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.

LOS ANGELES, April 7 (Xinhua) -- A new research has found that about nine million people in the United States identify themselves as lesbian, gay, bisexual or transgender (LGBT).About 1.8 percent of adults identify themselves as bisexual, 1. 7 percent as gay or lesbian, and 0.03 percent as transgender, researchers at the University of California-Los Angeles' School of Law said in the study published by The Los Angeles Times on Thursday.The study culled data and methods from nine surveys conducted over the last seven years and averaged results from five of those surveys to estimate sexual orientation and from two surveys to estimate the transgender population.The findings also show that about 8.2 percent of Americans said they participated in same-sex sexual activity and about 11 percent said they had some same-sex sexual attraction, but neither of these groups necessarily identified themselves as LGBT.The researchers noted that insufficient and inconsistent national surveys make it difficult to get an estimate of the LGBT population in the United States, according to the Times report.

CANBERRA, March 23 (Xinhua) -- Up to 45 native species in Western Australia's Kimberley region will die out within 20 years if no action is taken, latest study showed on Wednesday.The Priority Threat Management to Protect Kimberley Wildlife report, released by Commonwealth Scientific and Industrial Research Organization (CSIRO) on Wednesday, was commissioned by the Wilderness Society.The report showed that at present, 20.2 million U.S. dollars a year is spent on conservation efforts in the Kimberley, which is home to an assortment of threatened species.However, the report said even if that money was spent properly, the region would still lose some 31 native animals.The numbers of many more birds, reptiles and mammals, such as the Spotted Tree Monitor and the Western Chestnut Mouse, would dwindle.It called for an immediate cash injection of 96 million U.S. dollars to save creatures like the Golden Bandicoot, the Scaly- Tailed Possum and the Monjon Rock Wallaby from extinction.It will follow by an ongoing investment of 40.43 million U.S. dollars annually in the Kimberley to protect its species, as well as boost plant life, help the climate and conserve indigenous land."This investment is great value," one of the report's six co- authors Hugh Possingham said in a statement released on Wednesday."We can save some of Australia's most iconic mammals and birds at a cost of only about one million U.S. dollars per species per year."

BEIJING, Jan. 31 (Xinhua) -- The Ministry of Culture, along with seven other central departments, announced on Monday the launching of the "parental watch project" in the online games industry beginning March 1.The project will require online game companies to set up a web page, enquiry hotline and other special channels for parental supervision of their children.Besides, these companies shall authorize parents, who want to monitor and control their children playing online games, to take measures to limit or ban the playing.Also, the online game companies shall provide help to parents in supervising their children's online game accounts and preventing them from playing improper games, as part of the project.The culture ministry tested the project in several online game companies in Feb last year, which proved effective in helping juveniles overcome addictions to online games.

SAN FRANCISCO, May 10 (Xinhua) -- Google on Tuesday launched its long-awaited cloud-based music service Music Beta without any label licenses it originally wanted.The search giant introduced the digital music locker service at its annual I/O developer conference in San Francisco. So far, only U.S. users can access the service by requesting an invitation from Google while priorities will be given to those with the Verizon version of the Motorola Xoom tablet and attendees of the I/O conference.Since Google failed to come to a license agreement with major music labels, Music Beta is essentially a massive cloud hard drive. Users cannot share their Music Beta by Google tunes or purchase new songs. It allows users to upload 20,000 songs into the cloud, compared with Amazon Cloud Drive's 2,000 songs and 5 GB limit for free accounts.Any web-connected devices with a browser or supporting Flash can stream music from the digital locker, but the service is only for Android-powered devices.Music Beta also gets Instant Mix, a similar intelligent feature to Apple's Genius playlist creator, which creates new playlists based on a single song by analyzing its characteristics.Before unveiling the service, Google told U.S. media Monday night that the current Music Beta is not the service Google had wanted to offer and it will continue to seek licenses with major music labels.
