BERLIN, June 9 (Xinhua) -- A 57-year-old man died of E. coli infection in Germany's Frankfurt Thursday, pushing the death toll from the bacteria to 30.The man had traveled with his wife to the city of Hamburg, an epicenter of the outbreak, Frankfurt authority said.Another two deaths were reported in the state of Lower Saxony, including a 68-year-old man and a 20-year-old woman, while more than 2,800 people in 14 countries have been infected since the deadly E. coli outbroke.German researchers detected again the deadly strain o104 of E. coli on the scraps of cucumbers in a dustbin in the eastern city of Magdeburg in the state Saxony-Anhalt on Wednesday.German health minister Daniel Bahr expressed his cautious hope for the disease on Wednesday as the number of new infection is clearly going down.But he also admitted there will be new cases and more deaths have to be expected, as Germany's national disease control centre, the Robert Koch Institute reported more than 300 infection in Germany on the same day.The Robert Koch Institute also noticed the declining trend in new cases but it was not clear whether this was caused by people staying away from vegetables or the outbreak was truly waning.

BEIJING, Aug. 22 (Xinhuanet) -- Researchers have discovered how a human egg captures an incoming sperm for fertilization, paving the way to help couples suffering from infertility, according to media reports on Monday.An international team of researchers found that a sugar chain known as the sialyl-lewis-x sequence (SLeX) makes the outer coat of the egg “sticky,” which has proven to be helpful in binding the egg and the sperm.As a result, this observation has filled in a huge gap in the understanding of fertility and provides hope for ultimately helping couples who currently cannot conceive.Scientists and doctors know that a sperm identifies an egg when proteins on the head of the sperm match and bind to a series of specific sugars in the egg’s outer coating. With a successful match of proteins, the outside surfaces of the sperm and egg then bind together before merging, which is then followed by delivery of sperm’s DNA into egg.To identify this molecules, the researchers used ultra-sensitive mass-spectrometric imaging technology to observe and identify which molecules are most likely to be key in the binding process.They experimented with a range of synthesised sugars in the laboratory and found that it is SLeX that specifically binds sperm to an egg.According to the World Health Organisation, infertility affects about 15 percent of reproductive-aged couples around the world and almost one in every seven couples in Britain has problems conceiving a child for various reasons.

New York, Sept. 23 (Xinhua) -- A Chinese scientist was presented a prestigious U.S. award on Friday for the discovery of artemisinin, a drug therapy for malaria that has saved millions of lives across the globe, especially in the developing world. Pharmacologist Tu Youyou, 81, became the first scientist on the Chinese mainland to win Lasker Award, known as "America's Nobels" for their knack of gaining future recognition by the Nobel committee.Tu, a scientist at the China Academy of Chinese Medical Sciences in Beijing, pioneered a new approach to malaria treatment that has benefited hundreds of millions of people and promises to benefit many times more. By applying modern techniques and rigor to a heritage provided by 5000 years of Chinese traditional practitioners, she has delivered its riches into the 21st century."Not often in the history of clinical medicine can we celebrate a discovery that has eased the pain and distress of hundreds of millions of people and saved the lives of countless numbers of people, particularly children, in over 100 countries," Lucy Shapiro, a member of the award jury and professor of Stanford University, said while describing Tu' s discovery.Shapiro said the discovery, chemical identification, and validation of artemisinin, a highly effective anti-malarial drug, is largely due to the "scientific insight, vision and dogged determination" of Professor Tu and her team. She thought Professor Tu's work has provided the world with arguably the most important pharmaceutical intervention in the last half century."The discovery of artemisinin is a gift to mankind from traditional Chinese medicine," Tu said while receiving the award. "Continuous exploration and development of traditional medicine will, without doubt, bring more medicines to the world."

WASHINGTON, July 12 (Xinhua) -- Two U.S. astronauts stepped out the International Space Station on Tuesday to retrieve a failed ammonia pump, which is the last spacewalk of the shuttle era, NASA announced.Space station astronauts Mike Fossum and Ron Garan completed the six-hour, 31-minute spacewalk at 3:53 p.m. EDT (1953 GMT). The duo retrieved a pump module from an external stowage platform on station and store it in shuttle Atlantis' cargo bay for return to Earth.The pump module failed in 2010, shutting down half of the space station's cooling system. Engineers will evaluate the module to determine the cause of the failure and plan to refurbish it for use as a spare.The astronauts also attached a Robotic Refueling Module experiment to the space station, which aims to test technologies for repairing and refueling satellites in space.It was the 249th spacewalk by U.S. astronauts and the 160th spacewalk in support of space station assembly and maintenance, totaling 1009 hours, nine minutes.Atlantis lifted off on Friday morning from Kennedy Space Center in Florida, on the 135th and final flight in NASA's shuttle program. Its return to the earth later this month will mark the end of the 30-year shuttle program.

BEIJING, June 26 (Xinhua) -- A drama honoring an archivist who had devoted himself to the Chinese People's Liberation Army (PLA)'s archive work was staged Saturday evening in Beijing.The drama, "Sheng Ming Dang An," or "Archives of Life," tells the life story of Liu Yiquan who had worked as a file clerk and later a consultant at the PLA Archives for about 38 years.Liu had collected more than 830,000 pieces of military archives, which was regarded as a special contribution to the army. Li Changchun (L, front), a member of the Standing Committee of the Political Bureau of the Communist Party of China (CPC) Central Committee, congratulates actors on the successful performance of drama "life archives" in Beijing, capital of China, June 25, 2011.Despite being diagnosed with terminal cancer in 2008, Liu continued to work hard. He died on Jan. 28, 2010, at the age of 59.Li Changchun, a Standing Committee member of the Political Bureau of the Communist Party of China (CPC) Central Committee, joined the audience of the drama on Saturday.Li later said the drama was touching and significant in reflecting the model role of CPC members ahead of the 90th founding anniversary of the CPC.Liu Yiquan was also honored by the U.S. military authorities for his role in helping identify some key documents that led to the repatriation of the remains of the United States personnel who disappeared during and after the Korea War (1950-1953).
