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.

TAIPEI, Jan. 29 (Xinhua) -- Nora Sun, granddaughter of Sun Yat-sen, the forerunner of China's revolution to end feudalism, died Saturday afternoon in a Taipei hospital, about one month after being injured in a car accident.Sun, 72, was severely injured in a car crash while on her way to an airport near Taipei on Jan. 1. She was in stable condition after several operations, but her condition abruptly deteriorated Saturday afternoon, according to hospital officials, without giving additional details.Sun, who spent most of her time in Shanghai, came to Taipei to attend the Flora Expo. While returning to Taoyuan International Airport near Taipei the black sedan Sun was riding in crashed head-on into an oncoming vehicle, described as a red car. Sun had planned to return to Hong Kong that day.Sun's car had been driven by a friend. The driver of the red car, who was believed to be speeding, according to police, died on the spot. Sun, her friend, and an injured passenger in the red car were immediately transported to a hospital. .Sun is the youngest daughter of Sun Fo, son of Sun Yat-sen, the leader of the 1911 Revolution that ended imperial rule in China.

BRASILIA, March 15 (Xinhua) -- A nationwide program aimed at providing internet access to 80 percent of the country's population by 2014 is forging ahead in Brazil, Communications Minister Paulo Bernardo said on Tuesday.The National Broadband Plan (PNBL), with participation of 13 ministries, is coordinated by Bernardo, who explained details about the project on Tuesday along with Joao Santana, president of Telebras, the state-owned enterprise responsible for managing the project.The authorities have criticized companies that offer internet service for failing to spread internet use in Brazil, offering an expensive service with prices amounting to about 50 U.S. dollars monthly, inaccessible to low-income families."We ended 2010 with 34 percent of Brazilian households with Internet access, and service is also very poor. Almost half of connections are of 256 mbps. We are out-of-date, with the aggravating circumstance that the connections are very expensive," Bernardo said.To speed up the process, the government started negotiating with concessionaire phone companies to improve the service quality and lower the price to about 30 reais (18 dollars), which would allow 80 percent of the population to access internet."During (former president) Lula da Silva's government, we developed a program to interconnect all schools with internet access, but we also want the private sector to do its share," he said.

WUXI, Jiangsu, Feb. 17 (Xinhua) -- Chinese Vice Premier Zhang Dejiang said Thursday that developing quality labor and vocational skills would greatly contribute to the social and economic development of the Asia-Pacific region.He made the remarks while delivering a speech at the opening ceremony for the APEC (Asia Pacific Economic Cooperation) Skills Development Promotion Center which was launched in China's eastern city of Wuxi.The Center will play a positive role in enhancing human resources cooperation between APEC members and achieve "inclusive growth" in the region, Zhang said.The Chinese government has always held that human resources are the most important resource in social and economic development, and it would continue to actively take part in APEC activities that encourage regional exchanges and cooperation in human resource development, he said.China would fully support the APEC Skills Development Promotion Project and the development of the center with financial and technical backup, making it a platform for vocational training and personnel exchanges between APEC members, he added.The decision to establish the center was announced by Chinese President Hu Jintao during the 18th APEC Economic Leaders' Meeting in November last year, which sought to advance cooperation on human resources within the APEC framework.

WASHINGTON, May 17 (Xinhua) -- A variation in a gene involved in regulating cholesterol in the bloodstream also appears to affect progesterone production in women, making it a likely culprit in a substantial number of cases of their infertility, a new study from Johns Hopkins University researchers suggests.The Hopkins group has also developed a simple blood test for this variation of the scavenger receptor class B type 1 gene ( SCARB1) but emphasized there is no approved therapy yet to address the problem in infertile women.Following up studies in female mice that first linked a deficiency in these receptors for HDL -- the so-called "good" or " healthy" cholesterol -- and infertility, researchers report finding the same link in studies of women with a history of infertility.The findings has been published on-line this week in the journal Human Reproduction.If the new study's findings hold up on further investigation, the John Hopkins team says they not only will offer clues into a genetic cause of some infertility, but could also lead to a treatment already shown to work in mice."Infertility is fairly common and a lot of the reasons for it are still unknown," warns endocrinologist Annabelle Rodriguez, an associate professor of medicine at the Johns Hopkins University School of Medicine and the lead author. "Right now, the benefit of this research is in knowing that there might be a genetic reason for why some women have difficulty getting pregnant. In the future, we hope this knowledge can be translated into a cure for this type of infertility."
