MOSCOW, Aug. 3 (Xinhua) -- Two Russian cosmonauts manually launched a mini satellite from the International Space Station ( ISS) during a six-hour spacewalk Wednesday, said the Mission Control center near Moscow.Sergei Volkov and Alexander Samokutyayev, who started the spacewalk with a 20-minute delay, found the 30-kg Kedr has lost one of its two antennas during its delivery to the ISS in January. After consulting with the Mission Control, they have decided to launch the device anyway, Interfax news agency reported.The Kedr satellite, which was made by Russian students, was created to transmit from the orbit greetings in 15 languages about the 50th anniversary of Yuri Gagarin's first space flight. It could also photograph the Earth and re-transmit information from the ISS equipment.During the spacewalk, the cosmonauts were expected to install new stream video equipment on the station's outer surface, and to take pictures holding photos of the founders of Russian space explorations, including Konstantin Tsiolkovski, Sergei Korolyov and Yuri Gagarin.

XICHANG, Sichuan, July 27 (Xinhua)-- China successfully launched an orbiter into space at 5:44 a.m. Beijing Time Wednesday, as a part of its indigenous satellite navigation and positioning network known as Beidou, or Compass system, sources with the launch center said.The orbiter,launched from the Xichang Satellite Launch Center in southwestern Sichuan Province, was boosted by a Long March-3A carrier rocket into a geostationary orbit.China started to build up its own satellite navigation system to break its dependence on the U.S. Global Positioning System (GPS) in 2000.A Long March-3A carrier rocket lifts off at the Xichang Satellite Launch Center in southwest China's Sichuan Province, July 27, 2011. China successfully launched into space a ninth orbiter for its independent satellite navigation and positioning network known as Beidou, or Compass System here early WednesdayBetween October 2000 and May 2003, the country set up a regional satellite navigation system after launching three Beidou geostationary satellites.The system was known as Beidou-1 and is said to have played an important role in the rescue efforts following the devastating earthquake in May 2008 in Wenchuan as it provided the only channel connecting the quake-hit area and the outside.The Beidou-1 system can not meet growing demand, so a better functional Beidou-2 regional and global navigation system will be set up, Qi Faren, former chief designer for Shenzhou spaceships said in an interview with Xinhua early this year.From April 2007 to April this year, China launched another eight orbiters to form its Beidou-2 system, which will eventually consist of 35 satellites.The network will provide satellite navigation, time and short message services for Asia-Pacific regions by 2012 and global services by 2020.

COPENHAGEN, May 29 (Xinhua) -- The number of confirmed E.coli cases has risen to 11 with at least another eight persons suspected of having the intestinal infection in Denmark, according to Denmark's National Serum Institute on Sunday.Five of the confirmed cases show symptoms of kidney failure which marks an advanced stage of the sickness, the institute said.Danish cucumbers are suspected of helping spread the E. coli bacteria believed to be causing a deadly outbreak of intestinal infection in Denmark and Germany, local media reported Sunday.The Danish cucumbers were mixed in Germany with cucumbers originating in the Netherlands, making it difficult to determine if Danish cucumbers are in fact contaminated.Denmark's Veterinary and Food Administration (DVFA) had earlier said the suspicion against Danish cucumber was "vague", but advised Danish consumers not to eat raw tomatoes, lettuces and cucumbers from Germany, and cucumber from Spain.It is now checking Danish cucumbers for traces of E. coli with results expected on Tuesday.Some Danish retailers have now removed these products from their supermarket shelves. And the Danish branch of fast-food chain McDonald's announced Saturday that it was dropping fresh cucumbers from its menu until further notice.The infection, which is food-borne, can be caused by eating raw or uncooked foods such as vegetables contaminated with the E. coli bacteria.Symptoms of infection include mild fever, bloody diarrhea and vomiting, and can last five to seven days. It can prove fatal in the very young, sick, or elderly.

SHENZHEN, June 4 (Xinhua) -- Chinese scientists who have fully sequenced the genome of the new E. Coli spreading through Europe said Saturday they found genes in the bacteria that gave it resistance to eight classes of antibiotics.Researchers with the Beijing Genomics Institute, the world's largest DNA sequencing center, have found genes in the newly identified 0104 strain of E. Coli bacteria that made it resistant to major classes of antibiotics including sulfonamide, cephalothin, penicillin and streptomycin.This helped explain why doctors in Europe had difficulties in fighting the bug that has killed 18 people and sickened nearly 2,000, BGI's major research arm in Shenzhen said on its website Saturday.This would help doctors choose right medicines for the treatment, it said.The researchers are developing a diagnostic kit which will be used to detect the bacteria and prevent the epidemic from spreading further.The Chinese researchers obtained DNA samples of the bacteria from collaborating scientists in Germany and fully sequenced its genome in three days this week.They announced on Thursday the E. Coli spreading through Europe was "a new strain of bacteria that is highly infectious and toxic".The 0104 strain of E. Coli was not previously involved in any E. Coli outbreaks. However, it has 93 percent sequence similarity with the EAEC 55989 E. Coli strain which was isolated in the Central African Republic and known to cause seriously diarrhea, BGI said.The source of the outbreak is unknown, but scientists say it is highly likely to have originated in contaminated vegetables or salad in Germany.

HOHHOT, July 8 (Xinhua) -- The 3rd Happy Grassland Fitness Day will kick off 16 August in Chifeng city, north China's Inner Mongolia Autonomous Region.12 cities and leagues in the region will send athletes to compete in 4 sports including Mongolian wrestling, Mongolian archery, table tennis and badminton.The activity was jointly held by the regional sports department and Chifeng sports department.
