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."

XI'AN, Feb. 21 (Xinhua) -- Nearly 100 children were sickened by food poisoning Monday noon at a kindergarten in northwest China's Shaanxi Province.The accident occurred at Zhaocun Beibeile Kindergarten at Weiyang District of the provincial capital Xi'an City, where the children suffered from nausea and diarrhea after lunch, said a spokesman from the Weiyang District Government.The sickened children were rushed to five local hospitals for treatment, and their conditions were reported as not life threatening, the spokesman said.An initial inspection showed that their sickness was caused by nitrite intoxication, and the exact cause is under investigation.

BEIJING, Jan. 21 (Xinhua) -- Chinese Vice Premier Li Keqiang on Friday stressed the importance that local governments improve management of land and resources, as it remains vital for the stable and relatively quick development of the nation's economy.Li said China faced the difficult tasks of land and resource management as resources are becoming scarce amid the country's quickening industrialization, urbanization, and agricultural modernization.He said the nation must continue preserving arable land. To ensure grain security, China set a "red line" to guarantee its arable land never shrinks to less than 1.8 billion mu (120 million hectares).Chinese Vice Premier Li Keqiang (R) shakes hands with outstanding representatives from local departments in charge of land and resources in Beijing, capital of China, Jan. 21, 2011.Li also called on local authorities to step up efforts to protect valuable mineral resources while using resources more efficiently and in a frugal manner.At the same time, the senior Chinese official said land should be guaranteed for the nation's plan to build 10 million affordable houses for low and middle income people this year.Further, Li urged local authorities to improve work in monitoring and taking precautionary measures against geological disasters to ensure the safety of people's lives and property.

VIENNA, March 18 (Xinhua) -- The 26th Annual Congress of the European Association of Urology (2011 EAU congress) kicked off on Friday at the Vienna Austria Center in the Austrian capital Vienna.About 14,000 doctors, experts, scholars and representatives of pharmaceutical enterprises in the field of urology from more than 80 countries took part in the event, which will last till Tuesday.The EAU congress is Europe's largest fair in the field of urology. This is the third time for Vienna to host the event.The EAU congress aims to review technical innovation and technological progress in the field of urology and related subspecialties, discuss new theories, new technologies and new diagnostic methods of urological clinical trials, optimize the risk management of urological disease, and enhance doctors' practical knowledge and skills by educational activities.It also provides an important platform for related pharmaceutical, medical equipments and medical consumables manufacturers to present their latest products and technologies, and creates the opportunity of face-to-face communication between suppliers and consumers.The highlights of this year's EAU congress include the discussion of state-of-the-art kidney imaging and the application of ultrasound, computerized tomography (CT-scan) and magnetic resonance imaging (MRI).Participants are also expected to give a timely overview on the role of imaging, focal therapy and kidney biopsy in the management and follow-up of small renal masses, as well as the use of imaging in the management of urinary incontinence and other pelvic urinary pathologies.Congress organizers said that more than 200 presentations and seminars are scheduled during the five-day meeting, with an estimated 400 speakers unveiling their latest findings.

CANBERRA, April 1 (Xinhua) -- People who share bongs to smoke marijuana may be at risk of contracting pulmonary tuberculosis (TB) , Australian medical researchers warned on Friday.Dr Michael Hayes and Dr Susan Miles from Calvary Mater Hospital in Newcastle of Australia conducted the research, which centered on three recent TB cases in New South Wales.TB is caused by the bacteria Mycobacterium tuberculosis, which can be contracted by breathing in air droplets coughed from an infected person.The research suggested a link between active TB cases and shared bongs, which is the water pipes commonly used in marijuana smoking.According to Dr Hayes, the three young patients were regular or heavy cannabis users, and more recently there has been a fourth person in the region with similar characteristics had been diagnosed with TB.He said although the three initial cases were not related, there was concern about the high rate of positive contacts among people who had shared bongs with the active cases."Smoking marijuana is a cough-provoking activity and it is usually conducted in a confined environment that is conducive to the spread of the organism," he told Australia Associated Press.
