KATHMANDU, Aug. 7 (Xinhua) -- Ban on smoking in public places will be enforced from Sunday with the Tobacco Control and Regulatory Act-2010 coming into effect.Those smoking in public places will be fined and civil servants will be liable to departmental action.Government offices, corporations, educational institutions, libraries, airports, public vehicles, orphanages, childcare centres, cinema halls, homes for the elderly, cultural centres, children's gardens, hotels, restaurants, resorts, girls' and boys' hostels, department stores, religious sites and industries have been designated no-smoking zones.Health Secretary Sudha Sharma said mass awareness campaign highlighting punishment will be carried out. She also said an inter-ministerial coordinating committee has been formed to enforce the law to ensure people's right to health. Pasting no- smoking notices at every public place will be mandatory.According to The Himalayan Times daily, the ban covers sale of tobacco products and single sticks within a 100-meter radius of educational and health institutions, children's homes, child care centers and home for elders.Anyone selling tobacco products to persons under the age of 18 years and pregnant women will be fined.The Act also prohibits advertising and sponsoring programs in the name of tobacco-related products through media. Offenders will be fined.The government's mass awareness campaign will cover the entire country to ensure effective implementation of the Act.

LOS ANGELES, Sept. 10 (Xinhua) -- Scientists at the University of California Los Angeles campus have announced that they have successfully used new prediction algorithms to forecast climate up to 16 months in advance.Professor Michael Ghil said in a UCLA news release Friday his team used new prediction algorithms based on matching ocean temperature records with new theories on how long-term climate trends are influenced by short-term weather extremes.That's twice as far into the future as previously accomplished.Ghil, a distinguished professor of climate dynamics in the UCLA Department of Atmospheric and Oceanic Sciences and senior author of the research, said the new prediction formulas will give climate experts and governments clues about long-term swings in the El Nino/La Nina oscillation in the Pacific Ocean, which drastically affects weather in the Americas, Asia and Australia.The new forecasting tool uses sea temperatures and has been tested on decades of historical data. The forecasts were then cross-checked against actual climate trends.The UCLA team also said that their 16-month forecasts were more accurate than previous forecasts that went only 8 months forward.Ghil emphasized that the forecasting tools are for climate, which is long-range, global patterns, but not for meteorology, which is short-term weather forecasting."Certain climate features might be predictable, although not in such detail as the temperature and whether it will rain in Los Angeles on such a day two years from now," said Ghil, who is also a member of UCLA's Institute of Geophysics and Planetary Physics. "These are averages over larger areas and longer time spans."The study is currently available online in the journal Proceedings of the National Academy of Sciences (PNAS) and will be published in an upcoming print edition of the journal.

LOS ANGELES, June 5 (Xinhua) -- A latest study has found no evidence that screening for ovarian cancer may reduce the risk of dying from the disease, it was reported on Sunday.Screening, however, does increase the likelihood of unnecessary invasive procedures, according to researchers at the University of Utah.The researchers presented their findings at an on-going meeting of the American Society of Clinical Oncology in Chicago, The Los Angeles Times said.Researchers studied 78,216 women, ages 55 to 74, who participated in the National Cancer Institute's Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial. Half of the women received the usual care from their OB-gyns, and half received a CA 125 screening every year for six years and an ultrasound every year for four years. They were then followed for a maximum of 12 years.The researchers observed 212 ovarian cancers in the screened group and 176 in the normal care group. There were 118 ovarian cancer deaths in the screened group and 100 in the normal care group. The differences were not statistically significant. Overall, there were 2,924 deaths from all causes in the screened group and 2,914 in the normal care group.But the researchers also observed that 3,285 women had false- positive diagnoses from the screening. Among those, 1,080 underwent surgery that included an oophorectomy (surgical removal of one or both ovaries). Fifteen percent of those who had surgery developed major complications as a result. Overall, 1,771 women in the screened group (7.7 percent) had an oophorectomy, compared with 1,304 in the normal care group (5.8 percent)."We conclude that annual screening for ovarian cancer ... does not reduce disease-specific mortality in women at average risk for ovarian cancer but does increase invasive medical procedures and associated harms," the researchers said in the study.New data presented at the meeting also showed that the widely used cancer drug Avastin can improve treatment of ovarian cancer, The Times said.About 21,880 American women are diagnosed with ovarian cancer each year and about 13,850 die from it, according to the American Cancer Society. Because it produces few symptoms, the disease is typically not diagnosed until it has become advanced and spread throughout the body. As a result, five-year survival is only about 30 percent, and the disease is one of the five most deadly cancers among women. Being able to detect the cancer at an earlier stage when it might be more curable could thus, theoretically, improve the survival rate.The tests most commonly used to detect ovarian cancer include a transvaginal ultrasound to look for tumor masses and a blood test that screens for increased levels of a tumor marker called CA 125.

SYDNEY, June 29 (Xinhua) -- A type of dried seaweed sold in Asian food supermarkets in Australia has been recalled after it was found to have high levels of iodine dangerous to pregnant women, local media reported on Wednesday.Food Standards Australia New Zealand (FSANZ) has ordered the recall of Wang Dried Kelp Varech Speche, a Korean brand of the dried seaweed, according to Australian Associated Press (AAP).It has been available in Asian grocery stores and restaurants in the Brisbane and Gold Coast areas of Queensland."The product contains high levels of naturally occurring iodine," FSANZ said in a statement."Regular consumption of these products may cause health problems in some people including pregnant and breastfeeding women."FSANZ said consumers concerned about their health should seek medical advice and should return the products to the place of purchase for a full cash refund.
