BEIJING, Feb. 24 (Xinhua) -- Chinese Premier Wen Jiabao attended the opening ceremony of the China-EU Year of Youth in Beijing on Wednesday, encouraging young people from China and the EU to build a brighter future for bilateral strategic partnerships.Joining over 500 young people from China and the EU in the Capital Museum in downtown Beijing, Wen said that the year-long youth exchange campaign was the first theme year between China and the EU since the establishment of diplomatic ties, and is also the largest-ever China-EU cultural exchange program."This has revealed that our relations will be more vibrant in the future and full of hopes," he added.China and the EU are in a vital period for deepening cooperation, Wen said, calling on young people from both sides to consider and explore ways to share opportunities, meet challenges and seek common development, which has benefits for China, the EU and the world.Wen hopes that young people from both sides would always be brave in pursuing innovation and the truth. He also encouraged them to learn from each other in a frank and open spirit, in a bid to jointly create a better future for China-EU ties.A video speech from European Commission President Jose Manuel Barosso was aired at the ceremony. He said that the Year of Youth offers an interactive platform for European and Chinese young people to enhance mutual understanding and friendship and also inject vitality to China-EU relations.Premier Wen and Barroso jointly initiated The China-EU Year of Youth during the 12th EU-China summit held in 2009.Along with the opening ceremony in Beijing, Chinese and European youth were immersed in two-day discussions on topics such as culture, education, volunteering, creativity and environmental protection starting on Tuesday."We had excellent discussions on possible cooperation projects, ranging from environmental protection, world heritage to art and intellectual property," said Pierre Arlaud, a member of an EU youth delegation that arrived in Beijing on Monday to participate in the opening ceremony."I can feel there is a strong will from both sides to deepen understanding and forge a stronger partnership," he added.The opening ceremony was the first in a series of exchange activities that will be held throughout the year in China and Europe. The events include cultural seminars, volunteer service conferences, youth summer camps and TV debates.The year-long program was co-hosted by the All-China Youth Federation and the European Commission. The initiative aims to promote intercultural dialogue and strengthen mutual understanding and friendship between young people in China and the EU, as well as encouraging them to support the development of China-EU relations.

WASHINGTON, May 11 (Xinhua) -- Researchers at Brigham and Women 's Hospital (BWH), a teaching affiliate of Harvard Medical School, have identified a human lung stem cell that is self-renewing and capable of forming and integrating multiple biological structures of the lung. This research will be published Thursday in the New England Journal of Medicine."This research describes, for the first time, a true human lung stem cell. The discovery of this stem cell has the potential to offer those who suffer from chronic lung diseases a totally novel treatment option by regenerating or repairing damaged areas of the lung," said the study's corresponding author Piero Anversa, who is also director of the Center for Regenerative Medicine at the hospital.Using lung tissue from surgical samples, researchers identified and isolated the human lung stem cell and tested the functionality of the stem cell both in vitro and in vivo. Once the stem cell was isolated, researchers demonstrated in vitro that the cell was capable of dividing both into new stem cells and also into cells that would grow into various types of lung tissue. Next, researchers injected the stem cell into mice with damaged lungs. The injected stem cells differentiated into new bronchioles, alveoli and pulmonary vessel cells which not only formed new lung tissue, but also integrated structurally to the existing lung tissue in the mice.The researchers define this cell as truly "stem" because it fulfills the three categories necessary to fall under stem cell categorization: first, the cell renews itself; second, it forms into many different types of lung cells; and third, it is transmissible, meaning that after a mouse was injected with the stem cells and responded by generating new tissue, researchers were then able to isolate the stem cell in the treated mouse, and use that cell in a new mouse with the same results."These are the critical first steps in developing clinical treatments for those with lung disease for which no therapies exist. Further research is needed, but we are excited about the impact this discovery could have on our ability to regenerate or recreate new lung tissues to replace damaged areas of the lungs," said Joseph Loscalzo, chair of the Department of Medicine at BWH and co-author.

SAN FRANCISCO, May 3 (Xinhua) -- Microsoft announced on Tuesday that its Bing search engine will become the default search and mapping application on Blackberry phones.Microsoft Chief Executive Officer Steve Ballmer announced the partnership with Research in Motion (RIM), which makes Blackberry phones, at the Blackberry World Conference in Orlando, Florida, according to a Microsoft blog post.Ballmer said Microsoft would invest uniquely in the Blackberry platform in addition to its own Windows Phone platform."Bing will be deeply integrated at the BlackBerry OS (operating system) level," Ballmer said.Central to the collaboration, Blackberry devices will use Bing as the preferred search provider in the browser, and Bing will be the default search and map application for new devices presented to mobile operators, both in the United States and internationally, said Microsoft's Bing team in the blog post.Meanwhile, Bing is also shipping as the default search experience and map application for the newly released Blackberry Playbook, a RIM tablet computer which made market debut on April 19.On Tuesday's Blackberry conference, Ballmer called Google's Android ecosystem "chaos" and the Apple iOS "limited" before he hailed Windows Phone 7 and Blackberry. Microsoft and RIM are both competing with Apple, which makes the iPhone and iPad, and Google, which makes the Android operating system for smartphones and tablets in the booming mobile device market.

LOS ANGELES, May 25 (Xinhua) -- NASA project managers bade farewell to the Mars rover Spirit on Wednesday after sending a final set of commands to the stranded vehicle.This marks the completion of one of the most successful missions of interplanetary exploration ever launched, NASA's Jet Propulsion Laboratory (JPL) said."Last night, just after midnight, the last recovery command was sent to Spirit," said John Callas, the Mars Exploration Rover Project manager at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, Los Angeles."It would be an understatement to say this was a significant moment. Since the last communication from Spirit on March 22, 2010, as she entered her fourth Martian winter, nothing has been heard from her."NASA has tried in vain to regain communication with Spirit since it got stuck in sand about two years ago. The rover last communicated on March 22, 2010, as Martian winter approached and the rover's solar-energy supply declined.NASA checked frequently in recent months for possible reawakening of Spirit as solar energy available to the rover increased during Martian spring, but to no avail.A series of additional re-contact attempts ended on Wednesday, designed for various possible combinations of recoverable conditions, according to JPL."Our job was to wear these rovers out exploring, to leave no unutilized capability on the surface of Mars, and for Spirit, we have done that," said Callas.

SAN FRANCISCO, April 5 (Xinhua) -- Apple Inc.'s iPad 2 has topped the ratings by Consumer Reports, an influential U.S. magazine for product reviews, in the latest tests of the 10 most- promising tablet computers.According to the ratings released on Tuesday, the Apple iPad 2 with Wi-Fi plus 3G (32G), which is priced at 730 U.S. dollars, topped the ratings, scoring "excellent" in nearly every category.Besides several models from Apple, other brands tested include Archos, Dell, Motorola, Samsung and Viewsonic. Each tablet was evaluated on 17 criteria, including touch-screen responsiveness, versatility, portability, screen glare and ease of use."So far, Apple is leading the tablet market in both quality and price, which is unusual for a company whose products are usually premium priced," Paul Reynolds, electronics editor at Consumer Reports, said in a statement.The Motorola Xoom, whose price is 800 dollars, stood out as the iPad 2's main rival. It boasts several features that the iPad lacks, including a built-in memory card reader and support for the Flash videos.The first-generation iPad, priced at 580 dollars, also outscored many of the other models tested but tied with the Motorola Xoom, according to tests by Consumer Reports.
