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."

CAIRO, Jan. 23 (Xinhua) -- The first training session for Egyptian Chinese language teachers to improve their teaching ability started on Sunday in Cairo.The session, under the supervision of the Chinese Confucius institute, will concentrate on the exchange of experiences in teaching the Chinese language in Egypt and the enhancement of Egyptian teachers' ability to make better use of the textbooks.The three-day training session will contain language and cultural courses by professors and instructors from famous Chinese universities such as Beijing University and Beijing Foreign Studies University, said Li Shengjun, head of the Confucius Institute at Cairo University.Nearly 60 Egyptian Chinese language teachers, including 14 professors, from universities including Cairo University, Ain Shams University and Minya University will attend the training courses.China has established 691 Confucius institutes and classes in around 69 countries until 2010, including nine in the Arab countries.

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.

BEIJING, Feb. 15 (Xinhua) -- A senior Chinese mainland official has said the government will work with Taiwan to enhance cross-Strait economic exchanges and cooperation.The mainland would this year focus on fulfilling the cross-Strait Economic Cooperation Framework Agreement (ECFA) and conducting follow-up negotiations on the pact, which took effect in September last year, Xu Mang, director of the economy bureau of the Taiwan Affairs Office of the State Council, told Xinhua in an interview.Top of the follow-up agenda was cross-Strait investment protection. The mainland hoped to reach a mutually beneficial agreement on the issue with Taiwan at an early date, with concerns of both sides respected, Xu said.Xu said the two sides should adhere to the principle of balance in negotiations, aiming for effective protection, fewer restrictions and more convenience for cross-Strait investment.Mainland and Taiwan negotiators agreed in December last year to continue discussing the investment protection agreement at the seventh round of talks scheduled for this year.The mainland would also continue this year to encourage investment in Taiwan, address Taiwan enterprises' concerns over economic transformation and development, and promote cross-Strait cooperation in finance, modern services and agriculture, Xu said.The first step in implementing the ECFA, the "early harvest program," took effect on Jan. 1, when the mainland reduced tariffs on 539 Taiwanese items, or 16 percent of imports from Taiwan, while Taiwan cut duties on 267 mainland items, 10 percent of imports from the mainland.Within two years, the duties on those products will be reduced to zero.Xu said the implementation of the early harvest program would boost trade links across the Strait.As the products receiving tariff reductions covered industries including agriculture, petrochemicals, machinery, textiles and transport, Taiwan businesses on the mainland would benefit from lower purchase costs on Taiwan raw materials, Xu said.Taiwan's small and medium-sized enterprises and low-income groups would especially benefit from the tariff reductions on exports of 18 agricultural products to the mainland, Xu said.Statistics from Taiwan showed that driven by the tariff reduction, the island's small and medium-sized enterprise export trade volume to the mainland would increase to 18 billion U.S. dollars per year."The tariff reduction policy will benefit more Taiwan compatriots," Xu said.Cross-Strait trade volume totaled 145.37 billion U.S. dollars last year, a rise of 36.9 percent year on year. The figure included 115.69 billion U.S. dollars of Taiwan exports to the mainland, up 20.2 percent. 

LOS ANGELES, April 2 (Xinhua) -- The United States could soon be faced with an epidemic of Non-Alcoholic Fatty Liver Disease ( NAFLD), one of the major contributing factors of chronic liver disease (CLD), the American Association for the Advancement of Science (AAAS) reported Saturday.If the current rates of obesity and diabetes continue for another two decades, the prevalence of NAFLD in the U.S. is expected to increase by 50 percent in 2030, AAAS said.The prediction is based on pre-existing clinical survey data over a 10 year period (1988-1994, 1999-2004 and 2005-2008), which included 39,500 adults from three survey cycles, according to the AAAS.Over the three cycles, the prevalence of NAFLD doubled from 5. 51 percent to 11 percent respectively. Furthermore, during the first survey cycle (1988-1994) 46.8 percent of all CLD's was related to NAFLD but by 2005-2008 this had increased to 75.1 percent. In addition, the prevalence of obesity and diabetes, the two key risk factors for NAFLD also steadily increased."If the obesity epidemic is anything to go by, the U.S. NAFLD epidemic may have a ripple effect worldwide," said Mark Thursz, Vice Secretary of the European Association for the Study of the Liver. "It is imperative that health systems continue to drive effective educational programs to reinforce awareness among the general public to alert them of the risks of obesity and promote the importance of diet and exercise."Non-alcoholic fatty liver disease is fast becoming one of the top concerns for clinicians due to the obesity epidemic and it's potential to progress to advanced liver disease which significantly impacts on overall liver-related mortality, Thursz said in remarks published by AAAS' website EurekAlert.org.NAFLD, considered as one of the major causes of morbidity and mortality worldwide, is the term used to describe fat build-up in liver cells in people who do not drink alcohol excessively. The disease is the most common persistent liver disorder in Western countries with an estimated overall prevalence of 20-30 percent, according to AAAS.NAFLD encompasses a spectrum of liver disease associated with insulin resistance, diabetes and obesity and as such people most at risk of NAFLD are those who are obese, have insulin resistance associated with diabetes, high blood pressure and cholesterol.
