JERUSALEM, July 25 (Xinhua) -- A new study carried out by a Tel Aviv University researcher indicates that the common backache may not only be caused by bad positions or aging, but also by your genes.Prof. Gregory Livshits of the Sackler Faculty of Medicine says that genes play a major role in back pain, especially in the lower back, and in spinal deterioration.In a decade-long project with 2,500 identical and non-identical twins, Livshits found that, in one Arab family, the same back problems appeared in all the members of the family, whether young or old.According to the study, non-identical twins were three times more likely to have back pain, while identical twins were six times more likely to have the same back problems.Livshits believes the discovery of the link between back pains and genes could lead to much better treatment.The research was developed in collaboration with a team of scientists at Kings College, London, led by Prof. Tim Spector and Dr. Fran Williams and was recently published in the journal " Annals of the Rheumatic Diseases."In order to better investigate the genetic causes for one of the world most common pains, Livshits and his colleagues hope to put together an international consortium of research groups.

LOS ANGELES, June 7 (Xinhua) -- Salmonella, not E. coli, poses the greatest health threat to Americans, the U.S. Centers for Disease Control and Prevention (CDC) announced on Tuesday.Salmonella infections have risen 10 percent over the past 15 years, while several types of foodborne illness have been falling, the agency said in a report.Infections from Shiga toxin-producing E. coli O157 (the strain of most concern in the United States) have dropped almost in half and the rates of six other foodborne infections have been cut 23 percent, the CDC said.The agency issued the report as a deadly new strain of E.coli is spreading in several European countries."There are about 50 million people each year who become sick from food in the U.S.. That's about one in six Americans," CDC director Dr. Thomas R. Frieden said.The CDC attributed the reduction in infections from E. coli O157 to better detection and investigation of outbreaks, cleaner slaughterhouse methods, better testing of ground beef for E. coli, improved inspections of ground beef processing plants, regulations prohibiting E. coli O157 in ground beef and increased awareness of the importance of properly cooking beef.Other foodborne illnesses that fell in incidence over the same time period include those caused by the campylobacter, listeria, vibrio and yersinia pathogens.To reduce their risk of foodborne illness, people should assume that raw chicken and other meat have bacteria that can make you sick, the CDC said.In the kitchen, raw meats should not allow to contaminate counter tops or cutting boards and should be kept away from other foods, such as fruits and vegetables, the CDC advised.The agency also called on people to thoroughly cook meat, poultry, eggs and shellfish, while refraining from consuming unpasteurized milk, juice or soft cheese.

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.

LOS ANGELES, June 9 (Xinhua) -- The edge of our solar system may not be smooth, but filled with a turbulent sea of magnetic bubbles approximately 100 million miles (160 million kilometers) wide, NASA's Jet Propulsion Laboratory (JPL) said on Thursday.The finding was based on observations from NASA's Voyager spacecraft, humanity's farthest deep space sentinels, said JPL in Pasadena, Los Angeles.While using a new computer model to analyze Voyager data, scientists found the sun's distant magnetic field is made up of bubbles which are created when magnetic field lines reorganize, said JPL.The new model suggests the field lines are broken up into self- contained structures disconnected from the solar magnetic field, according to JPL."The sun's magnetic field extends all the way to the edge of the solar system," said astronomer Merav Opher of Boston University. "Because the sun spins, its magnetic field becomes twisted and wrinkled, a bit like a ballerina's skirt. Far, far away from the sun, where the Voyagers are, the folds of the skirt bunch up."Like Earth, our sun has a magnetic field with a north pole and a south pole. The field lines are stretched outward by the solar wind, a stream of charged particles emanating from the star that interacts with material expelled from others in our corner of the Milky Way galaxy.Understanding the structure of the sun's magnetic field will allow scientists to explain how galactic cosmic rays enter our solar system and help define how the star interacts with the rest of the galaxy.The Voyager spacecraft, more than nine billion miles (14 billion kilometers) away from Earth, are traveling in a boundary region. In that area, the solar wind and magnetic field are affected by material expelled from other stars in our corner of the Milky Way galaxy.Launched in 1977, the Voyager twin spacecraft have been on a 33- year journey. They are en route to reach the edge of interstellar space. JPL built the spacecraft and continues to operate them.

BEIJING, Sept. 11 (Xinhua) -- Despite a series of disasters, Chinese people tend to believe that the moon is still round and bright in the Mid-autumn Festival.Falling on Monday, the 15th day of the eighth month in the Chinese calendar, it is an important Chinese holiday, next only to the Spring Festival, and a chance for family reunion under the full moon, a symbol for happiness and prosperity.A staff worker shows newly-cooked moon cakes during a Mid-autumn festival celebration activity held in Tianjin, north China, Sept. 11, 2011. Some 100 children from Tianjin and southeast China's Taiwan attended the activity on Sunday.FAMILY REUNIONIn the railway station of Nanjing, capital city of east China's Jiangsu Province, passengers lined in long queues while waiting for their trains on Saturday.Although the three-day holiday seemed too short for a long trip, Xiao Liang carried several bags with him. "I bought wine for my dad, boiled salted duck for my mom, and health products for my grand parents," the young man beamed.In the southwestern Guangxi Zhuang Autonomous Region, Li Yukun didn't believe that she could reunite with her son for holiday. In fact, she never thought she could see the three-year-old boy again.Two years ago, Xiao Wei (pseudonym) from the Dalun village of the Beiliu city was kidnapped. His parents were desperate. "On special occasions like the Mid-autumn Festival, we shed tears while missing him," Li said.Police finally managed to get clues that a similar boy was adopted in the neighboring Guangdong Province.Li prepared for a feast with policemen to celebrate reunion with Xiao Wei.Since a campaign was launched to rescue trafficked children in Guangxi in 2009, 339 children were saved, half of whom had been sent back and could reunite with their parents in this festival.In Sichuan, 10 prisoners with good records in jail were given an opportunity to go back home for the holiday."In the past I could only receive greetings from my relatives behind the bars," a woman surnamed Chen said. "This year, my dream for home finally came true."Meanwhile, 171 prisoners had their jail terms shortened so that they could be released before the Mid-autumn Festival.
