WASHINGTON, May 27 (Xinhua) -- Two U.S. astronauts conducted the fourth and final scheduled spacewalks for space shuttle Endeavour 's STS-134 mission on Friday morning, the U.S. National Aeronautics and Space Administration (NASA) announced.The seven-hour, 24-minute spacewalk completed by Mike Fincke and Greg Chamitoff at 7:39 a.m. EDT (1139 GMT) was the final spacewalk conducted by space shuttle astronauts before NASA turns over Endeavour and sister ships Discovery and Atlantis to museums. Space station crew will continue to make spacewalks for maintenance and repair tasks.At 5:02 a.m. (0902 GMT), Fincke and Chamitoff surpassed the 1, 000th hour astronauts and cosmonauts have spent spacewalking in support of space station assembly and maintenance. The milestone occurred four hours and 47 minutes into the spacewalk, the 159th in support of station assembly and maintenance, totaling 1,002 hours, 37 minutes.The astronauts completed their mission to stow the 50-foot-long boom on the station truss and work on some new installations to extend the space station's robotic arm. After that, shuttle commander Mark Kelly called Mission Control in Houston to mark the milestone -- after 12 years of efforts."Space station assembly is complete," Kelly said.It was the 248th spacewalk U.S. astronauts have conducted and the 118th from space station airlocks. Landing is scheduled for 2: 32 a.m. EDT (0632 GMT) on Wednesday at the Kennedy Space Center in Florida. Shuttle Atlantis is targeted to launch on July 8 for space shuttle's final flight.Endeavour lifted off on May 16 from the Kennedy Space Center in Florida, to deliver to the International Space Station a 2-billion- dollar, multinational particle detector known as the Alpha Magnetic Spectrometer (AMS).AMS, a particle physics detector, is designed to search for various types of unusual matter by measuring cosmic rays. Its experiments are designed to help researchers study the formation of the universe and search for evidence of dark matter, strange matter and antimatter.NASA's 30-year-old shuttle program is ending due to high operating costs. The Obama administration wants to spur private companies to get into the space taxi business, freeing NASA to focus on deep space exploration and new technology development.When the U.S. space shuttle program officially ends later this year, the Russian space program's Soyuz capsule will be the only method for transporting astronauts to and from the station.

HONG KONG, March 18 (Xinhua) -- After over a year's efforts, scientists from Shanghai and Hong Kong announced on Friday that they have completed the whole genomic sequencing work of Isaria cicada, a rare herb highly valued in traditional Chinese medicine, which will help facilitate its further development in medical and nutrition fields.It is the first time that the whole genomic sequence of Isaria cicada has been released, said the scientists from Shanghai Institute of Bio-Asia Life Science and the Hong Kong University of Science and Technology (HKUST), who participated in the research.The result was announced at the International Biomedical Scientists and Biotechnology Forum 2011 held in the day at the Hong Kong Science Park.According to the result, the genomic size of Isaria cicada, a medicine traditionally used to treat children's diseases, is about one eightieth of human genome, containing about 16,000 genes.The tests that had been done proved that Isaria cicada, with many high-quality genes not recognized or used by human beings yet, has been deeply involved in important life processes like metabolism, providing new ways for further development of Isaria cicad in bio-medical area, said a scientist from HKUST.The genome map will also help accelerate the artificial cultivation of Isaria cicada, enhancing its medicine and nutrition value and making it available in a larger market, according to the scientist.

ROME, May 26 (Xinhua) -- African swine fever, a viral disease deadly to pigs but harmless to human beings, is spreading beyond Russia and the Caucasus region into Europe, the United Nations' food agency said Thursday."African swine fever is fast becoming a global issue," said Juan Lubroth, chief veterinary officer for the Food and Agriculture Organization."It now poses an immediate threat to Europe and beyond. Countries need to be on the alert and to strengthen their preparedness and contingency plans," he said.The disease, for which there is currently no vaccine, was introduced into Georgia from southern Africa late in 2006. It entered through the Black Sea port of Poti, where garbage from a ship was taken to a dump where pigs came to feed, the FAO said.Strategies to tackle African swine fever include quarantine, on-farm security and other measures aimed at minimizing the risk of introduction and establishing of the disease.

HARARE, Feb. 9 (Xinhua) -- The two-day visit to Zimbabwe by Chinese Foreign Minister Yang Jiechi starting Thursday is an endorsement of relations between the Southern African country and China, local figures told Xinhua.Former Zimbabwean ambassador to China Chris Mutsvangwa said in an interview on Tuesday that Yang's visit will also boost economic relations between the two countries."The visit of a foreign minister is a big banner announcement to say that relations between Zimbabwe and China are reaching for a new level," he said."This is a visit which will mark a new diplomatic high watermark in Zimbabwe's international relations because to get the visit of an important and emerging super-power like China with such economic clout is a big vote of confidence on the part of Zimbabweans who have been pummeled by sanctions" imposed by the West.Yang, who will make the visit at the invitation of Zimbabwean Foreign Minister Simbarashe Mumbengegwi, is scheduled to meet President Robert Mugabe and other senior government officials.Mutsvangwa said the Chinese veto at the United Nations in 2008 was "a landmark diplomatic decision where it basically saved Zimbabwe from punitive sanctions instigated by an irate and sulky former colonial power.""So, now this visit will give an opportunity for Zimbabweans tofinally thank China for this act. But more important, cooperation in the economic field is beginning to gather pace because we have crossed the diplomatic and political travails which have been going on in the last 10 years and come out more united because the Chinese veto also enabled Zimbabweans to find accommodation among themselves and led to the GNU and GPA," Mutsvangwa said.China, together with Russia, vetoed the British initiative for full-scale UN sanctions against Zimbabwe, saying the Southern African Development Community (SADC) and the African Union (AU) should be given a chance to resolve the country's political problems.A SADC-driven initiative led to a Government of National Unity (GNU) following the signing of the Global Political Agreement (GPA) between Mugabe and then rivals Prime Minister Morgan Tsvangirai and Deputy Prime Minister Arthur Mutambara."So there is more national unity now among Zimbabweans. It is an opportune moment for us to tighten our relations with China so that we can explore cooperation in the more rewarding material areas of agriculture, mining, tourism and industrialization."There is clearly a lot of scope for cooperation between Zimbabwe and China so that Zimbabwe can quicken its modernization pace taking advantage of the stellar achievements of the Chinese in the above areas," Mutsvangwa said.He cited areas such as telecommunications, international logistics and the internet as being led by the Chinese.China Tobacco has also been on the fore-front reviving tobacco farming in Zimbabwe for the past five years.Mutsvangwa said shortages in the global cotton sector could spur better trade relations between the two countries and lead to more opportunities for Zimbabwean farmers.

WASHINGTON, April 6 (Xinhua) -- A study led by researchers at the University of Michigan (U-M) showed in animal studies that new cancer drug compounds they developed shrank tumors, with few side effects.The study, done in two mouse models of human cancer, looked at two compounds designed to activate a protein that kills cancer cells. The protein, p53, is inactivated in a significant number of human cancers. In some cases, it is because another protein, MDM2, binds to p53 and blocks its tumor suppresser function. This allows the tumor to grow unchecked. The new compounds block MDM2 from binding to p53, consequently activating p53."For the first time, we showed that activation of p53 by our highly potent and optimized MDM2 inhibitors can achieve complete tumor regression in a mouse model of human cancer," says lead study author Shaomeng Wang, director of the Cancer Drug Discovery Program at the U-M Comprehensive Cancer Center.Wang presented the study Wednesday at the American Association for Cancer Research 102nd annual meeting.Many traditional cancer drugs also activate p53 but they do so by causing DNA damage in both tumor cells and normal cells, causing side effects. These new MDM2 inhibitors activate p53 while avoiding the DNA damage common with other drugs. In this study, which was done in collaboration with Ascenta Therapeutics and Sanonfi-Aventis, researchers showed that these new drugs shrank tumors without significant side effects.Because p53 is involved in all types of human cancer, the new drug has potential to be used in multiple types of cancer. Further, the researchers also identified certain markers in tumors that predict which ones will be particularly sensitive to the MDM2 inhibitor, which would allow physicians to target the drug only to patients most likely to benefit.
