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.

CHICAGO, Jan. 20 (Xinhua) -- Chinese President Hu Jintao arrived here on Thursday afternoon from Washington, after meetings with U.S. President Barack Obama on major bilateral and world issues.During their talks Wednesday, the two leaders agreed to build a China-U.S. cooperative partnership based on mutual respect and mutual benefit.In Chicago, Hu will meet local officials and visit a high school, Chinese officials said.Chinese President Hu Jintao (R front) meets with Mayor of Chicago Richard Daley(L front) in Chicago, the United States, Jan. 20, 2011. Hu arrived in Washington Tuesday for a four-day visit to the United States. The trip, his second as head of state, is aimed at enhancing the positive, cooperative and comprehensive relationship between China and the United States.The Chinese president visited the United States in April 2006.

BEIJING, Feb. 8 (Xinhua) -- Forty people died in more than 118,000 cases of fire reported across China from February 2 to February 8, as Chinese revelers celebrated the Lunar New Year holiday with fireworks, according to a statement released Tuesday by the country's Ministry of Public Security.The number of cases jumped from the 7,480 fires reported during last year's Spring Festival holiday, which caused losses worth 28.5 million yuan. The incidents also injured 37 people and caused more than 56 million yuan (8.5 million U.S. dollars) in damages, which is almost double the figure from last year.However, this year's losses did not include a case in northeastern Liaoning Province where a five-star hotel in the city of Shenyang was set ablaze by fireworks on February 3.The fire, which caused no casualties, is possibly the country's largest fireworks accident during this year's Spring Festival celebrations.According to the statement, some 260,000 police and fire fighters across the country were mobilized for 24,800 fire control missions.The personnel rescued more than 1,600 people and evacuated tens of thousands. Fire departments have been strengthening monitoring of high-rise buildings, shopping malls, markets, construction sites and other crowded or vulnerable locations.Also, a total of 173 companies were suspended from operating for failing to meet fire prevention and control standards, according to the ministry.

BEIJING, March 10 (Xinhuanet) -- The price of preventing preterm labor is about to rise drastically in the U.S. next week.A drug for high-risk pregnant women costs about 10 to 20 dollars per injection. Next week, the price will shoot up to 1,500 dollars a dose, according to media reports Wednesday.This means the total cost during a pregnancy could be as much as 30,000 dollars.The massive increase comes after KV Pharmaceutical of St. Louis won an exclusive government license to produce the drug, known as Makena.The drug, a form of progesterone given as a weekly shot, has been made cheaply for years by unlicensed chemists.The March of Dimes and many obstetricians supported the move because it means quality will be more consistent and it will be easier to get, but none of them has anticipated the sharp price hike.Doctors and campaign groups have been caught out by the move, saying that the price hike may deter low-income women from getting the drug, leading to more premature births.

NEW YORK, May 27 (Xinhua) -- U.S. stocks expanded gains on Friday ahead of the long Memorial Day weekend as surging commodity prices overcame disappointing economic data.European Central Bank Governing Council member George Provopoulos said that Greece might deal with its debt problem if it sticks to the aid program. That comment, which was considered as bullish by investors, drove the U.S. dollar weaker and led commodity prices surge on Friday.The stock market was driven by higher commodities prices, with thin trading volume ahead of the Memorial Day holiday, despite somewhat disappointing economic data on Friday.The Commerce Department said that both personal income and spending rose 0.4 percent in April, in line with market estimates. However, the rise in spending was the smallest in three months, suggesting the consumption situation was still weak.Meanwhile, pending home sales dropped 11.6 percent in April. The reading was a seven-month low. The market expectation was a drop of 1 percent.Moreover, the Thomson Reuters/University of Michigan Consumer Sentiment index came in above analysts' estimates. Concerns about higher gas prices and inflation had knocked the gauge down in March and April.Despite those disappointing data, analysts still held a bullish view toward the stock market. "Despite our near-term caution, we continue to see the S&P 500 reaching 1400 over the coming year," Alec Young, equity strategist of S&P Equity Research told Xinhua.According to Alex, while recent macro headwinds were raising questions about the sustainability of recent earnings momentum, he still believed that a downside trend of market was fairly limited and that the current weakness is more likely to be a correction, rather than the beginning of a new bear market."In our view, 2011 estimated EPS would have to be excessively optimistic to justify a bear market,"he added.The Dow Jones industrial average added 38.82 points, or 0.31 percent, to 12,441.58. The Standard & Poor's 500 was up 5.41 points, or 0.41 percent, to 1,331.10. The Nasdaq Composite Index rose 13.94 points, or 0.50 percent, to 2,796.86.
