WASHINGTON, March 30 (Xinhua) -- A trace amount of radioactive iodine has been found in a sample of milk from the west state of Washington, the U.S. Environmental Protection Agency and the Food and Drug Administration (FDA) said Wednesday.According to a joint statement from the two agencies, results from a screening sample taken March 25 from Washington detected 0.8 pCi/L of iodine-131, which is more than 5,000 times lower than the Derived Intervention Level set by the FDA.These types of findings are to be expected in the coming days and are far below levels of public health concern, including for infants and children, the statement said.Iodine-131 has a very short half-life of approximately eight days, and the level detected in milk and milk products is therefore expected to drop relatively quickly."Radiation is all around us in our daily lives, and these findings are a minuscule amount compared to what people experience every day. For example, a person would be exposed to low levels of radiation on a round trip cross country flight, watching television, and even from construction materials," said Patricia Hansen, an FDA senior scientist.

WASHINGTON, April 19 (Xinhua) -- The U.S. National Aeronautics and Space Administration (NASA) on Tuesday set April 29 as the launch date for Endeavour's final voyage.The date was announced Tuesday at the conclusion of a flight readiness review at Kennedy Space Center. During the meeting, senior NASA and contractor managers assessed the risks associated with the mission and determined the shuttle and station's equipment, support systems and personnel are ready.Liftoff time is 3:47 p.m. EDT (1947 GMT). It will be the 134th shuttle mission overall, the 25th for Endeavour and the 36th shuttle mission to the International Space Station.Endeavour will deliver to the station a 2-billion-dollar, multinational particle detector known as the Alpha Magnetic Spectrometer.Space shuttle Endeavour sits on launch pad 39A with the crew aboard minutes before mission managers scrubbed the launch again at Cape Canaveral, Florida, July 13, 2009.The spectrometer, also designated AMS-02, is a particle physics experiment module that is to be mounted on the station. It is designed to search for various types of unusual matter by measuring cosmic rays. Its experiments will help researchers study the formation of the Universe and search for evidence of dark matter and antimatter.Endeavour's two-week mission was led by Commander Mark Kelly. Other crew include Pilot Greg Johnson, NASA Mission Specialists Michael Fincke, Andrew Feustel and Greg Chamitoff and European Space Agency Mission Specialist Roberto Vittori. Astronauts are planning to step out on four spacewalks to do maintenance work and install new components.NASA's 30-year-old shuttle program is ending this year 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.Shuttle Atlantis is set for its final journey into space at the end of June. Its return to earth will mark the official end of the U.S. space shuttle program. After that, the Russian space program' s Soyuz capsule will be the only method for transporting astronauts to and from the station.

BEIJING, May 19 (Xinhuanet) -- LinkedIn said Wednesday that its stock will debut at 45 U.S. dollars per share, a higher price than the company was expecting even earlier this week, media reports said.The first major U.S. social networking firm to go public, LinkedIn jacked up its initial public offering (IPO) share price for 7.84 million shares to 45 dollars just a week after it first set a target of 32-35 dollars per share.It minted LinkedIn with a market value of more than 4 billion dollars, the highest for a U.S. Internet company taking its first bow on Wall Street since Google Inc. went public nearly seven years ago.The sale could bring in more than 354 million dollars. The company's shares are expected to begin trading on the New York Stock Exchange on Thursday under the symbol "LNKD".LinkedIn has more than 100 million members in over 200 countries and territories. In 2010, the company made 15 million dollars in profit on 243 million dollars in revenue, according to its SEC filing.LinkedIn's biggest shareholder is its founder and chairman, Reid Hoffman, who owns more than 21 percent of the company.

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.

LOS ANGELES, May 23 (Xinhua) -- NASA's Gravity Recovery And Interior Laboratory spacecraft (Grail) will begin final preparations for a launch on a Moon mission in late summer, the Jet Propulsion Laboratory (JPL) said on Monday.The dynamic duo will orbit the moon to determine the structure of the lunar interior from crust to core and to advance understanding of the thermal evolution of the moon, according to JPL in Pasadena, Los Angeles.After arriving at the Astrotech payload processing facility in Titusville, Florida last week, the Grail twins, known as Grail-A and Grail-B, were removed from their shipping containers Monday. Later this week, they will begin functional testing to verify their state of health, said JPL.The twins were shipped from Lockheed Martin Space Systems, Denver.Over the next four months at the Astrotech facility, the spacecraft will undergo final testing, fueling and packaging in the shroud that will protect them as the Delta II launch vehicle lifts them into space. The spacecraft will then be transported to the Cape Canaveral Air Force Station for installation atop the rocket that will carry them toward the moon, JPL said."We're only a few full moons away from a mission that will reveal clues not only into the history of the moon and Earth, but will provide important data for future lunar exploration," said Maria Zuber, Grail's principal investigator, based at the Massachusetts Institute of Technology.Grail will be carried into space aboard a United Launch Alliance Delta II Heavy rocket lifting off from Launch Complex-19 at the Cape Canaveral Air Force Station in Florida. The launch period opens Sept. 8, 2011, and extends through Oct. 19. For a Sept. 8 liftoff, the launch window opens at 5:37 a.m. PDT (8:37 a.m. EDT) and remains open through 6:16 a.m. PDT (9:16 a.m. EDT).Grail-A and Grail-B will fly in tandem orbits around the moon for several months to measure its gravity field in unprecedented detail.The mission will also answer longstanding questions about Earth' s moon, and provide scientists a better understanding of how Earth and other rocky planets in the solar system formed, according to JPL, which manages the Grail mission.
