Most psychology research is done by asking a big group of people the same questions at the same time. “So we might get a bunch of Psych 101 undergrads, administer a survey, ask about how much they use alcohol and what their mood is, and just look and see, is there a relationship between those two variables,” says Daniel J. Bauer of the University of North Carolina at Chapel Hill, the author of the article.
But a one-time survey of a bunch of college students can only get you so far. For example, it might find that sad people drink more, but it can’t tell us whether people drink more at times when they are unhappy, whether the consequences of drinking instead result in a depressed mood, or whether the relationship between mood and alcohol use is stronger for some people than others.

Even patients who appear to have a successful response to antidepressants may not experience total elimination of depression symptoms, a new study suggests. Some of the most common persisting symptoms include insomnia, sadness and decreased concentration.
Study participants reported three to 13 residual symptoms of depression even if their antidepressant treatment was considered effective, said study researcher Shawn McClintock, a clinical neuropsychologist at University of Texas Southwestern Medical Center.
Plus, 75 percent of all study respondents said they experienced at least five or more symptoms of depression despite treatment, McClintock said.

A preliminary study suggests a history of childhood trauma among adults displaying post-traumatic stress disorder may cause accelerated aging.
Researchers at the San Francisco VA Medical Center and the University of California, San Francisco discovered that individuals with PTSD had altered chromosomes.
For these individuals, the part of the chromosome called the telomere — a DNA-protein complex whose function is to protect the chromosome from damage and mutation — was shortened and thus damaged.

Could a traditional food have pain- and inflammation-reducing effects similar to over the counter pain medicine like ibuprofen?
Scientists from Italy, Spain, the U.S. and Australia have discovered that extra virgin olive oil can provide significant health benefits, including the ability to help reduce pain and inflammation.
This robust, flavorful oil is an example of the food as medicine concept, that foods can have a powerful impact on health.

A team of scientists from Columbia University College of Physicians and Surgeons and Weill Cornell Medical College has shed light on the molecular workings of transporter proteins, molecular machines embedded in the cell membranes of neurons that modulate the transfer of signals between cells and recycle neurotransmitters.
The research, published today in the journal Nature, reveals with unprecedented detail how the molecule performs its task, says one of the senior authors, Dr. Jonathan Javitch, the Lieber Professor of Experimental Therapeutics in Psychiatry and professor of pharmacology in the Center for Molecular Recognition at Columbia University Medical Center. “This level of understanding may ultimately lead to improved treatments for psychiatric disorders and increase our understanding of how drugs such as cocaine work.”
