MOSCOW, Jan. 25 (Xinhua) -- China condemned the terrorist attack at Moscow's Domodedovo Airport that killed 35 on Monday, visiting Chinese State Councilor Dai Bingguo said on Tuesday."We have learned that a terrorist attack occurred at the Domodedovo Airport yesterday. We are simply shocked by this news. We condemn this terrorist attack," Dai said when meeting with Russian Foreign Minister Sergei Lavrov.During their meeting, Dai and Lavrov exchanged opinions on bilateral ties, regional situation and issues concerning the Shanghai Cooperation Organization and others.Dai met with Russian President Dmitry Medvedev and participated in the fifth round strategic security talks with Russian Security Council Secretary Nikolai Patrushev on Monday.

BEIJING, Jan. 27 (Xinhua) -- China's foreign exchange watchdog said Thursday that the surplus of Chinese banks' foreign exchange purchases to sales in client transactions increased 51 percent through 2010 to stand at 397.7 billion U.S. dollars at year-end.China' s institutional and individual clients sold 1.33 trillion U.S. dollars in foreign exchange to banks in 2010 while purchasing 932.7 billion U.S. dollars, said the State Administration of Foreign Exchange (SAFE) in an online statement.In 2009, the annual surplus fell 42 percent to 263.5 billion U.S. dollars, according to SAFE's data released in March 2010.The statement noted the figures did not include banks' own forex transactions and interbank transactions.The forex surplus in December 2010 totaled 51.5 billion U.S. dollars, as clients sold 146.2 billion U.S. dollars of foreign exchange, up 13 percent from November, while purchasing 94.7 billion U.S. dollars, up 12 percent, it said.Chinese banks received 1.89 trillion U.S. dollars for their clients in overseas business in 2010 and paid 1.59 trillion U.S. dollars to overseas business, it added.The SAFE only began releasing monthly and quarterly data on bank foreign exchange transactions in 2010.

WASHINGTON, May 11 (Xinhua) -- Johns Hopkins University researchers have demonstrated that human liver cells derived from adult cells coaxed into an embryonic state can engraft and begin regenerating liver tissue in mice with chronic liver damage.The work, published Wednesday in the journal Science Translational Medicine, suggests that liver cells derived from so- called "induced-pluripotent stem cells (iPSCs)" could one day be used as an alternative to liver transplant in patients with serious liver diseases, bypassing long waiting lists for organs and concerns about immune system rejection of donated tissue."Our findings provide a foundation for producing functional liver cells for patients who suffer liver diseases and are in need of transplantation," says Yoon-Young Jang, assistant professor of oncology at the Johns Hopkins Kimmel Cancer Center. "iPSC-derived liver cells not only can be generated in large amounts, but also can be tailored to each patient, preventing immune-rejection problems associated with liver transplants from unmatched donors or embryonic stem cells." A microsopic view shows human embryonic stem cells in various stages of differentiation into liver cells in this photo taken at Stanford University and released by the California Institute for Regenerative Medicine, March 9, 2009iPSCs are made from adult cells that have been genetically reprogrammed to revert to an embryonic stem cell-like state, with the ability to transform into different cell types. Human iPSCs can be generated from various tissues, including skin, blood and liver cells.Although the liver can regenerate in the body, end-stage liver failure caused by diseases like cirrhosis and cancers eventually destroy the liver's regenerative ability, Jang says. Currently, the only option for those patients is to receive a liver organ or liver cell transplant, a supply problem given the severe shortage of donor liver tissue for transplantation. In addition, mature liver cells and adult liver stem cells are difficult to isolate or grow in the laboratory, she says. By contrast, iPSCs can be made from a tiny amount of many kinds of tissue; and the embryonic stem- like iPSCs can grow in laboratory cultures indefinitely.For the study, Jang and colleagues generated human iPSCs from a variety of adult human cells, including liver cells, fibroblasts ( connective tissue cells), bone marrow stem cells and skin cells. They found that though the iPSCs overall were molecularly similar to each other and to embryonic stem cells, they retained a distinct molecular "signature" inherited from the cell of origin.

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.
