BEIJING, May 12 (Xinhuanet) -- Italian archaeologists are digging the remains of Lisa Gherardini, a 16th-century woman who is widely believed to be the model for the famous portrait Mona Lisa, AFP reported on Wednesday.The team of historians say they will try to find the remains using geo-radar equipment and then try to re-create a likeness of what the woman, Lisa Gherardini, would have looked like to compare her to Leonardo Da Vinci's Mona Lisa.Gherardini (1479-1542), also known by her married name as Lisa del Giocondo, was the wife of a Florentine silk merchant and is widely believed to have been the model for the  portrait that now hangs in the Louvre in Paris.But the issue has never been settled definitively and mystery still shrouds the model's enigmatic expression and other details of the portrait.

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.

BEIJING，March 11 (Xinhuanet) --A poor diet during pregnancy may result in health problems such as diabetes for the offspring in later life, according media reports Friday quotting a new research.Based on a study of rats, researchers from the University of Cambridge altered the protein content of the mother's diet during pregnancy as they found that rats were more vulnerable to the effects of diseases if their mothers were malnourished while they were pregnant.Further, the study also showed that an imbalanced diet in the expectant mother can compromise the long-term functioning of a gene in the child. And the gene, named Hnf4a, is believed to play a major role in the development of the pancreas and in the production of insulin.The researchers held similar mechanisms seen in the rat study could occur in humans, and that the effects might be felt by more than just the immediate offspring."What is most exciting about these findings is that we are now starting to really understand how nutrition during the first nine months of life spent in the womb shape our long term health by influencing how the cells in our body age," said Susan Ozanne, senior author of the paper and senior fellow from the Institute of Metabolic Science at the University of Cambridge.And Jeremy Pearson, associate medical director at the British Heart Foundation, said: "The reasons why are not well understood, but this study in rats adds to the evidence that a mother's diet may sometimes alter the control of certain genes in her unborn child.""It's no reason for expectant mothers to be unduly worried. This research doesn't change our advice that pregnant women should try to eat a healthy, balanced diet," he added.

BEIJING, Jan. 23 (Xinhua) -- Three years ago when Jason Shen stood on the Times Square for the first time, he didn't expect that a video clip he produced could be shown at the "Crossroads of the World"."In the eyes of an advertisement specialist, Times Square is a dream, where the biggest screen was as tall as a four-storey building and every day about 70,000 passengers could see the ads," said the chief executive officer of Shanghai Lowe & Partners advertising company.The company won the bidding of producing China's national publicity video in November 2009."Our biggest challenge was how to show a real China within just 60 seconds," he recalled.After brainstorming, his team agreed that the main theme should be human beings."The persons appearing in the video clip were like messengers to convey China's friendliness to the world," he said.The video was a step China takes in its foreign relations efforts, and a chance for Shen individually to fulfill a dream.Working as the chief executive producer, Shen gave some details in the filming of the video."Famous actress Zhang Ziyi was a very amiable person," he said. "She was very cooperative and the dress she wore was decided by arranged by our team."John Woo was excited hearing about the plan to make such a national publicity video work. "He told me that it was like reviewing the excitement when hearing China won the bidding of the 2008 Beijing Olympics."Deng Yaping, the four-time Olympic table tennis champion, was not sure how to pose in front of the camera."I told her that she just need to smile like when Ex-Olympic Chief Juan Antonio Samaranch put the gold medal around her neck," Shen said.All celebrities agreed to appear in the video free-of-charge.The smiling faces at the end of the 60-second video were gathered at the Shanghai World Expo, when it was hot and the temperature reached 40 degrees Celsius.But Shen and his team were left with some pity. "It was not easy to have six astronauts including Yang Liwei in the filming. But we could have made the video more lively by asking them to change more poses," he said.After the video was aired, Shen was sometimes questioned if the 59 persons in the short video could represent the entire of China."A good advertisement should give audiences strong visual impact and be enlightening," he said. "I believe that the celebrities and ordinary people from all walks of life could represent a mild and elegant image of China."The 60-second national publicity video is shown 15 times every hour on the Times Square from January 17 to February 14. It is expected to be aired on CNN from January 17 to February 13.A 15-minute documentary produced by the team, which is to be used at important events of Chinese embassies, was also finished. It will show the beautiful scenery of China.
