NANJING, Dec. 8 (Xinhua) -- Chinese stargazers will have their best view of a total lunar eclipse in 10 years on Saturday if weather permits, the Zijinshan Astronomical Observatory under the Chinese Academy of Sciences (CAS) said Thursday.Wang Sichao, a research fellow with the observatory, said during the total eclipse, the full moon will not completely disappear from the Earth's shadow, but will take on a brilliant bronze color.He said the eclipse will be the best one seen in China since the last one occurred on Jan. 10, 2001."Theoretically, viewers can observe the eclipse from nearly everywhere in the country on Saturday," said the astronomer.He said the eclipse, the second this year, will last for 51 minutes. It will start at 8:45 p.m. and reach its climax at 10:06 p.m.Wang said Chinese viewers will have to wait until Oct. 8, 2014 to see the next total lunar eclipse.

WASHINGTON, Dec. 12 (Xinhua) -- British scientists have discovered a new way to target cancer through manipulating a master switch responsible for cancer cell growth. The findings, published Monday in the U.S. journal Cancer Cell, reveal how cancer cells grow faster by producing their own blood vessels.Cancer cells gain the nutrients they need by producing proteins that make blood vessels grow, helping deliver oxygen and sugars to the tumor. These proteins are vascular growth factors like VEGF -- the target for the anti-cancer drug Avastin. Making these proteins requires the slotting together of different parts of genes, a process called splicing.Scientists at the University of West England and the University of Bristol discovered that mutations in one specific cancer gene can control how splicing is balanced, allowing a master switch in the cell to be turned on. This master switch of splicing makes cancer cells grow faster, and blood vessels to grow more quickly, as they alter how VEGFs are put together.In experimental models, the researchers found that by using new drugs that block this master switch they prevented blood vessel growth and stopped the growth of cancers."The research clearly demonstrates that it may be possible to block tumor growth by targeting and manipulating alternative splicing in patients, adding to the increasingly wide armory of potential anti-cancer therapies," the authors said.

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 is successful.The spacecraft was successfully sent into the designated orbit after the blastoff at 5:58 a.m. at the Jiuquan Satellite Launch Center in northwestern desert area, carried by an upgraded Long March-2F rocket.It is heading to rendezvous with the Tiangong-1, or "Heavenly Palace-1" that was put into space on Sept. 29 for the country's first space docking.The docking, 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 launch was attended by Chinese Vice Premier Zhang Dejiang. It was also observed by senior experts from the European Space Agency and the German Aerospace Center at the launch site.The docking will happen within two days after the launch of the Shenzhou-8 at a height of 343 km above Earth's surface. The spacecraft will return to Earth after two docking operations.

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.

JINAN, Oct. 24 (Xinhua) -- Chinese scientists have made a breakthrough that could lead to more effective treatments for leprosy.A team from Shandong Provincial Institute of Dermatology and Venereology in east China has identified two new risk variants near IL23R and RAB 32 genes that are responsible for the disease, according to a report published online Monday in the scientific journal Nature Genetics.Knowing that the two gene variants influence susceptibility to leprosy could allow doctors to diagnose the disease in sufferers earlier in its outset, as well as to develop new treatments. A genetic database could now be built up to predict those people particularly susceptible to leprosy, said Zhang Furen, the leader of the research team.The study involved more than 10,000 samples being taken from leprosy sufferers and healthy test subjects and analysed.Leprosy is a chronic nerve-killing disease that leads to problems with patients' skin, feet, hands, legs and eyes. More than 200,000 newly-contracted leprosy cases are reported worldwide every year, and China has around one tenth of the world's sufferers.
