American Psychiatric Association issues statement on compulsive shopping

There have been a number of erroneous reports in the media indicating that the American Psychiatric Association is planning to add "compulsive shopping disorder" to the list of approved mental disorders. We would like to correct this misinformation. At this time, the American Psychiatric Association (APA) has no plans to add compulsive shopping to the list of mental disorders in the next edition of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-V), due for publication in 2010. In addition, APA is not altering the current edition, Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition Text Revision (DSM-IV-TR), to include compulsive shopping as a disorder.

Move over, morphine: Researchers at the University of Arizona and the University of New England have developed a new narcotic based on a natural painkiller found in the body that appears in animal studies to be more potent but less addictive. Although researchers have developed many narcotic-type painkillers that rival morphine in strength, few have had the ability to avoid its potential side effects, until now. These side effects include severe constipation, reduced blood pressure and breathing, and addiction.

Advanced Sonar Improves Mine Detection

Submarines should have improved ability to detect undersea explosive mines thanks to advancement of a type of sonar that uses a relatively small antenna to mimic a much larger one. The technology bounces sound waves off of the sea floor, one small patch at a time. Onboard processors then combine these individual glimpses to create a larger image of the area surveyed.
