CHICAGO, Jan. 5 /PRNewswire/ -- A new study in the January issue of the Journal of Vascular Surgery(®), published by the Society for Vascular Surgery®, reveals robust epidemiological evidence that hereditary factors contribute to aneurysm formation in twins. Researchers in Sweden reviewed the data of 172,890 twins born in that country since 1886 and found 265 twins who had developed abdominal aortic aneurysms (AAAs). These individuals ranged from 48 to...

LONDON, November 12 /PRNewswire-FirstCall/ -- - A Love of Pop and Classical Music is Partly in our Genes If you've ever wondered why a close group of friends might like completely different types of music, blame their genes. A study by Nokia (NYSE: NOK) into the musical tastes of nearly 4,000 twins reveals genetic influences on the music people like varies with genre. While, on the whole, musical taste is determined just as much by nature as it is by specific individual...

New findings show that adolescent alcohol use and behavior problems are influenced by the interaction of genetic and environmental factors."In the past, research on genetic and environmental influences on behavior was often conducted in isolation," Danielle Dick, assistant professor of psychiatry, psychology, and human and molecular genetics at Virginia Commonwealth University was quoted as saying. "Some scientists were interested in genetic effects, others in environmental effects. We now...

Adolescent alcohol use and behavior problems are influenced by a combination of genetic and environmental factors. A new study has found that socio-regional factors moderate the importance of genetic influences on early adolescent behavior problems in a way that parallels moderating effects observed for alcohol use later in adolescence. Results will be published in the October issue of Alcoholism: Clinical & Experimental Research and are currently available at Early View. "In the past,...

For those unhappy with their popularity on Facebook, U.S. researchers suggest that social networking is influenced by genetics. Nicholas Christakis of Harvard Medical School and Christopher Dawes and James Fowler, both of the University of California, San Diego, said they were able to show that a person's particular location in vast social networks have a genetic basis. In fact, the beautiful and complicated pattern of human connection depends on our genes to a significant measure,...

The way humans make friends and interact with them may be closely linked to genetic variations, according to new research. "The evidence we present here suggests that egocentric properties are significantly heritable in human social networks," said Nicholas Christakis, of Harvard University in Massachusetts, and James Fowler of the University of California San Diego. "Although it may not be surprising that genetic variation influences net work formation, the effects are large enough that it...

CAMH study reveals that heritability may not be limited to DNA Scientists at the Centre for Addiction and Mental Health (CAMH) have detected evidence that DNA may not be the only carrier of heritable information; a secondary molecular mechanism called epigenetics may also account for some inherited traits and diseases. These findings challenge the fundamental principles of genetics and inheritance, and potentially provide a new insight into the primary causes of human diseases. Your mother's...

Parental education is a strong predictor of socioeconomic status and children's educational environment. Nevertheless, some children continue to experience reading failure in spite of high parental education and support for learning to read. University of Colorado at Boulder psychologists Angela Friend, John C. DeFries and Richard K. Olson examined if genetic and environmental influences on reading disability, the most commonly identified learning disability, interact with level of parental...

According to the National Institute of Mental Health, borderline personality disorder (BPD) is more common than schizophrenia or bipolar disorder and is estimated to affect 2 percent of the population. In a new study, a University of Missouri researcher and Dutch team of research collaborators found that genetic material on chromosome nine was linked to BPD features, a disorder characterized by pervasive instability in moods, interpersonal relationships, self-image and behavior, and can lead...

By Ehrlich, Paul; Feldman, Marcus W Our large brains are surely at the center of our humanity. But it is equally certain that few organs are the subject of more misinformation in scientific and public discourse - especially in the widespread notion that most behaviors controlled by our marvelous brain are somehow programmed into it genetically. A typical treatment in the popular press is this overexcited claim by columnist Nicholas Wade in the New York Times : "When... [the human genome].....


Word of the Day
Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
