LOS ANGELES, April 10 (Xinhua) -- Drinking green tea and practicing Taichi may promote bone health of postmenopausal women and reduce the risk of inflammation, a new study suggests.The study, conducted by researchers at the Laura W. Bush Institute for Women's Health at the Texas Tech University Health Sciences Center, focused on postmenopausal women and investigated the potential for green tea to work synergistically with Taichi in enhancing bone strength of postmenopausal women.Originating as a martial art in China, Taichi is a mind-body exercise that utilizes slow, gentle movements to build strength and flexibility, as well as deep breathing and relaxation, to move qi, or vital energy, throughout the body.The study findings were published Sunday at EurekAlert.org, the website of the American Association for the Advancement of Science (AAAS).Carried out as a double-blind, placebo-controlled, intervention trial (the "holy grail" of scientific studies), this experiment involved 171 postmenopausal women with the average age of 57 who had weak bones but not full-fledged osteoporosis. Subjects were divided into 4 groups -- placebo: starch pill (placebo) and no Taichi; GTP or green tea polyphenols (500 mg/day) and no Taichi; Placebo plus Taichi (starch pill and practising Taichi three times a week); and GTP plus Taichi.The study lasted for 6 months, during which blood and urine samples were collected and muscle strength assessed.The results show that consumption of GTP (at a level equivalent to about four-six cups of steeped green tea daily) and participation in Taichi independently enhanced markers of bone health by three and six months, respectively. A similar effect was found for muscle strength at the 6-month time point. Participants taking Taichi classes also reported significant beneficial effects in quality of life in terms of improving their emotional and mental health.Perhaps most remarkable, however, was the substantial effect that both GTP and Taichi had on biological markers of oxidative stress. Because oxidative stress is a main precursor to inflammation, this finding suggests that green tea and Taichi may help reduce the underlying etiology of not only osteoporosis, but other inflammatory diseases as well.In the study, the researchers developed an animal model (the ovariectomized, middle-aged female rat), with which they could effectively study the effects of green tea consumption on protection against breakdown of the bone's microarchitecture, according to the AAAS.In humans, this can lead to osteoporosis, a condition common to older women. The researchers say what they have learned from the animal models might also be applicable to postmenopausal women.There is a "favorable effect of modest green tea consumption on bone remodeling in this pre-osteoporotic population," said lead researcher Dr. Chwan-Li (Leslie) Shen, an associate professor at the institute.The researchers plan to soon complete a more long-term study utilizing more technically savvy measures of bone density, according to the AAAS.

BEIJING, March 10 (Xinhuanet) -- Cigarette displays in shops will be banned and tobacco companies may also be forced to make their products in plain wrappers in an attempt to stop people from smoking, announced the UK government Thursday.The prominent displays and attractive packaging of tobacco have long provided shopkeepers with stable income, keeping addicts hooked and quitters tempted.However, the government's move that will begin as early as spring next year will keep cigarettes hidden away and make it just a tad more difficult for smokers to find their fix."Nearly all adult smokers started smoking before they turned 18 and every year, over 300,000 children under 16 try smoking," said Chief Medical Officer Sally Davies."Smoking is undeniably one of the biggest and most stubborn challenges in public health. Over eight million people in England still smoke and it causes more than 80,000 deaths each year," Health Secretary Andrew Lansley said in his statement on the new law.Now, this move has drawn predictable responses from both sides of the tobacco wars, with health groups cheering and retailers grumbling.The British Medical Association said it was "very pleased" with the announcement, citing research which it said showed that a display ban would play "a key role in discouraging children from smoking and also help smokers quit."On the other hand, industry groups and independent retailers complained it would burden them with the cost of refitting their stores and reduce their already narrow profit margins.And according to media interviews, many people kept skeptical about the real impact the move would have, especially on young smokers.

CANBERRA, March 23 (Xinhua) -- Up to 45 native species in Western Australia's Kimberley region will die out within 20 years if no action is taken, latest study showed on Wednesday.The Priority Threat Management to Protect Kimberley Wildlife report, released by Commonwealth Scientific and Industrial Research Organization (CSIRO) on Wednesday, was commissioned by the Wilderness Society.The report showed that at present, 20.2 million U.S. dollars a year is spent on conservation efforts in the Kimberley, which is home to an assortment of threatened species.However, the report said even if that money was spent properly, the region would still lose some 31 native animals.The numbers of many more birds, reptiles and mammals, such as the Spotted Tree Monitor and the Western Chestnut Mouse, would dwindle.It called for an immediate cash injection of 96 million U.S. dollars to save creatures like the Golden Bandicoot, the Scaly- Tailed Possum and the Monjon Rock Wallaby from extinction.It will follow by an ongoing investment of 40.43 million U.S. dollars annually in the Kimberley to protect its species, as well as boost plant life, help the climate and conserve indigenous land."This investment is great value," one of the report's six co- authors Hugh Possingham said in a statement released on Wednesday."We can save some of Australia's most iconic mammals and birds at a cost of only about one million U.S. dollars per species per year."

SAN FRANCISCO, April 8 (Xinhua) -- YouTube on Friday launched YouTube Live, a homepage for live content on the site and a new live-streaming platform.As part of the service, the world's largest video-sharing website introduced a new browse page, www.youtube.com/live, where users can view live events and add upcoming events to their calendars.YouTube said it would gradually roll out a live streaming beta platform, which will allow certain YouTube partners with accounts to stream live content on the website.The new service will "integrate live streaming capabilities and discovery tools directly into the YouTube platform for the first time," YouTube said in a blog post.U.S. media recently reported that YouTube is planning a major overhaul and is negotiating with Hollywood and music producers for materials to offer on a lineup of new channels, with the aim to compete with broadcast and cable television.
