BEIJING, March 22 (Xinhuanet) -- NASA scientists are testing its next-generation Mars rover, which will land on Mars next year, under extreme conditions at space-simulation chamber in California, media reports said Tuesday.Scientists at NASA's Jet Propulsion Laboratory in Pasadena, Calif., say they've installed the Curiosity rover in a space-simulation chamber that can mimic the environment the probe will encounter on Mars.  After the chamber's large door was sealed last week, air was pumped out to near-vacuum pressure, liquid nitrogen in the walls dropped the temperature to minus 130 degrees Celsius, and a bank of powerful lamps simulated the intensity of sunshine on Mars.After the test period, the rover along with other portions of NASA's Mars Science Laboratory spacecraft including the cruise stage, descent stage and backshell -- part of protective covering -- will be shipped to the Kennedy Space Center for final preparation for the launch window from Nov. 25 to Dec. 18, 2011. Curiosity will study whether a selected area of Mars has offered environmental conditions favorable for microbial life and for preserving evidence about whether Martian life has existed.

VIENNA, April 12 (Xinhua) -- A protein group has been identified as an "allergy multiplier" that causes food allergy, a symptom that could also accompany other allergies and produce serious consequences, Austrian researchers said Tuesday.The so-called non-specific lipid transfer proteins (nsLTP) are believed to be the causes of food allergy, a research team from the Medical University of Vienna said in a new report.These plant allergens are found not only in many fruits and vegetables, but also in cereals and some types of pollen. Due to their compact structures, they are not degraded in the gastrointestinal tract and can trigger immune reactions that cause severe allergic symptoms, said the report.The researchers believe that with nsLTP identified as an " allergy multiplier," diagnostic and treatment procedures could be adapted and improved.

SAN FRANCISCO, March 29 (Xinhua) -- Amazon.com Inc. on Tuesday announced the launch of an on-line music storage service,which enables users to store digital music in the cloud and access it from computers and devices running Google's Android operating system.The new service, called "Cloud Drive," offered customers five gigabytes of free storage on Amazon Web servers for all kinds of digital files, including music, photos, videos and documents. For paid plans, users can purchase storage space starting at 20 U.S. dollars a year for 20 gigabytes.The on-line retailer also launched "Cloud Player for Web" and " Cloud Player for Android." The former allows users to get the media files they stored on Amazon's servers from a Web browser on a Mac or PC. The latter lets users play music they have uploaded on Cloud Drive, computers or a smartphone that runs Android operating system.Analysts said Amazon is stepping up its rivalries with Apple and Google. Both companies are also working on similar services, allowing users to store their music on-line and access it from any compatible device.Media reports said that Apple was pushing hard to launch a digital music locker service in April. Google was also reported to be testing its own digital locker service but it still needs to make agreements with major music labels.

BEIJING, Feb.11 (Xinhua) -- Representatives from different sectors have given feedback on drafts of the government work report and China's economic and social development blueprint for the next five years, the State Council, China's cabinet, said Friday.Premier Wen Jiabao chaired five seminars from Jan. 20 to 27, at which representatives of various sectors of society were invited to voice their views on the documents, according to a State Council statement.The 12th five-year program, or the national development plan for 2011 to 2015, and the government work report will be delivered for review at the plenary session of the National People's Congress (NPC), China's top legislature, in March.Experts from social economic organizations along with those from science and technology, education, health, culture and sports circles attended the meetings, as well as members of non-communist parties.Participants at the seminars agreed on the framework and main content of the documents. They also gave some suggestions and proposed a couple of revisions to the report and the development plan.Most suggestions focused on China's economic restructuring, income distribution adjustment, modern agricultural development, scientific innovation, reform of the yuan exchange rate formation mechanism, property market regulation and affordable housing construction, and further improvement in education and medical care system.The forums also invited 11 grass-roots representatives, including farmers, technicians, and owners of small businesses, who raised suggestions to boost farmland irrigation construction, train more technicians, and help with the development of small and medium enterprises.Wen said the feedback will be "of great help" when revising both the government work report and 12th five-year plan, as well as to the work of the government.

BEIJING, May 24 (Xinhuanet) -- Facebook founder Mark Zuckerberg welcomed more kids to join in the social network site, according to International Business Times reports on Monday.He made this comment in the NewSchools Summit in California.Zuckerberg said Facebood can help young kids to learn from each other and acquire more knowledge about using the internet."That will be a fight we take on at some point," Zuckerberg said, "My philosophy is that for education you need to start at a really, really young age." At the moment, Facebook officially does not allow the children younger than 13 to sign up, since the Children's Online Privacy Protection Act (COPPA) forbids children under 13 from joining an online service which collects user information data.However it recently revealed that 7.5 million Facebook users were younger than that, accoding to a study released last week by Consumer Reports.Some experts suggested Facebook may not be in any position to provide that education in its current form. "The lessons of digital citizenship have to start young, but I don't feel that Facebook is the venue to have those lessons occur. A lot of missteps happen on that site without a lot of coaching." said Dr. Gwenn O'Keeffe, an expert on young children's education.
