VIENNA, Sept. 22 (Xinhua) -- Climate change and rising temperature in the long term can lead to water shortages in the Alps region, international experts warned Thursday at the Water-Scarce Final Conference in the Austrian eastern city Graz.The Alpine region originally is rich in water resources due to a large number of glaciers, spring and abundant rainfall either in summer or winter. But global warming may change this situation which has been shown in the past years that the water reserve has reduced gradually due to climate change, warned the experts.Observation data have shown a significant decrease of 25 percent in groundwater recharge in the past 100 years which has also resulted in the reduction of mountain spring.Director of the Provincial Department of Water Resources of Styria Johann Wiedner point out, in 2003, droughts occurred in the eastern part of the Alps, including the state of Styria and water shortages were also found in other regions of the Alps. He said the phenomenon was giving a warning that people "have to do something."To this end, the European Union begun a project called "Alp Water Scarce" three years ago to observe water reserves, air temperature, water temperature and water table in this region and study the relationships among them.Wiedner also admitted that there is no shortage of water at least in the short term and water supply for the local residents is totally insured.

SAN FRANCISCO, June 9 (Xinhua) -- Hewlett-Packard Co. (HP) on Thursday announced that its tablet computer, HP TouchPad, will go on sale in the United States on July 1.Two versions of HP TouchPad, with the option of either 16 gigabytes or 32 gigabytes of internal storage, and both only with Wi-Fi connection, will be available in the United States for 499. 99 U.S. dollars and 599.99 dollars respectively, the company said in a statement.The product will hit stores in Britain, Ireland, France and Germany a few days later and in Canada in mid-July, with availability scheduled to follow later this year in Italy, Spain, Australia, China's Hong Kong, New Zealand and Singapore.Preorders in North America and Europe will begin on June 19, HP said.HP did not release the price details when it introduced TouchPad on Feb. 9. The black device, with a 9.7-inch touch screen, runs webOS operating system, a mobile platform developed by Palm, a smartphone maker acquired by HP last April for 1.8 billion dollars.

BEIJING, August 4 (Xinhuanet) -- Medtronic Inc. is giving Yale University a 2.5 million U.S. dollar grant to review the safety and effectiveness of its controversial spine treatment called Infuse Bone Graft, according to The Wall Street Journals Thursday.Under terms of the pact, the company will release to Yale and eventually the public what participants described as an unprecedented amount of clinical trial and other data. The university will select two research teams from other organizations to perform separate analyses of the data.The announcement comes in the wake of a paper in June in the Spine Journal. The paper revealed that several clinical studies of Infuse, conducted by surgeons with strong economic ties to Medtronic, failed to report serious complications that arose in the trials. The critical paper also found that many of the studies were designed in ways in favor of Infuse over a treatment given to a control group.Medtronic disputes some of the findings and is conducting an internal investigation of the matter.Infuse accounts for about 700 million dollars in annual sales for Medtronic. The product is under investigation by the Senate Finance Committee over the role payments to physicians who may have played how studies were reported.

SAN FRANCISCO, July 14 (Xinhua) -- Microsoft on Thursday introduces a hacking alert system to its Windows Live Hotmail email service alongside banning common passwords."When someone's account gets hijacked, their friends often find out before they do, because the hijacker uses their account to send spam or phishing email to all their contacts," said Microsoft in a blog post.The new security feature adds a "My friend's been hacked!" option in the "mark as" menu in Hotmail and also enables users to report hacked accounts via the junk mail filing screen.Then an alert will be sent to Microsoft, which will "make sure the account can no longer be used by spammers and activates an account recovery process to allow the owner to take back control the accounts."Users can report any email account as compromised and Hotmail will provide the information to other email providers like Yahoo! and Gmail, said the blog.Meanwhile, Microsoft said Hotmail will roll out a feature to prevent users from choosing commonly used and weak passwords, such as "123456," "ilovecats" and "gogiants." Users who currently use a weak password will be asked to change to a stronger one in the future.Hotmail, first launched in July 1996, is one of the first free email providers, and was acquired by Microsoft in 1997 for an estimated 400 million U.S. dollars.According to statistics released by comScore last August, Hotmail was then the world's largest web-based email service with around 364 million users, followed by Yahoo! Mail (280 million) and Gmail (191 million).

VIENNA, Aug. 11 (Xinhua) -- Austrian researchers have developed a method of using fungi and produced enzymes to split Polyethylene Terephthalate (PET) material into their initial state, enabling the recovery of all individual components, said the Austrian Center of Industrial Biotechnology (ACIB) Thursday in a press release.Enzyme is a special protein that acts as biological catalyst, for example, bacteria and fungi in the nature can break down long chain molecules.Researchers from the Technical University of Graz, the Technical University of Vienna and the Agricultural University of Vienna jointly found that efficient enzymes are capable to break and split PET into small fragments.With different methods, the researchers forced the fungi to overproduce their precious "split-tools" after they are modified and improved by genetic engineering.Through the new method developed by the ACIB, it is now possible to decompose the PET polymer to its initial monomers with high product quality and from this to produce new high-quality materials again.This circuit avoids waste and thus saves resources and is friendly to the environment, said Geog Guebitz, head of the Research Department on Enzymes and Polymers in the ACIB.He further explained that the ACIB has established a partnership with some industrial enterprises to carry out application experiments. From the current splitting time of 24 hours, the researchers expect to shorten the whole process to "a few hours," he added.PET is a common plastic material in the polyester family, widely used in the textile industry. PET film is mainly used in electrical insulation materials, which can be also used for production of film, X-ray films and computer taps, even to produce plastic bottle and other blow molding products.
