...boost the quitting success rate would be to match smokers with the right cessation program. A team of researchers, led by Jed Rose, director of the Duke University Center for Nicotine and Smoking Cessation Research, have begun doing just that. In their new study, the scientists screened the entire human genome and teased out a profile of genes that they think are involved in breaking nicotine addiction. Some of the genes influence basic cell communication; others code for enzymes that break down bupropion in the body. Everyone possesses all the genes in question, says Rose, but in different forms...
...Rose found that people with genes that more efficiently code for bupropion breakdown respond better to the drug, while people with genetic variants that improve cell communication - also called adhesion - seem to have an easier time overall in quitting. That makes sense, since addictive behaviors such as smoking are deeply ingrained in the brain, and are strongly tied to social and environmental triggers. That network of neural connections, once cemented, is tough to break. But having certain versions of genes that facilitate neural flexibility - easing the uncoupling of certain brain connections and replacing them with new habits - could, says Rose...
...Centers for Disease Control and Prevention (CDC) analyzed survey data gathered between 1999 and 2006, and found that the prevalence of overweight and obesity among American schoolchildren has plateaued at about 32%. After years of rapid increase - the percentage of 6- to 11-year-olds classified as obese rose from 6.5% in 1980 to 16.3% in 2002 - that sounds like good news. "We can be cautiously optimistic that it seems to be leveling off in recent years," says Ogden...
...then dominated Lebanon. Since Syria disengaged from Lebanon in April 2005 following mass street protests, Suleiman has steered an even course amid feuding Lebanese factions. His priority has been to preserve the integrity of the Lebanese army, widely regarded as almost the only functioning state institution. Suleiman's profile rose considerably last summer when the army engaged in a bloody three-month battle against the Al-Qaeda-inspired Fatah al-Islam faction in north Lebanon. But during the recent street battles in Beirut, Suleiman studiously avoided deploying the army against the warring parties, worried that the military could unravel along...
...other as Iraq's two main Shi'ite power players. In the early days of the occupation, Sistani's call for calm undoubtedly allowed American troops to avoid fierce resistance to their presence in southern Iraq. But Sistani's repeated appeals for peace lost their weight as sectarian violence rose in Iraq, with Sadr leading the Mahdi Army militia in an inexorable year-long quest for Shi'ite revenge following the bombing of a revered shrine in Samarra in early 2006. As a result, Sadr, a mere cleric, towered as the most powerful Shi'ite figure in Iraq, eclipsing...
