BUDAPEST, June 25 (Xinhua) -- Visiting Chinese Premier Wen Jiabao made a five-point proposal here Saturday to enhance China's cooperation with countries in Central and Eastern Europe.When delivering a speech at the China-Central and East European Countries Economic and Trade Forum, Wen said China cherished its longstanding and deep friendship with the countries in the region."Over the past several decades, although the international situation and the domestic situations of both sides have undergone big changes, we have always enjoyed mutual respect, mutual trust, mutual understanding and mutual support," Wen said. Chinese Premier Wen Jiabao addresses the China-Central and Eastern European Countries Economic and Trade Forum in Budapest, Hungary, June 25, 2011.He said cooperation in various fields between the two sides had made tremendous progress, referring to the rapid growth of two-way trade, the burgeoning of mutual investment, the expansion of cooperation areas and the improvement of cooperation mechanisms.China encouraged its companies to "go global" and saw Central and Eastern Europe as a strategic priority, the Chinese leader said, adding that his current visit was "both a journey of friendship and a journey of cooperation."

BEIJING, June 14 (Xinhuanet) -- Having a pet at home during the first year of a child may halve the risk of developing allergic to them later in life, a new study suggests.The study was published in the journal Clinical & Experimental Allergy.Researchers from Henry Ford Hospital in Detroit assessed 566 boys and girls who were followed from birth until age 18. They found that boys who had dogs and teens who had cats during their first year of life had 50 percent less risk of developing pet allergies later.Lead researcher Ganesha Wegienka said: "This research provides further evidence that experiences in the first year of life are associated with health status later in life, and that early life pet exposure does not put most children at risk of being sensitised to these animals later in life."The researchers said that exposure to animals at other times in childhood didn't appear to be as significant as the first year.However, Wegienka cautioned that this study doesn't prove a cause-and-effect relationship between having a pet and avoiding allergies, just an association between those two factors."We don't want to say that everyone should go out and get a dog or cat to prevent allergies," she said."More research is needed, though we think this is a worthwhile avenue to pursue."

GENEVA, Aug. 19 (Xinhua) -- The World Health Organization (WHO) and the UN Children's Fund (UNICEF) started an emergency vaccination campaign in all accessible areas of South and Central Somalia, WTO spokesperson Tarek Jasarevic said here on Friday.In July 2011 alone, 1,019 suspected measles cases and 31 related deaths were reported in South and Central Somalia, representing 20 percent of all reported cases for this year.The major factors for a measles outbreak in Somalia are low coverage, malnutrition, population movements, and overcrowed internally displaced (IDP) camps."WHO fears that the measles outbreak could affect a high number of people, especially among the vulnerable IDPs whose overall health is already fragile," Jasarevic said.About 2.5 million children aged between 6 and 15 in 10 regions of South and Central Somalia, including children in Mogadishu, will be targeted during this campaign.

JERUSALEM, July 25 (Xinhua) -- A new study carried out by a Tel Aviv University researcher indicates that the common backache may not only be caused by bad positions or aging, but also by your genes.Prof. Gregory Livshits of the Sackler Faculty of Medicine says that genes play a major role in back pain, especially in the lower back, and in spinal deterioration.In a decade-long project with 2,500 identical and non-identical twins, Livshits found that, in one Arab family, the same back problems appeared in all the members of the family, whether young or old.According to the study, non-identical twins were three times more likely to have back pain, while identical twins were six times more likely to have the same back problems.Livshits believes the discovery of the link between back pains and genes could lead to much better treatment.The research was developed in collaboration with a team of scientists at Kings College, London, led by Prof. Tim Spector and Dr. Fran Williams and was recently published in the journal " Annals of the Rheumatic Diseases."In order to better investigate the genetic causes for one of the world most common pains, Livshits and his colleagues hope to put together an international consortium of research groups.

LOS ANGELES, July 27 (Xinhua) -- The Juno spacecraft of the National Aeronautics and Space Administration (NASA) arrived at its launch pad at the Cape Canaveral Air Force Station in Florida on Wednesday, ready for a mission to Jupiter to study the solar system, the Jet Propulsion Laboratory (JPL) said.The solar-powered, Jupiter-bound spacecraft was secured into place on top of its rocket at 10:42 a.m. EDT (7:42 a.m. PDT), said JPL in Pasadena, California.Juno will arrive at Jupiter in July 2016 and orbit its poles 33 times to learn more about the gas giant's interior, atmosphere and aurora, according to JPL."We're about to start our journey to Jupiter to unlock the secrets of the early solar system," said Scott Bolton, the mission 's principal investigator from the Southwest Research Institute in San Antonio, Texas. "After eight years of development, the spacecraft is ready for its important mission."Now that the Juno payload is atop the most powerful Atlas rocket ever made -- the United Launch Alliance Atlas V 551 -- a final flurry of checks and tests can begin and confirm that all is go for launch, according to JPL.The final series of checks begins Wednesday with an on-pad functional test. The test is designed to confirm that the spacecraft is healthy after the fueling, encapsulation and transport operations."The on-pad functional test is the first of seven tests and reviews that Juno and its flight team will undergo during the spacecraft's last 10 days on Earth," said Jan Chodas, Juno's project manager at JPL. "There are a number of remaining pre- launch activities that we still need to focus on, but the team is really excited that the final days of preparation, which we've been anticipating for years, are finally here. We are ready to go. "The launch period for Juno opens Aug. 5, 2011, and extends through Aug. 26. For an Aug. 5 liftoff, the launch window opens at 11:34 a.m. EDT (8:34 a.m. PDT) and remains open through 12:43 p.m. EDT (9:43 a.m. PDT), JPL said.Managed by JPL, the Juno mission is part of the New Frontiers Program managed at NASA's Marshall Space Flight Center in Huntsville, Alaska.
