NEW YORK, April 13 (Xinhua) -- New York City Mayor Michael Bloomberg and former U.S. President Bill Clinton announced on Wednesday the merger of their environmental groups, hoping to make it the most prominent climate policy organization in the world.The new organization would combine C40, a coalition of international cities run by Bloomberg, and the Clinton Climate Initiative, a project of Clinton' s philanthropic foundation, into a single organization, which will focus on population-rich cities to address global warming."I am elated by this. I think we really have a chance to make a difference," said Bill Clinton during a press conference at Gracie Mansion, adding that "together we are proving it is possible to create jobs and grow economies through reduced emissions."C40 and the Clinton Climate Initiative both seek to cut carbon emissions through programs that reduce energy use in buildings, promote mass transit and reuse greenhouse gases emitted by landfills.The newly combined organization is said to have a budget of about 15 million U.S. dollars. The group will have main offices in New York, Los Angeles and London.

WASHINGTON, March 22 (Xinhua) -- A long-term study by Greek researchers has shown the effectiveness of replacing bone marrow, purposely destroyed by chemotherapy, with autologous (self) stem cells in treating people with aggressive forms of multiple sclerosis (MS).The study was published on Tuesday in Neurology, the medical journal of the American Academy of Neurology.For the treatment, chemotherapy drugs are used to kill all of the patient's blood cells, including the immune cells that are believed to be attacking the body's own central nervous system. Bone marrow stem cells removed from the patient are purified and transplanted back into the body, which saves life by replacing the blood cells and also is proposed to "reboot" the immune system.A human embryonic stem cell line derived at Stanford University is seen in this handout photo released to Reuters by the California Institute for Regenerative Medicine, March 9, 2009The study followed 35 people for an average of 11 years after transplant. The study involved people with rapidly progressive MS who had tried a number of other treatments for MS with little or no effect. All were severely disabled by the disease, with an average score of six on a scale of disease activity that ranges from zero being a normal neurological examination to 10 meaning death due to MS.A score of six means able to walk with a cane or crutch; a seven is mainly in a wheelchair. All had worsened by at least one point on the scale in the year prior to the transplant.After the transplants, the probability of participants having no worsening of their disease for 15 years was 25 percent. The probability was higher -- 44 percent -- for those who had active brain lesions, which are a sign of disease activity, at the time of the transplant.For 16 people, symptoms improved by an average of one point on the scale after the transplant, and the improvements lasted for an average of two years. The participants also had a reduction in the number and size of lesions in their brains. Two people (six percent) died from complications related to the transplant at two months and 2-1/2 years post-transplant.Study author Vasilios Kimiskidis, of Aristotle University in Thessaloniki, Greece, noted that more research is needed on this treatment, including studies that compare people receiving the treatment to a control group that does not receive the treatment."Keeping that in mind, our feeling is that stem cell transplants may benefit people with rapidly progressive MS," he said. "This is not a therapy for the general population of people with MS but should be reserved for aggressive cases that are still in the inflammatory phase of the disease."

BEIJING, Feb. 19 (Xinhua) -- As the traditional Spring Festival season ended two days ago, a new wave of post-holiday travel rush came to China's railway system, the Ministry of Railways (MOR) said Saturday.According to a statement from the MOR, the nation's railways carried 6.49 million passengers on Friday, the first day after the Lantern Festival which ended the festival season.The new wave of passengers mainly included students going back to school for the new semester and migrant workers returning to cities to start work. On Friday alone, 919,000 student passenger trips were made on railways, said the MOR.The ministry expected the travel volume and duration of the new peak to be similar to the previous year, with an average of more than 6 million railway passenger trips a daily.The MOR figures also showed that 166 million trips were made on railways since the Spring Festival travel rush began on Jan. 19, up 6 percent from the same period last year.

SAN FRANCISCO, May 25 (Xinhua) -- Micro-blogging service Twitter on Wednesday confirmed that it has bought TweetDeck, a London-based startup that develops application to help people organize information posted on Twitter."Today, we're pleased to announce that the TweetDeck team has joined Twitter," Dick Costolo, Twitter's chief executive officer (CEO), said in a blog post."This acquisition is an important step forward for us. TweetDeck provides brands, publishers, marketers and others with a powerful platform to track all the real-time conversations they care about," he added.Founded in 2008, TweetDeck now has a team of 15 and offers a real-time application that allows users to monitor abundance of information from social media services including Twitter in a single concise view."Change may well be inevitable, but we remain the same team, staying in London, with the same focus and products, and now with the support and resources to allow us to grow and take on even bigger challenges," Iain Dodsworth, founder and CEO of TweetDeck, noted in a separate blog post.The deal is a defensive move for Twitter aimed at preventing TweetDeck from being purchased by rivals, some analysts said.Financial terms of the transaction were not disclosed, but technology blog site TechCrunch and other U.S. media reported that Twitter paid 40 million to 50 million U.S. dollars.

LOS ANGELES, April 7 (Xinhua) -- Using NASA's Galaxy Evolution Explorer (GEE) satellite, U.S. astronomers are hunting for nearby, hard-to-see stars which could very well be home to the easiest-to-see alien planets, it was announced on Thursday.U.S. astronomers are ferreting out the new targets after the glare of bright, shining stars has frustrated most efforts at visualizing distant worlds, NASA's Jet Propulsion Laboratory (JPL) said.So far, only a handful of distant planets, or exoplanets, have been directly imaged. Small, newborn stars are less blinding, making the planets easier to see, but the fact that these stars are dim means they are hard to find in the first place."Fortunately, the young stars emit more ultraviolet light than their older counterparts, which makes them conspicuous to the ultraviolet-detecting GEE," JPL said in a press release."We've discovered a new technique of using ultraviolet light to search for young, low-mass stars near the Earth," said David Rodriguez, a graduate student of astronomy at University of Californian, Los Angeles. "These young stars make excellent targets for future direct imaging of exoplanets."Young stars, like human children, tend to be a bit unruly -- they spout a greater proportion of energetic X-rays and ultraviolet light than more mature stars. In some cases, X-ray surveys can pick out these youngsters due to the "racket" they cause. However, many smaller, less "noisy" baby stars perfect for exoplanet imaging studies have gone undetected except in the most detailed X-ray surveys. To date, such surveys have covered only a small percentage of the sky, according to JPL in Pasadena, Los Angeles.Rodriguez and his team figured that the GEE, which has scanned about three-quarters of the sky in ultraviolet light, could fill this gap.Astronomers compared readings from the telescope with optical and infrared data to look for the telltale signature of rambunctious junior stars. Follow-up observations of 24 candidates identified in this manner determined that 17 of the stars showed clear signs of youth, validating the team's approach, JPL said."The Galaxy Evolution Explorer can readily select young, low- mass stars that are too faint to turn up in all-sky X-ray surveys, which makes the telescope an incredibly useful tool," Rodriguez said in the release.
