WASHINGTON, April 25 (Xinhua) -- The U.S. National Aeronautics and Space Administration (NASA) and the U.S. Agency for International Development (USAID) have agreed to expand their joint efforts to overcome international development challenges such as food security, climate change, and energy and environmental management.NASA Administrator Charles Bolden and USAID Administrator Rajiv Shah signed a five-year memorandum of understanding on Monday, at NASA Headquarters. The agreement formalizes ongoing agency collaborations that use Earth science data to address developmental challenges, and to assist in disaster mitigation and humanitarian responses. The agreement also encourages NASA and USAID to apply geospatial technologies to solve development challenges affecting the United States and developing countries."Technologies for NASA missions have long improved life here on Earth. Together with USAID, we'll meet even more sustainable development challenges here on the ground, solving problems for the world community," Bolden said in a statement. "As we explore space, we'll also be exploring solutions to important health, nutritional and safety challenges in developing countries."The agencies will continue collaborations to stimulate innovative science and technology solutions to international development challenges by using Earth science data, research results, computer models, visualization applications and remote- sensing techniques.USAID is the lead federal development agency implementing U.S. development efforts through field-based programs and projects around the world. NASA has broad experience with Earth science research, development of Earth science information products, and technology applications."Through our partnership with NASA, we can apply the latest, cutting-edge technology to deliver meaningful results for people in developing countries in areas like health, food security and water," Shah said. "It's a prime example of our efforts to use the power of science and technology to tackle today's pressing development challenges."Since 2003, NASA and USAID have worked together building and expanding the SERVIR program, which allows people in developing regions to use Earth observations for addressing challenges in agriculture, biodiversity conservation, climate change, disaster response, weather forecasting, and energy and health issues.The agencies also collaborate on the LAUNCH program, which supports science and technology innovators in the nonprofit and private sectors. The program's goal is improving innovations to achieve greater impact on sustainability issues.

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.

WASHINGTON, May 27 (Xinhua) -- The U.S. Treasury Department said in a report released on Friday that China was not manipulating its currency."In China, since the authorities decided in June 2010 to allow the exchange rate to appreciate in response to market forces, the renminbi (RMB) has appreciated by a total of 5.1 percent against the dollar in nominal terms through the end of April 2011, or at an annual pace of approximately 6.0 percent," noted the semi- annual report on international economic and exchange rate policies.The Treasury said that as inflation in China is significantly higher than it is in the United States, the renminbi has appreciated more rapidly against the dollar on a real, inflation- adjusted basis, at a rate of around 9 percent per year.The delayed report, which was originally scheduled to be sent to the Congress on April 15, finds "no major trading partner of the United States" manipulated its currency during the period covered in the report.The Treasury added that it will continue to "closely monitor" the renminbi appreciation pace.The report also noted that the U.S. economy is recovering from its deepest recession in the post-war period."While recent growth is encouraging, the economy still faces significant challenges," said the report. The number one challenge is still in the labor market.The U.S. unemployment rate, currently at 9.0 percent, is not expected to fall significantly this year.Besides, housing market and long-term fiscal position are " unsustainable," according to the report.In recent remarks, Treasury Secretary Timothy Geithner stated that China is the fastest growing market for U.S. exports. In 2010, U.S. exports to China grew at a pace that was 50 percent higher than the rest of the world.

BEIJING, Jan. 29 (Xinhua) -- Chinese State Councilor Dai Bingguo and U.S. National Security Advisor Tom Donilon on Saturday both spoke highly of Chinese President Hu Jintao's state visit to the United States earlier this month.During a phone conversation, Dai and Donilon agreed that China and the United States should make joint efforts to properly implement the consensus reached by leaders on both sides and cement the achievements made during Hu's visit, which was on Jan. 18-21.They also said that the two sides should maintain the current momentum in the development of bilateral ties and devote themselves to building a cooperative partnership based on mutual respect and mutual benefit.

BEIJING, Jan. 20 (Xinhua) -- Major foreign media have been positive in their coverage so far of Chinese President Hu Jintao's four-day visit to the United States, which began Tuesday.AP said Obama was lavishing the grandest of White House welcomes on Hu as the leaders of the two powers looked for common ground on economic and security issues without alienating their domestic audiences."I absolutely believe China's peaceful rise is good for the world, and it's good for America," Obama said.The Washington Post said Obama stated several times that the United States does not fear a stronger China and that Washington has no interest in blocking Beijing's emergence as a superpower.Chinese President Hu Jintao speaks at a welcoming ceremony held by U.S. President Barack Obama on the South Lawn of the White House in Washington, the United States, Jan. 19, 2011It also said Hu's visit, in addition to serious policy matters, featured a fair amount of glitz. He arrived at the White House to a 21-gun salute and was sent off with a state dinner.The Wall Street Journal said President Obama is looking to assure Americans that they should not fear China's economic rise, using Chinese President Hu's high-profile state visit to announce job-creating business deals worth billions of dollars to U.S. companies.The two sides played down differences and stressed areas of cooperation, ranging from a plan to cooperate on nuclear security to an extension of the loan of two Chinese pandas to Washington's zoo.CNN said at a joint news conference held by the two leaders, Obama praised a "spirit of cooperation that is also friendly competition." President Hu told reporters the countries' relationship is based on "mutual respect and mutual benefit."Obama stressed common interests between the nations while toasting the Chinese leader at the White House, CNN said.VOA said dozens of business deals this week will increase U.S. exports by more than 45 billion U.S. dollars and increase China's investments in the United States by several billion dollars.AFP said that, during Hu's visit, the United States and China had announced a raft of trade deals worth 45 billion dollars. The deals, spanning sectors as diverse as agriculture, gasification, railways and hybrid buses, would support 235,000 U.S. jobs."The scope of Wednesday's deals were seen as evidence of the rapidly deepening business links between the two countries," AFP said.The Los Angeles Times said in its report that two leaders "unapologetically acknowledged major differences on economic issues and human rights" in a White House summit Wednesday, but also pledged cooperation to stabilize relations between the world's two largest economies.Obama said the United States hoped to benefit from China's "rapid and peaceful" growth, the report said.The Times of India said, "China's President Hu Jintao arrived in Washington on Tuesday on a four-day U.S. visit that is being watched in every capital on the planet."O Estado de S. Paulo, a local daily newspaper in Brazil, quoted President Hu's words, saying that China and the United States "stand to gain from a sound China-U.S. relationship, and lose from confrontation," thus they needed to discard the "Cold War mentality."The newspaper also said the two nations both hoped to take the visit as an opportunity to rebuild mutual trust despite some frictions over the past year.
