Why Guinness really is the black stuff. Scientists say stout makes you bitter

The adverts always said Guinness is good for you. But it may be that drinking the black stuff makes you bitter as well as better.

In an intriguing study, scientists have linked tart tastes with an unforgiving  mind.

And the more conservative a person’s views, the more their thoughts are  affected by their tastebuds.

The findings suggest that drinks such as stout, bitter and gin and tonic should be  drunk carefully among friends

Why late to bed, early to rise is a recipe for a heart attack

It is the stuff of nightmares for those whose hectic work schedule or busy family life means getting up early and staying up late.

Sleeping for less than six hours a night greatly increases the risk of dying from a heart attack or stroke, a study has found.

Scientists claim that the modern tendency to delay going to bed in order to get through more of the items on the ‘to do’ list has serious health consequences.

Depression: Here's a gene that may make some folks more susceptible

Depression strikes a huge number of Americans at one time or another of their lives -- and studies show that genes are involved in susceptibility to this awful “Black Dog,” as Winston Churchill used to term his struggle with the mood disorder.

But what are the genes involved? A study in the journal Archives of General Psychiatry implicates one. It directs the formation of a small peptide in our brains, Neuropeptide Y.

Neuropeptide Y is found all over the place in our brains, and prior studies had shown that the levels in our bloodstreams and spinal fluid seem to correlate with how resilient we are to life’s stresses: the more NPY, the more resilient.

Yale University researchers find key genetic trigger of depression

Yale University researchers have found a gene that seems to be a key contributor to the onset of depression and is a promising target for a new class of antidepressants, they report Oct. 17 in the journal Nature Medicine.

"This could be a primary cause, or at least a major contributing factor, to the signaling abnormalities that lead to depression," said Ronald S. Duman, professor of psychiatry and pharmacology at Yale and senior author of the study.

This is pretty big news.  I am hoping they find better ways to deal with depression soon.

Weight bias may harm obese children

NEW YORK (Reuters Health) - The stigma that society attaches to obesity can cause children immediate, and possibly lasting, harm, according to a research review.

Overweight children and teens are commonly teased or ostracized by their peers, and sometimes treated differently by teachers and even parents. This, the review shows, can lead to low self-esteem, poor school performance, avoidance of physical activity and, in the most serious cases, depression and suicide.

Research has long demonstrated the weight bias that heavy children face. In a classic 1961 study, 640 subjects between 10 and 11 years old were shown six pictures of other children their age: one child was overweight; one was normal-weight; and four had some form of physical disability.

When the study participants were asked to rank the children in the order of whom they would like to be friends with, they ranked the overweight child last.

Obesity link to high blood pressure has weakened

NEW YORK (Reuters Health) - It seems that the association between body mass index (BMI) and high blood pressure or hypertension has decreased since 1989, researchers say. The finding suggests that obesity may not have as much of an impact on heart-related disease as previously thought.

"High blood pressure is a leading cause of the global burden of disease," Dr. Pascal Bovet, of the University of Lausanne, Switzerland, and colleagues write in the medical journal Epidemiology. "The prevalence of hypertension, and of several other conditions (including diabetes), is considered to be linked to the worldwide epidemic of obesity."

The researchers examined trends in blood pressure and BMI over a 15-year interval in the Seychelles. Their analysis was based on two independent surveys conducted in 1989 and 2004 using representative samples of the population between the ages of 25 and 64 years.

There was a slight decrease in average blood pressure between 1989 and 2004 in both men and women. The prevalence of high blood pressure changed little during this time -- from 45 to 44 percent in men and from 34 to 36 percent in women.

The percentage of people who were overweight, defined as a BMI of 25 or more, increased from 39 percent to 60 percent between 1989 and 2004.

The Science of Lasting Happiness

Through controlled experiments, Sonja Lyubomirsky explores ways to beat the genetic set point for happiness. Staying in high spirits, she finds, is hard work
Science Image:
The day I meet Sonja Lyubomirsky, she keeps getting calls from her Toyota Prius dealer. When she finally picks up, she is excited by the news: she can buy the car she wants in two days. Lyubomirsky wonders if her enthusiasm might come across as materialism, but I understand that she is buying an experience as much as a possession. The hybrid will be gentler on the environment, and a California state law letting some hybrids use the carpool lane promises a faster commute between her coastal Santa Monica home and her job at the University of California, Riverside, some 70 miles inland. Two weeks later, in late January, the 40-year-old Lyubomirsky, who smiles often and seems to approach life with zest and good humor, reports that she is "totally loving the Prius." But will the feeling wear off soon after the new-car smell, or will it last, making a naturally happy person even more so?
