RIO DE JANEIRO, Aug. 31 (Xinhua) -- The Brazilian city of Rio de Janeiroe may have an unprecedented dengue fever epidemic next summer, its mayor warned on Wednesday.The increasing number of dengue fever cases in the past few months shows similarities to the months predecing the 2002 and 2008 epidemics, Mayor Eduardo Paes said."Everything points to a new cycle of the disease, certainly the worst epidemic in Rio's history," he said.In 2008, Rio registered some 250,000 cases of dengue fever, with 174 people confirmed dead from the disease. In 2002, Rio had some 290,000 dengue fever cases and 91 people died.In efforts to halt the spread of the disease, Paes has declared a state of alert and is determined to take a series of measures to eliminate the habitat of the Aedes aegypti mosquito, which transmits dengue fever through its bite.Paes also announced an increase in the number of health care units for dengue fever patients. The total cost of a dengue prevention and combat program, which is expected to last until April 2012, will reach 42 million reais (26.25 million U.S. dollars).There is no vaccine against dengue fever, but Brazilian scientists are currently working on one which will immunize against four types of the disease.

BEIJING, Sept. 20 (Xinhuanet)-- Google's executive chairman Eric Schmidt is to face a Senate hearing on whether the company is abusing its dominance in Internet search, according to media reports on Tuesday.At the Wednesday's hearing before the Senate Judiciary Committee's antitrust panel, Schmidt will argue that critics are wrong to say Google gives preference to its own products, instead, Google is just trying to deliver the best-cultivated search results for users. The issue of search ranking is a touchy subject with Google, which says its algorithm is devised to give users the most useful result so they will come back.Another focal point of the hearing, which Schmidt concerned most is "scrapers", those who game its search algorithm, for example, taking commonly searched words, combine them into a nonsensical block of text and throw it up on the Web to grab eyeballs and advertising dollars.Google believes that, if scrapers succeed too often, consumers will lose confidence in search and turn to other resources, thus posing an existential threat to the company.Regulators in the U.S. and abroad have been looking into various aspects of Google's business practices since the company's 2007 purchase of ad firm DoubleClick. At the moment, European regulators are conducting an antitrust inquiry into Google's search business while the Federal Trade Commission is doing likewise. Google relies overwhelmingly on its core product, Internet search, and dominates the market for that product. It handles around two-thirds of U.S. Internet searches and more than 80 percent in many European countries, according to comScore Inc.

BEIJING, Sept. 6 (Xinhuanet) -- San Francisco police said they had helped Apple search for a "lost item," following reports saying that a prototype of Apple's yet-to-be-released iPhone 5 had gone missing in July.Last week, technology news website CNET reported that an Apple employee lost at a tequila bar in San Francisco in July a prototype of iPhone 5, a new version of the company's mobile phone expected to be released in September or October.The San Francisco Police Department said in a press release that after the missing device was tracked using GPS technology to a San Francisco house, four police officers and two Apple employees visited the home."Apple employees called Mission police station directly, wanting assistance in tracking down a lost item," the statement said."The two Apple employees met with the resident and then went into the house to look for the lost item," it said. "The Apple employees did not find the lost item and left the house."Police did not say exactly what Apple had lost, but media reports found the file of San Francisco police's Friday press release about the hunt was named "iphone5.doc" -- an apparent hint of the new mobile device.A 22-year-old resident of the home, identified by SF Weekly as Sergio Calderon, told the newspaper that he has visited the bar where the phone was reportedly lost but he did not have the device.Calderon said the search of his house took place in July when police had traced the phone to the house using satellite positioning software on the device, but did not find anything in the house.Apple has declined to comment on the matter.Last year, an employee of the company lost a prototype iPhone 4 in a Redwood City bar before it was released. The details of the phone ware then unveiled by technology blog Gizmodo.Criminal charges have been filed against the man who found the prototype and another who brokered the deal to sell it to Gizmodo. Both men pleaded not guilty on Thursday.

SYDNEY, Aug. 16 (Xinhua) -- People sitting in front of TV for hours on end could shorten their life expectancy by almost five years, according to an Australian study published on Tuesday by the British Journal of Sports Medicine.Researchers from the University of Queensland estimate that for every hour adults spend in front of TV, their life expectancy shortens by almost 22 minutes.Those who watched six hours a day lived 4.8 years less than those who don't watch TV.The study is the first in Australia to look into how TV habits affect longevity.The Australian researchers found that watching TV could have a similar negative impact on life expectancy to that of obesity, smoking and low physical activity."People don't realize how it all adds up," the study's lead author Dr. Lennert Veerman told the Australian Associated Press (AAP)."They should try not to watch too much TV and find alternative things to do, preferably things that are light activities," Veerman said.The study was based on data from the Australian Diabetes, Obesity and Lifestyle study and asked more than 11,000 people aged over 25 about their weekly TV viewing time.The study found that in 2008 Australian adults watched 9.8 billion hours of TV."These findings suggest that substantial loss of life may be associated with prolonged TV viewing time among Australian adults," the study said."TV viewing time may have adverse health consequences that rival those of lack of physical activity, obesity and smoking; every single hour of TV viewed may shorten life by as much as 22 minutes," it said."With further corroborative evidence, a public health case could be made that adults also need to limit the time spent watching TV."Australians are recommended to spend at least 30 minutes a day doing moderate-intensity physical activity to reduce an increased risk of developing cardiovascular disease.
