ISLAMABAD, Sept. 11 (Xinhua) -- Chinese ambassador to Pakistan declared on Sunday that the Chinese government will provide an emergency humanitarian aid worth 30 million RMB (4.7 million U.S. dollars) to Pakistan to help its relief efforts.In light of the immense damages caused by the floods in some parts of Pakistan, Chinese Ambassador to Pakistan Liu Jian called on Pakistani Foreign Minister Hina Rabbani Khar on Sunday to express sympathy and solidarity of the Chinese people toward Pakistani people and declared that the Chinese government will provide the emergency humanitarian aid.Diplomats and staff of the Chinese Embassy in Islamabad have recently voluntarily donated 600,000 rupee (about 6860 U.S. dollars) to the people who hit by the floods. The Chinese ambassador handed over the donation to Pakistani side on Sept. 8.On Sept. 9, Chinese Foreign Minister Yang Jiechi sent a message to his Pakistani counterpart H.E. Hina Rabbani Khar, expressing his profound condolence to the victims and sincere sympathy to the affected people of the floods.The Chinese foreign minister said that China, as Pakistan's close friend, feels as much pain as Pakistan does and is ready to provide help to the best of its ability, in line with Pakistan's needs. He is convinced that the Pakistani people will definitely prevail over the natural disaster and rebuild their homes at an early date.

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.

WASHINGTON, July 15 (Xinhua) -- Researchers at Mount Sinai School of Medicine have found that grape seed polyphenols -- a natural antioxidant -- may help prevent the development or delay the progression of Alzheimer's disease.The research, led by Giulio Pasinetti, was published online Friday in the Journal of Alzheimer's Disease, which causes brain changes that gradually get worse.This is the first study to evaluate the ability of grape- derived polyphenols to prevent the generation of a specific form of amyloid (A) peptide, a substance in the brain long known to cause the neurotoxicity associated with Alzheimer's disease.In partnership with a team at the University of Minnesota, Pasinetti and collaborators administered grape seed polyphenolic extracts to mice genetically determined to develop memory deficits and A neurotoxins similar to those found in Alzheimer's disease. They found that the brain content of the A*56, a specific form of A previously implicated in the promotion of Alzheimer's disease memory loss, was substantially reduced after treatment.Previous studies suggest that increased consumption of grape- derived polyphenols, whose content, for example, is very high in red wine, may protect against cognitive decline in Alzheimer's. This new finding corroborates those theories."Since naturally occurring polyphenols are also generally commercially available as nutritional supplements and have negligible adverse events even after prolonged periods of treatment, this new finding holds significant promise as a preventive method or treatment, and is being tested in translational studies in Alzheimer's disease patients," said Pasinetti.In Alzheimer's disease, brain cells degenerate and die, causing a steady decline in memory and mental function.

BEIJING, Sept. 23 (Xinhua) -- A defunct U.S. satellite is expected to crash down to Earth Friday, with nobody knowing where or when exactly it will hit. This was avoidable, a Chinese expert said Thursday.Pang Zhihao, a researcher from the Chinese Research Institute of Space Technology, told Xinhua that the crash could have been avoided had the satellite been put into a higher orbit, or manipulated to drop in the South Pacific when it had abundant fuel. It would pose no threat to Earth if these measures had been taken.NASA's tumbling, 5,900 kg Upper Atmosphere Research Satellite, or UARS, is the first of such man-made space vehicles that have been launched into outer space according to the agency's Mission to Planet Earth. The mission was launched in the 1990s.The mission is designed to provide data for better understanding Earth's upper atmosphere and the effects of natural and human interactions on the atmosphere.The satellite was deactivated in 2005 as it ran out of fuel and was left orbiting Earth like a big piece of space junk.There are other cases of defunct satellites. The European Space Agency said earlier its observation satellite ERS-2 has run out of fuel and is deorbiting. It would therefore also crash sooner or later.Pang said all countries which are operating space vehicles should take care of their own spacecrafts so that they won't pose any danger.The expert also said that the public need not worry too much.Pang said most spacecrafts will be incinerated upon re-entering Earth's atmosphere, and the debris will mostly likely fall into the ocean or hit an uninhabited area. In addition, a debris tracker is able to give a comparatively accurate prediction where the craft will fall about two hours before it hits Earth, giving residents, if there are any, time to evacuate.He added that there are several ways to minimize the threat of decommissioned spacecrafts, like putting them into higher orbits and crashing them into designated waters.Scientific progress would possibly bring about more ways of dealing with tumbling satellites. Scientists have already been trying to build spacecrafts with degradable materials so that they can self-destruct when re-entering Earth's atmosphere.

BERLIN, June 9 (Xinhua) -- A 57-year-old man died of E. coli infection in Germany's Frankfurt Thursday, pushing the death toll from the bacteria to 30.The man had traveled with his wife to the city of Hamburg, an epicenter of the outbreak, Frankfurt authority said.Another two deaths were reported in the state of Lower Saxony, including a 68-year-old man and a 20-year-old woman, while more than 2,800 people in 14 countries have been infected since the deadly E. coli outbroke.German researchers detected again the deadly strain o104 of E. coli on the scraps of cucumbers in a dustbin in the eastern city of Magdeburg in the state Saxony-Anhalt on Wednesday.German health minister Daniel Bahr expressed his cautious hope for the disease on Wednesday as the number of new infection is clearly going down.But he also admitted there will be new cases and more deaths have to be expected, as Germany's national disease control centre, the Robert Koch Institute reported more than 300 infection in Germany on the same day.The Robert Koch Institute also noticed the declining trend in new cases but it was not clear whether this was caused by people staying away from vegetables or the outbreak was truly waning.
