BEIJING, Sept. 1 (Xinhua) -- Chinese scientists have decided to reschedule the launch of the Tiangong-1, an unmanned space module, due to the failed launch of an experimental orbiter, a spokesperson with the project said Thursday.The decision to delay the launch was based on the consideration that the carrier rocket Long-March II-F, which would be used for the upcoming launch, belongs to the same series as the malfunctioning one that led to the experimental orbiter SJ-11-04 failing to enter Earth's orbit in August."As the investigation into the malfunction of the rocket Long-March II-C remains underway, it is not clear yet whether the malfunction is linked with the Long-March II-F," the unnamed spokesperson said.Previously, the Long-March II-F was expected to send the 8.5-metric ton Tiangong-1, or "Heavenly Palace 1," into space in the second half of this year to perform the nation's first space-docking procedure.The Tiangong-1 will dock with the unmanned Shenzhou-8 spacecraft, which will be sent into space after the Tiangong-1's launch."The specific launch date for the Tiangong-1 will be set based on the results of the investigation into the malfunctioning rocket," the spokesperson said, adding that the project's teams are currently double-checking every product that will be involved in the space-docking.The Shenzhou-8 spacecraft, the Long March II-F carrier rocket, and the Tiangong-1 have all been transferred to the Jiuquan Satellite Launch Center in northwest China's Gansu Province, the spokesperson said.

MOSCOW, Aug. 24 (Xinhua) -- A Russian Progress cargo ship crashed into Siberia after failing to reach the right orbit Wednesday. The crash marked the second failure in space launch in less than a week and the third in this year, prompting local media to suspect a major reshuffle in Russia's space industry.UNPRECEDENTED FAILUREThe Progress M-12M unmanned freighter was launched to the International Space Station from Baikonur space center in Kazakhstan on Wednesday. It was expected to reach a near-Earth orbit in about nine minutes after launch.However, after the 325th second of the flight, which was just a few seconds before the vessel should reach the orbit, the ground control center lost it.Russian space agency Roscosmos confirmed later that the cargo ship failed to reach the orbit and fell down. Russian Progress M-12M cargo ship is launched to the International Space Station from Baikonur space center in Kazakhstan on Wednesday, Aug. 24, 2011. It has failed to reach the orbit, the Interfax news agency reported.The malfunction of the Soyuz-U rocket's engine was generally believed to be the cause of the accident, according to local media.A source in the space industry said the spaceship had sent a breakdown report while separating from the Soyuz rocket.Some unconfirmed reports said the fuel tank of the booster leaked and the engine was automatically turned off to avoid explosion.The wreckage of the Progress cargo ship has already fallen in southern Siberia's Altai Republic, where a big explosion was heard by locals, reported RIA Novosti news agency.A state investigation committee has been formed to look into the first ever loss of a Progress freighter.CONCERNS OVER FUTUREThe unprecedented accident raised concerns over the reserves of the six crew members on board the ISS.The ship was loaded with over 3.5 tons of supplies for the ISS, including scientific materials, oxygen, water and food.According to Russia's Ground Control, the loss of these supplies will not affect the ISS crew as there are enough stocks of necessities for two to three months.Also, there is no need for premature return of the crew, said Vladimir Solovyov, a space official.However, it still casts some shadow over the ISS program that relies on Russia exclusively following the retirement of U.S. shuttles.A source from the Russian space industry said the scheduled launches of the Soyuz rockets are likely to be suspended until the reasons of the accident are established.This means that current crew members of the ISS would likely stay longer in the space than planned, as the new members might not be able to replace them on schedule, the source explained. Solovyov said the launch of the next Progress is scheduled for October 28.So far, Roscosmos has refrained from comments regarding the possible halt in manned missions aboard Soyuz carrier rockets."Comments will follow. Now it is necessary to determine the causes of today's abortive launch of a Soyuz-u carrier rocket with the Progress M-2M transport ship," Roscosmos told Itar-Tass news agency.Local media raised the prospect of a major reshuffle in Russia' s space industry as the country has lost a total of six space vehicles over the past nine months.On Aug. 18, a carrier rocket Proton-M failed to deliver to the orbit communication satellite Express-AM4. Earlier in February, Russia had lost a satellite named Geo-IK2.In December 2010, a booster malfunction resulted in the loss of three satellites in the global positioning and navigation system GLONASS.

New York, Sept. 23 (Xinhua) -- A Chinese scientist was presented a prestigious U.S. award on Friday for the discovery of artemisinin, a drug therapy for malaria that has saved millions of lives across the globe, especially in the developing world. Pharmacologist Tu Youyou, 81, became the first scientist on the Chinese mainland to win Lasker Award, known as "America's Nobels" for their knack of gaining future recognition by the Nobel committee.Tu, a scientist at the China Academy of Chinese Medical Sciences in Beijing, pioneered a new approach to malaria treatment that has benefited hundreds of millions of people and promises to benefit many times more. By applying modern techniques and rigor to a heritage provided by 5000 years of Chinese traditional practitioners, she has delivered its riches into the 21st century."Not often in the history of clinical medicine can we celebrate a discovery that has eased the pain and distress of hundreds of millions of people and saved the lives of countless numbers of people, particularly children, in over 100 countries," Lucy Shapiro, a member of the award jury and professor of Stanford University, said while describing Tu' s discovery.Shapiro said the discovery, chemical identification, and validation of artemisinin, a highly effective anti-malarial drug, is largely due to the "scientific insight, vision and dogged determination" of Professor Tu and her team. She thought Professor Tu's work has provided the world with arguably the most important pharmaceutical intervention in the last half century."The discovery of artemisinin is a gift to mankind from traditional Chinese medicine," Tu said while receiving the award. "Continuous exploration and development of traditional medicine will, without doubt, bring more medicines to the world."

UNITED NATIONS, June 9 (Xinhua) -- The message delivered by scores of speakers on the second day of the three-day UN High Level Meeting on AIDS on Thursday, marking 30 years of the pandemic, was that most of their countries were making progress but increased efforts had to be made with greater cooperation needed among nations.In the case of developing states, gratitude was expressed for past help but more aid was needed to continue the battle.Despite the similarities in content, the chair, UN General Assembly President Joseph Deiss, repeatedly appealed to speakers to limit their speeches to their allotted five minutes, warning at the halfway point that if everyone was taking an extra few minutes, a fourth day would have to be added to the agenda.One of the briefest addresses, well under time, was delivered by Yin Li, China's vice health minister, which he referred to as " a responsible developing country."Briefly listing some of the steps taken, the Chinese vice minister focused on achieving the UNAIDS goal of the three Zs -- " Zero new HIV infections, zero discrimination and zero AIDS-related deaths.""We should unite to generate a joint force, irrespective of gender, skin color, nationality, beliefs, values and ideology. Developed countries should further provide developing countries with unselfish, unconditional financial and technical support," he said. "Developing countries should place AIDS control in a position as important as economic development and actively explore prevention and treatment mode consistent with national conditions. ""Second, given the increasing disease burden of AIDS," he said, "the private sector and relevant organizations should shoulder more social responsibility."On the one hand efforts should be made to mobilize more resources in AIDS to better implement prevention, treatment and care measures; on the other hand, multinational drug manufacturers should reduce by a large margin the price of drugs, testing equipment and reagents through technology transfer, contract manufacturing and reduction of monopoly profits in order to promote universal access to treatment services," Yin added.Since AIDS prevention and treatment in China is an important component in the global fight against AIDS, he said, "Progress made in China is a positive contribution globally."The High Level Meeting on AIDS is taking place 10 years after the UN Special Session on HIV/AIDS and five years since signing of the Political Declaration in which UN Member States committed to universal access to HIV prevention, treatment, care and support.Norway's minister of the environment and international development, Erik Solheim, said, "Prevention and treatment must be mutually reinforcing and better treatment regiments need to be made available."He called for development of innovative methods for prevention.While Solheim said "remarkable" results had been achieved in the last three decades, there still was a need for a " transformation of current working methods."AIDS must be taken out of isolation into an "integrated approach," noting that HIV response has to be connected with UN Secretary-General Ban Ki-moon's Global Strategy for Women's and Children's Health and "HIV and AIDS programs should be mainstreamed into national health systems, he said.Solheim said that the social, political and economic empowerment of women is crucial and he welcomed the establishment of the new UN agency UN Women."The burden of HIV in the world is reduced but major challenges remain," the minister said. "Our experience is that the approaches that work well on HIV, are those based on rights and on promoting the dignity of people."Celsius Waterberg, the health minister of Suriname, said the nation "is among the few countries in the Caribbean where the incidence of HIV infection has decreased by more than 25 percent."The strides forward are due to a national multi-sectoral HIV Council, setting up structures to provide leadership in quality of services and training in revised treatment protocols, he said.Suriname, the smallest sovereign state in South America, on the northeast coast of the continent, also introduced combined prevention tools and implemented pilot projects successful in mobilizing men for circumcision as an additional preventive measure, Waterberg said.Challenges that need to be overcome include harmful traditions and customs, misconceptions and adverse beliefs, language barriers in a multilingual society and vulnerability of small communities and individuals due to HIV-related stigma, gender inequalities and poverty, he said.Victor Makwenge Kaput, health minister of the Democratic Republic of Congo, said that although the government had made progress in supporting individuals living with HIV and protecting the uninfected, it continues to face many challenges. Indeed, HIV prevalence stood at 3.7 percent for pregnant women and 3 percent for the general population, he said.AIDS' victims increasingly are women and youth with infections particularly concentrated along the Congo River, the minister said. Today, 1.2 million citizens are infected. Total population in the third largest country in Africa, about the size of Western Europe, is 71 million.He said women account for roughly 71,000 new infections each year and the government is now paying particular attention to mother-to-child transmission.Kaput said his long war-torn nation is committed to the global vision of zero infections and appealed for support to curb the spread of HIV.

SAN FRANCISCO, June 15 (Xinhua) -- As social networking sites like Facebook and Twitter grow worldwide, more Internet retailers are beefing up their efforts to add social twists to their business, trying to define the idea of "social commerce" and capitalize the opportunity.On Wednesday, online auction giant eBay revealed some of the social features it is planning to launch later this year, while Copious, a San Francisco-based startup, launched its online social commerce marketplace with a slogan of "buying from and selling to people, not strangers."Copious asks users to log in through their Facebook accounts and allows buyers and sellers to see if they have friends in common in their social networking sites. Buyers can see more information about a seller and also see whether anyone in their networks has purchased, shared or commented on an item from a specific seller, rather than anonymity or simple profiles on sites like eBay and Craigslist.As for sellers, Copious has a social pricing mechanism that enables a seller to offer buyers discounts for sharing listings on Facebook and for following the seller on Copious.Jonathan Ehrlich, Copious co-founder and former Facebook head of marketing, told technology blog TechCrunch that the site is centralized around using social data as a signal to help users understand and trust other parties.According to Copious, the startup founded in January 2011 has raised two million U.S. dollars in funding from Foundation Capital, Google Ventures, Blackberry Partners Fund and a number of Silicon Valley angel investors.Also on Wednesday, Christopher Payne, vice president and head of eBay North America, delivered a keynote speech at the Internet Retailer Conference and Exhibition 2011 in San Diego, revealing some features eBay is launching during the social trend.One feature will enable users to log in their Facebook account on eBay's homepage to get product recommendations based on one's purchasing history and things they have "liked" on their Facebook page. Another feature will allow users to post multiple products on their Facebook page to get their friends' opinions and ask them to vote for the final purchase.EBay has been stepping up its social efforts, and Payne said on Wednesday that social is a top-level initiative for Internet retailers. Last month, eBay hired former Yahoo executive Don Bradford to lead its social commerce efforts. Last November, it launched Group Gifts service, enabling users to chip in to buy a gift for someone.A research by Adgregate Market in March showed that more brand websites are losing traffic to their Facebook pages. The study revealed that the "Facebook stores" of most Internet retailers are more efficient at acquiring visitors, indicating social commerce is poised to take off.Although the idea of social commerce is still new, more companies are trying to seize the opportunity in their own moves.There are many other companies taking the social commerce model. Oodle, the exclusive provider of classified ads on the Facebook Marketplace, rolled out a series of social features last December to make more money from social classifieds.In February, Payvment Inc. launched a Facebook Mall, where consumers can shop for more than 1.2 million products among 60,000 retailers in a single shopping cart.Yardsellr, which is often called "an eBay for Facebook," allows sellers to list items at fixed prices in different categories called "blocks," such as jewelry and purses. Prospective buyers can "like" the "blocks" they are interested in on the Yardsellr website or its Facebook page, and then they will get Facebook news feed if a seller has something to offer in the category.Yardsellr said 1.5 million people were following its "blocks" by late December 2010 and the number of new followers is growing by 20,000 daily.
