MOSCOW, Jan. 24 (Xinhua) -- Russian President Dmitry Medvedev and visiting Chinese State Councilor Dai Bingguo held talks here on Monday, discussing prospects for the development of cooperation between the two countries.Medvedev and Dai Bingguo discussed the development of Russian- Chinese bilateral cooperation and interaction on the international arena.The Russian president said the Sino-Russian strategic partnership of coordination is developing further in all aspects, as the leaders of the two nations kept close contact during last year and cooperation in the economic and trade sphere has been deepened.Russia sees China as its closest partner, a position that will never be changed, Medvedev stressed.Russia is willing to work together with China to promote all- around cooperation and coordination on international and regional issues, Medvedev said.He said the strategic security talks between Russia and China, a major goal of Dai's current visit, have served as an important channel for bilateral coordination and exchanges, and played a pivotal role in enhancing bilateral strategic mutual trust.Dai Bingguo, who arrived in Moscow Sunday for a three-day visit, said that the first ten years of the 21st century had been important for Sino-Russian relations.China attaches great importance to the strategic coordination with Russia and is willing to work with Russia to develop their strategic partnership of coordination at a higher stage, the Chinese state councilor said.

SAN FRANCISCO, April 4 (Xinhua) -- Google Inc. on Monday announced that it is bidding for patent portfolio of Nortel Networks in the bankruptcy auction for the Canadian telecommunications equipment maker.In a press release, the Toronto-based Nortel said Google has agreed to buy all of its remaining patents and patent applications for 900 million U.S. dollars in cash.Nortel, which filed for bankruptcy protection in 2009, expects the auction to be held in June this year, pending Canadian and U.S. court approvals.Nortel has selected Google's bid as the "stalking-horse bid," or the starting point against which others will bid prior to the auction.The agreement with Google includes the planned sale of about 6, 000 Nortel patents and patent applications spanning wireless, wireless 4G, data networking, optical, voice, Internet, service provider and semiconductors.According to Nortel, the patent portfolio touches nearly every aspect of telecommunications and additional markets, including Internet search and social networking."This is an unprecedented opportunity to acquire one of the most extensive and compelling patent portfolios to ever come on the market," George Riedel, Nortel's chief strategy officer, said in a statement.Google argued that the bid would help protect it from patent litigation and foster innovation.The technology industry has recently seen an explosion in patent litigation, often involving low-quality software patents, which threatens to stifle innovation, Kent Walker, Google's general counsel, said in a blog post, believing the best defense against such litigation is to have a "formidable patent portfolio. ""So after a lot of thought, we've decided to bid for Nortel's patent portfolio in the company's bankruptcy auction," he said."If successful, we hope this portfolio will not only create a disincentive for others to sue Google, but also help us, our partners and the open source community -- which is integrally involved in projects like Android and Chrome -- continue to innovate," Walker noted.

LOS ANGELES, May 15 (Xinhua) -- Using a simple, minimally- invasive technique to analyze cells from the interior of the nose, U.S. researchers have detected lung cancer in its earliest stage.For the study, the researchers at the Boston University Medical Center collected nasal epithelial cells from thirty three smokers who were undergoing medically-indicated bronchoscopies for suspicion of lung cancer, according to the American Association for the Advancement of Science (AAAS) on Sunday.Of these patients, 11 were found to have benign disease and 22 had lung cancer. Brushings were taken from the right or left nostril and profiled on microarrays, a process that allows researchers to study gene expression changes.The researchers identified 170 genes that were differentially expressed between patients with and without lung cancer. They also found that genes linked to colon cancer and adenocarcinoma, as well as genes that trigger cell division and blood vessel growth, were expressed more heavily in patients with cancer. Genes involved in tumor suppression were also expressed at lower levels in these patients.Earlier studies have used gene expression differences in the bronchial airways to identify lung cancer in its early stages. The researchers relied on those results to design the current study."In this study we used the same principle as we used in our earlier studies of bronchial tissue, only this time, those methods were used to study nasal cells," said study author Christina Anderlind, MD, Instructor of Medicine. "Our hypothesis was that the upper airway epithelium of smokers with lung cancer displays a cancer-specific gene expression pattern, and that this airway nasal gene expression signature reflects the changes that occur in lung tissue."

LOS ANGELES, May 25 (Xinhua) -- NASA project managers bade farewell to the Mars rover Spirit on Wednesday after sending a final set of commands to the stranded vehicle.This marks the completion of one of the most successful missions of interplanetary exploration ever launched, NASA's Jet Propulsion Laboratory (JPL) said."Last night, just after midnight, the last recovery command was sent to Spirit," said John Callas, the Mars Exploration Rover Project manager at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, Los Angeles."It would be an understatement to say this was a significant moment. Since the last communication from Spirit on March 22, 2010, as she entered her fourth Martian winter, nothing has been heard from her."NASA has tried in vain to regain communication with Spirit since it got stuck in sand about two years ago. The rover last communicated on March 22, 2010, as Martian winter approached and the rover's solar-energy supply declined.NASA checked frequently in recent months for possible reawakening of Spirit as solar energy available to the rover increased during Martian spring, but to no avail.A series of additional re-contact attempts ended on Wednesday, designed for various possible combinations of recoverable conditions, according to JPL."Our job was to wear these rovers out exploring, to leave no unutilized capability on the surface of Mars, and for Spirit, we have done that," said Callas.

BEIJING, Feb. 15 (Xinhua) -- China's health authorities Tuesday vowed to improve their response to food safety incidents.The ministry would issue a protocol "as early as possible" on how to respond to and investigate food safety incidents, said Vice Health Minister Chen Xiaohong at a national meeting on food safety in Beijing.It would also provide better training for officials and professionals working in the field, Chen said.Last year, the ministry initiated investigations into several incidents such as milk powder that allegedly caused infant girls to grow breasts and illegal soup additives by restaurants.In the milk powder case, the investigation found no evidence that Synutra International's products had caused the problem. Media reports said the company was the victim of dirty tricks by a rival firm.In addition, the ministry blacklisted 48 substances illegally added to food and 22 misused food additives last year.The ministry would include projects related to food safety in state-sponsored health programs giving free medical services to the public in next five years, Health Minister Chen Zhu said at the same meeting.But Chen did not give details about what kind of projects they will be.Under the current six state health programs, the government provides free cataract surgery for the needy, free breast and cervical examinations for rural women, free hepatitis B vaccines, free folic acid pills for rural women, new cooking stoves in rural homes to prevent fluorine poisoning caused by coal stoves as well as modern toilets for rural residents.
