BERLIN, June 14 (Xinhua) -- A two-year-old boy became the first child to be killed by the deadly E. coli in Germany on Tuesday, officials said.To date, the terrifying EHEC infection has claimed 36 lives in Germany and one in Sweden.The child, from the northern town of Celle, died in hospital in Hanover of kidney failure and abnormal breakdown of red blood cells, two extreme symptoms of the infection with enterohaemorrhagic E. coli (EHEC), authorities in the state of Lower Saxony said.The boy became the youngest known fatal victim since the outbreak of E. coli in May. His father and 10-year-old brother were also infected with the deadly bacteria, but are recovering, doctors told a local newspaper.The Robert Koch Institute, Germany's national disease prevention and control agency, said on Tuesday that a total of 3, 235 cases had been reported in the country. Among them, 782 people are suffering from haemolytic uraemic syndrome (HUS), a life- threatening illness arising from E. coli, which would destroy human kidney and nervous system.The institute added that the number of new infections is declining sharply in recent days, with only seven reported on Tuesday.German authorities announced on Friday that bean sprouts from a farm in northern Germany were one source of the outbreak, and dropped the previous warning against eating raw cucumbers, tomatoes and lettuce. However, the food panic has caused losses worth hundreds of millions of dollars for European farmers.

BEIJING, June 12 (Xinhua) -- A senior Chinese official has called the country's police to better serve the people when the Communist Party of China (CPC) is meeting the 90th founding anniversary.Zhou Yongkang, member of the Standing Committee of the Political Bureau of the CPC Central Committee, made the remark on Sunday evening in meeting with top 10 favorite police officers selected through a nationwide vote.The Ministry of Public Security (MOPS) and the China Central Television have jointly conducted My Favorite Police Officer Competition in the past eight years.This year's winners include 75-year-old detective Wu Guoqing, network security police officer Li Qing from Jiangsu Province, traffic police officer Wu Hao of Miao Nationality from Hunan Province, female SWAT team leader Pan Qin from Guizhou Province.Zhou said that this year's competition attracted more than 150 million online voters which means more and more people are supporting the activity, and all winners should cherish the honor and better serve the people on their own posts.The official called on police officers around the country to learn from the 10 favarite officers and other winners in the competition who have all made outstanding contribution to the security of the people and society.

WASHINGTON, Sept. 14 (Xinhua) -- The U.S. space agency NASA unveiled plans on Wednesday for a deep space rocket to carry astronauts to the moon, Mars and other destinations beyond the International Space Station.The Space Launch System, or SLS, will be designed to carry the Orion Multipurpose Crew Vehicle, as well as important cargo, equipment and science experiments to Earth's orbit and destinations beyond. Additionally, the SLS will serve as a backup for commercial and international partner transportation services to the International Space Station."This launch system will create good-paying American jobs, ensure continued U.S. leadership in space, and inspire millions around the world," NASA Administrator Charles Bolden said in a statement. "President Obama challenged us to be bold and dream big, and that's exactly what we are doing at NASA. While I was proud to fly on the space shuttle, kids today can now dream of one day walking on Mars."The SLS rocket will incorporate technological investments from the Space Shuttle program and the Constellation program in order to take advantage of proven hardware and cutting-edge tooling and manufacturing technology that will significantly reduce development and operations costs.The first developmental flight, or mission, is targeted for the end of 2017, according to NASA.

BEIJING, July 25 (Xinhuanet) -- Apple is planning a third, even larger Shanghai store, as well as dozens of other stores throughout China, to cope with huge crowds at its flagship store and a branch, according to media reports Monday.Apple says its Chinese outlets -- two in Beijing and two in Shanghai -- are the four most heavily trafficked Apple stores in the world. They also generate the most revenue. Apple’s push into China shows the depth of the country’s fast-growing economy, and shows that with products not so easy to counterfeit, Chinese consumers are willing to pay a premium.For the first three quarters of Apple’s fiscal year, revenue in China and its Taiwan, Hong Kong was 8.8 billion dollars -- six times that of a year earlier. China has become the second-largest market, after the United States, for apps that run on the smartphone and tablet, according to Distimo, a Dutch company that tracks the popularity of apps.In addition, Apple has been eager to team up with state-run telecom companies, which looks after mobile phone subscriptions.

WASHINGTON, June 16 (Xinhua) -- Cells in the human body are constantly being exposed to stress from environmental chemicals or errors in routine cellular processes. While stress can cause damage, it can also provide the stimulus for undoing the damage. New research by a team of scientists at the University of Rochester has unveiled an important new mechanism that allows cells to recognize when they are under stress and prime the DNA repair machinery to respond to the threat of damage.Their findings will be published Friday in journal Science. Cells in the human body are constantly being exposed to stress from environmental chemicals or errors in routine cellular processes. While stress can cause damage, it can also provide the stimulus for undoing the damage.The scientists, led by biologists Vera Gorbunova and Andrei Seluanov, focused on the most dangerous type of DNA damage -- double strand breaks. Unrepaired, this type of damage can lead to premature aging and cancer. They studied how oxidative stress affects efficiency of DNA repair. Oxidative stress occurs when the body is unable to neutralize the highly-reactive molecules, which are typically produced during routine cellular activities.The research team found that human cells undergoing oxidative stress synthesized more of a protein called SIRT6. By increasing SIRT6 levels, cells were able to stimulate their ability to repair double strand breaks. When the cells were treated with a drug that inactivated SIRT6, DNA repair came to a halt, thus confirming the role of SIRT6 in DNA repair. Gorbunova notes that the SIRT6 protein is structurally related to another protein, SIR2, which has been shown to extend lifespan in multiple model organisms."SIRT6 also affects DNA repair when there is no oxidative stress," explains Gorbunova. "It's just that the effect is magnified when the cells are challenged with even small amounts of oxidative stress."SIRT6 allows the cells to be economical with their resources, priming the repair enzymes only when there is damage that needs to be repaired. Thus SIRT6 may be a master regulator that coordinates stress and DNA repair activities, according to Gorbunova.
