they said the precious metal could correct further in the short term. A trader noted that the fundamental factors driving uncertainty and fears are all still there.Expectations are growing that the Federal Reserve Chairman Ben Bernanke would not provide any form of stimulus in a speech scheduled for Friday at a yearly gathering of central bankers in Jackson Hole.Silver for Sept. delivery also rose 1.583 dollars, or four percent, to 40.745 dollars per ounce. Platinum for Oct. delivery lost 3.9 dollars, or 0.2 percent, to 1822.4 dollars per ounce.

RIO DE JANEIRO, Sept. 26 (Xinhua) -- Rio de Janeiro has the highest level of air pollution in Brazil, and is more polluted than many other world metropolis like New York, London and Paris, a World Health Organization (WHO) study said Monday.According to the study, which was carried out in 91 countries and regions, the air in Rio's metropolitan area contains 64 micrograms of fine particulate matter per cubic meter, over three times the upper limit set by the WHO, which is 20 micrograms per cubic meter.Despite being larger, having a bigger population and more vehicles, Sao Paulo's metropolitan area has less air pollution, with 38 micrograms of fine particulate matter per cubic meter.According to the WHO, "the largest contributors to urban outdoor air pollution include motor transport, small-scale manufacturers and other industries, burning of biomass and coal for cooking and heating, as well as coal-fired power plants." The organization said that residential wood and coal burning for heating also help increase air pollution, especially in rural areas in the cold months.The WHO expressed concern over air pollution levels in several cities, as some two million people worldwide die annually from conditions resulting from air pollution."Air pollution is a major environmental health issue, and it is vital that we increase efforts to reduce the health burden it creates," said Dr. Maria Neira, WHO's director for Public Health and Environment.According to the study, Ahwaz, Iran, has the most polluted air in the world, with 372 micrograms of fine particulate matter per cubic meter.

CANBERRA, Sept. 7 (Xinhua) -- A team of Australian and U.S. scientists on Wednesday said they discovered a genetic defect, which can lead to Leigh syndrome, a rare disorder which affects the central nervous syndrome.The scientists tested more than 1000 genes by encoding proteins active in two individuals who suffer from the illness. They used a new technique known as next-generation DNA sequencing to examine the genes.The gene they discovered encodes an enzyme which is found in the mitochondria which are subsets of cells. Without this enzyme the mitochondria do not translate proteins efficiently, and this then causes Leigh syndrome.According to David Thorburn, from the Murdoch Children's Research Institute in Melbourne, the discovery shows the enormous potential of the new technology."These findings demonstrate the ability of sequencing technologies to improve diagnosis," Professor Thorburn said in a statement released on Wednesday."Although it isn't clear in the case of Leigh syndrome whether the precise molecular diagnosis will necessarily lead to therapies, the current findings represent a meaningful service."He added that diagnosis of the disease along with its specific genetic cause can also be informative about the risk a couple has of having another affected child. The diagnostic information can help in decisions about whether and how to pursue alternative means of having children, for instance through the use of donor sperm or eggs.The research team consisted of scientists from Australia's Murdoch Institute as well as the Broad Institute in the U.S.In Leigh syndrome, infants are born apparently healthy only to develop movement and breathing disorders that worsen over time, often leading to death by the age of three. The problem is that the mitochondria responsible for powering their cells cannot keep up with the demand for energy in their developing brains.

BEIJING, Sept. 21 (Xinhuanet) -- China will launch an unmanned module next week, paving the way for a planned space station, a spokesman for the space program said on Tuesday.Tiangong-1, or "Heavenly Palace 1", will blast off from Jiuquan Satellite Launch Center in Gansu province between Sept 27 and 30, the spokesman said.The 8.5-ton module, and the Long March II-F rocket that will carry it skyward, were positioned onto the launch pad on Tuesday, signaling that the project has entered the final preparation stage."Scientists will conduct final tests in the next few days before injecting propellants for the launch," Cui Jijun, director of the Jiuquan Satellite Launch Center, said.The program spokesman said that Tiangong-1 will serve as "a target spacecraft" for rendezvous and docking experiments.It will also work as "a platform to test long-term unmanned and short-term manned operations", he said.Technical and medical experiments will provide crucial data ahead of the building of the space station (scheduled for 2020).Three rendezvous and docking experiments will be conducted.An unmanned Shenzhou-VIII craft will be launched later this year to dock with Tiangong-1. In 2012, Shenzhou IX and Shenzhou X will blast off to complete at least one manned docking.Jiao Weixin, a space scientist at Peking University, said that rendezvous and docking - vital maneuvers for manned programs - are hard to master."Rendezvous and docking are difficult because it is like asking two racing cars to keep a distance of 1 meter between them," he said.The mission requires two craft, traveling at speeds of 28,000 km/h, to enter the same orbit and connect with precision, he said.The China Manned Space Engineering Office rescheduled the launch of Tiangong-1 after the failed launch of an experimental orbiter last month.The spokesman said that the carrier rocket to blast off with Tiangong-1 atop has been modified.Only the United States and Russia have mastered rendezvous and docking technology, said Pang Zhihao, deputy editor-in-chief of the magazine Space International.Spacecraft developed by Europe and Japan have utilized US and Russian technology to dock with the International Space Station, he added.
