BEIJING, Sept. 30 (Xinhuanet) -- Miners, construction workers and people in hotel and food service industry are most likely to smoke in the U.S., according to new research finding.The finding was contained in a report released Thursday by the U.S. Centers for Disease Control and Prevention (CDC).According to the finding, miners and people in hotel and food service have a cigarette smoking rate of 30 percent, followed closely by construction workers' 29.7 percent.Both rates are much higher than the average smoking rate of 19.6 percent among all U.S. working adults.Workers in the education services industry have the lowest smoking rate, with 9.7 percent, followed by the 10.9 percent of workers in company management, the report said.Low education levels are a factor in high smoking rates, along with poverty and gender, said Ann Malarcher, senior scientific adviser at the CDC."Although some progress has been made in reducing smoking prevalence among working adults," the report wrote, "additional effective employer interventions need to be implemented."Smoking kills an estimated 443,000 each year in the U.S., costing about 193 billion U.S. dollars annually in direct health care expenses and productivity loss.

BEIJING, Nov. 28 (Xinhuanet) -- Scientists in Canada have raised a prospect of reversing Alzheimer's disease by deep brain stimulation, according to media reports Monday.The technique here is known as deep brain stimulation -- applying electricity directly to regions of the brain. It has been used in tens of thousands of patients with Parkinson's as well as having an emerging role in Tourette's Syndrome and depression.The study at the University of Toronto took six patients with the condition. Deep brain stimulation was applied to the fornix -- a part of the brain which passes messages onto the hippocampus.Lead researcher Prof Andres Lozano said you would expect the hippocampus to shrink by five per cent on average in a year in patients with Alzheimer's.After 12 months of stimulation, he said one patient had a five per cent increase and another had an eight per cent increase.Prof Lozano told BBC: "This is the first time that brain stimulation in a human being has been shown to grow an area of your brain.""It was an amazing finding for us," he said.The findings were presented at the Society for Neuroscience conference in November but they have yet to be published in an academic journal.To test whether this is really working, rather than being a fluke result, the researchers are going to perform a larger trial.

WASHINGTON, Jan. 2 (Xinhua) -- A systematic review of previous studies suggests that there may be a positive connection between physical activity and children's academic performance, according to a report published Monday in the Archives of Pediatrics & Adolescent Medicine.A group of scientists at the Vrije Universiteit (Free University) Medical Center in the Netherlands reviewed evidence on the relationship between physical activity and academic performance because of concerns that pressure to improve test scores may often mean more instructional time for classroom subjects with less time for physical activity.The authors identified 10 observational and four interventional studies for review, 12 of which were done in the United States, one in Canada and one in South Africa. Sample sizes ranged from 53 to about 12,000 participants between the ages of eight years and 18 years old. Follow-up varied from eight weeks to more than five years."According to the best-evidence synthesis, we found strong evidence of a significant positive relationship between physical activity and academic performance. The findings of one high-quality intervention study and one high-quality observational study suggest that being more physically active is positively related to improved academic performance in children," the report said.Background information in the article suggests that exercise may help cognition by increasing blood and oxygen flow to the brain, increasing levels of norepinephrine and endorphin to decrease stress and improve mood, and increasing growth factors that help create new nerve cells and support synaptic plasticity."More high-quality studies are needed on the dose-response relationship between physical activity and academic performance and on the explanatory mechanisms, using reliable and valid measurement instruments to assess this relationship accurately," the report concluded.

VIENNA, Oct. 7 (Xinhua) -- A sculpture of late Soviet cosmonaut Yuri Gagarin was presented to the UN Office in Vienna (UNOV) Friday to celebrate "50 Years of Human Spaceflight," the theme of the World Space Week 2011.In 1961, Gagarin completed an orbit around the Earth aboard the Vostok 1 spacecraft, serving as a pioneer of human spaceflight.The sculpture is a gift from the Russian government and would be placed at the Permanent Exhibit of the United Nations Office for Outer Space Affairs (UNOOSA).Attendants of the ceremony include UNOV Director-General Yury Fedotov, UNOOSA Director Mazlan Othman and Head of the Russian Permanent Mission Vladimir Voronkov."Outer space is one of the most exciting and challenging topics, and perhaps of all the important topics on the agenda of the United Nations, none quite captures our imagination like outer space," Othman said in her statement.Meanwhile, speaking highly of Gagarin's achievement 50 years ago, Fedotov stressed that the purpose of the development and utilization of outer space must be to the benefit of all mankind.The UN official said that relevant UN agencies would provide technical assistance to all countries to develop outer space and ensure the benefits in peaceful purpose.On Dec. 6, 1999, the 55th United Nations General Assembly declared the World Space Week to be held every year during Oct. 4-10.
