A new study suggests that
bullying makes people feel good. Now, this may not come as a huge surprise, given the stereotypical images in films and TV shows of bullies ganging up on their targets, laughing wickedly as they torture them with physical or verbal insults. But most depictions suggest fairly simple explanations for bullying behavior: the desire for power, wealth, etc., with little or no regard for morality. |

Twice as many new cases of diabetes were diagnosed in the US than 10 years ago, according to the latest government statistics, which covered 2005-2007. The alarming trend, which researchers blame on the obesity epidemic, has struck hardest in the South.

Now that the jack-o-lanterns have gone dark and their sharp-edged features are beginning to soften, it's time to hunker down for the coming winter. That means, among other things, losing the sun an hour earlier. For some, the advancing twilight puts a nostalgic period on the end of Indian summer.

With a little help from snapdragons, purple tomatoes may open a new chapter in the debate over genetically modified foods. Such products, often developed to improve crop yields by building in resistance to pests and disease, have been the center of controversy. Opponents point to uncertainty over how they might alter the environment, how they might affect food chains, and how they might differ nutritionally from their natural counterparts. |

A new study published in the
British Medical Journal has sparked new debate over doctors' use of
placebos in treating their patients. The research found that many doctors prescribe vitamins, sedatives or nonprescription painkillers to treat chronic medical conditions such as arthritis. In most cases, the doctors do not plainly tell their patients that they are being given placebos. |

High blood pressure affects more Americans than ever, according to a new report in the medical journal
Hypertension. Although one might be tempted to blame the current economic crisis, the increasing trend toward hypertension correlates with another trend that's been building far longer than the financial meltdown: the obesity epidemic. As unsettling as that news is, though, it's somewhat mitigated by the fact that the number of people who are getting treatment for the condition is also on the upswing. |
