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.

BEIJING, Nov. 7 (Xinhua) -- Chinese President Hu Jintao will meet with his U.S. counterpart, Barack Obama, at the 19th Asia-Pacific Economic Cooperation (APEC) Informal Leadership Meeting, said China's Assistant Foreign Minister, Wu Hailong, on Monday.He said the APEC summit will be held from Nov. 12 to 13 in Hawaii, with the theme of "seamless regional economy."According to Wu, speaking at a Foreign Ministry media briefing, Hu will attend the "APEC Leaders' Informal Meeting, Leaders' Dialogue with Representatives from APEC Business Advisory Council, and APEC CEO Summit."China hopes the APEC members will implement the economic growth strategy agreed last year, striving to achieve a balanced, inclusive, sustainable, innovative and safe economic growth, said Wu.China expects the APEC members to comprehensively promote regional trade and investment liberalization, he said, adding that all member states should fulfill their commitments and oppose all forms of trade protectionism.Wu said APEC should strengthen economic and technical cooperation to enhance the development ability of the developing members, and therefore to achieve common prosperity."APEC members generally hold positive attitudes toward U.S. proposals in various fields such as green growth, innovation policy. But some of the U.S.'s expected outcomes are beyond the capacity of the developing members, and they have expressed their difficulties and concerns," Wu said."However, all parties hope this meeting will achieve balanced and practical results".Assistant Commerce Minister Yu Jianhua said major topics to be discussed at the summit would include pushing forward the Doha Round negotiations, opposing trade protectionism, promoting green growth, and cooperation on developing regulations to govern emerging industries.He said China hopes the meeting will further promote the liberalization and facilitation of trade and investment in the Asia-Pacific region, push forward economic and technology cooperation, support multilateral trade systems, oppose trade protectionism, so as to inject vitality into world economic recovery and growth.On safeguarding the multilateral trade system, Yu said the decade-long Doha round talks have entered a critical period and the summit should be a strong voice for the early completion of the talks as well as joint resistance against trade protectionism.He said the APEC members should make joint efforts to remove discriminatory trade restrictions on high-tech products, and promote technology transfer and cooperation, so as to enable all members to benefit.On green growth, he said as APEC members differ sharply in their basis, conditions and levels in developing a green economy, the liberalization of environmental products and services should be pushed steadily.He also called on the developed economies to enhance capital and technical support for the developing economies, helping them in achieving their potential for sustainable development.

WASHINGTON, Oct. 9 (Xinhua) -- U.S. researchers have found a way to block, in an animal model, the damaging inflammation that contributes to many disease conditions. In their report receiving early online publication Sunday in Nature Biotechnology, researchers describe using small interfering RNA technology to silence the biochemical signals that attract a particular group of inflammatory cells to areas of tissue damage."The white blood cells known as monocytes play a critical role in the early stages of the immune response," says Matthias Nahrendorf, of the Massachusetts General Hospital (MGH) Center for Systems Biology, the paper's senior author. "We now know there are two subsets of monocytes -- an inflammatory subset that defends against pathogens and a reparative subset that supports healing. But if the inflammatory response is excessive, it can block the healing process and exacerbate conditions such as heart disease and cancer."Cells damaged by injury or disease release a cocktail of chemicals called cytokines that attract immune cells to the site of the damage. Inflammatory monocytes are guided to sites of tissue injury by a receptor protein called CCR2, and the MGH-led team devised a strategy targeting that molecule to block the inflammatory process but not the action of the reparative monocytes.Small interfering RNA (siRNA) technology prevents production of specific proteins by binding to associated messenger RNA molecules and preventing their translation. However, the technique requires extreme precision in developing the right siRNA molecule and delivering it to the correct cellular location.To make sure that their siRNA preparation targeted the right monocytes, researchers first confirmed that its use reduced levels of CCR2 in monocytes and increased levels of the fragments produced when siRNA binds to its target. They then showed that monocytes from mice treated with the siRNA preparation were unable to migrate towards CCR2's usual molecular target. Experiments in animal models of several important diseases showed that the siRNA preparation reduced the amount of cardiac muscle damaged by a heart attack, reduced the size and the number of inflammatory cells in atherosclerotic plaques and in lymphomas, and improved the survival of transplanted pancreatic islets."These inflammatory monocytes are involved in almost every major disease," Nahrendorf explains. "Anti-inflammatory drugs currently on the market hit every inflammatory cell in the body, which can produce unwanted side effects. This new siRNA treatment doesn't affect inflammatory cells that don't rely on the CCR2 receptor. That makes a big difference."

JERUSALEM, Dec. 11 (Xinhua) -- Kfir Damari, a communication systems engineer, has a dream: to land a miniature spacecraft on the moon sometime in 2013.Damari is one of the founders of Team SpaceIL, a non-profit organization representing Israel in the Google Lunar X Competition. The prize: 20 million U.S. dollars to the first of the 26 international teams currently registered that lands an unmanned craft on the moon, moves it a minimum of 500 meters across the lunar surface and transmits live high-resolution images back to earth."It's a tough mission, but I believe that if everyone in Israel joins hands it's possible," Damari told Xinhua.It is exactly the kind of entrepreneurial spirit that Israel, a country largely void of natural resources, counts on to make it a global leader in technological innovation.The two other men behind the initiative are Yonatan Winetraub, 25, a systems engineer at Israel Aerospace Industries (IAI) and a graduate of NASA's International Space University, and Yariv Bash, 31, a computer scientist and electronics engineer. The three first met at an innovation conference held by IAI a year ago.They describe the lander as a nano-satellite, whose design was revealed at the project's official inauguration ceremony on Thursday. The vessel weighs 100 kg, 80 percent of which are fuel, and is outfitted with rocket boosters and a panoramic camera."It's somewhat of a cellular phone sitting on a large fuel tank. All the technology that we require is basically contained in a typical smartphone with its communication and imaging features," Damari said.Launched in 2007, the Lunar X Prize aims to encourage space enthusiasts and engineers worldwide to develop cheap technologies for robotic space exploration.The Israelis have slated a modest 15 million U.S. dollars for the endeavor, 90 percent of which must come from private contributions according to the competition's rules. They have already raised 3.5 million dollars.The fact that they have formed a non-profit NGO in itself is worthy of praise. Most other teams have obtained the patronage of private corporations for whom money is not a problem, with some reportedly allotting up to 100 million U.S. dollars.To compensate for the disparities in funding, Damari and his partners have enlisted the support of 120 local volunteers, many of them engineers holding top positions in the technological and scientific community as well as the country's leading defense industries.Rona Ramon, the widow of Israeli astronaut Ilan Ramon killed aboard the Columbia Space Shuttle in 2003, was one of the sponsors too.In a bid to keep costs down, SpaceIL is heavily relying on the existing knowledge accumulated by Israel's defense industries over the past decades in building and launching mainly small, lightweight communications and military surveillance satellites into space.The challenge, Damari said, is to take that know-how a step further. The professionals who have volunteered for the project, among them some of Israel's most revered space experts, are currently grappling with several issues, including the ignition system, optic-visual navigation, beaming imagery to earth and the intricacies of enabling the nano-satellite a smooth lunar landing.SpaceIL is still searching for a third party that they will lease to launch their vehicle into space. Once there, they will have to navigate it to the moon on their own.While 20 million U.S. dollars is a major motivator for anyone, the Israelis said they're not seeking personal gain, but rather plan to invest the prize money in the vision that originally prompted their registration in December last year: inspiring the country's younger generation to pursue engineering and the sciences and to dream big, just like Neil Armstrong did when he disembarked from the Apollo 11 and took the first step on the moon in 1969.The funds, they said, will be funneled to educational programs that seek to rejuvenate youths' interest in science disciplines, which have been on the decline in the country's high schools in recent decades."We hope to attract the next generation of kids, to enable them to be engineers and scientists and to make sure that we have more people that can build spaceships in Israel in the future," said Damari.He and the other men behind the initiative also acknowledge that their motives are no less driven by patriotism. Winning the Lunar X has the potential to create national pride and put Israel "on the map as a start-up nation" by accomplishing a feat reserved for superpowers."The moon is something you see every day. I think that for me personally, space exploration is the way to enlist the nation to do something that has not yet been done," said Damari, who started programming aged six and wrote his first computer virus aged 11."It's also about exploring new borders, going the distance. (The project) will leverage Israel's space industry. I'm sure that all the industries that will partner with us will learn a lot and develop new applications, especially for the civilian market," he said.On Thursday, Israeli President Shimon Peres, whose name has become synonymous with the nation's hi-tech industries, honored the trio by unveiling their model at the ceremony held at MABAT -- IAI's missiles and space division near Tel Aviv."More than Israel is leading technology, it is likely to lead Israel. It's the key to our economy ... If they win the prize, and I'm sure they will, it will also reward Israel with the deepest appreciation and the best deterrence," Peres told a crowd of senior executives from local defense industries."I admire your audacity and vision," he complimented the three scientists.Will they realize their ambition? Damari expressed humble optimism, "It's not easy, but certainly possible ... We believe we can win."
