A recent study of more than 2,000 identical twins found that medical problems early in life, rather than the neurotoxic effects of anesthesia, are likely linked to an individual's risk for developing learning disabilities. The study's findings, reported in the journal Twin Research and Human Genetics, contradict research published earlier this year, which concluded that receiving anesthesia younger than age four is associated with subsequent learning problems.Robert Althoff, M.D., Ph.D.,...

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,...

Opiates such as morphine and codeine are the primary prescription medication for pain relief, but just how well these drugs work varies significantly from patient to patient. And no one really knows why. Certain patients may require 10 times the amount of opiates, also known as narcotics, to get the same level of pain relief as others. Side effects such as nausea or sedation can be debilitating to some, while nonexistent for others. Addiction potential also varies from patient to...

Study into causes of disc degeneration awarded Kappa Delta Award from American Academy of Orthopaedic SurgeonsWhat do you learn by looking at the spines of hundreds of Finnish twins? If you are the international team of researchers behind the Twin Spine Study, you find compelling proof that back pain problems may be more a matter of genetics than physical strain.The findings of the Twin Spine Study, an ongoing research program started in 1991, have led to a dramatic paradigm shift in the way...

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].....

LONDON -- Forget family influence and upbringing. When it comes to being an entrepreneur, genes seem to play an important role, scientists said on Monday. A study of identical twins by researchers in Britain and the United States suggests family environment has little influence because nearly half of a person's propensity to be self-employed, or entrepreneurial, is due to genes. "This relatively high heritability suggests the importance of considering genetic factors to explain why some...

By Graciela Flores NEW YORK (Reuters Health) - Genes apparently have a larger role in women than in men in the risk of developing major depression, based on the results of a new twin study appearing in the current issue of the American Journal of Psychiatry. "Previous studies gave us hints of two different kinds of genetic differences between men and women: quantitative -- whether the overall role of genes and environment differs -- and qualitative -- whether the actual liability genes are...

WASHINGTON (Reuters) - Identical twins grow apart,genetically, as the years pass, a team of European and U.S.researchers reported on Tuesday. Their study of identical twins show the genetic code itselfdoes not change, but rather chemical changes after birth alterthe way the gene is expressed, a process known as epigenetics. The study, which involved researchers and twins in Spain,Denmark, Britain, Sweden and the United States, can help shedlight on how environment and genes interact to...

"About 50 percent of adult-onset weight change remains genetic," principal investigator James C. Romeis, a professor of health services research, said in a prepared statement. He studied nearly 4,000 sets of male...
