SAN FRANCISCO, April 22 (Xinhua) -- Apple and Google collect smartphone users' location information as part of their race to build massive databases, The Wall Street Journal reported on Friday after analyzing data and documents.According to the report, security analysts with the newspaper found that Apple's iPhone and smartphones running Google's Android operating system regularly transmit users' locations back to the two companies respectively, which is part of their race to build databases capable of pinpointing people's locations via smartphones.A report by research firm Gartner indicated that the market for location-based services is expected to rise to 8.3 billion U.S. dollars in 2014 from the current 2.9 billion dollars.In the case of Google, a security analyst with The Wall Street Journal said an HTC Android phone collected name, location, signal strength of any nearby Wi-Fi networks, and a unique phone identifier every few seconds and transmitted the data to Google at least several times an hour."All location sharing on Android is opt-in by the user," Google said in a statement to technology blog site All Things Digital, in response to the concern that how Android system uses location information."We provide users with notice and control over the collection, sharing and use of location in order to provide a better mobile experience on Android devices. Any location data that is sent back to Google location servers is anonymous and is not tied or traceable to a specific user," said the statement.Worries on the iPhone tracking issue surfaced on Wednesday after two British researchers announced at a technology conference in California that iPhone has been collecting users' location information and storing the data for extended periods of time.The researchers said starting on June 21 2010, after the release of iOS 4 mobile operating system, iPhones began logging and storing location information in a file, which shows the users' latitude and longitude and is timestamped to the second. They noted the information is not encrypted on the phone or on the iPhone backups made by iTunes and the file is also persistent, transferring itself to a new iOS device when the old one is replaced.They added they had no evidence that the file was being transmitted to Apple.On Thursday, U.S. congressman Edward Markey reacted angrily to the news in a letter to Apple CEO Steve Jobs, which is posted on Markey's official website.Markey asked Jobs to make a response within 15 business days or no later than May 12, saying "Apple needs to safeguard personal location information of its users to ensure that an iPhone doesn't become an iTrack."Apple has made no comment on the issue so far, but a letter it sent to U.S. Congress last July came under spotlight. In the letter, Apple said it collects Wi-Fi and GPS information when the phone is searching for a cellular connection and gathers the data to help build a "database with known location information."

LOS ANGELES, May 6 (Xinhua) -- Limiting prolonged bottle use in children may be an effective way to help prevent obesity, a new study suggests.For the study, researchers from the Center for Obesity Research and Education at Temple University (CORETU) and the Ohio State University College of Public Health analyzed data from 6,750 children to estimate the association between bottle use at 24 months of age and the risk of obesity at 5.5 years of age, according to the Science Daily on Friday.Of the children studied, 22 percent were prolonged bottle users, meaning that at two years of age they used a bottle as their primary drink container and/or were put to bed with a calorie- containing bottle.The findings showed that nearly 23 percent of the prolonged bottle users were obese by the time they were 5.5 years old."Children who were still using a bottle at 24 months were approximately 30 percent more likely to be obese at 5.5 years, even after accounting for other factors such as the mother's weight, the child's birth weight, and feeding practices during infancy," said Dr. Robert Whitaker at CORETU, lead author of the study.Drinking from a bottle beyond infancy may contribute to obesity by encouraging the child to consume too many calories, the researchers noted."A 24-month-old girl of average weight and height who is put to bed with an eight-ounce bottle of whole milk would receive approximately 12 percent of her daily caloric needs from that bottle," explained co-author Rachel Gooze.Gooze noted that weaning children from the bottle by the time they are one year of age is unlikely to cause harm and may prevent obesity. The authors suggested that pediatricians and other health professionals work with parents to find acceptable solutions for stopping bottle use at the child's first birthday.The findings adds new evidence to the theory that obesity prevention should begin before children enter school, the researchers said.

WASHINGTON, May 20 (Xinhua) -- Two U.S. astronauts conducted the first of four spacewalks for space shuttle Endeavour's STS-134 mission on Friday morning, the U.S. National Aeronautics and Space Administration (NASA) said.According to the U.S. space agency, Endeavour's mission specialists Andrew Feustel and Greg Chamitoff completed the six-hour, 19-minute spacewalk at 9:29 a.m. EDT (1329 GMT). They successfully installed antennas for the External Wireless Communication system, routing cables, setting up the antenna, installing handrails, and connecting power cables.Because of a carbon dioxide sensor failure in Chamitoff's spacesuit, flight controllers limited his spacewalk time to about six hours 20 minutes, 10 minutes less than the planned six hours and 30 minutes. There was no indication his suit's carbon dioxide levels would rise. However, they deferred tasks to remove a micrometeoroid debris shield to access and attach some of the connection points.This was the 245th spacewalk conducted by U.S. astronauts. It was Feustel's fourth spacewalk for a total time of 27 hours and 17 minutes, and Chamitoff's first.Endeavour lifted off on Monday morning from Kennedy Space Center in Florida, to deliver to the International Space Station a 2-billion-dollar, multinational particle detector known as the Alpha Magnetic Spectrometer (AMS).AMS, a particle physics detector, is designed to search for various types of unusual matter by measuring cosmic rays. Its experiments are designed to help researchers study the formation of the universe and search for evidence of dark matter, strange matter and antimatter.

PANAMA CITY, April 17 (Xinhua) -- In Latin America there are 600,000 people infected with the Acquired Immune Deficiency Syndrome (AIDS) and about 50 percent of them receive treatment, regional director of UNAIDS for Latin America Cesar Nunez said on Sunday."We have to work a lot for the other half get treatment," Nunez told Xinhua during the 124th Assembly of the Inter-parliamentarian Assembly hosted in Panama City from April 15 to 20.Nunez urged the governments of the region to redouble efforts to control this pandemic, by improving the prevention campaigns to stop new infections."The availability of the medicines has grown in the last 10 years and the countries have taken this commitment, however, the number of infections each time is bigger than the number of people we can treat," he said.According to Nunez, despite the increase of new infections among women, the men sector continue being one of the most affected social groups by this virus."In Latin America we have an epidemic where the most affected are men, followed by homosexuals, lesbians and sex workers," he said.Nunez said that during the meeting with the parliamentarians, they exchanged experiences to contribute to improve the management of this disease."We have met with parliamentarians who have voted for more budget to buy more medicines, in favor of laws for more education about this topic and participation in the exchange of information to know about the advances and backwards of the fight against Aids," he said.Some 800 parliamentarians from 125 countries attended the 124th Assembly to debate the recent events in the Arab world, the disaster in Japan and sustainable development.
