WASHINGTON, Nov. 14 (Xinhua) -- Nearly a fifth of all Americans 12 years or older have hearing loss so severe that it may make communication difficult, according to a new study led by Johns Hopkins University researchers and published Monday in the Archives of Internal Medicine.The findings, thought to be the first nationally representative estimate of hearing loss, suggest that many more people than previously thought are affected by this condition.Study leader Frank Lin, an assistant professor, and his colleagues used data from the National Health and Nutritional Examination Surveys (NHANES), a research program that has periodically gathered health data from thousands of Americans since 1971. The researchers analyzed data from all participants age 12 and over whose hearing was tested during NHANES examinations from 2001 to 2008. Unlike previous estimates, NHANES includes men and women of all races and ages, from cities scattered across the country, so it's thought to statistically mimic the population of the Untied States.Using the World Health Organization's definition for hearing loss (not being able to hear sounds of 25 decibels or less in the speech frequencies), the researchers found that overall, about 30 million Americans, or 12.7 percent of the population, had hearing loss in both ears. That number jumps to about 48 million, or 20.3 percent, for people who have hearing loss in at least one ear. These numbers far surpass previous estimates of 21 to 29 million.Hearing loss prevalence nearly doubled with every age decade, with women and blacks being significantly less likely to have hearing loss at any age. Lin and his colleagues aren't sure why these groups appear to be protected. However, he notes that the female hormone estrogen, as well as the melanin pigment in darker skin, could have a protective effect on the inner ear.

Hu Jintao held talks with Heinz Fischer in Vienna Monday.China is willing to import more goods from Austria and to work with Austria to seek cooperation with third countries in Central and Eastern Europe, said the Chinese president, who also asked Austria to create favorable conditions for Chinese investors in Austria.Meanwhile, Hu urged Vienna to play a more active role in pushing for the EU's recognition of China's full market economy status and for a lift of the bloc's restrictions on high-tech exports to China.In the culture sphere, the two sides should promote people-to-people exchanges and boost cooperation in culture, eduction and media among others, Hu said.In addition, the two countries should also deepen cooperation in multilateral mechanisms to jointly push for a more just and fairer international political and economic order, Hu said.China, he added, is willing to enhance cooperation and coordination with Austria on important issues such as global economic governance, climate change, energy security and peaceful settlement of international disputes.History has proven that as long as the two sides understand and support each other, and respect each other's social systems and development models, the bilateral relationship can achieve long-term, steady and healthy development, Hu said.Fischer, for his part, said that he fully agrees with Hu's proposal, adding that his country is willing to enhance cooperation with China in culture, science and technology and tourism and expand coordination in the United Nations and other multilateral frameworks.

BEIJING, Nov. 7 (Xinhuanet) -- A huge asteroid will pass closer to Earth than the moon on Tuesday, but experts say there is no cause for alarm.Asteroid 2005 YU 55 will pass about 300-thousand kilometers from the earth. The giant space rock is about 400 meters in diameter. The close encounter will occur at 23:28 Greenwich Mean Time. Computer models showing the asteroid’s path for the next 100 years show there is no chance it will hit Earth during that time.Previous studies show the asteroid is what is called a C-type asteroid that is likely made of carbon-based materials and some silicate rock.

SANTO DOMINGO, Sept. 30 (Xinhua) -- Haitian health authorities on Friday said the number of deaths caused by cholera increased to 6,435 in the Caribbean country since October 2010.The Haitian Health Ministry said the number of people infected with cholera almost reached half a million, although the ministry repeated the epidemic was decreasing.The report said 455,727 people had been treated due to cholera, and 242,205 had to be hospitalized.The western province of Artibonite suffered the plague most with 1,196 deaths. The southwest province of Nippes registered the smallest death toll of 181.Meanwhile, in the Haitian capital Port-au-Prince, 221 people have been killed since October 2010 when the epidemic first broke out in central Haiti.The epidemic is supposedly due to the spill of dregs from a Nepalese camp, which is part of the UN Stabilization Mission in Haiti (MINUSTAH).The Dominican Republic, a country neighboring the island country Haiti to the east, has also been suffering the disease since November 2010, which has killed at least 135 people there.
