BEIJING, Aug. 12 (Xinhuanet) -- The risk of developing coronary heart disease is 25 percent higher for women smokers compared with men, according to a study published in the British medical journal "The Lancet".The authors say this could be due to the physiological differences between the sexes with cigarette smoke toxins having a more potent effect on women.The study by Dr Rachel R Huxley from the University of Minnesota and Dr Mark Woodward from Johns Hopkins University involved a meta-analysis of around four million individuals and 67,000 coronary heart disease events from 86 studies.The researchers found that the pooled adjusted female-to-male relative risk ratio (RRR) of smoking compared with not smoking for coronary heart disease (CHD) was 1.25 (25 percent) higher for women.This RRR increased by 2 percent for every additional year of follow-up, meaning that the longer a woman smokes, the higher her risk of developing CHD becomes compared with a man who has smoked the same length of time.The authors say, "The finding lends support to the idea of a pathophysiological basis for the sex difference. For example, women might extract a greater quantity of carcinogens and other toxic agents from the same number of cigarettes than men. This occurrence could explain why women who smoke have double the risk of lung cancer compared with their male counterparts."Worldwide, there are 1.1 billion smokers, of whom a fifth are women.According to the Tobacco Atlas, India, with around a crore female smokers, ranks third in the top 20 female smoking populations across the globe, only the U.S. with 2.3 crore female smokers and China with 1.3 crore female smokers, are worse off.

BEIJING, Sept. 26 (Xinhuanet) -- Fu Ming'ai was reunited with his family on Sunday after 22 years.He is one of the more than 1,400 abducted children who were helped by a national DNA database, which helps match trafficked children and their parents."This shows the superiority of the national database," Chen Shiqu, director of the Ministry of Public Security's anti-human trafficking office, said on Sunday. The database was established in April 2009, when the ministry launched a nationwide crackdown on human trafficking."The ministry's branches across the country have been ordered to take blood samples of unidentified children and enter the information in the DNA database. Meanwhile, parents who report children missing also have their samples deposited in the repository," Chen said. "The database will point out matches for parents and children."DNA testing is accurate for both individual identification and kinship relations, and it is acknowledged as one of the most effective techniques to identify abducted children, according to the ministry.Fu, who was named Liu Qiang by his adoptive family in Shijiazhuang, capital of Hebei province, was picked up by his entire family at the railway station in his home city of Jishou, Hunan province."I resolved to find my parents, because I know I was kidnapped, not abandoned," said Fu, 26, a technician in an auto parts company in Tianjin. He remembered one day when he was 4, someone sprayed a substance in front of his face so that he could not open his eyes, and he was taken on a train.Fu left a blood sample with the DNA database in July. One month earlier, his parents had their blood samples taken when police said this could help the search for their son."I prayed to the gods, even in my dreams, to give my son back. He finally returned," said 55-year-old father Fu Gaomao, who was informed on Thursday of the successful match."Abducted children are found matching with their biological parents in the information bank every day," said Zhang Baoyan, founder of Baobeihuijia, or Baby Back Home, a volunteer group that assists in the nationwide search for missing children and offers support to their parents.

SAN FRANCISCO, Sept. 22 (Xinhua) -- Facebook on Thursday introduced a new feature called Open Graph, enabling users to access and share a wide range of media and lifestyle content on the social network site.According to Facebook's chief executive officer (CEO) Mark Zuckerberg, Open Graph lets users share what they are doing in Facebook-connected apps as they are doing it.These social apps focus on media apps including books, news, music, TV, movies and games, as well as lifestyle apps such as exercise, food, fashion and travel."The last five years of social networking have been about getting people signed up, and getting people connected with their lives. The next five years are going to be defined by the apps and depth of engagement," the young CEO said in a keynote speech at Facebook's f8 developer conference.Take music for example, Facebook integrates with European music streaming service Spotify. If one's Spotify account is connected to Facebook, a message will show up in the Ticker stating the song one is listening to and in the Timeline, a new design of one's profile page. The friends of the user can listen to the same song at the same time by hovering mouse over the song in Timeline or Ticker.Spotify founder and CEO Daniel Ek and movie streaming service Netflix CEO Reed Hastings also took stage as guest speakers to introduce their partnership with Facebook.Zuckerberg also introduced social news reading applications from major news organizations such as The Washington Post and Yahoo News, which allow users to access the content directly on Facebook.Earlier at the f8 conference, Timeline was unveiled as a new feature. It is a new profile design allowing users to scroll vertically through the big moments of one's life in a single page.Zuckerberg assured users that they have complete control over their Timeline, saying they can decide what content will appear and who can see it. The new feature will be available in a few weeks.Since Google launched its own social network "Google+" in June, Facebook has been in a combat mode, striving to roll out new products and features to beat the search giant. In his keynote speech on Thursday, Zuckerberg said half a billion people now use Facebook every day.Two days before the f8 conference, Google announced to open its social network to the public, noting it has introduced 100 new features in the three-month trial.

WASHINGTON, June 6 (Xinhua) -- The tropics and much of the Northern Hemisphere are likely to experience an irreversible rise in summer temperatures within the next 20 to 60 years if atmospheric greenhouse gas concentrations continue to increase, according to a new climate study by Stanford University scientists. The results will be published later this month in the journal Climatic Change.In the study, the Stanford team concluded that many tropical regions in Africa, Asia and South America could see "the permanent emergence of unprecedented summer heat" in the next two decades. Middle latitudes of Europe, China and North America -- including the United States -- are likely to undergo extreme summer temperature shifts within 60 years, the researchers found."According to our projections, large areas of the globe are likely to warm up so quickly that, by the middle of this century, even the coolest summers will be hotter than the hottest summers of the past 50 years," said the study's lead author, Noah Diffenbaugh, an assistant professor of environmental Earth system science and fellow at the Woods Institute for the Environment at Stanford. The study is co-authored by Stanford research assistant Martin Scherer."When scientists talk about global warming causing more heat waves, people often ask if that means that the hottest temperatures will become 'the new normal,'" Diffenbaugh said. " That got us thinking -- at what point can we expect the coolest seasonal temperatures to always be hotter than the historically highest temperatures for that season?"To determine the seasonal impact of global warming in coming decades, Diffenbaugh and Scherer analyzed more than 50 climate model experiments -- including computer simulations of the 21st century when global greenhouse gas concentrations are expected to increase, and simulations of the 20th century that accurately " predicted" the Earth's climate during the last 50 years. The analysis revealed that many parts of the planet could experience a permanent spike in seasonal temperatures within 60 years."We also analyzed historical data from weather stations around the world to see if the projected emergence of unprecedented heat had already begun," Diffenbaugh said. "It turns out that when we look back in time using temperature records, we find that this extreme heat emergence is occurring now, and that climate models represent the historical patterns remarkably well."According to both the climate model analysis and the historical weather data, the tropics are heating up the fastest. "We find that the most immediate increase in extreme seasonal heat occurs in the tropics, with up to 70 percent of seasons in the early 21st century (2010-2039) exceeding the late-20th century maximum," the authors wrote.Tropical regions may see the most dramatic changes first, but wide swaths of North America, China and Mediterranean Europe are also likely to enter into a new heat regime by 2070, according to the study.This dramatic shift in seasonal temperatures could have severe consequences for human health, agricultural production and ecosystem productivity, Diffenbaugh said. As an example, he pointed to record heat waves in Europe in 2003 that killed 40,000 people. He also cited studies showing that projected increases in summer temperatures in the Midwestern United States could reduce the harvest of staples, such as corn and soybeans, by more than 30 percent.

BEIJING, Sept. 28 (Xinhuanet) -- The unmanned Shenzhou VIII, part of China's first spacecraft rendezvous and docking mission, will be launched in early November. Niu Hongguang, deputy commander-in-chief of the program, said on Tuesday the launch has not been affected by the postponed lift-off of the Tiangong-1 space module. Tiangong-1 was to enter a low orbit around Earth at the end of August before being met by Shenzhou VIII. However, the departure was pushed back after a satellite failure on Aug 18. Out of safety concerns, Niu said mission commanders ordered a halt to testing at Jiuquan Satellite Launch Center on Tiangong-1 and its carrier rocket, Long March II-F T1. China Aerospace Science and Technology Corp, which designed and made the rocket carrier that failed to launch, formed an expert panel to investigate and made modifications. A successful launch of a communication satellite on Sept 19 using the Long March II-C showed the measures worked, Niu said, adding: "We now have confidence in the launch of Tiangong-1." The module is a "simplified" space lab that will not only be a docking target, but will also work as a space experimental platform. It will be unmanned for most of its two years of use, although astronauts will spend time onboard for short periods. After Shenzhou VIII, the country will launch Shenzhou IX and Shenzhou X next year to rendezvous and dock with Tiangong-1. Niu confirmed Shenzhou X will be manned. Tiangong-1 can accommodate two to three astronauts. "Whether Shenzhou IX will be manned is up to the results of the first rendezvous and docking mission," he said. The rocket carrier with Tiangong-1 atop stands 52 meters tall, with a takeoff weight of 493 tons. Tiangong-1 was scheduled for launch in between Sept 27 and 30, but due to weather forecasts that predicted a cold air mass would move into the area of Jiuquan Satellite Launch Center, it is believed that conditions on Thursday and Friday will be suitable for takeoff.
