...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, or versions, which either amplify or dampen their effects. "We're going to see a lot more studies like this now, because the tools are there," says...
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...
...While many undergraduates might feel more allegiance to New York or California than Massachusetts, machinations in the Bay State government have more influence on our academic lives than we might imagine. A Patrick-sponsored $1 billion dollar life-sciences bill would allocate money specifically to Harvard for stem cell research, and hopefully encourage the retention of junior faculty in the sciences. Currently pending in the state legislature, this would serve as a boon to Harvard, but other proposed legislation has threatened the autonomy of the University in the past year...
...Inmate Richart Houston, who lives in a cell on Florida’s death row, has summarized the flaws in the judicial system that led the Supreme Court to declare all statewide capital punishment laws unconstitutional in 1972: “Being on death row depends so much on class status, economic status, the ability to get adequate representation, how seriously the prosecutor seeks the death penalty, what kind of jury you get. It’s all pretty arbitrary, really...
...morning of 9/11, Rescorla heard an explosion and saw Tower 1 burning from his office window. A Port Authority official came over the P.A. system and urged people to stay at their desks. But Rescorla grabbed his bullhorn, walkie-talkie and cell phone and began systematically ordering Morgan Stanley employees to get out. They performed beautifully...
