JERUSALEM, May 8 (Xinhua) -- Israeli researcher Jacob (Koby) Scheuer, from the Tel Aviv University (TAU) School of Electrical Engineering, has developed a nano-scale gyroscope, the Ha'aretz daily reported Sunday.Scheuer developed a new optic-fiber nano-sensor four years ago, along with an optic gyroscope that works in conjunction with the sensor. As he developed the devices, it occurred to him that his discovery could be harnessed to surgical needs, virtual reality, or communications, said the report."What we developed here is an optic gyroscope," Scheuer told Xinhua in a recent interview on Sunday, "like the others, but the breakthrough is that we found a way to measure rotation in a very, very small device using the optic sensor."Optic gyroscopes emit light when they rotate, and change its wavelength when there is any change in the speed of rotation, making it possible to measure velocity and position by the differences in light.Scheuer's gyroscope, however, is so small in comparison to the others commonly used in planes, trains and vehicles, that it can be used in cell phones or watches and does not need satellite connection like the ubiquitous Global Positioning System.The applications of this gyroscope and optic sensor are almost endless, as Scheuer puts it."It can be a pill that you swallow and can move through your body to take pictures or release drugs in a localized area," the researcher explained, "or it can be used by a doctor to operate on a patient who is thousands of kilometers away.""Our gyroscope has complete independent navigation capability, which the others don't have," he stressed.Though the new optic gyroscope works in theory, it still hasn't been tried in out in reality. "It will take some time until we can empirically demonstrate our work, I would say about three to five years," Scheuer added.Alongside the gyroscope, Scheuer continues to work on the optic sensor, whose applications can also be found in security, such as an information security system developed by Scheuer to safeguard online information that acts as a key bearer."When both parties have 'the key' it's virtually impossible to hack the information sent," Scheuer noted, terming the development as a "total paradigm change."

WASHINGTON, May 11 (Xinhua) -- NASA's Dawn spacecraft has obtained its first image of the giant asteroid Vesta, which will help fine-tune navigation during its approach, the U.S. space agency announced Wednesday.Dawn expects to achieve orbit around Vesta on July 16, when the asteroid is about 117 million miles from Earth.The image from Dawn's framing cameras was taken on May 3 when the spacecraft began its approach and was approximately 752,000 miles (1.21 million km) from Vesta. The asteroid appears as a small, bright pearl against a background of stars. Vesta also is known as a protoplanet, because it is a large body that almost formed into a planet."After plying the seas of space for more than a billion miles, the Dawn team finally spotted its target," said Carol Raymond, Dawn's deputy principal investigator at NASA's Jet Propulsion Laboratory in Pasadena, California. "This first image hints of detailed portraits to come from Dawn's upcoming visit."Vesta is 330 miles (530 km) in diameter and the second most massive object in the asteroid belt. Ground- and space-based telescopes obtained images of the bright orb for about two centuries, but with little surface detail.Mission managers expect Vesta's gravity to capture Dawn in orbit on July 16. To enter orbit, Dawn must match the asteroid's path around the sun, which requires very precise knowledge of the body's location and speed. By analyzing where Vesta appears relative to stars in framing camera images, navigators will pin down its location and enable engineers to refine the spacecraft's trajectory.Dawn will start collecting science data in early August at an altitude of approximately 1,700 miles (2,700 km) above the asteroid's surface. As the spacecraft gets closer, it will snap multi-angle images allowing scientists to produce topographic maps. Dawn will later orbit at approximately 120 miles (200 km) to perform other measurements and obtain closer shots of parts of the surface. Dawn will remain in orbit around Vesta for one year. After another long cruise phase, Dawn will arrive in 2015 at its second destination, Ceres, an even more massive body in the asteroid belt.Gathering information about these two icons of the asteroid belt will help scientists unlock the secrets of our solar system's early history. The mission will compare and contrast the two giant asteroids shaped by different forces. Dawn's science instruments will measure surface composition, topography and texture. Dawn also will measure the tug of gravity from Vesta and Ceres to learn more about their internal structures. The spacecraft's full odyssey will take it on a 3-billion-mile (5-billion-km) journey, which began with its launch in September 2007.

PARIS, April 22 (Xinhua) -- Heavy load launcher Ariane 5 lifted off two communication satellites, Yahsat Y1A and Intelsat New Dawn, at around 6:37 p.m. local time (2137 GMT) on Friday from Europe's Spaceport in French Guiana.Yahsat Y1A is the first United Arab Emirates satellite launched by Arianespace. It is built by Astrium and Thales Alenia Space and will be positioned at 52.5 degrees East. With a design life of 15 years, it will be operated by the Al Yah Satellite Communications Company, a telecommunications company indirectly controlled by the Abu Dhabi Government.Weighing around 5,935 kilograms at lift-off, Yahsat Y1A was expected to be separated first around 27 minutes after the launcher started the flight.The second passenger Intelsat New Dawn was built by Orbital Sciences Corporation and weighs about 3,000 kilograms. Also with a designed life span of 15 years, it is planned to be positioned at 32.8 degrees East.Via the second mission of Ariane 5 in 2011, Yahsat Y1A will provide customized relay services for the government and commercial sectors in the Middle East, Africa, Europe and Southwest Asia, while Intelsat New Dawn will work as a part of the global Intelsat fleet, offering service for Africa.This launch, the 201st of an Ariane family vehicle since 1979, brought to 22 the number of Intelsat satellites serving Africa, according to the launching company.Originally scheduled for liftoff on March 30, this dual-payload mission was delayed following an interruption of the final countdown when an incorrect displacement of one of the engine's actuators was detected, Arianespace said in a statement. The launching center planned to have six liftoffs of Ariane 5 through this year.

BEIJING, Feb. 17 (Xinhua) -- China's new rules for reviewing proposed mergers and acquisition (M&A) deals by foreign firms on grounds of national security would benefit both Chinese and foreign investors, a Ministry of Commerce (MOC) spokesman said Thursday.The rules will facilitate the growth of foreign-invested enterprises (FIEs) in China and improve the quality and structure of foreign direct investment (FDI) flowing into China, MOC spokesman Yao Jian said at a press conference.The move also marked an improving legal environment for the security of China's business sector along with its opening-up drive, given that M&A by FIEs will increasingly become a trend in the coming years, Yao said."The adoption of the rules in China will also increase policy transparency and improve law-based government administration," said Yao.Yao's words came after the State Council, China's Cabinet, announced last Saturday that it was establishing a panel to check whether M&A deals struck by foreign firms in the country endanger national security.The panel will review attempts by FIEs to buy or merge with domestic companies whose business pertains to national defence, agriculture, energy, resources, key infrastructure, transport systems, key technology sectors and important equipment manufacturing industries, according to a statement published on the central government's website www.gov.cn.The review will be conducted by a foreign investment security review board under the cabinet, members of which come from the National Development and Reform Commission (NDRC), the MOC and other agencies.The new regulations, which take effect in March, come at a time when China is expected to see more M&A deals struck by foreign firms.Currently, inward M&A accounts for about 3 percent of China's total FDI, a sharp contrast with the global average level of more than 70 percent, said Yao. "M&A by FIEs will become a major trend in China."China's taking in FDI through more M&A will promote industrial consolidation and restructuring, and it will also mean more efficient utilization of the existing resources, he said."As the share of M&A in the FDI will probably rise from the current 3 percent to 8 percent, 10 percent or even more, it is necessary to timely formulate China's own rules governing foreign takeovers in line with international standards," Yao said.In April 2010, the State Council said in a statement that foreign investment should be allowed to be more diversified and foreign investors encouraged to participate in the consolidation and restructuring of domestic firms via equity holdings or acquisitions.He Manqing, a researcher with the Chinese Academy of International Trade and Economic Cooperation of the MOC, said "It is right and proper to impose regulations and requirements on proposed M&A deals in the sectors of strategic importance and those involving national security.""The introduction of the regulations conforms to the new trend in China's receiving of FDI and indicates that China's regulations on FDI are becoming more mature," said He.The NDRC said Wednesday that national security scrutiny would only occur when foreign companies take a majority stake in a domestic M&A deal, meaning that a minority stake purchase will not trigger a review."The new rules draw references from similar rules in the United States, Germany and Canada," the NDRC said in a statement on its website.The NDRC also said that the new regulations were in line with World Trade Organization rules and did not imply that China had changed its policies on opening up and attracting FDI.China's FDI jumped 23.4 percent in January to 10.03 billion U.S. dollars, said Yao. The monthly growth rate was up from December's 15.6 percent.As the world's top investment destination, China received a total of 105.74 billion U.S dollars in FDI in 2010, up 17.4 percent year on year, the MOC said last month.

BEIJING, Feb. 27 (Xinhua) -- A total of 2.64 billion trips in China were recorded by road or ships during the 40-day Spring Festival transportation season which ended Sunday, the Ministry of Transport said.The figure was 13.6 percent higher than the same period last year, noted ministry spokesman He Jianzhong.To ensure smooth transportation, 840,000 buses were put into use each day during the busy season, as well as 13,089 ships, He said.Statistics on railway transportation are not yet available.However, statistics from the Beijing railway administration showed 20.63 million tourists had left Beijing during the transportation season from Jan. 19 to Feb. 27, up 3.9 percent year on year.The busy Spring Festival transportation season runs for 40 days and is calculated in two phases: 15 days before and 25 days after the Spring Festival.
