Excessive Chatting on Facebook can lead to Depression in Teenage Girls

Girls can be prone to anxiety and depression by talking too much to their friends through texting, email and social networking sites such as Facebook.

Repeated conversations among adolescent girls, known as co-rumination, can be unhelpful, particularly if it is about romantic disappointments.

Frequently discussing the same problem can intensify into an unhealthy activity for those who use Facebook and other electronic means to obsess about it, according to the researchers.

Quebeckers launch class action over cancer cluster near military base

Marie-Paule Spieser lost her best friend to a rare form of liver cancer in September of 2000. As an experienced nurse in her mid-40s, Ms. Spieser knew something had to be wrong.

Her friend's husband had also been diagnosed with cancer and it seemed nearly every household in the neighbourhood where she lived was stricken with some form of the disease.

Then a few weeks later, just before Christmas, Ms. Spieser along with the 4,000 other residents of Shannon, a small town located just outside the Valcartier military base near Quebec City, learned that their water supply had been contaminated for years with the chemical solvent trichloroethylene, or TCE, a probable carcinogen.

Can a Person be Scared to Death?

Scared to death: A terrifying situation can lead to fatal heart rhythms.
A 79-year-old woman dies in North Carolina after a heart attack brought on by terror.

A Charlotte, N.C., man was charged with first-degree murder of a 79-year-old woman whom police said he scared to death. In an attempt to elude cops after a botched bank robbery, the Associated Press reports that 20-year-old Larry Whitfield broke into and hid out in the home of Mary Parnell. Police say he didn't touch Parnell but that she died after suffering a heart attack that was triggered by terror. Can the fugitive be held responsible for the woman's death? Prosecutors said that he can under the state's so-called felony murder rule, which allows someone to be charged with murder if he or she causes another person's death while committing or fleeing from a felony crime such as robbery - even if it's unintentional.

But, medically speaking, can someone actually be frightened to death? We asked Martin A. Samuels, chairman of the neurology department at Brigham and Women's Hospital in Boston.

Understanding Consciousness: Measure More, Argue Less

One sign of progress in unraveling the mind-body problem is the development of new and ingenious ways to measure consciousness.

At the heart of science are judicious observations and measurements. This reality presupposes that something can be measured. But how can consciousness - the notorious ineffable and ethereal stuff that can't even be rigorously defined - be measured? Recent progress makes me optimistic.

Consider a problem of great clinical, ethical and legal relevance, that of in­ferring the presence of consciousness in severely brain-damaged patients. ­Often the victims of traffic accidents, cardiac arrests or drug overdoses, such patients have ­periods when they are awake, and they may spontaneously open their eyes. On occasion, their head turns in response to a loud noise, or their eyes might briefly track an object, but never for long. They might grind their teeth, swallow or smile, but such activities occur sporadically, not on command. These fragmentary acts appear reflexlike, generated by an intact brain stem.

FDA holds safety hearing on 50-year-old painkiller

Washington - Call it the cold case file of drug safety. Federal health officials convened a public hearing Friday on whether to ban Darvon, a painkiller first approved in 1957, when there were few alternatives for treating pain except aspirin and powerful narcotics.

Now mainly marketed as Darvocet, which includes a dose of acetaminophen, the drug remains one of the top 25 most commonly prescribed medications. More than 20 million prescriptions were written in 2007.

Non-Stick Cookware Chemicals Cause 150 Percent Increase in Infertility

Is eating off non-stick cookware a new form of chemical birth control? New research published in the journal Human Reproduction reveals that women with the highest levels of Perfluorinated chemicals (PFCs) in their blood are 150% more likely to have difficulty conceiving a child.

PFCs are commonly used in non-stick cookware, and eating off non-stick cookware inevitably results in the consumption of these chemicals. Even so-called "diamond" non-stick surfaces are easily scratched. A previous report by NaturalNews exposed the truth about so-called "diamond" non-stick cookware surfaces.

PFCs are also known to impair fetal growth, harm the liver and suppress immune system function. They're also highly toxic to the environment, both during the manufacture and disposal of non-stick cookware products.

So why do the chemicals remain legal in the U.S. and other countries? Because they're made by powerful corporations like DuPont (the owner of the Teflon trademark). Those corporations hold great sway over U.S. regulators, and they routinely distort the truth to hide the dangers of their chemicals.

Exercise Gives The Brain A Workout, Too

New studies suggest that exercise can help your brain to function better and that may have important implications for kids. The Early Show's Dr. Debbye Turner Bell delves further into the topic.

According to Bell, researchers are finding that exercise can do more than keep you fit; it can also make you smarter. One school in Illinois has developed a program that gets kids moving and learning.

Kids Who Spend More Time Outdoors Have Better Vision

Study finds youngsters who are parked indoors more likely to develop myopia.

Kids who spend more time outside -- and away from the television set -- are less likely to develop myopia, the inability to see things clearly at a distance.

The new report, from researchers in Boston, doesn't determine whether too much indoor activity actually causes poor eyesight. And even if it does, researchers haven't pinpointed what the exact mechanism might be.

Those Who Feel Rejected Direct Hostility Toward Others

Getting the cold shoulder can turn some people into hotheads.

A University of Kentucky study found that people who feel socially rejected are more likely to view other people's actions as hostile and also more likely to behave badly toward other people. The researchers said their findings may help explain why social exclusion is often linked to aggression that, in some cases, is so extreme it can result in school shootings and other tragedies.

"Prior case studies show the majority of school shooters have experienced peer rejection. And while not everyone who feels rejected reacts violently, we found they tend to act out aggressively in other ways. We wanted to explain psychologically why this happens," study author C. Nathan DeWall said in an American Psychological Association news release.

The Paradox of Temptation

Does the mere availability of something tempting weaken the will to resist? The answer is of more than theoretical interest to public health experts, and the problem goes far beyond serious addictive disorders. Just think of all those Christmas cookies in your office recently. As our national obesity crisis shows, difficulties with discipline and self-control are widespread and harmful.

Every self-control challenge is a tradeoff of one kind or another, and with chocolates and other desserts it's a tradeoff between satisfying a sweet tooth and commitment to good nutrition. Although it seems intuitively obvious that the dieter should not keep bonbons in every room of the house, psychological theory argues the opposite. According to counteractive self-control theory, we deflate desire for readily available temptation when indulging conflicts with pursuit of more important goals.

Three psychologists recently decided to test the paradoxical view of temptation based on counteractive self-control theory. Kristian Ove Myrseth and Ayelet Fishbach of the University of Chicago and Yaacov Trope of NYU predicted that increasing the availability of sweets would indeed deflate desire for them.
