Why diets don't work? Starved brain cells eat themselves (8/13/2011)

A report in the August issue of the Cell Press journal Cell Metabolism might help to explain why it's so frustratingly difficult to stick to a diet.

Out-of-the-blue panic attacks aren't without warning -- body sends signals for hour before (8/6/2011)

Out-of-the-blue panic attacks aren't without warning -- body sends signals for hour beforePanic attacks that seem to strike out-of-the-blue are not without warning after all, says psychologist Alicia Meuret, Southern Methodist University, Dallas.
