SAN FRANCISCO, April 7 (Xinhua) -- A latest research has shown that worldwide camera phone sales, driven by fast growing high- tier camera phone market, will top 1 billion units for the first time in 2011.According to the study by Strategy Analytics, a global independent research and consulting firm, sales of camera phones are projected to grow by 21 percent from 918 million units last year to 1.114 billion units in 2011, which will be the first time that annual volumes of camera phones have exceeded the 1-billion mark."The fastest growing segment of the camera phone market will be the high-tier. We forecast camera phones with sensors of eight megapixels and above to grow a healthy 240 percent worldwide during 2011," Neil Mawston, director at Strategy Analytics, said in a statement on Thursday.He added that smartphone vendors, such as Nokia and HTC, are increasingly loading their flagship models with more megapixels to deliver improved imaging quality for premium operator services.Statistics from Strategy Analytics show that some 4.2 billion camera phones have been sold worldwide since 2000.

LOS ANGELES, April 14 (Xinhua) -- Vegetarians experience a much lower risk of metabolic syndrome than non-vegetarians, U.S. researchers have found.Researchers at Loma Linda University in California based their findings on analysis of more than 700 adults randomly sampled from a long-term study of the lifestyle and health of almost 100,000 Seventh-day Adventist Christians across the United States and Canada.While 25 percent of vegetarians had metabolic syndrome, the number significantly rises to 37 percent for semi-vegetarians and 39 percent for non-vegetarians, according to the study published in the April issue of the journal Diabetes Care.The findings showed that the risk of developing metabolic syndrome is 36 percent lower among vegetarians than non- vegetarians.This means that vegetarians are less likely to develop heart disease, diabetes and stroke -- three major conditions that are closely linked with metabolic syndrome, the researchers say.The study also found that vegetarians, though slightly older than non-vegetarians, had lower triglycerides, glucose levels, blood pressure, waist circumference, and body mass index (BMI). Semi-vegetarians, meanwhile, also had a significantly lower BMI and waist circumference compared to those who ate meat more regularly.The findings will not be affected by other factors such as age, gender, race, physical activity, calories consumed, smoking, and alcohol intake, the researchers say."In view of the high rate of metabolic syndrome in the United States and its deleterious health effects, we wanted to examine lifestyle patterns that could be effective in the prevention and possible treatment of this disorder," says lead researcher Nico S. Rizzo, PhD."I was not sure if there would be a significant difference between vegetarians and non-vegetarians, and I was surprised by just how much the numbers contrast," he says. "It indicates that lifestyle factors such as diet can be important in the prevention of metabolic syndrome."

WASHINGTON, April 6 (Xinhua) -- U.S. researchers have discovered two genes in which variation affects intake of caffeine, the most widely consumed stimulant in the world, according to a report described Wednesday in the open-access journal PLoS Genetics.A team of investigators from the National Cancer Institute, Harvard School of Public Health, Brigham and Women's Hospital, and the University of North Carolina at Chapel Hill examined genetic variation across the entire genome of more than 47,000 individuals from the U.S.They found the genes -- CYP1A2, which has previously been implicated in the metabolism of caffeine, and AHR, involved in the regulation of CYP1A2, played roles in regulating intake of caffeine. Individuals with the highest-consumption genotype for either gene consumed 40 mg more caffeine than those with the lowest-consumption genotype, equivalent to the amount of one-third cup of caffeinated coffee, or one can of cola.Caffeine is implicated in numerous physiological and medical conditions; it affects sleep patterns, energy levels, mood, and mental and physical performance. The identification of genes that have an impact on daily consumption offers opportunities to better understand these conditions. Further exploration of the identified genetic variants may provide insight into the speed of caffeine metabolism, how long caffeine circulates in the blood, or how strong the physiological effects of consuming a given amount of caffeine are.

TOKYO, Feb. 6 (Xinhua) -- Japanese Prime Minister Naoto Kan said Sunday that Japan is ready to reconstruct relations with China in cultural, economic, political and other areas, the Jiji Press reported."This year marks the 100th anniversary of China's Revolution of 1911, and next year will be the 40th anniversary of the normalization of Sino-Japanese relations," said Kan at the first session of the "China-issue" advisory committee, organized by the Japanese government and attended by personages from economic, cultural and academic circles."On this special occasion," Kan said, "Japan is ready to rebuild relations with China in various areas such as culture, economic and politics."According to local media reports, participants at the meeting put forward suggestions such as "China is a promising market in the economic area, and ties with China are thus of great importance" and "people-to-people exchanges need to be promoted in areas of culture, sports and arts."The committee is scheduled to submit the final advisory report to the government in mid-April.

SAN FRANCISCO, April 22 (Xinhua) - Amazon's web-services disruption issues have not been completely resolved Friday morning, as some websites still in slow recovery.Amazon said in an update early Friday that meaningful progress has been made and is expected to continue over the next few hours.Reddit, a social news website, said on its homepage that "we are slowly getting our capacity back," and users may be able to log in if lucky. Some sites appeared to have recovered, including location-based social networking site Foursquare and HootSuite, an online brand management and social websites monitoring service.Amazon has not released the number of companies which have been disrupted by the outage and when the web-services will fully recover.The outage highlights risks of relying on public cloud service. Security and reliability have been experts' concerns on public could web-hosting service. Many Internet startups have been relying on the service to bring their costs down.Elastic Compute Cloud (EC2) is a central part of Amazon's cloud computing platform Amazon Web Services. It allows users to rent virtual computers on which to run their own computer applications. The European Space Agency, PBS and Ericsson are all among its cloud service customers.According to Amazon's Service Health Dashboard, errors began at 1:41 a.m. PDT Thursday in its datacenter in northern Virginia, saying "instance connectivity, latency and error rates."
