HELSINKI, July 4 (Xinhua) -- A new Finnish research shows that sleeplessness may be hereditary, and insomniacs are more likely to die earlier than people with healthy sleep patterns.The research is the first to link insomnia with mortality risk, Finnish media reported on Monday.The research is conducted by the Institute of Occupational Health in collaboration with the University of Helsinki and the Finnish National Institute for Health and WelfareIn a large-scale twin study, the Finnish researchers followed the health status of 12,500 adult twin pairs during the years from 1990 to 2009. Twenty percent of the participants were suffering from sleeplessness symptoms, including difficulty in initiating sleep, nocturnal awakening and non-restorative sleep.The study found out that compared with unidentical twins, identical twins were more likely to suffer from similar insomnia symptoms. This finding indicates that genetic factors play a role in the formation of insomnia.Moreover, the participants were divided into three groups, according to their sleep qualities. Out of the participants, 48 percent were good sleepers, 40 percent average sleepers and 12 percent poor sleepers. The search result shows that insomnia-related symptoms may increase mortality risk.In addition, compared with good sleepers, 7 percent of the women and 22 percent of the men who were average sleepers were more likely to die earlier; and poor sleepers were 1.5 times more likely to die earlier.According to the researchers, sleeplessness is a common health problem among working-age cohort. Chronic sleeplessness raises the risk of many illnesses and accidents, and thus weakens people's quality of life and ability to operate properly.The experts suggest that insomniacs should seek medical treatment in time, and chronic insomnia patients should be better treated with non-drug therapy.

WASHINGTON, Sept. 27 (Xinhua) -- Debris from NASA's decommissioned Upper Atmosphere Research Satellite (UARS) that crashed to Earth on Saturday fell harmlessly in a remote area of the South Pacific Ocean, NASA said on Tuesday.According to the space agency, the Joint Space Operations Center at Vandenberg Air Force Base in California has determined the satellite entered the atmosphere over the Pacific Ocean at 14.1 degrees south latitude and 170.2 west longitude at midnight EDT Saturday. The debris field is located between 300 miles and 800 miles downrange, or generally northeast of the re-entry point."This location is over a broad, remote ocean area in the Southern Hemisphere, far from any major land mass," NASA announced, adding that it is "not aware of any possible debris sightings from this geographic area."NASA scientists estimated a 1-in-3,200 chance a satellite part could hit someone on earth. Therefore, any individual's odds of being struck are about one in 21 trillion.The UARS satellite, launched in 1991 from a space shuttle, was the first multi-instrumented satellite to observe numerous chemical constituents of the atmosphere with a goal of better understanding atmospheric photochemistry and transport.

YANGON, July 10 (Xinhua) -- Myanmar is projecting to build the first-ever liver transplant hospital in line with the international standard, the local weekly Voice reported Sunday.With the technological help of the Changi General Hospital of Singapore, a 40-million-U.S dollar worth private hospital has started building since late last month.The hospital will offer services for the patients living with heart and kidney diseases and for protection from being affected Methicillin-Resistant Staphylococcus Aureus (MRSA), the report said.In Myanmar, liver transplant will cost about 20 million Kyats ( 25,000 U.S. dollars), lesser than other countries, the report added.Myanmar experts carried out successful liver-transplant operation in 2004 for the first time and in 2009 for the second time.

SAN FRANCISCO, June 15 (Xinhua) -- As social networking sites like Facebook and Twitter grow worldwide, more Internet retailers are beefing up their efforts to add social twists to their business, trying to define the idea of "social commerce" and capitalize the opportunity.On Wednesday, online auction giant eBay revealed some of the social features it is planning to launch later this year, while Copious, a San Francisco-based startup, launched its online social commerce marketplace with a slogan of "buying from and selling to people, not strangers."Copious asks users to log in through their Facebook accounts and allows buyers and sellers to see if they have friends in common in their social networking sites. Buyers can see more information about a seller and also see whether anyone in their networks has purchased, shared or commented on an item from a specific seller, rather than anonymity or simple profiles on sites like eBay and Craigslist.As for sellers, Copious has a social pricing mechanism that enables a seller to offer buyers discounts for sharing listings on Facebook and for following the seller on Copious.Jonathan Ehrlich, Copious co-founder and former Facebook head of marketing, told technology blog TechCrunch that the site is centralized around using social data as a signal to help users understand and trust other parties.According to Copious, the startup founded in January 2011 has raised two million U.S. dollars in funding from Foundation Capital, Google Ventures, Blackberry Partners Fund and a number of Silicon Valley angel investors.Also on Wednesday, Christopher Payne, vice president and head of eBay North America, delivered a keynote speech at the Internet Retailer Conference and Exhibition 2011 in San Diego, revealing some features eBay is launching during the social trend.One feature will enable users to log in their Facebook account on eBay's homepage to get product recommendations based on one's purchasing history and things they have "liked" on their Facebook page. Another feature will allow users to post multiple products on their Facebook page to get their friends' opinions and ask them to vote for the final purchase.EBay has been stepping up its social efforts, and Payne said on Wednesday that social is a top-level initiative for Internet retailers. Last month, eBay hired former Yahoo executive Don Bradford to lead its social commerce efforts. Last November, it launched Group Gifts service, enabling users to chip in to buy a gift for someone.A research by Adgregate Market in March showed that more brand websites are losing traffic to their Facebook pages. The study revealed that the "Facebook stores" of most Internet retailers are more efficient at acquiring visitors, indicating social commerce is poised to take off.Although the idea of social commerce is still new, more companies are trying to seize the opportunity in their own moves.There are many other companies taking the social commerce model. Oodle, the exclusive provider of classified ads on the Facebook Marketplace, rolled out a series of social features last December to make more money from social classifieds.In February, Payvment Inc. launched a Facebook Mall, where consumers can shop for more than 1.2 million products among 60,000 retailers in a single shopping cart.Yardsellr, which is often called "an eBay for Facebook," allows sellers to list items at fixed prices in different categories called "blocks," such as jewelry and purses. Prospective buyers can "like" the "blocks" they are interested in on the Yardsellr website or its Facebook page, and then they will get Facebook news feed if a seller has something to offer in the category.Yardsellr said 1.5 million people were following its "blocks" by late December 2010 and the number of new followers is growing by 20,000 daily.
