STOCKHOLM, Aug. 30 (Xinhua) -- Meat diet, a dietary habit popular in some developed countries, can produce more greenhouse gas and thus is likely to actually cause more impact on climate, said a Swedish study published Tuesday.According to Swedish Radio's Ekot news program, the meat diet, also known as Low Carb High Fat (LCHF) diet, doubled the greenhouse gas emission compared with the balanced diet recommended by the Swedish Food Administration.Many Swedish people have abandoned the diet habit of eating root vegetables and fruits, and switched to LCHF diets. The LCHF diet has more meat, fat and unusual greenhouse gas emission. But these root vegetables, such as potatoes and carrots, and other naturally grown vegetables can be planted with less greenhouse gas emission.The report also revealed that many of the LCHF diet advices are actually given by the researchers sponsored by meat industry.

BEIJING, Aug. 22 (Xinhuanet) -- Researchers have discovered how a human egg captures an incoming sperm for fertilization, paving the way to help couples suffering from infertility, according to media reports on Monday.An international team of researchers found that a sugar chain known as the sialyl-lewis-x sequence (SLeX) makes the outer coat of the egg “sticky,” which has proven to be helpful in binding the egg and the sperm.As a result, this observation has filled in a huge gap in the understanding of fertility and provides hope for ultimately helping couples who currently cannot conceive.Scientists and doctors know that a sperm identifies an egg when proteins on the head of the sperm match and bind to a series of specific sugars in the egg’s outer coating. With a successful match of proteins, the outside surfaces of the sperm and egg then bind together before merging, which is then followed by delivery of sperm’s DNA into egg.To identify this molecules, the researchers used ultra-sensitive mass-spectrometric imaging technology to observe and identify which molecules are most likely to be key in the binding process.They experimented with a range of synthesised sugars in the laboratory and found that it is SLeX that specifically binds sperm to an egg.According to the World Health Organisation, infertility affects about 15 percent of reproductive-aged couples around the world and almost one in every seven couples in Britain has problems conceiving a child for various reasons.

BEIJING, Aug. 1 (Xinhua) -- The after-tax CIF (cost, insurance and freight) price of China's jet fuel imports has been set at 7,768 yuan (1,206 U.S. dollars) per metric ton for August, China's economic planner said on Monday.The price adjustment marked the first time for the economic planner to adjust jet fuel prices on a monthly basis after it announced jet fuel pricing reforms in July, according to a notice posted on the National Development and Reform Commission (NDRC)'s website.The NDRC announced on July 7 that it would introduce a market-oriented jet fuel pricing mechanism starting from Aug. 1.Under the new mechanism, the ex-plant price of jet fuel is required to be no higher than the after-tax CIF price of jet fuel imports from Singapore, Asia's largest oil trading and storage center.Taking transportation expenses, trade volumes and international crude oil prices into account, the jet fuel premium is negotiable between jet fuel sellers and buyers and will be reviewed once a year, while jet fuel ex-plant prices will be adjusted on the first day of every month, according to the NDRC.

BEIJING, July 19 (Xinhuanet) -- Lifestyle changes such as exercise, eating healthily and not smoking could reduce the chances of having Alzheimer’s disease by half, researchers said in a study quoted by news reports Tuesday.Hundreds of thousands of patients could potentially avoid the devastating illness by simply changing bad habits, according to the study published in the journal Lancet NeurologyFor the first time, scientists have calculated the extent to which certain lifestyle traits -- including lack of exercise, smoking and obesity -- all contributed to the disease.Researchers found that in the Western world, an inactive “couch potato” lifestyle was the most important possible cause.Smoking, obesity in middle-age, high blood pressure and diabetes all increased the risk as they cause damage to blood vessels in the brain, leading to death of brain cells. Together, the modifiable risk factors contributed to 50 percent of Alzheimer’s cases worldwide.The researchers want to carry out more work to find out how many people can prevent the disease by making small changes to their lifestyle.

BEIJING, July 11 (Xinhuanet) -- Gay and bisexual men account for around one in every three new cases of HIV in China, according to the latest official statistics released by the Ministry of Health.About 5 percent of the group - officially termed men who have sex with men, or MSM - are living with the virus, which is a rate that is 88 times higher than the national HIV prevalence rate of 0.057 percent.The problem is particularly acute in large urban centers, with the prevalence rate in some southwestern cities reaching almost 20 percent.However, the statistics also show that less than half of all gay and bisexual men have access to HIV screening, while about 15 percent of those who are infected are not receiving treatment."Cities are at the heart of China's development and progress and must remain at the forefront of its HIV response," said Michel Sidibe, executive director of the Joint United Nations Programme on HIV/AIDS (UNAIDS), during a workshop about the HIV impact on MSM on Saturday in Chengdu, capital of Southwest China's Sichuan province."Through bold action cities can lead the way to achieving the UNAIDS vision of zero new HIV infections, zero discrimination and zero AIDS-related deaths," he said, according to a UNAIDS news release. "We hope that over the next year, many more Chinese cities will implement MSM strategies."Almost 10 percent of gay and bisexual men in Chengdu are HIV-positive, according to Yang Xiaoguang, director of the city's health bureau. He agreed with Sidibe that cities have a crucial role to play in AIDS prevention and added: "By working to build a strong, multi-sector response in Chengdu, with meaningful community participation, we can scale-up coverage of prevention, treatment and care services among MSM and halt the spread of HIV."During the workshop, senior Chinese health officials, representatives from civil societies and other delegates discussed a new five-year strategy that increases coverage of HIV prevention and treatment for the MSM population and promotes the participation of community organizations.Government estimates put China's population of gay men at between 5 and 10 million, although Zhang Beichuan, a leading expert on HIV at Qingdao University, puts the number closer to 30 million.Tong Ge, coordinator of China's MSM Health Forum, noted the importance of ensuring strong cooperation between the government and society."By building on the experiences of cities like Chengdu, which already have well developed AIDS responses, we can help promote multi-sector collaboration on an equal, orderly basis and strengthen the response to HIV nationwide," he said. "The next step will be to implement similar strategies in other cities nationwide."Chengdu's new strategy underscores the critical role community organizations can play in reaching MSM and other populations at a higher risk of infection, experts at the workshop said.In 2009, China had an estimated 740,000 people living with HIV/AIDS, according to UNAIDS statistics.
