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."

ISLAMABAD, Nov. 14 (Xinhua) -- Pakistan ranks the seventh in the world in terms of diabetes prevalence rate and over 7.1 million people in the country are diabetes patients, reported local media on Monday.Quoting a report by the World International Diabetes Federation, a local English newspaper "The News" said that every year 89,000 people die of diabetes in Pakistan and the number of diabetes patients in the country could hit 11.5 million by the year 2025 if proper measures were not taken.This would make Pakistan the world's fifth largest country in terms of its number of diabetes patients 14 years later, warned the report.At a seminar organized Monday in Islamabad to observe the World Diabetes Day which falls on Nov. 14, Dr. Abdus Salam from Shifa International Hospital, a private-run hospital in the capital city, said that every ten seconds, two people are diagnosed with diabetes and one person dies of diabetes-related causes.The average age of diabetes patients in Pakistan is one of the lowest in the world, said the report. In a bid to raise public awareness about the harmful effects of diabetes, various diabetes camps, scientific sessions, seminars and walks were organized across the country on Monday to mark the World Diabetes Day.In a message delivered on Sunday, Pakistani Prime Minister Yusuf Raza Gilani said that the World Diabetes Day draws attention to the lethality of the disease and underscores the need of preventive measures at individual and collective levels."Diabetes is a killer which is taking the life of one person out of every 800," said the prime minister, adding that "this disease hits people of all age groups, rich and poor alike without any discrimination."

SAN FRANCISCO, Oct. 27 (Xinhua) -- Hewlett-Packard(HP) on Thursday announced that it will keep its personal systems group ( PSG) and continue to sell personal computers."HP objectively evaluated the strategic, financial and operational impact of spinning off PSG. It's clear after our analysis that keeping PSG within HP is right for customers and partners, right for shareholders, and right for employees," Meg Whitman, HP president and chief executive officer, said in a statement.On Aug. 18, former CEO Leo Apotheker said HP was considering spin off the PC business, which drove shares of the company to plunge 20 percent the following day.HP then said its board of directors has authorized the exploration of strategic alternatives for the PSG, and it will consider a broad range of options that may include a full or partial separation of the PC business through a spin-off or other transaction.According to HP, the review so far revealed the depth of the integration of its PC division that has occurred across the company's key operations including supply chain and procurement.In addition, it indicated that the division has made significant contributions to HP's solutions portfolio and overall brand value."Finally, it also showed that the cost to recreate these in a standalone company outweighed any benefits of separation," HP said in a press release announcing the latest decision.HP is now the world's largest PC-maker with revenues of the PC division totaling 40.7 billion U.S. dollars for fiscal year 2010, according to figures from the company.A recent report from market research firm Gartner found that in the third quarter of 2011, HP's PC shipments grew 5.3 percent year- on-year, faster than the industry average of 3.2 percent, and its share in global PC market actually increased slightly to 17.7 percent.Though the PC division has a lower margin, the position and scale as the world's No. 1 PC-vendor gives HP advantage to negotiate with other suppliers and helps its other businesses, analysts said.The announcement to keep the PC unit is seen as the first major move of HP under new CEO Whitman, who took the job just over a month ago after replacing Apotheker on Sept. 22.

  

SAN FRANCISCO, Jan. 12 (Xinhua) -- Microsoft on Thursday announced a patent licensing agreement with LG Electronics covering the South Korean manufacturer's tablets, smartphones and other consumer devices running Google's Android or Chrome operating system.In a press release, Microsoft said it marks the 11th deal with a device manufacturer leveraging Google's operating system platform, noting that "more than 70 percent of all Android smartphones in the U.S. are now receiving coverage under Microsoft 's patent portfolio."Terms of the deal were not disclosed. So far, Microsoft has struck major cross-licensing patent agreements with HTC, Samsung and Acer, among others.Last September, Microsoft announced a broad patent deal with Samsung. U.S. media reports cited South Korean media as saying that Microsoft had wanted Samsung to pay 10 to 15 U.S. dollars for each Android device.The booming mobile market has been harassed by acrimonious legal battles over patent infringement. Being an open source operating system, Google's Android has become a major target of patent suits.Microsoft has been going after companies that make phones and tablets running Android, rather than directly against Google. But the two tech giants are still engaged in public spats over the issue after Google's top legal officer posted a scathing blog last August accusing Microsoft and other companies of waging "a hostile, organized campaign against Android."Motorola Mobility, which Google announced to acquire in a 12.5 billion-dollar deal last August, currently is the last major Android device vendor that refuses to take a license from Microsoft.Frank Shaw, Microsoft's head of communications, used Twitter to taunt Google on Thursday, twitting "Hey Google -- we are the 70 percent" with a link to their press release.Brad Smith, Microsoft's executive vice president and general counsel, also tweeted "it's time to recognize that in patent world, lawsuits are the 1 percent; license agreements are the 99 percent. "Google so far has made no comments on the Microsoft-LG patent deal.
