BEIJING, Oct. 21 (Xinhuanet) -- A team of European researchers announced that they have found vast water vapor out of our solar system, according to a study in the U.S. journal Science Friday.Using Herschel Space Observatory, a European Space Agency satellite, the researchers observed that the vast water vapor enveloped a 175-light-year-away star and its surrounding dusk disk, which will eventually form a planet.The water vapor, which is "enough to fill thousand of Earth ocean", may rain down and seed the future oceans on the young planet, as it did on the Earth 4.5 billion years ago, the researchers suggested."Scientists have long suspected there were these reservoir of cold water hiding in the outer regions of planet disk, ... now the theory gets considerably stronger." said astronomer Michiel Hogerheijde of Leiden Observatory in the Netherlands.The finding not only explained where our Earth's ocean came from, but also indicated that there are likely to be many "ocean worlds" throughout the galaxies, he concluded.

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."

BEIJING, Oct. 11 (Xinhuanet) -- For women, chocolate consumption needs to be high, which can lower stroke risk, researchers from the Karolinska Institute, Sweden, reported in the Journal of the American College of Cardiology. The consumption of chocolate has been demonstrated to reduce diastolic and systolic blood pressure in randomized, short-term trials. Chocolate has also been shown to improve endothelial and platelet function, and to improve insulin resistance.Susanna Larsson Ph.D. and the team conducted the research on the Swedish Mammography Cohort's 33,372 adult females aged from 49 to 83 years without history of stroke, coronary heart disease, stroke, or diabetes.They found those who ate at least two chocolate bars each week appeared to have a 20 percent lower risk of stroke, compared to those of the same age and weight who rarely or never ate chocolate. But, they found, it was only those in the highest quartile of chocolate consumption who had a significant drop in stroke risk.The researchers explained that cocoa has flavonoids - powerful antioxidants that can suppress LDL, low-density lipoprotein, that can cause stroke and other cardiovascular diseases.

SAN FRANCISCO, Nov. 21 (Xinhua) -- E-commerce and online payment giant eBay announced on Monday that it has acquired New York-based technology startup Hunch, an online platform that delivers customized recommendations to users based on their individual tastes.Hunch's team and expertise in areas like machine learning, data mining and predictive modeling are expected to help eBay to integrate more advanced recommendations into its website, said the San Jose, California-based company."Unlike traditional online retail approaches, Hunch will enable eBay to move beyond standard item-to-item recommendations and use a broader variety of members' online tastes and interests to suggest new and interesting items for them to browse and buy on eBay," said the company in a press release.Terms of the deal were not disclosed. Technology news site TechCrunch founder Michael Arrington said in his personal blog prior to the acquisition announcement that eBay would acquire Hunch for 80 million U.S. dollars.Hunch, co-founded by popular photo-sharing service Flickr co- founder Caterina Fake with an 11-person team of MIT graduates, was open to the public in 2009. According to eBay, Hunch's employees will remain with the company in New York.

BEIJING, Jan. 10 (Xinhua) -- Chinese State Councilor Dai Bingguo on Tuesday attended a reception at the Great Hall of People in Beijing celebrating the 20th anniversary of the establishment of diplomatic ties between China and five Central Asian countries.China successively established diplomatic relations with Uzbekistan, Kazakhstan, Kyrgyzstan, Tajikistan and Turkmenistan in early January of 1992.In his address, Dai said relations between China and the five nations have achieved comprehensive and significant progress since they forged diplomatic ties 20 years ago, featuring frequent high-level visits, deepened political mutual trust, mutual support on major issues of each other's concern and expanded mutually beneficial cooperation in various fields.China and the five countries have maintained close coordination within the framework of the United Nations and the Shanghai Cooperation Organization and have positively contributed to safeguarding and promoting the world's peace, stability and development, he said.Noting China and the Central Asian nations are good neighbors, good friends and good partners, Dai said, no matter how the international situation changes, China will adhere to the policy of building friendship and partnership with its neighbors and support the five nations to independently choose their development path.China will unswervingly advance traditional friendship and cooperation with the five nations and will work with them to make unremitting efforts for building a harmonious world of lasting peace and common prosperity, he said.Dai said China will take the opportunity of celebrating the 20th anniversary to increase political mutual trust, expand mutually beneficial cooperation and develop traditional friendship with the five nations, in the hope of jointly creating a bright future for their relations.Li Xiaolin, president of the Chinese People's Association for Friendship with Foreign Countries, and diplomatic envoys from the five Central Asian nations also addressed the reception.
