SAN FRANCISCO, Aug. 10 (Xinhua) -- Amazon on Wednesday launched Kindle Cloud Reader, a web-based app that may help the on-line retailer to sidestep Apple's App Store restrictions.In its announcement, Amazon said Kindle Could Reader uses the HTML5 web standard to let users read e-books from their Kindle library from the Safari browser or Google's Chrome browser on their desktops or tablet, including the iPad.Support for Internet Explorer, Firefox and the Blackberry Playbook will be launched later this year.The app has a button linked to the Kindle Store, which was removed recently from the Kindle apps for iPad and iPhone.The move is taken as an answer to Apple's latest App Store restrictions, which banned developers to have any external links for purchasing digital books or subscriptions in the app, unless they give Apple a 30 percent cut from the in-app sales.Besides Amazon, Barnes & Noble, Google Books and Canadian e- book seller Kobo have also altered their iPad and iPhone apps to comply with the rules.Meanwhile, publishers and retailers have been developing web- based HTML5 apps to sidestep Apple for more control, which is an approved-of technology for iOS devices.The Financial Times, Kobo and video-on-demand service Vudu have recently launched their HTML5 app to avoid paying Apple a 30 percent cut.Industry watchers said it is unknown how Apple will deal with such apps. It would be easy for Apple to disable Web apps in the iPad's Safari browser, but the company would certainly face some backlash, said tech media website CNET.

BEIJING, July 14 (Xinhuanet) -- European music service Spotify is set to launch in the United States on Thursday, according to media reports.The streaming service will be available in the morning by invitation and through subscription."Spotify is a new way to listen to and manage your music, discover new tracks and share songs and playlists with friends – music whenever you want it, wherever you are," the company said in a statement.Spotify's streaming music and subscription service have long been popular in Europe since its launch in late 2008, and the company has been aiming for a US launch for nearly as long.Spotify has inked agreements with Sony Corp Music Entertainment, EMI Music, and Vivendi SA's Universal Music Group in the last few months. It is expected to close a deal with Warner Music Group by launch or soon after, according to a source.

JOHANNESBURG, June 1 (Xinhua) -- An estimated 2 million adolescents ages 10 to 19 are living with HIV, with 86 percent of them from sub-Saharan Africa, according to a global report on HIV prevention launched in Johannesburg on Wednesday.For the first time, the world gets to see the number of adolescents between the ages of 10 to 19 living with HIV in the report named Opportunity in Crisis: Preventing HIV from early adolescence to young adulthood.The report is a jointly publication by the United Nations Children's Fund (UNICEF), UNAIDS, the United Nations Educational, Scientific and Cultural Organization (UNESCO), the United Nations Population Fund (UNFPA), the International Labor Organization (ILO) , the World Health Organization (WHO) and World Bank.According to the report, people aged 15-24 accounted for 41 percent of new infections over the age of 15 in 2009. Worldwide, an estimated 5 million young people in that age group were living with HIV in 2009. Most of them live in sub-Saharan Africa. Globally, young women make up more than 60 percent of all young people living with HIV. In sub-Saharan Africa that rate jumped to 72 percent.Despite these challenges, the report acknowledges that some progress has been made in preventing new infections among young people."In many high-burden countries, HIV prevalence and incidence have declined among young people. While in 2001 there were 5.7 million young people living with HIV, the figure stands at 5 million (in 2009)," said the UNICEF eastern and southern Africa regional director, Elhadj As Sy, at the media briefing.He pointed that sexual transmission and injection drug use remain the major modes of transmission of HIV among young people. Early sexual debut, early pregnancy and early experiences with drug use all raise risks for HIV infection.The report reveals that unemployment and poverty are reported as the main reasons young people enter the sex trade. Worldwide, many young people driven by economic pressure, exploitation, social exclusion and lack of family support turn to commercial sex and injecting drug use.In 2001, the world made a commitment to reduce the prevalence of HIV among young people by 25 percent by 2010. The actual reduction achieved (from 5.7 million to 5 million) is 12 percent, and it represents less than half the target percentage."To avoid the current programming failures, we have to adopt a ' Continuum of Prevention Approach'." said Lina Mousa, deputy director of UNFPA Africa Regional Office."This continuum of prevention must be reflected in national HIV strategic plans, poverty reduction strategies and global fund proposals. This response must be developed with and for young people so that they own the response together with their communities," she added.To build this continuum of prevention for adolescents and young people, the reports outlined nine specific recommendations including providing young people with information and comprehensive sexuality education, strengthening child protection and social protection measures, engaging communities in shaping a positive social environment that promotes healthy behavior, establishing laws and policies that respect young people's rights.

BEIJING, Sept. 26 (Xinhua) -- Nobel laureates on Monday cast doubt on a European experiment that purportedly demonstrated the ability of neutrinos to move faster than the speed of light.They made the remarks in Beijing prior to a forum for Nobel laureates."I'm willing to bet money that it's not correct," said Professor George Smoot III, winner of the 2006 Nobel Prize in Physics and a professor at University of California, Berkeley, referring to an experiment result claiming that particles apparently travel faster than light.The experiment reported an anomaly in the flight time of neutrinos, or electrically neutral subatomic particles, from the European Center for Nuclear Research (CERN) in Switzerland to a laboratory located 730 kilometers away in Italy.Particles were clocked transmitting at a speed of 300,006 kilometers per second, about 60 nanoseconds faster than the speed of light.Smoot said that the claims "did not make sense" and should be verified by other scientists first."There are many distortions in physics. You have to have a very high standard to see if something is truly correct," he said.The unverified findings were published on Sept. 22 in the scientific journal Nature. European researchers working in a team called OPERA (Oscillation Project with Emulsion-Racking Apparatus) projected masses of neutrinos from CERN and then collected the particles using a massive detector in Gran Sasso, south of Rome.Other scientists, as well as the OPERA team themselves, have voiced doubts regarding the experiment's results.The findings, CERN claims, could pose far-reaching potential consequences once verified.If correct, the results would bring Einstein's theory of special relativity into question. Under this theory, a physical object cannot travel faster than the speed of light in a vacuum."If really it is right, we have to rethink everything we know," said Chris Llewellyn Smith, former director of CERN.Smith claimed the unprecedented discovery was too exceptional to find proof."If somebody makes a very exceptional claim, then very exceptional proof would need to come from another experiment, saying the same thing. But we don't have the other thing," Smith said.Carlos Rubbia, a Nobel Laureate who won the prize for physics in 1984, is in charge of a team of more than 100 scientists at CERN."What it is pretending to find, in my view, is unbelievably surprising," Rubbia said."Frankly, I have the feeling that this is still a very experimental consideration," Rubbia said.He also believes that revealing the findings to the public was a mistake as it remained an experimental process and no conclusion could be drawn without the results of another experiment.Despite the possibility of verification, Einstein's special theory of relativity will remain valid."I will be very, very surprised that, at last, Einstein will not be the winner," Rubbia said.To achieve a breakthrough, Rubbia has urged for more joint cooperation on verifying the test results. International cooperation on this issue "is a must.""It requires coordination from all nations," said Rubbia.The 2011 Nobel Laureates Beijing Forum will be held from Sept. 28 to 30 under a theme of "innovation and development."

BEIJING, Sept. 6 (Xinhuanet) -- A short-term memory loss may suggest the Alzheimer's disease, according to a new study made by Spanish researchers.The finding was published on Monday, in Archives of General Psychiatry, an American Medical Association journal.The researchers gathered data of 116 people with mild cognitive impairment (MCI) who developed Alzheimer's disease within two years, 204 patients with the condition who didn't develop Alzheimer's and 197 people with no cognitive problems.Mild cognitive impairment is usually marked by difficulties with short-term memory, such as losing your train of thought repeatedly or having trouble remembering what you did yesterday, according to the study.After assessing them by biomarker tests and cognitive measures, the researcher found the cognitive markers can forecast the variance."Remarkably, they accounted for nearly 50% of the predictive variance," said Dr. Gomar of Centro de Investigation Biomedica en Red de Salud Mental, Barcelona, who led the research.Mild cognitive impairment at the start of the study was a stronger predictor of Alzheimer's than most biomarkers, the researchers concluded.
