SAN FRANCISCO, Nov. 3 (Xinhua) -- Hewlett-Packard Co. (HP) on Thursday introduced its Slate 2 Tablet PC, a business-targeted tablet computer running Windows operating system.Looking like the previous version, Slate 2, featuring an 8.9- inch screen, is upgraded with Intel Atom Z670 processor to deliver faster boot times and improved battery life up to six hours, said HP.It also has a Bluetooth keyboard dock and Swype keyboard which allows users to enter words by sliding a finger or stylus from letter to letter, lifting only between words.The device will be available to customers worldwide for 699 U.S. dollars later this month, according to HP.Slate 500, Slate 2's previous generation running Windows, was introduced last October and sold exclusively to businesses for 800 dollars upon launch.HP said in a statement that the Slate 2 tablet provides instant deployment for business and vertical markets such as education, healthcare, government and retail, where jobs frequently take users away from a traditional desk.The company on Thursday also announced HP 3115m, a new notebook PC targeting business, education and government customers. The notebook will be available in the Americas only next Friday with prices staring at 429 dollars.HP's consumer-oriented tablet TouchPad was killed off in August before former chief executive officer Leo Apotheker resigned. A dropped price from 499 to 99.99 dollars has made the unpopular device sold out in stores across the U.S. and Canada in days.Last Thursday, HP announced it will keep its PC business, saying it will build tablets running Microsoft's upcoming Windows 8 system in 2012.

SAN FRANCISCO, Nov. 3 (Xinhua)-- Amazon on Thursday launched an e-book lending service for owners of its Kindle devices, letting them borrow one digital book per month with no due date.Amazon said Kindle owners with an annual Prime membership can choose from thousands of books to borrow for free, including over 100 current and former New York Times Bestsellers. The online retail giant did not give an exact figure on the number of books of the new service.According to the company, readers' notes, highlights and bookmarks in borrowed books will be saved, so they will have them later if they purchase or re-borrow the book. Customers can have one book out at a time and the borrowed book should be returned through the Kindle device when they want to borrow a new one.In a press release, Amazon said it has reached agreement with publishers for a vast majority of titles for a fixed fee. But in some cases, Amazon is purchasing a title each time it is borrowed by a reader under standard wholesale terms.An Amazon Prime membership costs 79.99 U.S. dollars a year in the United States and gives members free two-day shipping and free access to the company's video streaming service containing some 13, 000 TV shows and movies.The new service is not compatible with smartphones, personal computers or tablet computers from other vendors running with Kindle apps, which makes Amazon's Kindle e-ink readers and its latest low-price tablet Kindle Fire more enticing to customers.According to Amazon, the Kindle Fire, which is priced at 199 U. S. dollars, will be released on Nov. 15.

BEIJING, Oct. 21 (Xinhua) -- China on Friday urged the European Union (EU) to recognize its full-market economy status at an early date and properly settle trade disputes amid the tumbling world economy."China hopes Belgium will exert its influence to push for an early recognizing of China's full-market economy status and remind the EU to be cautious on and restrain from using trade remedy measures," Vice Premier Wang Qishan told visiting Crown Prince Philippe of Belgium.Wang urged the 27-member bloc, also China's largest trade partner, to properly settle trade disputes with China during the talks at Diaoyutai State Guesthouse in downtown Beijing.Chinese Vice Premier Wang Qishan (R) shakes hands with Belgian Crown Prince Philippe in Beijing, capital of China, Oct. 21, 2011."China has contributed a lot to the world economy by recording a 9.4 percent growth in the first three quarters of this year while adjusting its economic structure and managing inflation expectations," Wang said.Prince Philippe, accompanied by a 450-member business delegation, is here to tap the Chinese market and seek investments from China, the world's top holder of foreign exchange reserves.During the 10-day trip, the delegation will visit the Chinese cities of Tianjin, Guangzhou, Shenzhen, Shanghai and Chongqing and is expected to sign about 40 contracts.Wang said China will expand two-way investment with Belgium, and enhance support to the two states' small and medium-sized enterprises via the China-Belgium direct equity investment fund.China-Belgium trade has continued to surge since the two states forged diplomatic ties in 1971, when the bilateral trade volume was only 20 million U.S. dollars, much less than the 22.1 billion U.S. dollar record in 2010."We could expand cooperation in two-way investment, trade, finance, chemical industry, environmental protection, logistics, and green economy," Wang said.

WASHINGTON, Nov. 9 (Xinhua) -- An international team of researchers funded by NASA and the National Science Foundation (NSF) will travel next month to one of Antarctica's most active, remote and harsh spots to determine how changes in the waters circulating under an active ice sheet are causing a glacier to accelerate and drain into the sea, the U.S. space agency announced Wednesday.The science expedition will be the most extensive ever deployed to Pine Island Glacier. It is the area of the ice-covered continent that concerns scientists most because of its potential to cause a rapid rise in sea level. Satellite measurements have shown this area is losing ice and surrounding glaciers are thinning, raising the possibility the ice could flow rapidly out to sea.The multidisciplinary group of 13 scientists, led by Robert Bindschadler, emeritus glaciologist of NASA's Goddard Space Flight Center, will depart from the McMurdo Station in Antarctica in mid- December and spend six weeks on the ice shelf. During their stay, they will use a combination of traditional tools and sophisticated new oceanographic instruments to measure the shape of the cavity underneath the ice shelf and determine how streams of warm ocean water enter it, move toward the very bottom of the glacier and melt its underbelly."The project aims to determine the underlying causes behind why Pine Island Glacier has begun to flow more rapidly and discharge more ice into the ocean," said Scott Borg, director of NSF's Division of Antarctic Sciences, the group that coordinates all U.S. research in Antarctica. "This could have a significant impact on global sea-level rise over the coming century."

WASHINGTON, Nov. 8 (Xinhua) -- Children with autism have more brain cells and heavier brains compared to typically developing children, according to a study to be published on Wednesday in the Journal of the American Medical Association.The small, preliminary study provides direct evidence for possible prenatal causes of autism.The prefrontal cortex is involved in various higher order functions such as language and communication, social behavior, mood, and attention. Children who have autism tend to show deficits in such functions.Eric Courchesne, of the University of San Diego School of Medicine Autism Center of Excellence, and colleagues conducted direct counts of brain cells in specific regions of the prefrontal cortex in postmortem brains of seven boys who had autism and six typically developing males, ranging in age from 2-16 years. Most participants had died in accidents, but the researchers did not base their selection on causes of death.The researchers found that children with autism had 67 percent more neurons in the prefrontal cortex and heavier brains for their age compared to typically developing children. Since these neurons are produced before birth, the study's findings suggest that faulty prenatal cell birth or maintenance may be involved in the development of autism. Another possible factor that may contribute to the neuronal excess is a reduction in apoptosis, or programmed cell death, which normally occurs during the third trimester and early postnatal life.Though small, this preliminary study examined all relevant postmortem tissue available at the time. The relative scarcity of tissue from very young children may limit future research as well, but efforts to include a larger number of samples are needed to confirm these findings and to identify patterns of age-related changes in autism, the researchers say."Earlier studies of head circumference and early brain overgrowth have pointed us in this direction, but there have been few quantitative neuroanatomical studies due to the lack of postmortem tissue from children with autism," said Thomas Insel, director of the National Institute of Mental Health, in a statement. "These new results, along with an earlier study reporting altered wiring of the prefrontal cortex, focus our attention on this critical area of the brain in autism."
