XI'AN, March 31 (Xinhua) -- Archeologists in the northwestern Shaanxi Province confirmed Thursday, after weeks of lab work, that the bones they found in a bronze cooking vessel from a 2,400-year-old tomb belonged to a male dog under a year old.Altogether 37 bones were found in the cooking vessel, which was unearthed in November 2010 from a tomb near the Xianyang International Airport in the suburbs of Xi'an, said Liu Daiyun, a researcher with the Shaanxi Provincial Archeological Institute."When we opened the 20-cm tall cooking vessel, we were shocked to find bones and soup inside," said Liu.The bones and soup had all turned greenish, similar in color to the bronze container, he said.Cooking vessels were a typical offering Chinese once presented to their deceased ancestors, said Liu.The custom became prevalent around the Warring States Period (475 - 221 BC), the time Liu and his colleagues believed this dog stew was offered.Hu Songmei, a researcher who did most of the lab work to identify the bones, said they found the bones were "strikingly similar" to four complete sets of canine skeletons preserved at the institute's lab.The newly found bones, however, were smaller, indicating the dog was just a pup, said Hu.Hu said further lab work was needed to tell the exact species of the canine. "Dogs were domesticated by humans at least 10,000 years ago, but the early dog species that evolved from wild wolves could be very different from today's pet dogs."Besides the dog bones, experts also found a wine-like liquid in another airtight kitchen ware from the same tomb. "Whoever the tomb owner was, he must have loved liquor and meat, so his sons wished he could still enjoy the feast in his grave."

BEIJING, March 24 (Xinhuanet) -- A new study has found that many overweight women and children often underestimate how heavy they are, according to media reports Wednesday.The study, conducted by researchers from Columbia University Medical Center in New York City, surveyed 111 women with the average age of 39 and 111 children aged between 7 and 13.Among the participants, about 66 percent of the women and 39 percent of the kids were overweight or obese.They were shown images of different body silhouettes representing a range of weights, including underweight, normal weight, overweight, obese and extremely obese.The research findings showed that 82 percent of obese women and 43 percent of overweight women underestimated their weight, while only 13 percent of normal weight women did so.As to the children group, about 86 percent overweight or obese kids low-balled their weight.Lead author Dr. Nicole Dumas said, "The implications of this is the overwhelming impact of obesity on children who are growing up in communities where obesity and overweight is the norm rather than the exception."  She added, "Strategies to overcome the obesity epidemic will need to address this barrier to weight loss."

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.

SEOUL, April 12 (Xinhua) -- South Korea has downgraded its alert level for foot-and-mouth disease (FMD) one notch as the disease has practically come to an end, the Ministry for Food, Agriculture, Forestry and Fisheries said Tuesday.The ministry said that it lowered the alert level from "orange" to "yellow," the second-lowest status in the four-tiered alert system, as no additional burial of livestock has occurred in three weeks after the last case in Hongseong, South Chungcheong Province, on March 21.The country dropped the alert level from the highest level of " red" to "orange" on March 24.The highly contagious animal disease, first confirmed on Nov. 29, has forced the country to cull more than 3.47 million livestock, mostly pigs and cattle, resulting in losses of 3 trillion won (2.6 billion U.S. dollars).The ministry, meanwhile, said that 670 animal quarantine experts will continue to decontaminate livestock farms once every week and keep close watch to see if any animals become sick.

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.
