SAN FRANCISCO, June 1 (Xinhua) -- Microsoft on Wednesday gave a preview of its next-generation operating system code-named "Windows 8."The software giant introduced the successor to Windows 7 at the ninth edition of The Wall Street Journal's Digital: All Things Digital in Rancho Palos Verdes, California, some 48 km south of Los Angeles.With an interface quite different from legacy Windows, Windows 8 looks more like Windows Phone 7 and features an app management from Windows mobile operating system. It is the first major attempt by Microsoft to expand a mobile operating system to desktop status, and is expected to be touch-friendly and work seamlessly on desktops, laptops and tablet computers.For legacy Windows users, they need to swipe up from the bottom of the screen to get to the Windows 7-based view. Microsoft said the new system will be compatible with all Windows 7 logo PCs, software and peripherals.During the demonstration, Steven Sinofsky, Microsoft's head of Windows, also said the importance of not abandoning the established technologies from the traditional PC. "The mouse and the keyboard aren't evil. They're just tools. There are a number of applications that require the greater precision offered by the mouse." said Sinofsky.Sinofsky did not say when Windows 8 would be available.Although there are some tablets running Microsoft's current Windows 7 operating system, the software giant has been criticized for failing to adequately respond to the fast growth of tablet computers, like Apple's iPad.

MANILA, June 14 (Xinhua) -- At least 200 people, mostly children, have been taken to hospitals after allegedly suffering from food poisoning at a birthday party in the northern Philippine province of Bulacan, local newspaper Manila Bulletin reported Tuesday.Most of the victims suffered from stomach and chest pains, diarrhea and vomiting, local health officer Dr. Rizalli Lucas was quoted as saying.The victims claimed the cause of their food poisoning was the spaghetti served during a birthday celebration over the weekend in a village of Calumpit town.James P. de Jesus, mayor of Calumpit, said the situation is now contained and controlled but they still have to implement health measures and to determine the cause of the alleged food poisoning.Police have started investigating the incident.

BEIJING, June 12 (Xinhua) -- China's Supreme People's Court (SPC) on Sunday publicized a judicial interpretation which sets specific rules for the country's courts to order penalties to criminals sabotaging TV and radio facilities.The interpretation said that criminals, whose sabotage causes information block for disaster early warning, rescue and others concern public security, could be convicted three to seven years of imprisonment on the charge of sabotaging TV and radio broadcast facilities.Other circumstances that could be convicted the imprisonment include sabotage that causes malfunction in the broadcast of TV and radio stations, according to the new law.According to statistics with the SPC, there have been more than 5,000 cases of sabotaging cable TV wires and more than 1,000 cases of sabotaging state-owned fiber optic lines and other cases of stealing broadcast facilities since 2006 in China.

CANBERRA, Sept. 9 (Xinhua) -- Managing other people at work triggers structural changes in the brain, protecting its memory and learning center well into old age, Australia's study revealed on Friday.Australia's University of New South Wales (UNSW) researchers have, for the first time, identified a clear link between managerial experience throughout a person's working life, and the integrity and larger size of an individual's hippocampus (the area of the brain responsible for learning and memory) at the age of 80. "We found a clear relationship between the number of employees a person may have supervised or been responsible for and the size of the hippocampus," Dr Michael Valenzuela, Leader of Regenerative Neuroscience in UNSW's School of Psychiatry, said in a statement released on Friday."This could be linked to the unique mental demands of managing people, which requires continuous problem solving, short term memory and a lot of emotional intelligence, such as the ability to put yourself in another person's shoes. Over time this could translate into the structural brain changes we observed."The findings confirmed that staying mentally active promotes brain health, potentially warding off neurodegenerative diseases such as Alzheimer's.Using MRI imagery in a cohort of 75-92 year-olds, researchers found larger hippocampal volumes in those with managerial experience compared to those without. The effect was also seen in women who had taken on managerial roles in nursing or teaching, for example.The study was presented at this week's Brain Sciences UNSW symposium Brain Plasticity The Adaptable Brain, held in Australia.

WASHINGTON, July 13 (Xinhua) -- Human neural stem cells are capable of helping people regain learning and memory abilities lost due to radiation treatment for brain tumors, a University of California, Irvine (UCI) study suggests.Research with rats found that stem cells transplanted two days after cranial irradiation restored cognitive function, as measured in one- and four-month assessments. In contrast, irradiated rats not treated with stem cells showed no cognitive improvement."Our findings provide solid evidence that such cells can be used to reverse radiation-induced damage of healthy tissue in the brain," said Charles Limoli, a UCI radiation oncology professor.Study results will appear Friday in Cancer Research, a journal of the American Association for Cancer Research.Radiotherapy for brain tumors is limited by how well the surrounding tissue tolerates it. Patients receiving radiation at effective levels suffer varying degrees of learning and memory loss that can adversely affect their quality of life."In almost every instance, people experience severe cognitive impairment that's progressive and debilitating," Limoli said. " Pediatric cancer patients can experience a drop of up to three IQ points per year."For the UCI study, multipotent human neural stem cells were transplanted into the brains of rats that had undergone radiation treatment. They migrated throughout the hippocampus -- a region known for the growth of new neurons -- and developed into brain cells.Researchers assessed the rats one month and four months after transplantation, noting enhanced learning and memory abilities at both intervals.Additionally, they found that transplanting as few as 100,000 human neural stem cells was sufficient to improve cognition after cranial irradiation. Of cells surviving the process, about 15 percent turned into new neurons, while another 45 percent became astrocytes and oligodendrocytes -- cells that support cerebral neurons.Most notably, Limoli said, he and his colleagues discovered that about 11 percent of the engrafted cells expressed a behaviorally induced marker of learning, indicating the functional integration of those cells into memory circuits in the hippocampus."This research suggests that stem cell therapies may one day be implemented in the clinic to provide relief to patients suffering from cognitive impairments incurred as a result of their cancer treatments," Limoli said.
