WASHINGTON, Nov. 16 (Xinhua) -- Data from NASA's Galileo spacecraft have provided scientists evidence of what appears to be a body of liquid water, equal in volume to the North American Great Lakes, beneath the icy surface of Jupiter's moon, Europa, the U.S. space agency announced Wednesday.The data suggest there is significant exchange between Europa's icy shell and the ocean beneath. This information could bolster arguments that Europa's global subsurface ocean represents a potential habitat for life elsewhere in our solar system. The findings will be published Thursday in the scientific journal Nature.Europa, which is slightly smaller than Earth's moon, is believed to have a large ocean of salty water deep beneath its frozen crust. Galileo spacecraft, launched by the space shuttle Atlantis in 1989, studied Jupiter, which is the most massive planet in the solar system, and some of its many moons.Pictures of it sent back by Galileo point to a tortured surface of cracks and jumbled ice. Seeking to understand how such weird topography evolved in a place with such dim sunlight, scientists believe that the answer lies in similar processes on Earth.Their model suggests that Europa's ice shell is about 10 kilometers thick and within it are giant pockets of water, lying at depths as shallow as three kilometers. Warm water from these sub-surface lakes wells up in plumes, causing the ice to become brittle, crack and then collapse. The ice turnover would be a plus for the prospects for life, as it would transfer energy and nutrients between the sub-glacial lake and the surface."One opinion in the scientific community has been if the ice shell is thick, that's bad for biology. That might mean the surface isn't communicating with the underlying ocean," said Britney Schmidt, lead author of the paper and postdoctoral fellow at the Institute for Geophysics, University of Texas at Austin. " Now, we see evidence that it's a thick ice shell that can mix vigorously and new evidence for giant shallow lakes. That could make Europa and its ocean more habitable.""The data opens up some compelling possibilities," said Mary Voytek, director of NASA's Astrobiology Program. "However, scientists worldwide will want to take a close look at this analysis and review the data before we can fully appreciate the implication of these results."

BEIJING, Dec. 10 (Xinhua) -- Pharmaceutical producers will risk having their operation license revoked if they use prohibited chemicals as medicine ingredients or involved in fake drug production, China's drug regulator said in a circular Saturday.The State Food and Drug Administration said it would name and shame pharmaceutical companies if they make phoney medicine and withdraw the operation licenses of pharmacies if they intentionally sell unqualified drugs.The circular came in the wake of several counterfeit medicine scandals uncovered by Chinese police in the past few months.On Nov. 4, police seized more than 65 million imitation medicinal tablets and arrested 114 suspects in a cross-provincial raid on counterfeit drugs.In October, police raided on an illegal drug production and sale network and ended up with the seizure of 190 million yuan (29.9 million U.S. dollars) worth of counterfeit drugs.The suspects were found to have used starch or corn powder as ingredients for bogus medicine, or re-packaged expired pharmaceuticals.Police also found animal feed and chemical pigments in the counterfeit products.

WASHINGTON, Dec. 21 (Xinhua) -- New research suggests that, in people who don't currently have memory problems, those with smaller regions of the brain's cortex may be more likely to develop symptoms consistent with very early Alzheimer's disease.The study was published Wednesday in the online issue of Neurology, the medical journal of the American Academy of Neurology.For the study, researchers used brain scans to measure the thickness of regions of the brain's cortex in 159 people free of dementia with an average age of 76. The brain regions were chosen based on prior studies showing that they shrink in patients with Alzheimer's dementia.Of the 159 people, 19 were classified as at high risk for having early Alzheimer's disease due to smaller size of particular regions known to be vulnerable to Alzheimer's in the brain's cortex, 116 were classified as average risk and 24 as low risk. At the beginning of the study, participants were also given tests that measured memory, problem solving and ability to plan and pay attention. The tests will go on over the next three yearsThe study found that 21 percent of those at high risk experienced cognitive decline during three years of follow-up after the MRI scan, compared to seven percent of those at average risk and none of those at low risk."Further research is needed on how using MRI scans to measure the size of different brain regions in combination with other tests may help identify people at the greatest risk of developing early Alzheimer's as early as possible," said study author Bradford Dickerson, of Massachusetts General Hospital in Boston and a member of the American Academy of Neurology.

SAN FRANCISCO, Oct. 5 (Xinhua) -- Microsoft announced Wednesday that it will bring cable television content to its Xbox video game console over the upcoming holiday season, expanding the console into an entertainment hub.According to the company's press release, nearly 40 world- leading TV and entertainment providers such as HBO GO and BBC will stream their content through the Xbox Live service in more than 20 countries and regions.Users will be able to sift through shows online with the Kinect motion sensor device for Xbox 360 and Bing voice search, Microsoft said.To watch TV programs via Xbox as an alternate delivery system, customers have to already subscribe to the TV services and Microsoft's Xbox Live Gold service of 60 U.S. dollars per year."Today's announcement is a major step toward realizing our vision to bring you all the entertainment you want, shared with the people you care about, made easy," Microsoft said in the press release.Microsoft first entered the gaming console market in 2001 with the Xbox, the predecessor to the Xbox 360. The Xbox 360 currently competes with Sony's PlayStation 3 and Nintendo's Wii as the seventh generation of video game consoles.In June, Microsoft said 35 million people subscribed Xbox Live service around the world, spending an average of 60 hours a month playing games and watching movies and shows. Last year, the company integrated social networking features into Xbox Live, allowing users chat with each other while watching programs.

ACCRA, Dec. 1 (Xinhua) -- The Ghanaian government allayed the fears of many here on Thursday that it would provide funding for the treatment of persons living with HIV/AIDS in the country.Vice President John Dramani Mahama affirmed this when he addressed a ceremony to mark this year's World AIDS Day at Obuasi, near Kumasi, 270 km north of the capital Accra.Mahama said should the Global Fund pull out of supporting the country, the government would partner with development partners to raise the 5.8 million U. S. dollars needed yearly for the treatment of HIV/AIDS patients."Government will work together with the Ghana AIDS Commission (GAC) and donor partners to ensure that people living with HIV/ AIDS have access to antiretroviral drugs."The Presidency is with you, and whatever we will do to win the fight against HIV/AIDS shall be done," Mahama said.Ghana's HIV/AIDS infection rate, according to official figures, has dropped from 3 percent to the current 1.5 percent, albeit with pockets of higher rates of infection among some populations in the country.Mahama called for more innovativeness in mobilizing resources to avoid the danger of retrogression.Director-General of the GAC Angela El-Adas announced that the Ministry of Health had pledged 2.5 million Ghana cedis (1.66 million dollars) out of the 5.8 million dollars needed for next year.Meanwhile, in the capital, the Ghana Network of Persons Living with HIV and AIDS (NAP+ GHANA) joined persons living with HIV (PLHIV) globally on Thursday to commemorate this year's World AIDS Day."We stand united with our fellow PLHIV and the global HIV and AIDS community by fully supporting the vision of 'Getting to Zero', " Charity Owusu Danso, vice president of NAP+ Ghana, said in a message here.Established in 2005, NAP+GHANA is a network of member associations of persons living with HIV/AIDS in Ghana to represent the views, hopes and aspirations of PLHIV across the country."We are extremely worried. Everyday, we receive reports from PLHIV across the country that anti-retroviral drugs are out of stock or that hospitals or clinics won't give HIV treatment to new patients because there aren't even enough drugs for existing patients, " the statement said.
