As known, in mordern times, people are suffering more and more work stress, which would hurt our heart, But wether the inevitability exsist between them is not known. Recently, a new study suggested work stress may be an important determinant of CHD among working-age populations, which is mediated through indirect effects on health behaviours and direct effects on neuroendocrine stress pathways.

In this paper ,the researchers point out that stomach hormone turns hungry people into junkies.When volunteers received a dose of a natural hunger-inducing hormone called ghrelin, their brains responded to pictures of food in the same way that addicted people's brains do to cigarettes or drugs, says Alain Dagher, a neurologist at McGill University in Montreal, Canada, who led the study.
And the study also tell us that hormone has its stimulant effects and Memory improvement,mood changes.

The study is the first to implicate faulty protein production with child abuse and suicide. The researchers find that child abuse can leave lasting scars on its victims, both physical and psychological. It may also leave chemical marks in the brains of its victims who will later kill themselves. In the brains of suicide victims, early abuse marks genes that encode ribosomal RNA, key gears in the cellular machinery that makes proteins.
Rebellious Teen? A Brain Area May Hold the Key

Child development experts are scrutinizing a new study that suggests the size of small, almond-shaped structures in the center of the brain known as the amygdalae may hold the key to how aggressive teens behave toward their parents. But researchers at the University of Melbourne's Orygen Research Center in Australia report that these areas of the brain may have a special link when it comes to teens who regularly fight with their parents.

Emotion plays a critical role in many contemporary accounts of decision making, but exactly what underlies its influence and how this is mediated in the brain remain far from clear. Here, researchers review behavioral studies that suggest that Pavlovian processes can exert an important influence over choice and may account for many effects that have traditionally been attributed to emotion...
Social Interactions Can Alter Gene Expression in Brain, and Vice Versa

ScienceDaily (Nov. 7, 2008) — Our DNA determines a lot about who we are and how we play with others, but recent studies of social animals (birds and bees, among others) show that the interaction between genes and behavior is more of a two-way street than most of us realize.
This is not a new idea to neuroscience, but one that is gaining strength, said University of Illinois entomology and neuroscience professor Gene Robinson, lead author of a review on the subject this week in the journal Science
Strong Education Blunts Effects of Alzheimer's Disease, Study Suggests
piggy submitted, created time 1 week 2 days (www.sciencedaily.com)
A test that reveals brain changes believed to be at the heart of Alzheimer's disease has bolstered the theory that education can delay the onset of the dementia and cognitive decline that are characteristic of the disorder.
Scientists at the Alzheimer's Disease Research Center at Washington University School of Medicine in St. Louis found that some study participants who appeared to have the brain plaques long associated with Alzheimer's disease still received high scores on tests of their cognitive ability

According to a study published today in the open access journal Clinical Practice and Epidemiology in Mental Health, gambling addicts don't learn from their mistakes. And it predisposes a person to the development of impulsive or compulsive behaviour, leading to pathological gambling.

A survey released Wednesday that U.S. military personnel fear that seeking help for mental health problems could harm their careers. One of people said a military culture that emphasizes toughness could hinder efforts to get troops to seek help.
Drug taken to stop smoking is linked to traffic mishaps
sea-maid submitted, created time 5 months 3 weeks (www.latimes.com)
A surprising development: the drug that the man in this study had hoped would help turn him into a healthier person instead, he believes, caused an accident in which he could have been seriously hurt, even killed.

One in three doctors is attacked at work every year, yet few of these will have been trained on how to handle the situation. General practitioners, doctors working in accident and emergency departments, psychiatrists, and doctors in training are the most at risk.
"Gay genes" may be good for women
sea-maid submitted, created time 5 months 3 hours (sciencenow.sciencemag.org)
As gay couples race to the altar in California this week, scientists may have found an answer to the so-called gay paradox. Studies suggest that homosexuality is at least partly genetic. And although homosexuals have far fewer children than heterosexuals, so-called gay genes apparently survive in the population. A new study bolsters support for an intriguing idea: These same genes may increase fertility in women.
Benefits of "magic mushroom" therapy are long lasting
sea-maid submitted, created time 4 months 2 weeks (www.nature.com)
The benefits for people who have had positive or even mystical experiences induced by the psychedelic drug psilocybin — the psychoactive ingredient in "magic mushrooms" — linger for as much as a year, according to the latest follow-up study of such patients.
The study offers more support to those who argue that, when used responsibly, some drugs more commonly taken for leisure can safely be used to relieve the stress associated with severe chronic diseases such as cancer.
Depression and the Nobel Prize
sea-maid submitted, created time 4 weeks 21 hours (well.blogs.nytimes.com)
Anyone who has struggled with depression—either in themselves or a loved one—will be moved by the story of Douglas C. Prasher.
Dr. Prasher, who now drives a courtesy van for a car dealer, abandoned a life of scientific research years ago. Trained as a biochemist, Dr. Prasher has struggled over the years with bouts of depression.
His story wouldn’t be notable except for a startling fact: his early research led to a Nobel Prize-winning discovery about the inner workings of living cells. Dr
Economics: In defense of Smith--it's not like he didn't warn us
Darkfrog submitted, created time 3 weeks 23 hours (www.nature.com)
I really liked reading this article. Ostensibly, it's about how all the pro economists know that there are flaws in the traditional economic models, but because no one talks about them to intro students or in the media. Even undergraduate economics students are taught the traditional models in their basic classes, but they graduate and go into financial professions without anyone ever mentioning the points at which these models fail to work.
The public is left to assume that the models are wrong and that the economists must have some spooky ulterior motive
