WASHINGTON, Nov. 8 (Xinhua) -- NASA plans to add an unmanned flight test of the Orion spacecraft in early 2014 to its contract with Lockheed Martin Space Systems for the multipurpose crew vehicle's design, development, test and evaluation, the U.S. space agency announced Tuesday.This test supports the new Space Launch System (SLS) that will take astronauts farther into space than ever before, and provide the cornerstone for America's future human spaceflight efforts."President Obama and Congress have laid out an ambitious space exploration plan, and NASA is moving out quickly to implement it," NASA Associate Administrator for Communications David Weaver said in a statement. "This flight test will provide invaluable data to support the deep space exploration missions this nation is embarking upon."Orion is part of the now defunct Constellation program canceled under President Barack Obama's 2011 budget proposal. Instead Obama urged NASA to work toward sending humans to an asteroid and then on to Mars -- and NASA says it wants to go ahead with that as quickly as possible.This Exploration Flight Test, or EFT-1, will fly two orbits to a high-apogee, with a high-energy re-entry through Earth's atmosphere. Orion will make a water landing and be recovered using operations planned for future human exploration missions. The test mission will be launched from Cape Canaveral to acquire critical re-entry flight performance data and demonstrate early integration capabilities that benefit the Orion, SLS."The entry part of the test will produce data needed to develop a spacecraft capable of surviving speeds greater than 20,000 mph and safely return astronauts from beyond Earth orbit," Associate Administrator for Human Exploration and Operations William Gerstenmaier said. "This test is very important to the detailed design process in terms of the data we expect to receive."

HONOLULU, the United States, Nov. 12 (Xinhua) -- Chinese Commerce Minister Chen Deming has said that China-ASEAN Free Trade Area, launched at the beginning of last year, accords with the mutual interests of China and ten nations of the Association of Southeast Asian Nations (ASEAN) and brings advantage to both sides.Chen made the remarks during his meetings with Indonesian Trade Minister Gita Wirijawan and Thai Deputy Prime Minister and Commerce Minister Kittirat Na Ranong on Friday on the sidelines of the week-long Asia-Pacific Economic Cooperation (APEC) meetings held in Honolulu, Hawaii.According to information made available to Xinhua Saturday, Chen said in his meeting with Gita that China and Indonesia have witnessed a sound development of bilateral economic and trade relations. The China-ASEAN Free Trade Area has provided a new platform for the bilateral economic and trade cooperation, with more benefits and opportunities for enterprises from both countries.Chinese enterprises, especially those from the southern part of China, are keen to invest in Indonesia, said Chen, adding that China would like to discuss with Indonesia on creating areas similar to industrial parks so as to attract more Chinese enterprises and enterprises from other countries to invest in the Southeast Asian country.Gita said Indonesia will commit to the consensus reached between leaders of both countries to increase the volume of bilateral trade from current 34 billion U.S. dollars to 80 billion U.S. dollars in three or four years.He welcomed Chinese enterprises to invest in Indonesia, adding it will be conducive to the realization of the trade goal.Saying that the economies of Indonesia and China have been complimentary to each other, Gita expressed the will of comprehensive and long-term cooperation between both sides.During his meeting with Kittirat, Chen first expressed sympathy to the flood victims in the country, saying that China would like to offer assistance to the rescue and reconstruction efforts and strengthen cooperation in areas including infrastructure construction with Thailand.He said China and ASEAN nations should promote the substantial cooperation among member nations of the China-ASEAN free trade area, the largest free trade area in the world, improve infrastructure including highways, railroads, ports, telecommunication and electricity, so as to benefit the enterprises and people in the regions.China encourages enterprises to invest in the ASEAN nations and would like to conduct cooperation with enterprises from Thailand and other countries, Chen added.Kittirat, expressing his gratitude to China's help to the flood disaster, said that Thailand attaches great importance to the China-ASEAN Free Trade Area.Noting that Chinese enterprises are well-experienced in the construction of highways, railroads and bridges, he said Thailand welcomes Chinese enterprises to participate the construction and investment projects in these areas.

WASHINGTON, Oct. 13 (Xinhua) -- U.S. researchers have corrected sickle cell disease in adult laboratory mice that had been bred to have the inherited blood disorder by activating production of a special blood component, according to a study published online Thursday in the journal Science.Sickle cell disease results from an abnormality in hemoglobin, the protein found in red blood cells that is responsible for transporting oxygen throughout the body. People living with sickle cell disease have two copies of an altered gene that produces sickle hemoglobin instead of normal adult hemoglobin. Sickle hemoglobin changes shape after releasing its oxygen, causing the red blood cell to become stiff, misshapen and sticky, and slowing blood flow to tissues. This process damages organs and causes pain.The study tested a new approach to increasing the production of a third form of hemoglobin -- fetal hemoglobin. Production of fetal hemoglobin predominates before birth, but turns off thereafter as adult hemoglobin production takes over. People with sickle cell disease are unable to make normal adult hemoglobin, and instead make sickle hemoglobin starting in infancy.An elevated level of fetal hemoglobin within the red blood cell reduces the tendency of sickle hemoglobin to change the shape of red blood cells. Considerable research has shown that the drug hydroxyurea increases production of fetal hemoglobin and reduces the number of pain crises and other complications of sickle cell disease in adults and children. However, not all patients respond well to hydroxyurea, and adverse side effects are a concern.The current study explores a more targeted approach to increasing fetal hemoglobin production. It builds upon earlier studies that discovered a protein called BCL11A normally suppresses the production of fetal hemoglobin soon after birth. The researchers viewed the BCL11A protein as a target for therapy and decided to see what would happen if they blocked production of the protein.The paper details how the research team silenced the mouse gene that produces the BCL11A protein in mice with sickle cell disease. Silencing the gene turned off production of the BCL11A protein and allowed the adult mice to continue to produce fetal hemoglobin. It appears to have eliminated disease symptoms without affecting other aspects of blood production."This discovery provides an important new target for future therapies in people with sickle cell disease," said Susan Shurin, acting director of the U.S. National Heart, Lung, and Blood Institute, which co-funded the study. "More work is needed before it will be possible to test such therapies in people, but this study demonstrates that the approach works in principle."Approximately 100,000 Americans live with sickle cell disease. It is most prevalent in people of African, Hispanic, Mediterranean, and Middle Eastern descent. There is no widely available cure for sickle cell disease. Bone marrow transplants have cured some patients, but the treatment is not without risk and most patients do not have relatives who can donate compatible and healthy bone marrow to them.

SAN FRANCISCO, Nov. 3 (Xinhua)-- Amazon on Thursday launched an e-book lending service for owners of its Kindle devices, letting them borrow one digital book per month with no due date.Amazon said Kindle owners with an annual Prime membership can choose from thousands of books to borrow for free, including over 100 current and former New York Times Bestsellers. The online retail giant did not give an exact figure on the number of books of the new service.According to the company, readers' notes, highlights and bookmarks in borrowed books will be saved, so they will have them later if they purchase or re-borrow the book. Customers can have one book out at a time and the borrowed book should be returned through the Kindle device when they want to borrow a new one.In a press release, Amazon said it has reached agreement with publishers for a vast majority of titles for a fixed fee. But in some cases, Amazon is purchasing a title each time it is borrowed by a reader under standard wholesale terms.An Amazon Prime membership costs 79.99 U.S. dollars a year in the United States and gives members free two-day shipping and free access to the company's video streaming service containing some 13, 000 TV shows and movies.The new service is not compatible with smartphones, personal computers or tablet computers from other vendors running with Kindle apps, which makes Amazon's Kindle e-ink readers and its latest low-price tablet Kindle Fire more enticing to customers.According to Amazon, the Kindle Fire, which is priced at 199 U. S. dollars, will be released on Nov. 15.
