STOCKHOLM, Jan. 26 (Xinhua) -- China's railway network, already the world's longest, is developing at record high speed and is to be doubled soon, Swedish daily Svenska Dagbladet reported on Wednesday."China's goal is to connect all important cities with railway lines," the report said.Collaborating with German Siemens, Japanese Kawasaki and Bombardier both in Canada and Sweden, China has built its own high-speed train CRH380A that can reach 486 kilometers per hour, cutting the journey between Beijing and Shanghai in half to about 4 hours.Construction of the high-speed railway network will also cover inland China, the report said. It aims to encourage more investment to move from coastal areas to inland China and ultimately raise the living standards in those regions.Within the next five years, a total of 3.5 trillion yuan (over 500 billion U.S. dollars) will be invested in high-speed track construction and train manufacturing, averaging at about 700 billion yuan (over 100 billion dollars) each year.Swedish companies such as Atlas Copco, SKF and Trelleborg have participated in China's railway and high-speed train development, according to the report.Hans Rosling, a development expert and also professor at Karolinska Institutet in Sweden, was quoted as saying that the construction of the high-speed railway network will bring about "good economy, good education, good medical care, better and longer life, all good things."

HAIKOU, Jan. 28 (Xinhua) -- China's aviation authorities on Friday started to allow helicopters to fly in low-altitude airspace over the tourist island of Hainan on a trial basis for the first time. The aim is to eventually open a part of the country's tightly-controlled airspace to private aircraft.Four helicopters were manned by eight pilots from Shanghai-based Zhengyang Investment Group, a leading domestic firm in the general aviation industry. They are expected to conduct test flights in the sky, 1,000 meters above the ground in Hainan in the next two months.The flight test will collect data for low-altitude flying and test the ground control system's response to emergencies, said Zou Jianming, chairman of Zhengyang Investment Group.Hainan is the first place in China to conduct test flights of private aircraft in low-altitude airspace, said Jiang Sixian, deputy governor of the province. Domestic and foreign firms are both welcome to invest in Hainan's general aviation sector to develop world-class tourism here.China's low-altitude airspace is controlled by the Air Force and the Civil Aviation Administration of China (CAAC). Every private aircraft flight needs approval, and the procedure can take from one day up to a week.But last November, the State Council and the Central Military Commission said that part of the low-altitude airspace would be opened to promote the country's general aviation sector, including the purchase and use of private planes.General aviation refers to the part of the aviation industry that excludes flights for military, law enforcement and public transport. China has only 900 aircraft, 80 airports and fewer than 10,000 pilots in the general aviation segment.The market for general aviation in China is valued at only 13 billion yuan (1.98 billion U.S. dollars) but is expected to grow by 15 percent annually until 2020, Hainan aviation officials said.

SAN FRANCISCO, April 22 (Xinhua) - Amazon's web-services disruption issues have not been completely resolved Friday morning, as some websites still in slow recovery.Amazon said in an update early Friday that meaningful progress has been made and is expected to continue over the next few hours.Reddit, a social news website, said on its homepage that "we are slowly getting our capacity back," and users may be able to log in if lucky. Some sites appeared to have recovered, including location-based social networking site Foursquare and HootSuite, an online brand management and social websites monitoring service.Amazon has not released the number of companies which have been disrupted by the outage and when the web-services will fully recover.The outage highlights risks of relying on public cloud service. Security and reliability have been experts' concerns on public could web-hosting service. Many Internet startups have been relying on the service to bring their costs down.Elastic Compute Cloud (EC2) is a central part of Amazon's cloud computing platform Amazon Web Services. It allows users to rent virtual computers on which to run their own computer applications. The European Space Agency, PBS and Ericsson are all among its cloud service customers.According to Amazon's Service Health Dashboard, errors began at 1:41 a.m. PDT Thursday in its datacenter in northern Virginia, saying "instance connectivity, latency and error rates."

HARBIN, March 2 (Xinhua) -- A therapeutic apparatus to treat Parkinson's disease has been developed in northeast China's Heilongjiang Province, according to the provincial science and technology department. It is a worldwide breakthrough in treating the disease with transcranial magnetic stimulation, concluded an expert panel with the Heilongjiang Provincial Department of Science and Technology.The team said it came to the conclusion after evaluating technical documents and clinical test results Monday.This is the first time that transcranial magnetic stimulation has been adopted to treat Parkinson's disease, said Sun Zuodong, chairman of Aobo Medicine Apparatus Co., Ltd. (AMA), the developer based in the provincial capital Harbin.Transcranial magnetic stimulation is a noninvasive method which causes depolarization in the brains' neurons so as to restore the functions of brain nerves.The apparatus consists of three parts, namely brain wave stimulator, field effect cap and multiplier, said Sun.Clinical tests over more than 100 patients showed that the apparatus had a 70 percent success rate in reducing the disease's symptoms, according to Wang Aili, planning manager of AMA.The new equipment will help generation of dopamine, the reduction of which within the brain caused the disease, said Wang Weixiang, a consulting doctor with the Heilongjiang Provincial Rehabilitation Hospital.Parkinson's disease is a disorder of the neural system, which leads to limb tremors and difficulty in walking and other movements.China has 2 million patients suffering from Parkinson's disease, mostly people over the age of 50, and the number is increasing by 100,000 annually, said Dr. Wang.
