Veterans With Gulf War Illness Show Brain Changes Linked to Memory Deficits
New research illuminates definitive brain alterations in troops with Gulf War Illness (GWI) thought to result from the exposure to neurotoxic chemicals, including sarin gas, during the first Persian Gulf War. “More than 250,000 troops, or approximately 25% of those deployed during the first Persian Gulf War, have been diagnosed with Gulf War Illness (GWI). Although medical professionals have recognized the chronic and often disabling illness for almost two decades, brain changes that uniquely identify GWI have been elusive until now,” explained researcher Bart Rypma, principal investigator at the Center for BrainHealth at The University of Texas at Dallas.

A Tiny Pronoun Says a Lot About You
The Wall Street Journal: You probably don't think about how often you say the word "I." You should. Researchers say that your usage of the pronoun says more about you than you may realize. Surprising new research from the University of Texas suggests that people who often say "I" are less powerful and less sure of themselves than those who limit their use of the word. Frequent "I" users subconsciously believe they are subordinate to the person to whom they are talking. Pronouns, in general, tell us a lot about what people are paying attention to, says James W. Pennebaker, chair of the psychology department at the University of Texas at Austin and an author on the study.

Study links gene variation to a darker view of life
The Washington Post: Some people just see the world more darkly than others. A group of scientists says that what people observe in everyday life may depend on their genetic blueprint. A particular gene, known to play a part in emotional memories, could also influence where people tend to focus their eyes and attention. “People think there’s a world, and our brain just tells us about it,” said study author and Cornell University psychologist Adam Anderson.

The Key To Learning: Knowing How Learning Works
TIME: What’s the key to effective learning? One intriguing body of research suggests a rather riddle-like answer: It’s not just what you know. It’s what you know about what you know. To put it in more straightforward terms, anytime a student learns, he or she has to bring in two kinds of prior knowledge: knowledge about the subject at hand (say, mathematics or history) and knowledge about how learning works. Parents and educators are pretty good at imparting the first kind of knowledge. We’re comfortable talking about concrete information: names, dates, numbers, facts.

Unhealthy food marketed to youth through athlete endorsements
Yale News: Professional athletes are often paid large amounts of money to endorse commercial products.

The study appears in the November issue of Pediatrics. Analyzing data collected in 2010 from Nielson and AdScope, an advertisement database, the study reveals that adolescents aged 12 to 17 viewed the most television ads for food endorsed by athletes.
