LOS ANGELES, April 1 (Xinhua) -- A NASA Gulfstream-III aircraft equipped with a synthetic aperture radar is scheduled to depart Sunday, April 3 on a nine-day mission to image Hawaii volcanoes, the Jet Propulsion Laboratory (JPL) announced on Friday.The aircraft will fly from the Dryden Aircraft Operations Facility in Palmdale, California to the Big Island of Hawaii to study the Kilauea volcano that recently erupted, said JPL in Pasadena, Los Angeles.The mission will help scientists better understand processes occurring under Earth's surface, JPL said.Developed by JPL, the Uninhabited Aerial Vehicle Synthetic Aperture Radar, or UAVSAR, uses a technique called interferometric synthetic aperture radar that sends pulses of microwave energy from the aircraft to the ground to detect and measure very subtle deformations in Earth's surface, such as those caused by earthquakes, volcanoes, landslides and glacier movements.As the Gulfstream-III flies at an altitude of about 12,500 meters, the radar, located in a pod under the aircraft's belly, will collect data over Kilauea, according to JPL.The UAVSAR's first data acquisitions over this volcanic region took place in January 2010, when the radar flew over the volcano daily for a week. The UAVSAR detected deflation of Kilauea's caldera over one day, part of a series of deflation-inflation events observed at Kilauea as magma is pumped into the volcano's east rift zone.This month's flights will repeat the 2010 flight paths to an accuracy of within 5 meters, or about 16.5 feet, assisted by a Platform Precision Autopilot designed by engineers at NASA's Dryden Flight Research Center on Edwards Air Force Base, California, JPL said.By comparing these camera-like images, interferograms are formed that reveal changes in Earth's surface, said JPL.Between March 5 and 11, 2011, a spectacular fissure eruption occurred along the east rift zone. Satellite radar imagery captured the progression of this volcanic event."The April 2011 UAVSAR flights will capture the March 2011 fissure eruption surface displacements at high resolution and from multiple viewing directions, giving us an improved resolution of the magma injected into the east rift zone that caused the eruption," said JPL research scientist Paul Lundgren."Our goal is to be able to deploy the UAVSAR on short notice to better understand and aid in responding to hazards from Kilauea and other volcanoes in the Pacific region covered by this study," Lundgren added.

BEIJING, Jan. 26 (Xinhua) -- China remained a major victim of trade protectionism during the past year, witnessing 64 trade disputes in this period, covering some 7 billion U.S. dollars in value, China's Vice Commerce Minister, Zhong Shan, said here Wednesday.The country faced trade disputes with both developed countries and developing ones, which came from not only traditional sectors but also high-tech industries, he told a national conference on trade promotion.For the short- and mid-term, China would work to maintain a stable growth in foreign trade and keep the growth rate higher than both the global level and China's economic growth, he said.China would also strive to achieve a more balanced trade structure by boosting imports and outbound investment, to strengthen the quality and efficiency of foreign trade, he added.China's foreign trade last year jumped 34.7 percent year on year to more than 2.97 trillion U.S. dollars, while its trade surplus fell 6.4 percent to 183.1 billion U.S. dollars.

BEIJING, May 10 (Xinhuanet) -- Researchers from California, Unated States, found that sexual orientation could play a role in cancer and more gay men are reported being cancer survivors than straight men, according to findings in the journal Cancer online Monday.The researchers found that gay men are 1.9 times more likely than straight men to report having had cancer. They also found that lesbian and bisexual women are more than twice as likely as heterosexual women to report fair or poor health after having cancer.Researchers looked at three years of responses to the California Health Interview survey, which included more than 120,000 adults living in the state.Among other health-related questions, participants were asked if they had ever been diagnosed with cancer and whether they identified as gay, lesbian, bisexual, or straight.Out of 51,000 men, about 3,700 said they had been diagnosed with cancer as an adult. While over 8 percent of gay men reported a history of cancer, that figure was only 5 percent in straight men, a disparity that could not be attributed to differences in race, age or income.About 7,300 out of 71,000 women in the study had been diagnosed with cancer, but overall cancer rates did not differ among lesbian, bisexual, and straight women.Ulrike Boehmer, the study's lead author from the Boston University School of Public Health, said higher rates of human immunodeficiency virus (HIV) may be related to the increased risk of cancer in gay men.However, the findings do not necessarily mean that being gay, lesbian or bisexual increases risk of cancer, said the researcher.

STOCKHOLM, Jan. 26 (Xinhua) -- China's railway network, already the world's longest, is developing at record high speed and is to be doubled soon, Swedish daily Svenska Dagbladet reported on Wednesday."China's goal is to connect all important cities with railway lines," the report said.Collaborating with German Siemens, Japanese Kawasaki and Bombardier both in Canada and Sweden, China has built its own high-speed train CRH380A that can reach 486 kilometers per hour, cutting the journey between Beijing and Shanghai in half to about 4 hours.Construction of the high-speed railway network will also cover inland China, the report said. It aims to encourage more investment to move from coastal areas to inland China and ultimately raise the living standards in those regions.Within the next five years, a total of 3.5 trillion yuan (over 500 billion U.S. dollars) will be invested in high-speed track construction and train manufacturing, averaging at about 700 billion yuan (over 100 billion dollars) each year.Swedish companies such as Atlas Copco, SKF and Trelleborg have participated in China's railway and high-speed train development, according to the report.Hans Rosling, a development expert and also professor at Karolinska Institutet in Sweden, was quoted as saying that the construction of the high-speed railway network will bring about "good economy, good education, good medical care, better and longer life, all good things."

SAN FRANCISCO, March 23 (Xinhua) -- Yahoo Inc. on Wednesday introduced a new feature to its search engine, which the company said can deliver answers and direct access to websites before users complete their query or hit the search button.The new feature, called Search Direct, predicts search results as fast as a person types and presents those results dynamically, Yahoo said."With today's launch, direct answers -- not the search results page -- is the primary focus. We are redefining the search process and prominently displaying direct answers where search decisions are being made," Shashi Seth, Yahoo's senior vice president of search and marketplaces, said in a statement."Search Direct is evidence of Yahoo continuing to lead innovation in search, enabling people to take action faster, find what is most important, and sample what is possible with the next stage of search technology," he added.Yahoo announced that Search Direct is rolling out in a public test version to its users across the United States Wednesday, and will be available in other Yahoo products and markets later this year.
