Recently, psychologists have debated whether high or low self-esteem underlies violent behavior. New research suggests that the most dangerous people are "those who have a strong desire to regard themselves as superior beings." The research, which is published in the July issue of the American Psychological Association's (APA) Journal of Personality and Social Psychology, demonstrates that actual self-esteem may have little if any relation to aggression.
Psychologists Brad J. Bushman, Ph.D., of Iowa State University and Roy F. Baumeister, Ph.D., of Case Western Reserve University conducted two studies in which they explored the connection between narcissism, negative interpersonal feedback, and aggression in 540 undergraduate students. Narcissists, according to the authors, are emotionally invested in establishing their superiority, yet while they care passionately about being superior to others, they are not convinced that they have achieved this superiority. While high self-esteem entails thinking well of oneself, narcissism involves passionately wanting to think well of oneself. In both studies, narcissism and self-esteem were measured, and participants were given an opportunity to act aggressively toward a neutral third party, toward someone who had insulted them, or toward someone who had praised them.

Last month a close friend of mine, a man in his late 40s, got cancer. It was of the colon. He now confronts an uncertain future but his prognosis is good. He's an unrelenting fighter so my bet is that he'll join me in the cancer survivor's club. Mine was melanoma, back in 1992.
These days whenever I think of cancer I think of another cancer fighter, a cultural warrior named Devra Davis. Her new book, The Secret History of the War on Cancer is a disturbing, beautifully rendered work that details how corporate suppression, government inaction and social amnesia have combined to cause an epidemic that makes a mockery of President Nixon's War on Cancer in 1971.
Ten million cancers over the last thirty years were entirely preventable argues Davis.

Ontario could become the first jurisdiction in Canada to place restrictions on bisphenol A, a controversial chemical that is found in hundreds of consumer products, ranging from plastic baby bottles to sports helmets and the resin linings on the insides of most tin cans.
Although Health Canada is currently assessing the safety of bisphenol A, Premier Dalton McGuinty said yesterday the province won't wait until Ottawa rules on the chemical's safety.
He said Ontario plans to appoint an expert medical and scientific panel to advise it on potentially dangerous substances in widespread use, and a priority for this group will be to provide recommendations on how best to deal with bisphenol A.

We blame teen turmoil on immature brains. But did the brains cause the turmoil, or did the turmoil shape the brains?
It's not only in newspaper headlines - it's even on magazine covers. TIME, U.S. News & World Report and even Scientific American Mind have all run cover stories proclaiming that an incompletely developed brain accounts for the emotional problems and irresponsible behavior of teenagers. The assertion is driven by various studies of brain activity and anatomy in teens. Imaging studies sometimes show, for example, that teens and adults use their brains somewhat differently when performing certain tasks.
As a longtime researcher in psychology and a sometime teacher of courses on research methods and statistics, I have become increasingly concerned about how such studies are being interpreted. Although imaging technology has shed interesting new light on brain activity, it is dangerous to presume that snapshots of activity in certain regions of the brain necessarily provide useful information about the causes of thought, feeling and behavior.

For the first time, a study by researchers at Columbia University Mailman School of Public Health, is linking asthma with post-traumatic stress disorder (PTSD) among adults. The study of male twins who were veterans of the Vietnam era suggests that the association between asthma and PTSD is not primarily explained by common genetic influences.
The study included 3,065 male twin pairs, who had lived together in childhood, and who had both served on active military duty during the Vietnam War. According to the findings, among all twins, those who suffered from the most PTSD symptoms were 2.3 times as likely to have asthma compared with those who suffered from the least PTSD symptoms.

Even very small amounts of lead in children's blood -- amounts well below the current federal standard -- are associated with reduced IQ scores, finds a new, six-year Cornell study.
The study examined the effect of lead exposure on cognitive function in children whose blood-lead levels (BLLs) were below the Centers for Disease Control and Prevention (CDC) standard of 10 micrograms per deciliter (mcg/dl) -- about 100 parts per billion. The researchers compared children whose BLLs were between 0 and 5 mcg/dl with children in the 5-10 mcg/dl range.

Rudy Giuliani never misses an opportunity to remind people about his track record in fighting crime as mayor of New York City from 1994 to 2001.
"I began with the city that was the crime capital of America," Giuliani, now a candidate for president, recently told Fox's Chris Wallace. "When I left, it was the safest large city in America. I reduced homicides by 67 percent. I reduced overall crime by 57 percent."
Although crime did fall dramatically in New York during Giuliani's tenure, a broad range of scientific research has emerged in recent years to show that the mayor deserves only a fraction of the credit that he claims. The most compelling information has come from an economist in Fairfax who has argued in a series of little-noticed papers that the "New York miracle" was caused by local and federal efforts decades earlier to reduce lead poisoning.

The number of AIDS cases worldwide fell by more than 6 million cases this year to 33.2 million, global health officials said Tuesday. But the decline is mostly on paper.
Could human induced climate change hysteria be equally exaggerated, used to justify wars
and bring about a fascist state?

Most people spend most of their day sitting with relatively idle muscles. Health professionals advise that at least 30 minutes of activity at least 5 days a week will counteract health concerns, such as cardiovascular disease, diabetes and obesity that may result from inactivity. Now, researchers at the University of Missouri-Columbia say a new model regarding physical activity recommendations is emerging. New research shows that what people do in the other 15 and a half hours of their waking day is just as important, or more so, than the time they spend actively exercising.
"Many activities like talking on the phone or watching a child's ballgame can be done just as enjoyably upright, and you burn double the number of calories while you're doing it," said Marc Hamilton, an associate professor of biomedical sciences whose work was recently published in Diabetes. "We're pretty stationary when we're talking on the phone or sitting in a chair at a ballgame, but if you stand, you're probably going to pace or move around."
