BEIJING, Sept. 2 (Xinhuanet) -- Insomnia costs average U.S. worker 11.3 days, or 2,280 dollars, in lost productivity each year, according to a new study published in journal Sleep.The total cost to the nation is 63.2 billion dollars annually, the study said.Researchers analyzed information about sleep habits and work performance from 7,428 workers taking part in Harvard Medical School's American Insomnia Study survey in 2008-09.As a result, 23.2 percent of the participants suffered insomnia, characterized by a hard time falling or staying asleep.Moreover, insomnia rates were 19.9 percent for those with less than a high school education and 21.5 percent for college graduates."We were shocked by the enormous impact insomnia has on the average person's life," said Ronald C. Kessler, a lead author and a psychiatric epidemiologist at Harvard Medical School."It's an underappreciated problem. Americans are not missing work because of insomnia. They are still going to their jobs but accomplishing less because they're tired," Kessler noted.Employers usually ignore the consequences of insomnia because it's not considered an illness resulting in workers' absenteeism.But the high cost of lost sleep identified in this study indicates that employers need to take it more seriously.

UNITED NATIONS, June 9 (Xinhua) -- The message delivered by scores of speakers on the second day of the three-day UN High Level Meeting on AIDS on Thursday, marking 30 years of the pandemic, was that most of their countries were making progress but increased efforts had to be made with greater cooperation needed among nations.In the case of developing states, gratitude was expressed for past help but more aid was needed to continue the battle.Despite the similarities in content, the chair, UN General Assembly President Joseph Deiss, repeatedly appealed to speakers to limit their speeches to their allotted five minutes, warning at the halfway point that if everyone was taking an extra few minutes, a fourth day would have to be added to the agenda.One of the briefest addresses, well under time, was delivered by Yin Li, China's vice health minister, which he referred to as " a responsible developing country."Briefly listing some of the steps taken, the Chinese vice minister focused on achieving the UNAIDS goal of the three Zs -- " Zero new HIV infections, zero discrimination and zero AIDS-related deaths.""We should unite to generate a joint force, irrespective of gender, skin color, nationality, beliefs, values and ideology. Developed countries should further provide developing countries with unselfish, unconditional financial and technical support," he said. "Developing countries should place AIDS control in a position as important as economic development and actively explore prevention and treatment mode consistent with national conditions. ""Second, given the increasing disease burden of AIDS," he said, "the private sector and relevant organizations should shoulder more social responsibility."On the one hand efforts should be made to mobilize more resources in AIDS to better implement prevention, treatment and care measures; on the other hand, multinational drug manufacturers should reduce by a large margin the price of drugs, testing equipment and reagents through technology transfer, contract manufacturing and reduction of monopoly profits in order to promote universal access to treatment services," Yin added.Since AIDS prevention and treatment in China is an important component in the global fight against AIDS, he said, "Progress made in China is a positive contribution globally."The High Level Meeting on AIDS is taking place 10 years after the UN Special Session on HIV/AIDS and five years since signing of the Political Declaration in which UN Member States committed to universal access to HIV prevention, treatment, care and support.Norway's minister of the environment and international development, Erik Solheim, said, "Prevention and treatment must be mutually reinforcing and better treatment regiments need to be made available."He called for development of innovative methods for prevention.While Solheim said "remarkable" results had been achieved in the last three decades, there still was a need for a " transformation of current working methods."AIDS must be taken out of isolation into an "integrated approach," noting that HIV response has to be connected with UN Secretary-General Ban Ki-moon's Global Strategy for Women's and Children's Health and "HIV and AIDS programs should be mainstreamed into national health systems, he said.Solheim said that the social, political and economic empowerment of women is crucial and he welcomed the establishment of the new UN agency UN Women."The burden of HIV in the world is reduced but major challenges remain," the minister said. "Our experience is that the approaches that work well on HIV, are those based on rights and on promoting the dignity of people."Celsius Waterberg, the health minister of Suriname, said the nation "is among the few countries in the Caribbean where the incidence of HIV infection has decreased by more than 25 percent."The strides forward are due to a national multi-sectoral HIV Council, setting up structures to provide leadership in quality of services and training in revised treatment protocols, he said.Suriname, the smallest sovereign state in South America, on the northeast coast of the continent, also introduced combined prevention tools and implemented pilot projects successful in mobilizing men for circumcision as an additional preventive measure, Waterberg said.Challenges that need to be overcome include harmful traditions and customs, misconceptions and adverse beliefs, language barriers in a multilingual society and vulnerability of small communities and individuals due to HIV-related stigma, gender inequalities and poverty, he said.Victor Makwenge Kaput, health minister of the Democratic Republic of Congo, said that although the government had made progress in supporting individuals living with HIV and protecting the uninfected, it continues to face many challenges. Indeed, HIV prevalence stood at 3.7 percent for pregnant women and 3 percent for the general population, he said.AIDS' victims increasingly are women and youth with infections particularly concentrated along the Congo River, the minister said. Today, 1.2 million citizens are infected. Total population in the third largest country in Africa, about the size of Western Europe, is 71 million.He said women account for roughly 71,000 new infections each year and the government is now paying particular attention to mother-to-child transmission.Kaput said his long war-torn nation is committed to the global vision of zero infections and appealed for support to curb the spread of HIV.

BEIJING, July 5 (Xinhuanet) -- A black iPhone 4 prototype has appeared for sale on eBay and the highest bidding hit one million U.S. dollars as of Monday, according to media reports.The listing is set to expire on July 11.The seller "jtmaxo" said, "I am a licensed cell phone repairman, this iPhone was bought from a person who really didn't know who he had."The seller later was frustrated to find that it was unable to be activated via iTunes.According to a check through Apple’s database, it is indeed listed as a prototype, and it has the tester code "DF1692" etched in the bottom right corner.Different from the iPhone 4 sold on markets, the handset lacks the + and - on the volume buttons, although the screen is fully functional.The price for the prototype will not remain as high as it is as the seller said that several "non-legitimate" bids have already been deleted.

BEIJING, Sept. 14 (Xinhuanet) -- Scientists had discovered the fossils of a new species of ancient carnivorous fish, National Geographic reported Monday.The newly-found ancient fish, "Laccognathus embryi", is a 1.8-meter-long predator, which was "waiting to lunge out to grab whatever was in front of it," said study co-author Ted Daeschler, a vertebrate zoologist at the Academy of Natural Sciences in Philadelphia, the U.S..It had a jaw filled with sharp teeth that were 1.5 inches long, the Journal of Vertebrate Paleontology described.The fish lived in the Devonian period, 415 to 360 million years ago, which "was a fish-eats-fish kind of world," Daeschler said. "There was a real arms race going. If you didn't have good armor on your body, you were very vulnerable.""It's not just finding the animal - it's also placing the animal in its evolutionary crucible," Daeschler added.Its closest living relative is the lungfish which can survive in the drought, scientists said.Scientists hope the finding can help in their study on the revolution of fishes as well as other species.

UNITED NATIONS, Sept. 19 (Xinhua) -- As the UN on Monday pursued the world's top killer -- non-communicable diseases (NCDs) -- a leading doctor from the World Health Organization (WHO) called for preventative measures on such chronic diseases to be placed higher on the international agenda."It's not a choice of dealing with it or not, it's an absolute fundamental imperative for development," said Dr. Douglas Bettcher, WHO's director for the Tobacco Free Initiative, told Xinhua in a recent telephone interview.With NCDs already claiming 36 million lives a year -- nearly 100,000 people a day -- the UN Geneva-based health agency, WHO warns that deaths from chronic diseases will continue to climb even faster, amounting to 52 million deaths by 2030.As world leaders on Monday kicked off a two-day high-level meeting to enact a roadmap to attack diseases like cancer, diabetes, heart and lung diseases, it is hoped that the summit on NCDs, which is being called a "once in a generation opportunity," moves to become a "worldwide priority," Bettcher said.Marking the second time in its history that the United Nations General Assembly has ever put a global disease on the table, health experts and world leaders from 193 nations met to avert what the UN has declared a "public health emergency in slow motion. ""It's a make it or break it time for moving forward this very important agenda at this time of global financial crisis," said Bettcher.Calling NCDs the top global killer "by a long shot," Bettcher attributed such rises in deaths partly to the aging of the world's population, rapid urbanization and increased exposure to risk factors, particularly in low-and middle-income countries."This is a landmark meeting," said UN Secretary-General Ban Ki- moon at the opening of the unprecedented meeting. "Three out of every five people on earth die from the diseases that we gather here to address."The last time the UN looked at a health issue under the global microscope on such a high-level was almost a decade ago.
