BEIJING, Sept. 27 (Xinhuanet) -- Last-minute preparations for the launch of the Tiangong-1 spacecraft began at the Jiuquan Satellite Launch Center on Monday, meaning the vehicle can soon embark on a mission that will eventually have it dock with a spaceship, according to the center.That feat, if carried out successfully, will mark the completion of China's first rendezvous and docking mission.At the launch site on Monday afternoon, crews were putting in place pipes and cables that will be used to inject fuel into the rocket that will carry Tiangong-1 into outer space.Without complications from the weather or other causes, the Long March II-F rocket will lift off from the launch center on Thursday or Friday, taking the Tiangong-1 with it, according to the Xinhua News Agency.Despite the preparations, space experts said carrying out the plan still comes with many risks. They explained that the spacecraft and much of the other equipment being used is new and has not been tried on an actual mission."Tiangong-1 is a brand new spacecraft designed by China and is bigger and heavier than the Shenzhou spaceships China had developed as a means of transporting astronauts from the Earth to space," said Yang Hong, chief designer of Tiangong-1.In a vertical position, the Tiangong-1 looks like a cigar standing 10.4 meter tall, a height equal to that of a three-story building. It weighs 8.5 tons and has a maximum diameter of 3.35 meters, a dimension shared by its launch vehicle, he said.In comparison, the Shenzhou spaceship stands shorter, at nearly 9 meters, is slimmer, having a diameter of less than 3 meters, and weighs less.In another difference, the Tiangong-1 is composed of two modules rather than the three that had made up the Shenzhou spaceship. Of the Tiangong-1's two primary components, one is an experimental module that contains a place that astronauts can live and work in on future missions. It is also equipped with a docking port.The other chief component, a resource module, will provide the craft with power.Astronauts on Tiangong-1 will have 15 cubic meters of space to move in, "much more than they had in the Shenzhou spaceship", Yang said.Inside the spacecraft are two sleeping sections with adjustable lighting systems, exercise equipment, entertainment systems and visual communication devices, he said.Hou Xiangyang, who helped design Tiangong-1, said: "The sleeping section is big enough for a 1.8-meter-tall man to sleep in. An astronaut can adjust the light as he likes."In space, Tiangong-1 will fly in a horizontal position. A paint scheme inside will help the astronauts aboard maintain their sense of direction; the module's inner walls will be in two colors, one commonly associated with the sky and one with the ground."This will help astronauts avoid feeling as if they are standing upside down in the microgravity environment," he said.Yang said the Tiangong-1 spacecraft is expected to stay in orbit for two years and rendezvous and dock with three different spaceships. Beyond the Shenzhou VIII, ships named Shenzhou IX and Shenzhou X will embark on similar missions; at least one of the two is to be manned.Before astronauts climb on board Tiangong-1, the conditions inside its experimental module will be adjusted to ensure they can live in an environment that contains enough oxygen, moisture and heat to be safe.Tiangong-1 was originally scheduled to be launched into a low orbit around the Earth between Sept 27 and 30. The earlier days were removed as possible launch dates, though, after forecasters predicted a cold air mass would move into the area containing the Jiuquan Satellite Launch Center.To ensure the spacecraft and Long March II-F carrier rocket are ready for launch, a full ground simulation was conducted on Sunday afternoon.

SAN FRANCISCO, June 20 (Xinhua) -- Google and the British Library announced Monday that the Internet search giant will digitize 250,000 out-of-copyright books from the library's collections, making up to 40 million pages from 1700 to 1870 available to the public online.In a joint statement, the British Library and Google said they will work in partnership over the coming years to deliver the content free through Google Books and the library's website, and full text search, download and reading will be available. Google will cover all digitization costs.The project is going to cover a huge range of printed books, pamphlets and periodicals dated 1700 to 1870, a period of political and technological turmoil, from the Industrial Revolution to the French Revolution, from the introduction of the income tax in Britain and the invention of the telegraph and railway.It will include material in a variety of major European languages and will focus on books that are not yet freely available in digital form online, said the statement.Since December 2004, Google has announced partnership with some 40 high-profile university and public libraries, planning to digitize and make available some 15 million volumes within a decade through Google Books service.The project has triggered controversy as publisher and author associations oppose the plan to put copyrighted titles online in a class action lawsuit.

BEIJING, July 26 (Xinhuanet) -- The breast cancer is more deadly to black women than to whites, a new study found.This finding was published online Monday on the "Journal of Clinical Oncology" in the United States.The study was done by the City of Hope, a Comprehensive Cancer Center in Duarte, California.The researchers collected data from more than 4,500 U.S. women in the 35-64 age group who were diagnosed with breast cancer.With the passing of  more than eight years, the researchers found the black women have a three times death rate than white women, after taking obesity and other diseases into account."It’s been long known that breast cancer in African-American women is a far less common disease than in white women. But when it occurs, it seems to be more aggressive and harder to treat," said Dr. Lisa Carey of the University of North Carolina’s Lineberger Comprehensive Cancer Center.But why the situations varied by race, scientists are still exploring the answer.

BEIJING, Sept. 1 (Xinhua) -- Medicine prices at public clinics have been notably reduced thanks to a policy that promotes basic medicine, an office of the State Council said Thursday.Current price levels of basic medicine used by government-funded township hospitals and community clinics have been reduced an average of 25 percent from the levels two years ago when the policy started, according to a statement from the State Council office in charge of reforming the country's healthcare program.China has introduced a state list of basic medicine used by government-funded township hospitals and community clinics, which includes roughly 300 types of commonly-used Western and traditional Chinese medicine.Provincial governments will purchase basic medicine through public bidding and distribute them to local clinics.These clinics must not raise the prices of listed medicine and in return, the government will provide them with subsidies.The policy has been implemented at all township and community clinics in all the 31 provinces, municipalities and autonomous regions in the Chinese mainland, the statement said. 

LOS ANGELES, June 23 (Xinhua) -- The sun and its inner planets may have formed differently than previously thought, NASA's Jet Propulsion Laboratory (JPL) said on Thursday.Data revealed differences between the sun and planets in oxygen and nitrogen, which are two of the most abundant elements in our solar system, said JPL in Pasadena, Los Angeles.Although the difference is slight, the implications could help determine how our solar system evolved, JPL said.NASA researchers drew the conclusion after analyzing samples returned by NASA's 2004 Genesis mission, according to JPL.The air on Earth contains three different kinds of oxygen atoms which are differentiated by the number of neutrons they contain. Nearly 100 percent of oxygen atoms in the solar system are composed of O-16, but there are also tiny amounts of more exotic oxygen isotopes called O-17 and O-18. Researchers studying the oxygen of Genesis samples found that the percentage of O-16 in the sun is slightly higher than on Earth or on other terrestrial planets. The other isotopes' percentages were slightly lower."We found that Earth, the moon, as well as Martian and other meteorites which are samples of asteroids, have a lower concentration of the O-16 than does the sun," said Kevin McKeegan, a Genesis co-investigator from University of California, Los Angeles (UCLA) and the lead author of one of two papers published this week in Science journal. "The implication is that we did not form out of the same solar nebula materials that created the sun -- just how and why remains to be discovered." Another paper detailed differences between the sun and planets in the element nitrogen. Like oxygen, nitrogen has one isotope, N- 14, that makes up nearly 100 percent of the atoms in the solar system, but there is also a tiny amount of N-15. Researchers studying the same samples saw that when compared to Earth's atmosphere, nitrogen in the sun and Jupiter has slightly more N-14, but 40 percent less N-15. Both the sun and Jupiter appear to have the same nitrogen composition. As is the case for oxygen, Earth and the rest of the inner solar system are very different in nitrogen."These findings show that all solar system objects including the terrestrial planets, meteorites and comets are anomalous compared to the initial composition of the nebula from which the solar system formed," said Bernard Marty, a Genesis co- investigator from Petrographic and Geochemical Research Center in Fracne and the lead author of the other new Science paper. " Understanding the cause of such a heterogeneity will impact our view on the formation of the solar system."Data were obtained from analysis of samples Genesis collected from the solar wind, or material ejected from the outer portion of the sun. This material can be thought of as a fossil of our nebula because the preponderance of scientific evidence suggests that the outer layer of our sun has not changed measurably for billions of years."The sun houses more than 99 percent of the material currently in our solar system, so it's a good idea to get to know it better, " said Genesis Principal Investigator Don Burnett of the California Institute of Technology, Pasadena, California. "While it was more challenging than expected, we have answered some important questions, and like all successful missions, generated plenty more."Genesis was launched in August 2000. The spacecraft traveled to Earth's L1 Lagrange Point about one million miles from Earth, where it remained for 886 days between 2001 and 2004, passively collecting solar-wind samples.JPL managed the Genesis mission for NASA's Science Mission Directorate, Washington. The Genesis mission was part of the Discovery Program managed at NASA's Marshall Space Flight Center in Huntsville, Alasca.
