LOS ANGELES, April 11 (Xinhua) -- Drinking 100-percent fruit juice may offer disease-fighting benefits, a new study suggests.Fruit juice is linked with reduced risk of cancer, improved markers of heart health and cognitive decline, and increased antioxidant activity, according to the study published on Monday by the American Association for the Advancement of Science (AAAS).These protective health benefits are similar to those of whole fruits, said the study, conducted by researchers at the University of California, Davis.The researchers came to the conclusion after summarizing recent research data on the potential benefits of fruit juice. The review included a range of study types, from in vitro to clinical trials (60 papers total), all published in 2005 or later.Among the fruit juices included in the review, consumption of apple, citrus, cranberry, grape, and pomegranate juices all showed beneficial effects. Markers of improved health ranged from reductions in urinary tract infections (cranberry) to improvements in age-related cognitive decline (grape and apple) to reduced risk of prostate (pomegranate) and respiratory and digestive (orange, grapefruit) cancers. Additionally, intake of all juices was linked to heightened antioxidant activity."While it is universally accepted that fruit and vegetable intake is protective, there is not a clear consensus about the benefits of consuming the juices that are extracted from them," said study lead author Dianne Hyson, PhD. "An analysis of the scientific evidence suggests that 100 percent fruit juices retain important bioactive components that may promote good health and aid in disease prevention."

WASHINGTON, March 25 (Xinhua) -- NASA's Stardust spacecraft depleted fuel and ceased operation on Thursday after a 12-year run, the U.S. space agency said Friday."This is the end of the spacecraft's operations, but really just the beginnings of what this spacecraft's accomplishments will give to planetary science," said Lindley Johnson, Stardust-NExT and Discovery program executive at NASA headquarters in Washington."The treasure-trove of science data and engineering information collected and returned by Stardust is invaluable for planning future deep space planetary missions."Artist's concept of Stardust spacecraft nearing EarthLaunched on Feb. 7, 1999, Stardust flew past the asteroid named Annefrank and traveled halfway to Jupiter to collect the particle samples from the comet Wild 2. The spacecraft returned to Earth's vicinity to drop off a sample return capsule eagerly awaited by comet scientists.NASA re-tasked the spacecraft as Stardust-NExT to perform a bonus mission and fly past comet Tempel 1, which was struck by the Deep Impact mission in 2005. The mission collected images and other scientific data to compare with images of that comet collected by the Deep Impact.The Stardust-NExT met all mission goals, and the spacecraft was extremely successful during both missions. From launch until final rocket engine burn, it travelled approximately 3.54 billion miles.After the mileage logged in space, the Stardust team knew the end was near for the spacecraft. With its fuel tank empty and final radio transmission concluded, the most traveled comet hunter will move from NASA's active mission roster to retired."This kind of feels like the end of one of those old western movies where you watch the hero ride his horse toward the distant setting sun -- and then the credits begin to roll," said Stardust-NExT project manager Tim Larson from NASA's Jet Propulsion Laboratory in Pasadena, California. "Only there's no setting sun in space."

BOSTON, the United States, April 9 (Xinhua) -- China's clean energy market offers huge business opportunities, experts said at the Harvard China Forum here Saturday.In a panel discussion on clean energy, experts who have been keeping a close eye on China's renewable sectors evaluated its market size, development level and current challenges."No matter it comes to wind, solar or any other type of clean energy, the market capability in China is enormous," Peter Evans, GE Energy's global strategy and planning director said.Evans said he believed China has the need to develop all kinds of energy in order to meet its ever-growing appetite for energy, especially against the background of high oil price, which just surged to nearly 113 U.S. dollars a barrel.He also said China now has the capital needed to develop clean energy but lacked the technology, although that would not be a problem since "every abroad company related to clean energy wants to go to China and to grab something."Gong Li, chairman of Accenture Greater China, said that for a better development of China's renewable sectors, sustainable policy support is needed.On current challenges, Li said one big problem is the lack of network to turn clean energy into electricity. "Renewable energy such as solar and wind is intermediate energy that needs to be transmitted to the power grid, or else it will be garbage energy," Li said.

SAN FRANCISCO, April 25 (Xinhua) -- Oracle Corp. on Monday announced that its co-president Safra Catz is taking the additional position as the software giant's chief financial officer (CFO), following the resignation of its current CFO Jeff Epstein.Epstein was named Oracle's CFO in September 2008, and had reported directly to Catz. Oracle didn't give details about Epstein's departure.Catz joined Oracle in April 1999 and has been its president since January 2004. She previously served as the company's CFO from November 2005 to September 2008."Safra already has the long-standing confidence of our employees, our Board and our shareholders," Oracle's chief executive officer Larry Ellison said in a statement, adding that " there is no more logical choice for CFO.""The CFO function has reported to Safra for a number of years and she's acted as Oracle's CFO in the past. She has the full support of the Board," noted Jeff Henley, chairman of Oracle's board of directors.

LOS ANGELES, April 12 (Xinhua) -- With the help of NASA Telescopes, astronomers have uncovered one of the youngest galaxies in the distant universe, with stars that formed 13.5 billion years ago, the Jet Propulsion Laboratory (JPL) announced on Tuesday.The finding addresses questions about when the first galaxies arose, and how the early universe evolved, JPL noted in a press release.Infrared data from both the Hubble Space Telescope and the post- coolant, or "warm," phase of NASA's Spitzer Space Telescope mission revealed that the galaxy's stars are quite mature, which means they must have formed when the universe was just a toddler, said JPL in Pasadena, Los Angeles.This challenges theories of how soon galaxies formed in the first years of the universe and could even help solve the mystery of how the hydrogen fog that filled the early universe was cleared, according to astronomers involved in the study.This galaxy is not the most distant ever observed, but it is one of the youngest to be observed with such clarity, JPL said.Normally, galaxies like this one are extremely faint and difficult to study, but, in this case, nature has provided the astronomers with a cosmic magnifying glass, JPL said.The galaxy's image is being magnified by the gravity of a massive cluster of galaxies parked in front of it, making it appear 11 times brighter. This phenomenon is called gravitational lensing."Without this big lens in space, we could not study galaxies this faint with currently available observing facilities," said Eiichi Egami of the University of Arizona in Tucson. "Thanks to nature, we have this great opportunity to see our universe as it was eons ago."The findings may help explain how the early universe became " reionized," according to JPL."Seeing a galaxy as it appeared near the beginning of the universe is an awe-inspiring feat enabled by innovative technology and the fortuitous effect of gravitational lensing," Jon Morse, NASA's Astrophysics Division director at the agency's headquarters in Washington, said in the release."Observations like this open a window across space and time, but more importantly, they inspire future work to one day peer at the stars that lit up the universe following the big bang."
