BEIJING, Nov. 10 (Xinhuanet) -- Awareness in three vegetative patients were detected in a portable electrode test, a new study shows. If replicated, the method may change standards in treating such patients.The new study, published online in the journal The Lancet Wednesday, was reported to be the first to detect signs of awareness in patients living in the unresponsive state through more accessible electroencephalogram (EEG) machine.The EEG is a portable and more affordable technique than Magnetic Resonance Imaging (MRI) scanner, but it is as effective as the MRI to diagnose patients in the vegetative state, according to the research team led by Damian Cruse and Adrian M. Owen of the University of Western Ontario.In the research test, the team hooked 16 previously determined to be vegetative patients to EEG machines and gave simple instructions to them like moving their fingers and toes.The machines show that the patterns in the premotor cortex, the area of the brain that plans and prepares movements, in three of 16 patients were exactly the same as those of healthy volunteers.While the patients were able to follow simple instructions, they were not able to make their own decisions about their state, the researchers said.

JIUQUAN/BEIJING, Nov. 1 (Xinhua) -- Commander-in-chief of China's manned space program Chang Wanquan announced early Tuesday that the launch of Shenzhou-8 unmanned spacecraft was successful.The spacecraft was sent into the designated orbit after the blastoff at 5:58 a.m. from the Jiuquan Satellite Launch Center in northwest Gobi desert, carried by an upgraded Long March-2F rocket.It is heading for rendezvous with Tiangong-1, or "the Heavenly Palace" that was put into space on Sept. 29 for the country's first space docking.The move, if successful, will pave the way for China to operate a permanent space station around 2020 and make the nation the world's third to do so.The combined photo taken on Nov. 1, 2011 shows the blast-off of a modified model of the Long March CZ-2F rocket carrying the unmanned spacecraft Shenzhou-8 at the Jiuquan Satellite Launch Center in northwest China's Gansu Province. Commander-in-chief of China's manned space program Chang Wanquan announced that the launch of the spacecraft was successful.Chinese Vice Premier Zhang Dejiang viewed the launch at the Jiuquan center. The launch was also observed on site by senior officials from the European Space Agency and the German Aerospace Center.The docking is scheduled to occur within two days after the launch of Shenzhou-8 and at a height of 343 km above the Earth's surface. It will return to the Earth after two docking tryouts.Chinese and German scientists will conduct 17 life science space experiments on the Chinese spacecraft Shenzhou-8, Wu Ping, spokeswoman for China's manned space program, said Monday.To ensure the success of the mission, Chinese space engineers have made "considerable modifications" on Shenzhou-8 to previous versions of the spacecraft.Shenzhou-8, with a length of nine meters and a maximum diameter of 2.8 meters, has a liftoff weight of 8.082 tonnes."More than half of the 600 or so sets of equipment have been modified, while newly designed devices account for about 15 percent of the total," Wu said.The modifications were mainly aimed at arming the spacecraft with automatic and manual rendezvous and docking capacities, and enhancing the vehicle's performance, safety and reliability, Wu said."After the improvements, the spacecraft will be able to connect with the target spacecraft Tiangong-1 for 180 days," Wu said.The unmanned spacecraft is also equipped with devices for recording real images and mechanical parameters during its flight, to test the space docking before a manned attempt.Once China has mastered the technologies of rendezvous and docking, it will be equipped with the basic technologies and capacity required for building a space station, said Zhou Jianping, chief designer of China's manned space program.Tuesday's mission will be followed by launches of spaceships Shenzhou-9 and -10 in 2012, which are also expected to dock with Tiangong-1. "At least one mission of the two will be manned," Wu said.The crew members, including probably two female astronauts, have already been selected for the possible manual space docking mission in 2012 and are being trained for manual docking skills.The space docking tests and experiments will provide crucial experience of China's construction of a 60-tonne permanent manned space station around 2020 when Chinese astronauts are expected to operate more research projects in space."It will make it possible for China to carry out space exploration of a larger scale," Zhou said.

BEIJING, Nov. 7 (Xinhuanet) -- A huge asteroid will pass closer to Earth than the moon on Tuesday, but experts say there is no cause for alarm.Asteroid 2005 YU 55 will pass about 300-thousand kilometers from the earth. The giant space rock is about 400 meters in diameter. The close encounter will occur at 23:28 Greenwich Mean Time. Computer models showing the asteroid’s path for the next 100 years show there is no chance it will hit Earth during that time.Previous studies show the asteroid is what is called a C-type asteroid that is likely made of carbon-based materials and some silicate rock.

BEIJING, Nov. 1 (Xinhua) -- The ministers of Brazil, South Africa, India and China (BASIC) in a Tuesday joint statement urged developed nations to fulfill their commitments and provide funds and technology to help developing nations tackle climate change.Developed nations should honor their commitments, made at the Copenhagen climate change conference in 2009, to provide 100 billion U.S. dollars annually by 2020 and ensure that there will be no funding gaps from 2013 to 2020, according to the statement.Developed nations should also fulfill their pledge to offer 30 billion U.S. dollars in "fast-start funding" to developing nations in order to help them address climate change, the statement said.The ministers agreed that the coming Durban climate change conference should achieve a "comprehensive, fair and balanced outcome" under the principle of common but differentiated responsibility.They called on the conference to clearly establish the second commitment period under the Kyoto Protocol, during which developed country parties to the Kyoto Protocol should undertake quantified emission reduction commitments.The Kyoto Protocol is the cornerstone of climate change and its second commitment period is an essential priority for the success of the Durban conference, according to the statement.H The joint statement was issued following a two-day meeting of ministers from the four nations, also known as the ninth BASIC Ministerial Meeting on Climate Change, a mechanism through which the four countries and other developing countries coordinate their efforts in climate change.Representatives of Group 77 countries, island countries and the Arab League also attended the meeting.The Durban conference is scheduled for November. The focus of the conference is expected to be the extension of the Kyoto Protocol and acquiring a commitment from developed countries for the protocol's next period.The Kyoto Protocol, an international agreement linked to the United Nations Framework Convention on Climate Change, sets binding targets for 37 industrialized countries and the European community for reducing greenhouse gas emissions from 2008 to 2012.

OTTAWA, Oct. 26 (Xinhua) -- Canadians are working about three years longer before retirement than they were in the 1990s, and have a longer life in retirement, an official study said Wednesday.Statistics Canada, the federal statistics agency, reports that Canada' s men and women, who don't face compulsory retirement, are increasingly choosing to delay retirement, as part of a long-term trend that has begun before the recent recession.The trend of later retirement dates back to the mid-1990s, when a 50-year-old employee could expect to work another 12.5 years before retiring from the daily grind.Today, that same 50-year-old worker could expect another 16 years of employment.The study says that 34 percent of Canadians aged 55 and older were employed in 2010, compared to just 22 percent in 1996.A longer working life would unnecessarily imply a shorter life in retirement due to increased life expectancy, the study says.The study notes that men and women leaving the work force today are spending as much time in their post-career life as many of their predecessors did.For example, between 1977 and 1994, the typical retirement length for a man in Canada rose from 11.2 to 15.4 years; as of 2008, it was 15 years.For women, the average retirement length similarly rose from 16.4 to 20.6 years between 1977 and 1996; as of 2008, it was 19 years.From another point of observation, 50-year-old men can expect to spend 48 percent of their remaining years of life in retirement in 2008,compared with 45 percent in 1977.In 2008, 50-year-old women could expect to spend 55 percent of their remaining years of life in retirement, nearly identical to the proportion in 1977.
