SAN FRANCISCO, April 22 (Xinhua) -- Apple and Google collect smartphone users' location information as part of their race to build massive databases, The Wall Street Journal reported on Friday after analyzing data and documents.According to the report, security analysts with the newspaper found that Apple's iPhone and smartphones running Google's Android operating system regularly transmit users' locations back to the two companies respectively, which is part of their race to build databases capable of pinpointing people's locations via smartphones.A report by research firm Gartner indicated that the market for location-based services is expected to rise to 8.3 billion U.S. dollars in 2014 from the current 2.9 billion dollars.In the case of Google, a security analyst with The Wall Street Journal said an HTC Android phone collected name, location, signal strength of any nearby Wi-Fi networks, and a unique phone identifier every few seconds and transmitted the data to Google at least several times an hour."All location sharing on Android is opt-in by the user," Google said in a statement to technology blog site All Things Digital, in response to the concern that how Android system uses location information."We provide users with notice and control over the collection, sharing and use of location in order to provide a better mobile experience on Android devices. Any location data that is sent back to Google location servers is anonymous and is not tied or traceable to a specific user," said the statement.Worries on the iPhone tracking issue surfaced on Wednesday after two British researchers announced at a technology conference in California that iPhone has been collecting users' location information and storing the data for extended periods of time.The researchers said starting on June 21 2010, after the release of iOS 4 mobile operating system, iPhones began logging and storing location information in a file, which shows the users' latitude and longitude and is timestamped to the second. They noted the information is not encrypted on the phone or on the iPhone backups made by iTunes and the file is also persistent, transferring itself to a new iOS device when the old one is replaced.They added they had no evidence that the file was being transmitted to Apple.On Thursday, U.S. congressman Edward Markey reacted angrily to the news in a letter to Apple CEO Steve Jobs, which is posted on Markey's official website.Markey asked Jobs to make a response within 15 business days or no later than May 12, saying "Apple needs to safeguard personal location information of its users to ensure that an iPhone doesn't become an iTrack."Apple has made no comment on the issue so far, but a letter it sent to U.S. Congress last July came under spotlight. In the letter, Apple said it collects Wi-Fi and GPS information when the phone is searching for a cellular connection and gathers the data to help build a "database with known location information."

BEIJING, April 14 (Xinhuanet) -- The discovery of a sharp-toothed dinosaur fossil in New Mexico, the United States, may bridge a gap in the evolution of the species, researchers said in Wednesday's journal Proceedings of the Royal Society B.Researchers from the Smithsonian Institution unearthed the dinosaur skull and neck vertebrae in Abiquiu, New Mexico, where it had remained buried for around 230 million years. The short snout and slanting front teeth of the find — Daemonosaurus chauliodus — had never before been seen in a Triassic era dinosaur, said Hans-Dieter Sues of the Smithsonian's National Museum of Natural History.Sues, curator of vertebrate paleontology at the museum, said the discovery helps fill the evolutionary gap between the dinosaurs that lived in what is now Argentina and Brazil about 230 million years ago and the later theropods like the famous Tyrannosaurus rex."Various features of the skull and neck in Daemonosaurus indicate that it was intermediate between the earliest known predatory dinosaurs from South America and more advanced theropod dinosaurs," said Sues."One such feature is the presence of cavities on some of the neck vertebrae related to the structure of the respiratory system," he added.The discovery suggests that there is still much to be learned about the early evolution of dinosaurs."The continued exploration of even well-studied regions like the American Southwest will still yield remarkable new fossil finds," Sues said.

BEIJING, Feb. 8 (Xinhuanet) -- China's railroads and highways will see their busiest day of the Spring Festival holiday on Tuesday when the number of travelers returning to major cities hits its peak, just as a cold snap sweeps across much of the country, the ministries of railways and transport said on Monday.The Ministry of Railways said on its website that there had been a sharp rise in the number of travelers leaving smaller cities on Monday bound for such places as Beijing, Shanghai and Guangzhou.The ministry said the number of people on the move on Tuesday is likely to make the day the Spring Festival travel peak.The nation's roads are also likely to be at their Spring Festival maximum on Tuesday and Wednesday, the Ministry of Transport reported on Monday on its official website.The National Meteorological Center (NMC) added on Monday that a moderate cold snap was expected on Tuesday, causing temperatures to fall by between four and six degrees in most parts of China.The weather pattern will bring widespread rain and snow to the southern part of China from Wednesday to Friday, the NMC said.The Ministry of Railways said on its website that it has asked its local branches to be prepared for the upcoming icy weather.Meanwhile, the local authorities in big cities have been bracing for the arrival of massive numbers of travelers as the Spring Festival holiday winds down.In Shanghai, tens of thousands of public transportation workers cut their holidays short and put 27 additional bus lines on the road to meet demand as passengers began arriving in large numbers at the city's railway stations.The influx began on Saturday night, according to local newspaper Wenhui Daily.On Sunday, the pressure intensified on the Qinghai-Tibet railway, two days earlier than expected.As a result, the railway company organized additional workers to facilitate the flow of people through Xining Railway Station in Northwest China's Qinghai province.Many volunteers have also been pitching in to help keep people moving and have offered to do various jobs at stations, such as helping people buy tickets and assisting them in checking their travel schedules.Among them, Liu Chen, a student from the Guangzhou-based Zhongkai University of Agriculture and Engineering, has been helping people at Guangzhou Railway Station by carrying their bags."One day, I helped more than 70 passengers with their luggage and, after all of them got on the trains, it felt like my legs were almost paralyzed," he said.The Hohhot railway bureau in North China's Inner Mongolia autonomous region said it is expecting so many extra passengers that it has scheduled four additional trains for lines to Chongqing and Beijing.With so many people scrambling to get back from family gatherings and holidays to their jobs in China's big cities, the rush to buy tickets has been phenomenal. Tickets for trains that will leave Nanjing on Tuesday for Beijing, Guangzhou, Harbin and Changchun had virtually all gone on Monday morning, Jiangsu's Yangtse Evening Post reported.On Sunday, the fourth day of Spring Festival, the country's railways carried a total of 5.3 million travelers, which was up by 12.8 percent on the 4.7 million who rode the rails a day earlier, according to the Ministry of Railways.Another 38.6 million travelers made Spring Festival trips on Sunday on buses and ships, according to the Ministry of Transport.The traditional chunyun period, or Spring Festival travel season, runs for 40 days and is calculated in two phases: 15 days before Spring Festival Eve and 25 days after it, as stipulated by the central government.China's railways moved about 77.3 million passengers during the first 15-day period, which ran from Jan 19 to Feb 2, the Ministry of Railways reported.

BEIJING, Jan. 23 (Xinhua) -- Chinese President Hu Jintao's state visit to the United States, during which he reached important consensus with U.S. President Barack Obama on building a cooperative China-U.S. partnership based on mutual respect and mutual benefit, has been closely followed by world media.The visit has drawn "unprecedented" world attention, said Gu Xuewu, director of the Center for Global Studies at the University of Bonn.NEW CHAPTER IN DEVELOPMENT OF CHINA-U.S. TIESCommenting on Hu's visit, which occurred at the beginning of the second decade of the 21st century, Professor Severino Cabral, director of Brazil's China and Asia-Pacific Research Institute, said the visit opened a new epoch for China-U.S. relations.The resumption of dialogue between the world's two major economies, which itself is a significant event, would exert great influence on the new world agenda, and hopefully help eliminate the residual cold war mentality and take bilateral relations to a new era, he said.Chen Kang, professor at Lee Kuan Yew School of Public Policy at the National University of Singapore, said that the joint statement issued by the two sides during Hu's stay -- built upon bilateral efforts to establish a cooperative partnership based on mutual respect and mutual benefit -- is a clear reflection of the two countries' resolution and pragmatic attitude in jointly meeting global challenges.China Press USA, a New York-based Chinese language newspaper, said in an editorial that the two countries' commitment to building an all-round and mutually beneficial, win-win economic partnership, as put in their joint statement, is the greatest achievement that comes out of the meeting between the leaders of the two countries in the economic sphere.Nouvelles D'Europe, a major Chinese language newspaper in France, said in an editorial that Hu's visit yielded fruitful results which are indispensable to world peace and development.In their joint statement, the two countries for the first time defined that China-U.S. partnership is based on mutual respect and mutual benefit. Stable China-U.S. relations contribute to world stability, and a win-win scenario between China and the United States is conducive to a scenario of multi-party-win in a multipolar world, it said.International Daily News, an Indonesian newspaper, said that Hu's visit achieved a historic breakthrough. Their joint statement signaled a new chapter in their "cooperative partnership based on mutual respect and mutual benefit," and Asia is hailing the new orientation of bilateral ties and achievement set up by the leaders of the two countries.

WASHINGTON, April 11 (Xinhua) -- In the first clinical trial of gene therapy for treatment of intractable pain, U.S. researchers from the University of Michigan's Department of Neurology observed that the treatment appears to be able to provide substantial pain relief.In a study published online in the Annals of Neurology and seen on Monday, the researchers showed that the novel agent NP2 is safe and well-tolerated. In addition, measures of pain in the treated patients suggested that NP2 may provide a substantial analgesic effect.NP2 is a gene transfer vector that expresses the naturally- occurring opioid peptide enkephalin. In preclinical work in animals, David Fink, chair of the Department of Neurology, and his coworkers had demonstrated that injection of NP2 into the skin reduces pain in models of pain caused by nerve damage, inflammation or cancer.In the clinical trial, 10 patients with unrelenting pain caused by cancer were injected with the gene transfer agent in the area of skin related to the location of pain."The concept underlying this therapeutic approach is that injection of NP2 into the skin results in uptake into the nervous system and the production and release of a pain-relieving chemical in a controlled site in the pain pathway," says Fink. "In the study, patients who received the low dose of vector showed little reduction in pain; patients receiving the higher doses showed a greater than 80 percent reduction in pain over the course of four weeks following treatment."Fink's laboratory has been working on the use of modified herpes simplex virus-based vectors that are taken up by sensory nerves following skin injection to develop therapies for diseases of the nervous system for more than 20 years. Patents related to this technology have been exclusively licensed by Diamyd Medical, a publicly-traded Swedish biotechnology company that sponsored the trial, and the human-grade vector NP2 was produced by Diamyd, Inc, the U.S. subsidiary of Diamyd Medical.A phase 2 trial to compare NP2 to a placebo control has already been initiated under sponsorship from Diamyd.
