SYDNEY, Aug. 25 (Xinhua) -- Scientists in Australia have discovered a way of stopping mosquitoes carrying dengue virus, raising hopes for preventing the 50 million human cases of the disease every year, local media reported on Thursday.Groundbreaking experiments in Queensland have found a common insect bacteria, wMel Wolbachia, which can dramatically reduce the presence of dengue fever in mosquitoes.The research, led by Professor Scott O'Neill, Dean at Melbourne's Monash University, was published on Thursday in the prestigious journal, Nature.Australian researchers working on the Eliminate Dengue program aim to protect the mosquitoes themselves from dengue and so stop them transmitting the virus to humans."What the experiments have shown is that this strain of Wolbachia when it is put into mosquitoes really reduces the ability of the (dengue) virus to grow in the mosquito and if it can't grow, then it can't get transmitted in people," O'Neill told reporters.O'Neill said while it was too early to say if the experiments heralded the end of dengue fever, it was a major step towards that goal.In the past decade, there have been 2400 cases of dengue fever reported during 36 outbreaks in Australia.Dengue fever has become endemic in tropical regions, where it is spread by a specific type of mosquito that becomes infected after biting humans with the disease.Despite millions of people being infected with dengue each year, there is currently no way of stopping its rapid spread either by vaccines or controlling mosquito populations.Further trials will be conducted in Cairns in north Queensland over the coming wet season and approval is currently being sought for trials in Thailand, Vietnam, Brazil and Indonesia that will directly determine the effectiveness of the method in reducing dengue disease in human populations, according to Monash University.

GENEVA, Sept. 26 (Xinhua) -- Two million people worldwide are estimated to die from air pollution each year, the Geneva based World Health Organization (WHO) said in its air quality report published on Monday.According to data collected by the WHO from nearly 1,100 cities across 91 countries, elevated level of fine particle pollution, which could cause heart diseases, lung cancer, asthma and acute lower reparatory infections, are common across many urban areas, with some cities registering fine particle pollution levels 15 times as much as the WHO guidelines.For both developed and developing countries, the biggest contributors to urban outdoor air pollution include motor transport, small-scale manufacturers and other industries, burning of biomass and coal for cooking and heating, as well as coal-fired power plants.Residential wood and coal burning for space heating is said to be an important contributor to air pollution, especially in rural areas during colder months, the WHO report said.

SAN FRANCISCO, Sept. 13 (Xinhua) -- Intel and Google on Tuesday announced a partnership to enable the world's largest chip maker's architecture on the search giant's products, saying that an Intel chip-based Android smartphone will hit the market in the first half of 2012.In a joint press release, the two companies said the future versions of Android mobile operating system will support Intel's low power Atom processors, in addition to other architectures.At the Intel Developer Forum in San Francisco on Tuesday, Intel Chief Executive Officer Paul Otellini said the Intel smartphone chip is code-named Medfield and based on the company's own PC- based computer architecture.Otellini said multiple vendors around the world will launch the Medfield-based Android smartphones in the first half of 2012.Andy Rubin, senior vice president of mobile at Google, came on stage at the close of Otellini's keynote to hail the joint initiatives between the two companies.Intel has been struggling to get a bite of the booming market of smartphones and tablets. Most of the current mobile devices use chips based on architecture from ARM Holdings, which are considered more power efficient than Intel's products. Nokia had planned to ship smartphones with Intel chips this year, but it shifted to ARM-based phones with Windows Phone 7 system.Otellini said Intel will eventually have an advantage in supplying smartphone chips as the business is not established in terms of the final winner and performance of the products keeps growing.

SAN FRANCISCO, June 20 (Xinhua) -- Google and the British Library announced Monday that the Internet search giant will digitize 250,000 out-of-copyright books from the library's collections, making up to 40 million pages from 1700 to 1870 available to the public online.In a joint statement, the British Library and Google said they will work in partnership over the coming years to deliver the content free through Google Books and the library's website, and full text search, download and reading will be available. Google will cover all digitization costs.The project is going to cover a huge range of printed books, pamphlets and periodicals dated 1700 to 1870, a period of political and technological turmoil, from the Industrial Revolution to the French Revolution, from the introduction of the income tax in Britain and the invention of the telegraph and railway.It will include material in a variety of major European languages and will focus on books that are not yet freely available in digital form online, said the statement.Since December 2004, Google has announced partnership with some 40 high-profile university and public libraries, planning to digitize and make available some 15 million volumes within a decade through Google Books service.The project has triggered controversy as publisher and author associations oppose the plan to put copyrighted titles online in a class action lawsuit.

LOS ANGELES, June 5 (Xinhua) -- A latest study has found no evidence that screening for ovarian cancer may reduce the risk of dying from the disease, it was reported on Sunday.Screening, however, does increase the likelihood of unnecessary invasive procedures, according to researchers at the University of Utah.The researchers presented their findings at an on-going meeting of the American Society of Clinical Oncology in Chicago, The Los Angeles Times said.Researchers studied 78,216 women, ages 55 to 74, who participated in the National Cancer Institute's Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial. Half of the women received the usual care from their OB-gyns, and half received a CA 125 screening every year for six years and an ultrasound every year for four years. They were then followed for a maximum of 12 years.The researchers observed 212 ovarian cancers in the screened group and 176 in the normal care group. There were 118 ovarian cancer deaths in the screened group and 100 in the normal care group. The differences were not statistically significant. Overall, there were 2,924 deaths from all causes in the screened group and 2,914 in the normal care group.But the researchers also observed that 3,285 women had false- positive diagnoses from the screening. Among those, 1,080 underwent surgery that included an oophorectomy (surgical removal of one or both ovaries). Fifteen percent of those who had surgery developed major complications as a result. Overall, 1,771 women in the screened group (7.7 percent) had an oophorectomy, compared with 1,304 in the normal care group (5.8 percent)."We conclude that annual screening for ovarian cancer ... does not reduce disease-specific mortality in women at average risk for ovarian cancer but does increase invasive medical procedures and associated harms," the researchers said in the study.New data presented at the meeting also showed that the widely used cancer drug Avastin can improve treatment of ovarian cancer, The Times said.About 21,880 American women are diagnosed with ovarian cancer each year and about 13,850 die from it, according to the American Cancer Society. Because it produces few symptoms, the disease is typically not diagnosed until it has become advanced and spread throughout the body. As a result, five-year survival is only about 30 percent, and the disease is one of the five most deadly cancers among women. Being able to detect the cancer at an earlier stage when it might be more curable could thus, theoretically, improve the survival rate.The tests most commonly used to detect ovarian cancer include a transvaginal ultrasound to look for tumor masses and a blood test that screens for increased levels of a tumor marker called CA 125.
