BEIJING, March 7 (Xinhua) -- The Chinese currency Renminbi (RMB), or the yuan, on Monday strengthened to an all-time high of 6.5651 per U.S. dollar, according to the China Foreign Exchange Trading System.Monday's central parity rate of the RMB against U.S. dollar was 20 basis points lower than the previous record of 6.5671 set on last Friday.The yuan has appreciated 3.84 percent since June 19 last year when the People's Bank of China, the central bank, announced it would further reform the exchange rate formation mechanism to improve its flexibility.On China's foreign exchange spot market, the yuan can rise or fall 0.5 percent from the central parity rate each trading day.The central parity rate of the RMB against the U.S. dollar is based on a weighted average of prices before the opening of the market for each business day.

BEIJING, May 14 (Xinhua) -- From 24-hour complaint hotlines to instant additive detectors, local governments in China are striving to battle the illegal use of food additives following a string of food scandals.According to a statement released Saturday by the office of the food safety commission under the State Council, China's Cabinet, governments in Beijing, Shanghai, Zhejiang and Guangdong have incorporated the local food safety situation into the evaluation of officials' work, while ordering strengthened and coordinated food safety supervision at city and county levels.Many provinces and autonomous regions are distributing educational information through local media to promote, among the local population, the awareness of food safety and the harm of banned food additives, stressing severe punishment in the hope of intimidating potential violators.Certified food additives are displayed on shelves at a store that sells food additives in Beijing, capital of China, April 22, 2011.Law enforcement departments in Chongqing, Guangdong, Liaoning and Hunan have punished violators involved in a series of food scandals which included "poisonous bean sprouts," "inked vermicelli" and "dyed peppers," according to the statement.The document did not provide details on these cases.Meanwhile, governments are figuring out new measures to stem food violations.For instance, the provincial government of northeastern Jilin has set up round-the-clock hotlines for food safety complaints and recruited 1,300 voluntary food safety supervisors who go deep into communities for clues on potential food scandals.Supervisors in southern Guangxi Zhuang Autonomous Region were equipped with additive detecting devices, which are reportedly able to check 27 kinds of illegal food additives "quickly and correctly," including melamine and clenbuterol, a kind of fat-burning drug used by violators to feed pigs to prevent them from accumulating fat.The municipal government of Beijing stipulates that companies found to have committed food violations in the past would be limited in investing in the municipality, while principals responsible for the wrongdoings will be banned from food manufacturing and distribution businesses.Beijing also requires restaurants to inform customers of all food additives contained in their self-made beverages and food sauces by posting the lists in menus or other public places. The lists should also be reported to supervisory departments.According to the statement, the Ministry of Agriculture has sent five teams to various regions, including Hebei, Jilin and Heilongjiang to inspect local food safety conditions.Vice Premier Li Keqiang warned last month of the great harm caused by illegal additives in food during a high-profile national meeting, promising a "firm attitude, iron-handed measures and more efforts" in dealing with the problem."Once such a case surfaces, it has an extensive social impact and easily causes a ripple effect, so we must attach great importance to it," Li said, adding that severe penalties must be imposed on violators to "let the violators pay dearly" and send a message to others.A high-profile, nationwide fight against the illegal use of additives in food was then launched to intensify supervision, upgrade safety standards and greatly increase penalties for violators.The moves came following a series of scandals including steamed buns dyed with unidentified chemicals, as well as the use of illegal cooking oil, known as "gutter oil."In one of the latest cases, police detained 96 people for producing, selling or using meat additives and confiscated over 400 kg of clenbuterol, widely known in the country as "lean meat powder," in central Henan Province.The action followed a scandal revealed in March when the country's largest meat processor, Shuanghui Group, was forced to issue a public apology for its clenbuterol-tainted pork products.

You can think of NASA's Discovery program as a sort of outer-space American Idol: every few years the agency invites scientists to propose unmanned planetary missions. The projects have to address some sort of fundamental science question, and (this is the tough part) they have to be relatively cheap to pull off — say, half a billion dollars or so. Then the proposals go through a grueling competition before judges who aren't as nasty as Simon Cowell but who are every bit as tough. The one left standing at the end gets the equivalent of a recording contract: NASA supplies the funding and the launch vehicle, and away the winner goes — to orbit Mercury, as the Messenger spacecraft is doing right now; or to rendezvous with a couple of asteroids, as the Dawn mission will start doing this July; or to smash into a comet on purpose, a feat achieved by Deep Impact in 2005, a mission not to be confused with the movie of the same name. Now it's time for the next contenders. NASA has just announced that the first round of the latest Discovery competition is over, with three entries out of 28 moving on to the finals. They are, in increasing distance from Earth: the Geophysical Monitoring Station (GEMS) lander, which would use seismometers to study the interior of Mars; the Comet Hopper, which would do just that, leaping from place to place across the surface of Comet 46P/Wirtanen to see how different parts of the tumbling body react to heating by the sun; and the Titan Mare Explorer (TiME), which would plop into a sea of liquid hydrocarbons on Saturn's moon Titan — the first oceangoing vessel ever to set sail on another world. If you had to come up with a theme that ties all three missions together, it would be "origins." The Titan explorer, for example, will be studying a place that — in a crude way, at least — resembles the early planet Earth at a time when life arose here. Titan, with a thick atmosphere and a bizarro-world form of weather featuring toxic winds and hydrocarbon rain, is home to a mix of complex chemistry, complete with organic molecules. The oceans provide a medium in which the molecules can move around and interact with each other. It's even conceivable, though clearly a long shot, that some form of microscopic life already exists on this frigid moon. The Mars lander, by contrast, would visit a place where the seas — plain water in this case — vanished long ago. But the mission of GEMS goes far deeper than that. By analyzing Marsquakes on the Red Planet, GEMS will try to get a handle on what the interior of Mars is like. Scientists don't currently know whether the planet's core is liquid, like Earth's, or solid, or some mushy consistency in between. It all depends on how efficiently Mars has cooled since it formed 4.5 billion years ago, and that depends in turn on the planet's internal structure. "That's the mission," says Bruce Banerdt, of NASA's Jet Propulsion Laboratory, the lead scientist for GEMS. "We want to understand how Mars was built." Along with sensitive seismographic equipment, GEMS will drill down about 20 ft. (6 m) with a thermometer-equipped probe, trying to figure out how quickly the temperature rises with depth. "That will let us extrapolate all the way down to the center," Banerdt says, "which will tell us how fast Mars is cooling."

LOS ANGELES, May 20(Xinhua)-- Peter, a Chinese American who works for the post office in Rosemead, California, said he has been attacked by dogs twice in the past 10 years while delivering mails.He said as a mail carrier, he has to walk door to door to put mails into the mailboxes of the residents, and many times the owners were not at home but their dogs were too loyal to their duties and would see mail carriers like him as intruders."It is dangerous to be a mail carrier. The enemy is not humans but animals like dogs who have been generally seen as human's best friends," Peter, who asked not to identify his full name, told Xinhua.Mail carriers in the United States feel the real danger of being attacked by dogs while delivering mails door by door.Statistics released by the U.S. Post Office showed that 5,669 postal employees were attacked by dogs in 2010 in the United States. That's an average of 11 dog attacks every delivery day, and that figure does not include the number of threatening incidents that did not result in injury.Los Angeles is the third most dangerous city in the U.S. when it comes to being a mail carrier with 44 mail carriers being attacked by dogs in 2010, according to the U.S. Post Office.San Diego in California and Columbus in Ohio tied for second place, each logging 45 dog attacks. Houston in Texas is the most dangerous city in the U.S. for mail carriers with 62 attacks in 2010.On May 25, 2010, Eddie Lin, a 33-year old Chinese American postal carrier in San Diego, was attacked by a dog while delivering mail, his head hit on the ground and died 10 days later. His death angered his family and the whole community.The daughter of the dog's owner, who identified herself as Eva, said the incident has devastated her father."We feel really bad," Eva told the local press in an interview. "It's just killing my Dad," she added.On Sept. 30, 2010, a German Shepard and a Pitbull mix attacked Hu Ruiz, a 10-year veteran of the U.S. Postal Service. He luckily recovered from puncture wounds on his arms after the two dogs attacked him as he made deliveries along Camden Avenue in San Jose, California.It is not the problem for the mail carriers only. Dogs attack other people too. Statistics showed that there are more than 4.7 million Americans bitten by dogs nationwide annually.
