NEW YORK, March 29 (Xinhua) -- New York Attorney General Eric Schneiderman announced on Tuesday that his office will undertake a thorough review of AT&T's acquisition of T-Mobile for potential anti-competitive impacts on consumers and businesses.Schneiderman stressed that his review will weigh the benefits of the merger to New Yorkers, such as expanding the coverage of AT& T's next generation broadband wireless network to rural areas in upstate New York, against the anti-competitive risks posed to them."Cell phones are no longer a luxury for a few among us, but a basic necessity. The last thing New Yorkers need during these difficult economic times is to see cell phone prices rise," said Schneiderman in a statement. "We want to ensure all New Yorkers benefit from these important innovations that improve lives."AT&T's proposed 39-billion-U.S.-dollar purchase of T-Mobile would create the nation's largest wireless company with a total of 130 million subscribers nationwide, opening the door to a near duopoly shared by the merged firm and Verizon, according to the New York Attorney General's office.T-Mobile, a subsidiary of Deutsche Telekom, is a low-cost provider of choice for millions of New Yorkers and currently has 34 million customers nationwide, making it the fourth-largest wireless company in the United States.

WASHINGTON, April 20 (Xinhua) -- Those childhood music lessons could pay off decades later -- even for those who no longer play an instrument -- by keeping the mind sharper as people age, according to a preliminary study published by the American Psychological Association (APA).The study recruited 70 healthy adults age 60 to 83 who were divided into groups based on their levels of musical experience. The musicians performed better on several cognitive tests than individuals who had never studied an instrument or learned how to read music, according to the research findings published Wednesday online in the APA journal Neuropsychology."Musical activity throughout life may serve as a challenging cognitive exercise, making your brain fitter and more capable of accommodating the challenges of aging," said lead researcher Brenda Hanna-Pladdy, a clinical neuropsychologist at the University of Kansas Medical Center. "Since studying an instrument requires years of practice and learning, it may create alternate connections in the brain that could compensate for cognitive declines as we get older."The three groups of study participants included individuals with no musical training; with one to nine years of musical study; or with at least 10 years of musical training. All of the participants had similar levels of education and fitness and didn' t show any evidence of Alzheimer's disease.All of the musicians were amateurs who began playing an instrument at about 10 years of age. More than half played the piano while approximately a quarter had studied woodwind instruments such as the flute or clarinet. Smaller numbers performed with stringed instruments, percussion or brass instruments.The high-level musicians who had studied the longest performed the best on the cognitive tests, followed by the low-level musicians and non-musicians, revealing a trend relating to years of musical practice. The high-level musicians had statistically significant higher scores than the non-musicians on cognitive tests relating to visuospatial memory, naming objects and cognitive flexibility, or the brain's ability to adapt to new information.The brain functions measured by the tests typically decline as the body ages and more dramatically deteriorate in neurodegenerative conditions such as Alzheimer's disease. The results "suggest a strong predictive effect of high musical activity throughout the lifespan on preserved cognitive functioning in advanced age," the study stated.Half of the high-level musicians still played an instrument at the time of the study, but they didn't perform better on the cognitive tests than the other advanced musicians who had stopped playing years earlier. This suggests that the duration of musical study was more important than whether musicians continued playing at an advanced age, Hanna-Pladdy says."Based on previous research and our study results, we believe that both the years of musical participation and the age of acquisition are critical," Hanna-Pladdy says. "There are crucial periods in brain plasticity that enhance learning, which may make it easier to learn a musical instrument before a certain age and thus may have a larger impact on brain development."The preliminary study was correlational, meaning that the higher cognitive performance of the musicians couldn't be conclusively linked to their years of musical study. More research is needed to explore that possible link.

HAIKOU, Jan. 28 (Xinhua) -- China's aviation authorities on Friday started to allow helicopters to fly in low-altitude airspace over the tourist island of Hainan on a trial basis for the first time. The aim is to eventually open a part of the country's tightly-controlled airspace to private aircraft.Four helicopters were manned by eight pilots from Shanghai-based Zhengyang Investment Group, a leading domestic firm in the general aviation industry. They are expected to conduct test flights in the sky, 1,000 meters above the ground in Hainan in the next two months.The flight test will collect data for low-altitude flying and test the ground control system's response to emergencies, said Zou Jianming, chairman of Zhengyang Investment Group.Hainan is the first place in China to conduct test flights of private aircraft in low-altitude airspace, said Jiang Sixian, deputy governor of the province. Domestic and foreign firms are both welcome to invest in Hainan's general aviation sector to develop world-class tourism here.China's low-altitude airspace is controlled by the Air Force and the Civil Aviation Administration of China (CAAC). Every private aircraft flight needs approval, and the procedure can take from one day up to a week.But last November, the State Council and the Central Military Commission said that part of the low-altitude airspace would be opened to promote the country's general aviation sector, including the purchase and use of private planes.General aviation refers to the part of the aviation industry that excludes flights for military, law enforcement and public transport. China has only 900 aircraft, 80 airports and fewer than 10,000 pilots in the general aviation segment.The market for general aviation in China is valued at only 13 billion yuan (1.98 billion U.S. dollars) but is expected to grow by 15 percent annually until 2020, Hainan aviation officials said.

  

SAN FRANCISCO, May 10 (Xinhua) -- Microsoft Corp. on Monday said it will buy Internet communications company Skype for 8.5 billion U.S. dollars in cash, a bold move for the software giant to explore new business opportunities."Skype is a phenomenal service that is loved by millions of people around the world," Microsoft CEO Steve Ballmer said in a statement."Together we will create the future of real-time communications so people can easily stay connected to family, friends, clients and colleagues anywhere in the world," he added.Microsoft said it has agreed to buy Skype from the investor group led by Silver Lake, and the deal has been approved by the boards of directors of both companies.Skype will become a new business division within Microsoft, and Skype CEO Tony Bates will assume the title of president of the Microsoft Skype Division, reporting directly to Ballmer.The Skype deal ranks one of the biggest purchase in the 36-year history of Microsoft, which is struggling to compete in the fields of Internet and mobile phones beyond its dominance on personal computer software market.Founded in 2003 and based in Luxembourg, Skype offers a software application that allows users to make free or cheap phone calls and chats over the Internet with additional features including instant messaging and video conferencing.Numbers showed that Skype's 170 million connected users made over 207 billion minutes of voice and video conversations in 2010.Skype was acquired by eBay in September 2005, and then acquired by an investment group led by Silver Lake in November 2009.In a press release announcing the acquisition, Microsoft noted that the deal will increase the accessibility of real-time video and voice communications, generating significant new business and revenue opportunities, and enhancing its existing offerings of real-time communications products and services.Microsoft said Skype will support its devices like Xbox and Kinect, Windows Phone and a wide array of Windows devices, and it will continue to invest in and support Skype clients on non-Microsoft platforms.The acquisition is expected to obtain all required regulatory clearances within this calendar year, Microsoft said.

  

BEIJING, Feb. 15 (Xinhua) -- China's health authorities Tuesday vowed to improve their response to food safety incidents.The ministry would issue a protocol "as early as possible" on how to respond to and investigate food safety incidents, said Vice Health Minister Chen Xiaohong at a national meeting on food safety in Beijing.It would also provide better training for officials and professionals working in the field, Chen said.Last year, the ministry initiated investigations into several incidents such as milk powder that allegedly caused infant girls to grow breasts and illegal soup additives by restaurants.In the milk powder case, the investigation found no evidence that Synutra International's products had caused the problem. Media reports said the company was the victim of dirty tricks by a rival firm.In addition, the ministry blacklisted 48 substances illegally added to food and 22 misused food additives last year.The ministry would include projects related to food safety in state-sponsored health programs giving free medical services to the public in next five years, Health Minister Chen Zhu said at the same meeting.But Chen did not give details about what kind of projects they will be.Under the current six state health programs, the government provides free cataract surgery for the needy, free breast and cervical examinations for rural women, free hepatitis B vaccines, free folic acid pills for rural women, new cooking stoves in rural homes to prevent fluorine poisoning caused by coal stoves as well as modern toilets for rural residents.
