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.

LOS ANGELES, May 25 (Xinhua) -- NASA project managers bade farewell to the Mars rover Spirit on Wednesday after sending a final set of commands to the stranded vehicle.This marks the completion of one of the most successful missions of interplanetary exploration ever launched, NASA's Jet Propulsion Laboratory (JPL) said."Last night, just after midnight, the last recovery command was sent to Spirit," said John Callas, the Mars Exploration Rover Project manager at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, Los Angeles."It would be an understatement to say this was a significant moment. Since the last communication from Spirit on March 22, 2010, as she entered her fourth Martian winter, nothing has been heard from her."NASA has tried in vain to regain communication with Spirit since it got stuck in sand about two years ago. The rover last communicated on March 22, 2010, as Martian winter approached and the rover's solar-energy supply declined.NASA checked frequently in recent months for possible reawakening of Spirit as solar energy available to the rover increased during Martian spring, but to no avail.A series of additional re-contact attempts ended on Wednesday, designed for various possible combinations of recoverable conditions, according to JPL."Our job was to wear these rovers out exploring, to leave no unutilized capability on the surface of Mars, and for Spirit, we have done that," said Callas.

WASHINGTON, April 13 (Xinhua) -- The U.S. Food and Drug Administration (FDA) announced on Wednesday that it has approved the cPAX Aneurysm Treatment System for surgery on brain aneurysms that are difficult to manage because of their size and shape.An aneurysm is a bulge in the wall of a blood vessel, which can rupture as it increases in size, causing hemorrhage or death. Brain aneurysms often produce no symptoms until they grow and press on nerves in the brain, or until they begin to leak blood or rupture.Aneurysms can be repaired in two ways: surgeons can close the base of the aneurysm with a surgical clip, or use a technique commonly known as coiling, in which surgeons use a catheter to thread metallic coils through a blood vessel in the groin and into the blood vessel in the brain that contains the aneurysm. Surgeons then fill the aneurysm with the detachable coils, which block it from circulation and cause blood to clot, effectively destroying the aneurysm.Aneurysms larger than 10 millimeters are difficult to treat with clipping or coiling. The cPAX device system is indicated for use in those brain aneurysms."Like coiling, the cPAX Aneurysm Treatment System is a form of endovascular repair," said Christy Foreman, director of the Office of Device Evaluation in the FDA's Center for Devices and Radiological Health. "But instead of tiny metallic coils, it uses a special polymer material to fill the space within the aneurysm."According to the FDA, the cPAX device system is indicated for use in adults aged 22 and older and should not be used in patients with an active infection or in those in whom anticoagulation and antiplatelet therapy is contraindicated.

LOS ANGELES, April 8 (Xinhua) -- NASA's Wide-field Infrared Survey Explorer (WISE) has discovered a rare asteroid that traces out a horseshoe shape relative to Earth, the Jet Propulsion Laboratory (JPL) said on Friday.Unlike most near-Earth asteroids (NEAs) that have eccentric, or egg-shaped, orbits that take the asteroids right through the inner solar system, the new object has an orbit that is almost circular such that it cannot come close to any other planet in the solar system except Earth, JPL said.However, even though the asteroid rides around with Earth, it never gets that close, said JPL in Pasadena, Los Angeles.As the asteroid approaches Earth, the planet's gravity causes the object to shift back into a larger orbit that takes longer to go around the sun than Earth. Alternately, as Earth catches up with the asteroid, the planet's gravity causes it to fall into a closer orbit that takes less time to go around the sun than Earth, according to JPL.The asteroid therefore never completely passes our planet. This slingshot-like effect results in a horseshoe-shaped path as seen from Earth, in which the new object, designated 2010 SO16, takes 175 years to get from one end of the horseshoe to the other, JPL said."The origins of this object could prove to be very interesting, " said Amy Mainzer of JPL, the principal investigator of NEOWISE, which is the asteroid- and comet-hunting portion of the WISE survey mission. "We are really excited that the astronomy community is already finding treasures in the NEOWISE data that have been released so far."JPL manages and operates the WISE for NASA's Science Mission Directorate, Washington.

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.
