Researchers have devised a nanoscale sensor to electronically read the sequence of a single DNA molecule, a technique that is fast and inexpensive and could make DNA sequencing widely available.
The technique could lead to affordable personalized medicine, potentially revealing predispositions for afflictions such as cancer, diabetes or addiction. (more…)
*MU study finds disordered eating combined with heavy drinking is common among college students*
COLUMBIA, Mo. – It is well known that eating disorders are common among teens and college students. Heavy alcohol consumption is another well-known unhealthy habit of this age group. A new study from the University of Missouri shows that when college students combine these two unhealthy habits, their long-term health may be affected. “Drunkorexia” is a new term coined by the media to describe the combination of disordered eating and heavy alcohol consumption.
Victoria Osborne, assistant professor of social work and public health, examined the relationship between alcohol misuse and disordered eating, including calorie restriction and purging. Researchers found that 16 percent of those surveyed reported restricting calories to “save them” for drinking. Of the respondents, about three times as many women reported engaging in the behavior than men. Motivations for “drunkorexia” include preventing weight gain, getting intoxicated faster and saving money that would be spent on food to buy alcohol. (more…)
Alcoholism is a tough addiction to kick. Eventually, most people return to drinking. But some Dutch and German psychological scientists have tested a short-term regime that promises to help alcoholics stay sober. Their study is published in Psychological Science, a journal of the Association of Psychological Science.
Heavy drinkers tend to behave impulsively in response to temptation. Meanwhile, their “reflective,” or controlled, responses—the thoughts that would help them resist drinking—are often weak. Most therapies, including Cognitive Behavior Therapy, primarily address the reflective responses. “They deal with the reasons and strategies” for sobriety, said University of Amsterdam experimental psychologist Reinout W. Wiers, the study’s lead author. To boost treatment success, his team developed cognitive-bias modification, or CBM, which, for the first time, “tries to turn around those impulsive responses.” (more…)
A study published on June 21, 2010, in the journal Addiction reveals that drunkenness increases the risk for violent behaviour, but only for individuals with a strong inclination to suppress anger.
