SAN FRANCISCO, April 27 (Xinhua) -- Apple Inc. on Wednesday denied the alleged location-tracking practice of its mobile operating system, saying it will release software updates to make iPhone store less location information to quell public concerns over privacy.CLARIFICATION"Apple is not tracking the location of your iPhone. Apple has never done so and has no plans to ever do so," the company said in a statement."Users are confused, partly because the creators of this new technology (including Apple) have not provided enough education about these issues to date."According to the statement, the location data researchers saw on iPhone is a database of Wi-Fi hotspots and cell towers around users' current location that Apple is maintaining to help iPhone rapidly and accurately calculate its location when requested. It noted Apple cannot locate iPhone users based on Wi-Fi hotspot and cell tower data as the information is in an anonymous and encrypted form.Apple admitted that part of the location data (Wi-Fi hotspots and cell towers) is backed up on iTunes, which means it could be possible that people with access to iPhone users'computer may get their location information. It said a software update has been planned to cease the backing-up.It is also planning to provide an update to limit the data storage on iPhone, in response to questions that the device has been storing location data since the release of iOS 4 operating system last June.Apple said it is a bug that iPhone keeps storing location data even if its location services are disabled, noting it will fix this through a software update in the coming weeks.The company also reiterated its focus on personal information security and privacy."Pretty much what I expected at this stage. The response is measured and the update should fix the problem," Alasdair Allan, one of the two British researchers who first announced the discovery of stored location data on iPhone, said on his Twitter account.ALLEGATIONThe statement on Wednesday is Apple's first official response to the location-tracking allegations.Worries on the iPhone tracking issue first surfaced last Wednesday when two British researchers announced at a technology conference in California that iPhone has been collecting users' location information and storing the data since June 21, 2010.Last Friday, The Wall Street Journal reported its security analysts had 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.The newspaper then reported on Sunday that its analysts had also found iPhone is collecting and storing user's location data even when location services are turned off.PRESSUREThe Cupertino, California-based company has been facing mounting pressure from lawmakers, customers as well as media reports following the revelations.The U.S. House Energy and Commerce Committee on Monday sent letters to six developers of mobile device operating systems, including Apple and Google, demanding Apple's explanation on implications of alleged tracking for individual privacy and federal communications policy.Also on Monday, Minnesota Senator Al Franken, chairman of the U. S. Senate Judiciary Subcommittee on Privacy, Technology and the Law, announced he had scheduled a mobile privacy hearing on May 10 and asked representatives from Apple and Google to speak at the hearing.Meanwhile, Lisa Madigan, Attorney General of U.S. state of Illinois, on Monday called for a meeting with Apple and Google executives on the location-tracking reports, citing her ongoing effort to protect consumers' personal information online.Last Friday, two iPhone users filed a class action suit against Apple in Tempa, Florida, accusing the company of invasion of privacy and computer fraud and seeking a judge's order to bar the alleged data collection.Last Thursday, U.S. congressman Edward Markey asked Apple CEO Steve 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."On Saturday, Markey called for a congressional investigation into the privacy practices of Apple and Google. In a statement, he made clear that he thinks the data collection is potentially dangerous, saying predators could have hacked into an iPhone or Android phone to find out children's location information.Apple is also reportedly being investigated in South Korea, France, Germany and Italy over the alleged tracking practice.

LOS ANGELES, May 2 (Xinhua) -- An asteroid will fly past Earth this fall at a close approach that will allow a close-up view of one of Earth's good-sized space rocks, NASA's Jet Propulsion Laboratory (JPL) announced on Monday."On November 8, asteroid 2005 YU55 will fly past Earth and at its closest approach point will be about 325,000 kilometers away," said Don Yeomans, manager of NASA's Near-Earth Object Program Office at the JPL in Pasadena, Los Angeles."This asteroid is about 400 meters wide -- the largest space rock we have identified that will come this close until 2028."Despite the relative proximity and size, "YU55 poses no threat of an Earth collision over, at the very least, the next 100 years, " Yeomans said in a press release."During its closest approach, its gravitational effect on the Earth will be so miniscule as to be immeasurable. It will not affect the tides or anything else.""While near-Earth objects of this size have flown within a lunar distance in the past, we did not have the foreknowledge and technology to take advantage of the opportunity," said Barbara Wilson, a scientist at JPL. "When it flies past, it should be a great opportunity for science instruments on the ground to get a good look.""The best resolution of the radar images was 7.5 meters per pixel," said JPL radar astronomer Lance Benner. "When 2005 YU55 returns this fall, we intend to image it at 4-meter resolution with our recently upgraded equipment at the Deep Space Network at Goldstone, California. Plus, the asteroid will be seven times closer. We're expecting some very detailed radar images."Asteroid 2005 YU55 was discovered in December 2005 by Robert McMillan, head of the NASA-funded Spacewatch Program at the University of Arizona, Tucson. The space rock has been in astronomers' crosshairs before.In April 2010, Mike Nolan and colleagues at the Arecibo Observatory in Puerto Rico generated some ghostly images of 2005 YU55 when the asteroid was about 2.3 million kilometers from Earth.

LOS ANGELES, May 23 (Xinhua) -- NASA's Gravity Recovery And Interior Laboratory spacecraft (Grail) will begin final preparations for a launch on a Moon mission in late summer, the Jet Propulsion Laboratory (JPL) said on Monday.The dynamic duo will orbit the moon to determine the structure of the lunar interior from crust to core and to advance understanding of the thermal evolution of the moon, according to JPL in Pasadena, Los Angeles.After arriving at the Astrotech payload processing facility in Titusville, Florida last week, the Grail twins, known as Grail-A and Grail-B, were removed from their shipping containers Monday. Later this week, they will begin functional testing to verify their state of health, said JPL.The twins were shipped from Lockheed Martin Space Systems, Denver.Over the next four months at the Astrotech facility, the spacecraft will undergo final testing, fueling and packaging in the shroud that will protect them as the Delta II launch vehicle lifts them into space. The spacecraft will then be transported to the Cape Canaveral Air Force Station for installation atop the rocket that will carry them toward the moon, JPL said."We're only a few full moons away from a mission that will reveal clues not only into the history of the moon and Earth, but will provide important data for future lunar exploration," said Maria Zuber, Grail's principal investigator, based at the Massachusetts Institute of Technology.Grail will be carried into space aboard a United Launch Alliance Delta II Heavy rocket lifting off from Launch Complex-19 at the Cape Canaveral Air Force Station in Florida. The launch period opens Sept. 8, 2011, and extends through Oct. 19. For a Sept. 8 liftoff, the launch window opens at 5:37 a.m. PDT (8:37 a.m. EDT) and remains open through 6:16 a.m. PDT (9:16 a.m. EDT).Grail-A and Grail-B will fly in tandem orbits around the moon for several months to measure its gravity field in unprecedented detail.The mission will also answer longstanding questions about Earth' s moon, and provide scientists a better understanding of how Earth and other rocky planets in the solar system formed, according to JPL, which manages the Grail mission.

SANAA, Feb. 6 (Xinhua) -- In response to earlier reports that a Chinese-flagged commercial ship was hijacked by Somali pirates off Yemeni coast, the China Maritime Search and Rescue Center (MSA) said Sunday that the ship has never been hijacked, and is now sailing safely with escort of the Chinese anti-piracy navy fleet.Both the "Tien Hau" ship, which was registered in Hong Kong, China, and its 22-member crew, are safe, a MSA official confirmed to Xinhua over the phone. The center contacted the ship to make sure it was safe, he added.The ship had been followed by a suspicious boat for a while, but it was never attacked or hijacked, the official said.Earlier, Yemeni Interior Ministry had said the ship was hijacked by pirates some 20 kilometers off the Yemeni island of Al-Tair off the city port of al-Hudaida, and was heading to Somali coast.The Gulf of Aden is considered as one of the world's most dangerous waters because of rampant piracy.

ADDIS ABABA, Jan. 28 (Xinhua) -- Fruitful results have been achieved some one year after the fourth ministerial meeting of the Forum on China-Africa Cooperation (FOCAC), Chinese envoy and Assistant Foreign Minister Liu Zhenmin told Xinhua here on Friday.Liu was in the Ethiopian capital Addis Ababa to attend the 16th African Union (AU) summit as special envoy of the Chinese government.During the FOCAC ministerial meeting held in November 2009 in Sharm el-Sheikh, Egypt, the Chinese government announced eight new measures of promoting Sino-African cooperation.Since then, China has been actively implementing various programs and projects according to the eight new measures, Liu said.The “China-Africa Science and Technology Partnership Program” and the “China-Africa Joint Research and Exchange Program” have been launched, Liu said, adding that the aid program of agricultural demonstration center is in smooth implementation process.Meanwhile, China is actively working on establishing the China-Africa partnership in addressing climate change, and is strengthening communication and coordination with Africa on the issue of climate change, Liu said.The Chinese envoy added that various programs and events such as the China-Africa Agricultural Cooperation Forum, the “African Culture in Focus 2010” activities, and the “20+20 Cooperation Plan of Chinese and African Institutions of Higher Learning” have been launched or successfully held. He said these events have promoted the comprehensive development of China-Africa relations.A wide range of other measures are also being carried out in an active manner, according to Liu.The year 2011 is key to the implementation of the measures announced on the fourth ministerial meeting of FOCAC, Liu stressed.To this end, China will continue strengthening communication and coordination with African countries, carrying out close cooperation and pushing forward the development of the China-Africa new strategic partnership, he pledged.
