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.

WELLINGTON, May 24 (Xinhua) -- New Zealand researchers have found a way to stop the growth of certain cancer tumors by " silencing" a group of PAX genes, members of a small family of genes that play important roles in embryonic development, but also allow cancer cells to grow and divide in adult tissue.In an article published in UK medical journal Oncogene, Otago University Professor Michael Eccles and colleagues revealed how they used the PAX8 gene to kill cancer cells.After detecting high levels of PAX8 protein in the majority of kidney, ovarian and thyroid cancers they studied, the researchers used molecular techniques to silence the PAX8 gene in several cancer cell lines."We found that these PAX8-depleted cancer cells ceased growing and dividing. The cells were essentially stopped in their tracks through the failure of multiple mechanisms and pathways crucial to their cell division cycle. They then entered into a state called senescence in which they no longer divided, and after that they ultimately died," Eccles said in a statement from the university Tuesday.The findings suggested that PAX8 could be a good target for the development of new cancer therapies, he said."Any resulting drugs would be a long way down the road, but in the meantime this research helps confirm that a focus on PAX genes may prove to be a fruitful line of attack against a number of cancers," he said.The research was supported by grants from the Health Research Council of New Zealand. It formed the main piece of work carried out by Otago doctoral graduate Caiyun (Grace) Li, now a postdoctoral fellow at Stanford University. Study co-authors also included Professor Antony Braithwaite and master's student Jen Nyman.In 2003, research led by Eccles discovered that proteins from one or more of the nine PAX genes were present in many common cancers. They found that "silencing" the gene expression of PAX2 in ovarian and bladder cancer cells, and of PAX3 in melanoma, led to the rapid death of the cells.

WASHINGTON, Jan. 19 (Xinhua) -- China and the United States have agreed to further boost their bilateral relationship toward a cooperative partnership for the benefit of the whole world, President Hu Jintao said Wednesday.The visiting Chinese leader presented the course forward at a joint press conference at the White House with his U.S. counterpart Barack Obama following their eighth meeting in two years.During the talks, conducted in "a candid, pragmatic and constructive atmosphere," the two sides reached "important agreement on China-U.S. relations and major international and regional issues of shared interests," according to the Chinese president.Chinese President Hu Jintao (2nd L) holds a bilateral meeting with U.S. President Barack Obama (2nd R) at the White House in Washington, the United States, Jan. 19, 2011. "We both agree to further push forward the positive, cooperative and comprehensive China-U.S. relationship," Hu said, adding that both sides also pledged to forge "a China-U.S. cooperative partnership based on mutual respect and mutual benefit" for the benefit of the two countries and beyond.Meanwhile, the two sides "should firmly adhere to the right direction," respecting each other's core interests and handling their relations with a long-term perspective, which will enable both countries to make greater contributions to world peace and development, he said.Citing the growing number of global challenges, the Chinese president stressed that Beijing and Washington "share expanding common interests and shoulder increasing common responsibilities."Accordingly, he added, the two sides have agreed to strengthen exchanges and cooperation in economy, trade, environment, education, science and technology, non-proliferation and counter-terrorism among many other fields.During Hu's ongoing state visit, the two countries signed a number of cooperation agreements. "These will inject fresh momentum into our bilateral cooperation and create a great many job opportunities for our two countries," Hu said.He added that he and Obama also discussed some disagreements in the economic and trade area, with both sides pledging "to continue to appropriately resolve these according to the principle of mutual respect and consultation on an equal footing."Commenting on the relations between the countries's armed forces, Hu said, "We believe expansion of military exchanges and cooperation will be conducive to deepening mutual trust between our two countries."On the situation on the Korean Peninsula, he said that both countries agreed to work together with relevant parties to maintain peace and stability on the peninsula, promote denuclearization of the peninsula and achieve lasting peace and security in Northeast Asia.The Chinese leader reaffirmed China's firm commitment to the path of peaceful development and a win-win strategy of opening up, and appreciated Obama's commitment to a positive and constructive China policy."China is a friend and partner of all countries, and China's development is an opportunity for the world," he said.

BEIJING, April 19 (Xinhuanet) -- The case in the Hollywood blockbuster "The Social Network" continues in real life.Twins Cameron and Tyler Winklevoss on Monday filed another appeal against their Harvard classmate and Facebook founder Mark Zuckerberg.The Winklevosses claim that the case needs to be reviewed by a special 11-judge panel in the latest appeal, after a three-judge panel of the 9th U.S. Circuit Court of Appeals ruled against the brothers last week.The twins initially claimed that Zuckerberg had stolen their idea for the website but agreed to drop their lawsuit in 2008 in exchange for 20 million dollars in cash and stock in the company.But later they discovered the stock was worth less than claimed at the time and sought to have the deal voided, the brothers said.
