JERUSALEM, July 25 (Xinhua) -- A new study carried out by a Tel Aviv University researcher indicates that the common backache may not only be caused by bad positions or aging, but also by your genes.Prof. Gregory Livshits of the Sackler Faculty of Medicine says that genes play a major role in back pain, especially in the lower back, and in spinal deterioration.In a decade-long project with 2,500 identical and non-identical twins, Livshits found that, in one Arab family, the same back problems appeared in all the members of the family, whether young or old.According to the study, non-identical twins were three times more likely to have back pain, while identical twins were six times more likely to have the same back problems.Livshits believes the discovery of the link between back pains and genes could lead to much better treatment.The research was developed in collaboration with a team of scientists at Kings College, London, led by Prof. Tim Spector and Dr. Fran Williams and was recently published in the journal " Annals of the Rheumatic Diseases."In order to better investigate the genetic causes for one of the world most common pains, Livshits and his colleagues hope to put together an international consortium of research groups.

SAN FRANCISCO, June 22 (Xinhua) -- Apple Inc. plans to introduce a new iPhone in September featuring faster chip and more advanced camera, U.S. media reported on Wednesday.The new iPhone model, which will closely resemble iPhone 4, will include the A5 processor, a more powerful chip that Apple added to the iPad 2 tablet computer earlier this year, along with an 8-megapixel camera, up from the 5-megapixel model in the iPhone 4, Bloomberg quoted two people familiar with the product as saying.The device will run the iOS 5 operating system Apple previewed at its annual developer conference earlier this month.Aiming at attracting customers in developing countries, Apple is also working to finish a cheaper version of the iPhone which will use chips and displays of similar quality to the current iPhone 4, said the sources.Meanwhile, it was reported that Apple is also testing a new version of the iPad with a higher resolution screen, which, similar to the one currently used on iPhone 4, will be about one- third higher than iPad 2 and feature a more responsive touchscreen.According to a recent projection on smartphone market by the International Data Corp. (IDC), a small market share decline of iPhone is expected as the smartphone market matures and diversifies in 2011.The release of a new iPhone would help Apple gain more market share as smartphones powered by Google's Android system are predicted to grow to more than 40 percent of the market in the second half of this year.

BEIJING, June 21 (Xinhua) -- China will launch a new icebreaker for use during an upcoming 2013 polar expedition, a senior oceanic official said on Tuesday.Both the new icebreaker and Xuelong ("Snow Dragon"), an icebreaker that operated in Antarctica, will form an Arctic-Antarctic maritime research team."China will have at least two icebreakers concurrently operating at both the north and south poles," Chen Lianzeng, deputy director of the State Oceanic Administration, told a national conference on polar research, which has been the first since 1984 when the country started expeditions in polar regions.The new icebreaker will boast facilities that will allow it to research the oceanic environment, integrate data for real-time oceanic monitoring, deploy and retrieve detectors and conduct aerial studies using helicopters, Chen said.The two icebreakers will conduct expeditions in polar regions for more than 200 days annually, he said.Fixed-wing aircraft will also be added to the expedition team before 2015, allowing researchers to be transported between China's Zhongshan and Kunlun research stations and Antarctica's Grove Mountains.The Kunlun station went into operation in early 2009 as the first Chinese research station on Antarctica's inland. The Zhongshan station, established in 1989, now serves as a supply base for the Kunlun station.A written comment by Vice Premier Li Keqiang sent to the conference said the polar research, a magnificent feat of the mankind, has great significance for China's oceanic work and sustainable development."Over the past two decades, China's polar research made great achievements and became influential globally," Li said.Li encouraged Chinese scientists to actively participate in international exchanges and cooperation, safeguard national interests and contribute to the peaceful use of polar regions.Since the early 1980s, China has sent 27 Antarctic expedition teams and completed four research missions to the Arctic Ocean.Besides the Xuelong icebreaker, China has built three Antarctic stations -- Changcheng (Great Wall), Zhongshan and Kunlun -- and one Arctic station -- Huanghe (Yellow River) Station.

BEIJING, June 26 (Xinhua) -- A drama honoring an archivist who had devoted himself to the Chinese People's Liberation Army (PLA)'s archive work was staged Saturday evening in Beijing.The drama, "Sheng Ming Dang An," or "Archives of Life," tells the life story of Liu Yiquan who had worked as a file clerk and later a consultant at the PLA Archives for about 38 years.Liu had collected more than 830,000 pieces of military archives, which was regarded as a special contribution to the army. Li Changchun (L, front), a member of the Standing Committee of the Political Bureau of the Communist Party of China (CPC) Central Committee, congratulates actors on the successful performance of drama "life archives" in Beijing, capital of China, June 25, 2011.Despite being diagnosed with terminal cancer in 2008, Liu continued to work hard.
