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, March 16 (Xinhua) -- The death rate in the United States reached an all-time low in 2009, dropping 2.3 percent from 2008, a newly released report said.This was the 10th straight year of decline, demonstrating that Americans are living longer than ever, according to the report from the U.S. Centers for Disease Control and Prevention's National Center for Health Statistics.The nation saw a drop from 758.7 deaths per 100,000 people in 2008 to 741 per 100,000 people in 2009 when 2,436,682 deaths were reported, said the report published by HealthDay News on Wednesday.However, life expectancy for blacks remained unchanged -- 70.9 years for men and 77.4 years for women. The disparity between whites and blacks is now 4.3 years, representing a 0.2 percent increase from 2008 to 2009, the report found.The report said that deaths fell in 10 of the 15 leading causes of death -- heart disease dropped 3.7 percent, cancer fell 1.1 percent, and stroke declined 4.2 percent.Deaths from Alzheimer's disease, diabetes, chronic lower respiratory diseases and accidents all declined 4.1 percent, according to the report.Deaths from flu and pneumonia fell 4.7 percent, and deaths from septicemia, a bacterial infection, decreased 1.8 percent, the report said.Deaths from homicides fell 6.8 percent, but suicides increased from 35,933 in 2008 to 36,547 in 2009. Other than suicide, which overtook septicemia as the 10th leading cause of death, the ranking of the leading causes of death was unchanged from 2008 to 2009, the report noted.Infant mortality hit a record low in 2009, falling from 6.59 deaths per 1,000 births in 2008 to 6.42, representing a 2.6 percent decrease, according to the report.The report, however, did not give reasons for these trends.Experts think behavioral changes, particularly the decline in smoking, are partly responsible for the improvements.The report's lead author Kenneth Kochanek, a statistician at the center, said this is preliminary data, and the final data, which should be available this summer, may shed some light on the findings.

BEIJING, Feb. 15 (Xinhua) -- China's health authorities Tuesday vowed to improve their response to food safety incidents.The ministry would issue a protocol "as early as possible" on how to respond to and investigate food safety incidents, said Vice Health Minister Chen Xiaohong at a national meeting on food safety in Beijing.It would also provide better training for officials and professionals working in the field, Chen said.Last year, the ministry initiated investigations into several incidents such as milk powder that allegedly caused infant girls to grow breasts and illegal soup additives by restaurants.In the milk powder case, the investigation found no evidence that Synutra International's products had caused the problem. Media reports said the company was the victim of dirty tricks by a rival firm.In addition, the ministry blacklisted 48 substances illegally added to food and 22 misused food additives last year.The ministry would include projects related to food safety in state-sponsored health programs giving free medical services to the public in next five years, Health Minister Chen Zhu said at the same meeting.But Chen did not give details about what kind of projects they will be.Under the current six state health programs, the government provides free cataract surgery for the needy, free breast and cervical examinations for rural women, free hepatitis B vaccines, free folic acid pills for rural women, new cooking stoves in rural homes to prevent fluorine poisoning caused by coal stoves as well as modern toilets for rural residents.

JINAN, May 14 (Xinhua) -- Chinese scientists said Saturday that they have found a new species of giant theropod dinosaur in the eastern province of Shandong.The new species, described as a close relative of Tyrannosaurus rex (T. rex), has been named "Zhuchengtyrannus magnus". Paleontological experts found it has unique upper jawbones after examining the skull and jawbones discovered in the city of Zhucheng.It was estimated to be about 11 meters long and 4 meters tall, weighing close to 7 tonnes."We discovered two kinds of tyrannosaurus fossils here and the identity of the other one still remains unclear," said Xu Xing, a researcher at the Institute of Vertebrate Paleontology and Paleoanthropology under the Chinese Academy of Sciences."We've named the new genus Zhuchengtyrannus magnus, which means the 'Tyrant from Zhucheng' because the bones were found in Zhucheng," Xu said.The bones were a few centimeters smaller than the similar bones in the largest T. Rex specimen, so there was no doubt that Zhuchengtyrannus was a huge tyrannosaur, Xu said.According to Xu, Zhuchengtyrannus magnus belonged to a specialized group of gigantic theropods called tyrannosaurines which existed in North America and eastern Asia during the Late Cretaceous Period that dated back about 65 to 99 million years.All tyrannosaurs were carnivorous, bipedal animals that generally had small arms and large skulls. Among the tyrannosaurs, the tyrannosaurines were the largest and characterized by having just two fingers on each hand and large powerful jaws to deliver a bone crushing bite. They were likely both predators and scavengers.The fossil quarry in Zhucheng contains one of the largest concentrations of dinosaur bones in the world. At least 10 dinosaur species have been found in three rounds of excavations since the 1960s, including Tyrannosaurus and Hadrosaurs.
