NEW DELHI, March 5 (Xinhua) -- Doctors in India have claimed to have successfully performed a rare robotic heart surgery on a 23- year-old person at a hospital in the southern Indian city of Chennai, local media reported Saturday.Dr. R. Ravi Kumar, the Director of the Institute of Cardiovascular Disease at the Chettinad Health City, said the robotically assisted procedure involved replacing both the mitral and the aortal valve simultaneously.The surgery carried out on D. Vijayakanth, an auto driver from Vellore, was done by a three armed robot, took four hours and cost 225,000 rupees (4,500 U.S. dollars)."The best part about using a robot in cardiac surgery is that the patient's heart need not be opened and the surgery can be done using a small 4cm incision. This is not possible with normal surgeries without a robot," Dr Ravi Kumar was quoted by local daily The Times of India as saying.Robotic surgery, which is fairly new in the country, can be used for a gamut of medical procedures, said Dr Ravi Kumar."It requires a lot of precision and intense training because though the robotic hands do the surgery, it has to be controlled by a trained surgeon. One of the biggest disadvantages is the lack of sensory perception which is there when the surgeon actually does the surgery himself," he said.

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."

BEIJING, Feb. 21 (Xinhua) -- China's top leading body Monday pledged to prevent wild swings in the economy, while warning that the economic situation in 2011 would be complicated.The country should maintain stable and consistent macro-economic policies while improving accuracy, flexibility and efficiency of the policies, the Political Bureau of the Communist Party of China (CPC) Central Committee decided at a meeting presided over by President Hu Jintao, who is also General Secretary of the CPC Central Committee.Officials at the meeting were urged to "remain sober, be aware of difficulties, and work hard to fulfill the tasks this year so as to create a good beginning for the 12th Five-Year Program (2011-2015)."The top echelon of leadership reassured that China would continue an active fiscal policy and prudent monetary policy, while trying to balance steady economic growth with economic restructuring and control of inflationary expectations."It is necessary to maintain stable commodity prices, expand domestic consumption, increase investment in agriculture, speed up industrial restructuring, promote education and development of science and technology, and improve people's livelihoods and cultural services," the Political Bureau of the CPC Central Committee urged at the meeting.It also reiterated the importance of making great efforts to expand reforms in key sectors, advance the cause of opening-up, while intensifying endeavor to build a clean government and fight corruption.Members of the Political Bureau of the CPC Central Committee also discussed the drafts of the government work report and the 12th Five-year Program, or the national development plan for 2011 to 2015.The two documents will be submitted to the top legislature for discussion and approval at its forthcoming annual session in March.The period from 2011 to 2015 will be critical for China which wants to build a well-off society, said a statement from the meeting.In the next five years, in a bid to meet Chinese people's expectations for a better life, China will stick to scientific development by focusing on accelerated transformation of its way of economic growth while deepening the reform and opening-up, guaranteeing and improving people's livelihoods, according to the statement."It is necessary to solidify and boost China's success in outperforming other countries in dealing with the international financial turmoil, and advance the economy to grow at a faster and steady pace for a long time while guaranteeing social harmony and stability," the statement said.Great efforts should also be made to develop social services, advance the cause of conserving energy and resources, protecting the environment in a down-to-earth manner, as well as keep intensifying the drive to enhance reform of the government, the statement said.

BEIJING, Feb. 23 (Xinhua) -- A senior official of the ruling Forces pour la Defense de la Democratie (FDD) of Burundi said Tuesday the FDD hopes to strengthen cooperation with the Communist Party of China (CPC) and to further enhance the "brotherly friendship" with the CPC.Mohamed Rukara, vice president of the Council of Elders, the top decision-making body of the FDD, said in an interview with Xinhua that there are a lot of ruling experiences of CPC that the FDD can learn from.He said the CPC has gained great achievements in China's reform and opening up, realizing sustainable development, developing science and technology and striking corruption.He said Burundi has set "sustainable development" as the slogan for the 2010-2015 period, and he believed that his country can learn from China's successful experiences of reform and opening up and realize the goal of shaking off poverty by 2020-2025.Rukara, who is also a ombudsman, said corruption has been a big challenge facing his country, and he believed the FDD can learn from the CPC in this regard, as the latter has been combating corruption very hard and effectively.Appreciating China's aid and contribution to the development of Burundi, Rukara said the two parties and the two countries have had very good relations based on mutual respect.He welcomed more Chinese enterprises to invest in Burundi to support its development, and "the door will always be open to our brother."At the invitation of the CPC, Rukara is heading an FDD delegation for a visit to China starting from Saturday.

Google chairman Eric Schmidt has promised that the firm will simplify the process by which Android phone users agree to share their data.It follows questions in the US Senate about how much location information is stored by mobile handsets.Speaking in the UK at a conference on privacy, he also revealed that Google plans to offer web users more control over their online profile.Mr Schmidt insisted that the company took the matter "very seriously".He told attendees at the Big Tent debate in Hertfordshire that his firm was working on "a series of projects" aimed at increasing transparency.Those include a revised Google Dashboard, where users can see what data they have shared with the search giant."It is worth stressing that we can only do this with data you have shared with Google. We can't be a vacuum-cleaner for the whole internet," he said.Mr Schmidt stressed that Google was on the side of consumers when it came to privacy. "In general we take the position that you own your data and should be able to opt in or out of a service," he said.But he added that if users gave consent for sharing data, it would help Google improve its services."If you choose to give us that information we can do a better job. If we know a little bit more about you we can offer better targeted search," he explained.Super injunctions revealed A recent hearing in the US Senate quizzed Google on the amount of data stored on Android handsets. The company argued that it allows people to opt out of location-based services.But Mr Schmidt conceded that the terms and conditions whereby users sign up to services needs to be simplified. "We intent to do that," he said.He predicted that such services would be more heavily regulated in the future.During a lively debate on the issue of privacy, it was revealed to the Big Tent audience, alongside several names of current super-injunction holders, that more data has been collected in the last seven years than in the whole of previous human history.
