Depressed people may have far fewer of the receptors for some of the brain's "feel good" stress-response chemicals than non-depressed people, new University of Michigan Depression Center research shows.And even among depressed people, the numbers of these receptors can vary greatly. What's more, the number of receptors a depressed person has appears to be linked with the severity of their symptoms - and the chances that they'll feel better after taking a medication.

Which is better, giving more food to a few hungry people or letting some food go to waste so that everyone gets a share? A study appearing this week in Science finds that most people choose the latter, and that the brain responds in unique ways to inefficiency and inequity.

US scientists studying how the brain behaves during decision making have discovered that when people are confronted with moral decisions, they think about efficiency in one part of the brain, and equity in another part of the brain that deals with emotions, and the latter tends to win, suggesting that a sense of fairness is fundamental to human nature.
