BEIJING, Aug. 16 (Xinhuanet) -- It is widely accepted that obesity leads to an increased risk of health complications, but new studies quoted by media Tuesday challenge the conventional notion.“Our studies challenge the idea that all obese individuals need to lose weight,” said Dr. Jennifer Kuk, assistant professor in York University’s School of Kinesiology & Health Science in Toronto.  One of the studies used data from the Aerobics Center Longitudinal Study consisting of 29,533 individuals and assessed their mortality in 16 years.It found no difference in death risks between normal-weight individuals and obese ones. "Since the obese people did not have greater risk of dying than normal weight individuals, they don’t need to lose weight," said Dr. Kuk.But the finding did not give obese individuals a “free license” to gain weight, Dr. Kuk added. Maintaining weight, eating right and exercising may be better than trying to lose weight in the long run, said Dr. Kuk.

SINGAPORE, July 3 (Xinhua) -- The over 60 nursing homes in Singapore, especially those run by voluntary welfare organizations, are facing a bed crunch, local daily Straits Times reported on Sunday.The newspaper found in a check with 20 homes that more than half of the nursing homes were running at full or almost full capacity. Homes run by voluntary welfare organizations, where there are subsidized beds, have long waiting lists.The average waiting time for a bed in nursing homes run by voluntary welfare organizations rose from 50 days in 2008 to about 60 days early last year, the newspaper said.It is easier to get a bed in a privately run home, though only slightly and if you can afford it. Econ Healthcare Group, which runs eight nursing homes in Singapore, said the occupancy rate is 99 percent and it has waiting lists of up to 20 people at some branches.Demand for nursing homes in the city state can only grow given the aging population. By 2030, the number of people aged 65 or above is projected to reach 900,000, or one in every five residents.

SAN FRANCISCO, June 28 (Xinhua) -- Microsoft on Tuesday launched its cloud service Office 365, which was the software giant's answer to competing products from Google and other companies.The service includes on-line versions of Word, PowerPoint, Excel, Outlook and other Office applications, as well as Microsoft 's communication and collaboration tools such as Exchange, SharePoint and Lync.It will allow users to work on files and documents at the same time using instant messaging and video-conferencing."Where does Office meet the cloud? It's Office 365, the absolute best productivity and collaboration service for business around the world," Microsoft CEO Steve Ballmer said at a webcast event.Microsoft said that Office 365 is now available in 40 markets with choices for small and big businesses ranging from 2 to 27 U.S. dollars per user per month.Office 365 will compete directly with the web-based Google Apps, which Google sells for 50 dollars per user per year.Microsoft's service was introduced in beta last year and the company said response was enthusiastic with more than 200,000 organizations signed up and began testing it in a few months."With a few clicks, Office 365 levels the playing field, giving small and midsize businesses powerful collaboration tools that have given big businesses an edge for years," Ballmer said in a statement.

PARIS, Aug. 19 (Xinhua) -- Marine scientists and representatives from the private sector and military establishments would meet at UNESCO at the end of this month to measure noise's impact on marine life, the Paris-based UN scientific branch UNESCO said Friday.The main agenda of the meeting, which is due from Aug. 30 to Sep. 1, was to discuss the program of the International Quiet Ocean Experiment (IQOE)."This decade-long project aims to fill the considerable knowledge gaps in this area, so that management of ocean noise can be more informed and effective," UNESCO said in a statement.The Quiet Ocean Experiments was initiated against the background that human activities on the high seas have increased significantly in recent decades, and resulted in impact upon many marine species relying mainly on sound to communicate.However, some sounds are suspected to alter the behavior of marine animals. For example, several whale species have raised the volume of the squeaks, clicks and moans by which they communicate with each other.The experiment is organized by the Scientific Committee on Oceanic Research (SCOR) and the Partnership for Observation of the Global Oceans (POGO), of which UNESCO's Intergovernmental Oceanographic Commission (IOC) is a member.
