BEIJING, April 14 (Xinhuanet) -- The discovery of a sharp-toothed dinosaur fossil in New Mexico, the United States, may bridge a gap in the evolution of the species, researchers said in Wednesday's journal Proceedings of the Royal Society B.Researchers from the Smithsonian Institution unearthed the dinosaur skull and neck vertebrae in Abiquiu, New Mexico, where it had remained buried for around 230 million years. The short snout and slanting front teeth of the find — Daemonosaurus chauliodus — had never before been seen in a Triassic era dinosaur, said Hans-Dieter Sues of the Smithsonian's National Museum of Natural History.Sues, curator of vertebrate paleontology at the museum, said the discovery helps fill the evolutionary gap between the dinosaurs that lived in what is now Argentina and Brazil about 230 million years ago and the later theropods like the famous Tyrannosaurus rex."Various features of the skull and neck in Daemonosaurus indicate that it was intermediate between the earliest known predatory dinosaurs from South America and more advanced theropod dinosaurs," said Sues."One such feature is the presence of cavities on some of the neck vertebrae related to the structure of the respiratory system," he added.The discovery suggests that there is still much to be learned about the early evolution of dinosaurs."The continued exploration of even well-studied regions like the American Southwest will still yield remarkable new fossil finds," Sues said.

SAN FRANCISCO, April 7 (Xinhua) -- A latest research has shown that worldwide camera phone sales, driven by fast growing high- tier camera phone market, will top 1 billion units for the first time in 2011.According to the study by Strategy Analytics, a global independent research and consulting firm, sales of camera phones are projected to grow by 21 percent from 918 million units last year to 1.114 billion units in 2011, which will be the first time that annual volumes of camera phones have exceeded the 1-billion mark."The fastest growing segment of the camera phone market will be the high-tier. We forecast camera phones with sensors of eight megapixels and above to grow a healthy 240 percent worldwide during 2011," Neil Mawston, director at Strategy Analytics, said in a statement on Thursday.He added that smartphone vendors, such as Nokia and HTC, are increasingly loading their flagship models with more megapixels to deliver improved imaging quality for premium operator services.Statistics from Strategy Analytics show that some 4.2 billion camera phones have been sold worldwide since 2000.

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, May 16 (Xinhuanet) -- NASA has readied the space shuttle Endeavour for its liftoff set for Monday, media reported Monday.Good weather looks 70 percent likely for Monday's scheduled launch of Endeavour, the next-to-last U.S. space shuttle mission as NASA develops a new generation of craft for longer voyages."The updated forecast Sunday for Monday's launch of the shuttle Endeavour remains unchanged with a 70 percent chance of good weather," said NASA spokesman Allard Beutel.The space shuttle Endeavour STS-134 sits on launch pad 39A after the rollback of the Rotating Service Structure at the Kennedy Space Center in Cape Canaveral, Florida May 15, 2011.Liftoff is set for 8:56 a.m. EDT (1256 GMT) from the Kennedy Space Center for the trip to the International Space Station after the U.S. space agency repaired a technical glitch that canceled last month's launch attempt.The initial April 29 launch attempt was scrubbed hours before liftoff when technicians discovered a power failure in a heating line that served to prevent fuel from freezing in orbit.The six-member crew of astronauts including five Americans and one Italian, Roberto Vittori, will deliver a potent physics experiment to probe the origins of the universe during the mission, which will include four spacewalks.The 16-day mission is intended to help get the space station ready for operations after the shuttle fleet is retired. The 135th and final shuttle launch is scheduled for early- to mid-July aboard Atlantis.

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.
