U.S. researchers say data from the Human Genome Project are shedding new light on Charles Darwin's theory of evolution. Over the ages we cataloged the anatomical differences between people and eventually biochemical differences, too. Now we can get down to the molecular differences, Carlos D. Bustamante, a professor of computational biology at Cornell University, told The Washington Post. Researchers said many common health problems -- such as obesity, diabetes and high blood pressure -- may...

A U.S. study suggests identifying a single, common variation in a person's genetic information can help predict heart attack or other heart disease events. "This DNA variation at the 9p21 chromosomal region is not a mutation; it is a genetic variant," said Ariel Brautbar of the Baylor College of Medicine, the study's lead author. "We already know that 9p21 DNA variation is associated with a greater risk of heart events, but now we have shown its direct usefulness to patient care by adding it...

Perlegen, a leader in discovering clinically important genetic variations that affect patients' drug response and predisposition to disease, announced today that it has launched a new, proprietary approach to discovering rare genetic variations. The company is now employing this approach in a study of women who have received hormone replacement therapy, to survey a large proportion of the expressed genome for the presence of rare genetic variants that alter women's risk of developing breast...

By Nicholas Wade Two groups of researchers hunting for schizophrenia genes on a larger scale than ever before have found new genetic variants that point toward a different understanding of the disease. The variants discovered by the two groups, one led by Dr. Kari Stefansson of Decode Genetics in Iceland and the other by Dr. Pamela Sklar of Massachusetts General Hospital in the United States, are rare. They substantially increase the risk of schizophrenia but account for a tiny fraction...

Research and Markets (http://www.researchandmarkets.com/research/8cb5a3/evolution_in_healt) has announced the addition of the "Evolution in Health and Disease" report to their offering. A fully revised edition of a volume written by the worlds leading authorities on this subject. It discusses how the evolution of humans and their pathogens have generated important medical issues, covering both infectious and degenerative diseases. It presents important ideas that are not yet sufficiently...

Perlegen Sciences, Inc., a molecular diagnostics company focused on the discovery and commercialization of clinically important human genetic variation, announced today the opening of its portfolio of patented technologies that together enable whole genome association studies capable of assessing an individual's predisposition to specific disease risks and treatment outcomes. The family of six complementary patents now available covers methods of genetic analysis used to detect markers...

ENVIRONMENTAL factors can affect DNA over a person's lifetime in ways that may be inherited, new research has shown. The findings add to the growing evidence that diet and lifestyle have health affects which may pass down generations. They also suggest a possible connection with the ailments of ageing, such as heart disease and cancer. Scientists know that while the genetic code is fixed, it can be affected by chemical "switches" controlled by environmental factors. They can turn...

University of Michigan scientists and their colleagues at the National Institute on Aging have produced the largest and most detailed worldwide study of human genetic variation, a treasure trove offering new insights into early migrations out of Africa and across the globe.Like astronomers who build ever-larger telescopes to peer deeper into space, population geneticists like U-M's Noah Rosenberg are using the latest genetic tools to probe DNA molecules in unprecedented detail, uncovering new...

Canadian scientists have discovered subtle genetic differences between individuals at the DNA level might help identify disease risk factors. Jacek Majewski and Tony Kwan of McGill University said their findings, in part, explain how a relatively small number of differences within DNA protein coding sequences can cause the enormous variety of phenotypic differences between individuals. Majewski noted there are numerous variations in the DNA sequence called single nucleotide polymorphisms,...

Study suggests connection between genetic basis of height and arthritisIn studies involving more than 35,000 people and a survey across the entire human genome, an international team supported in part by the National Institutes of Health (NIH) has found evidence that common genetic variants recently linked to osteoarthritis may also play a minor role in human height. The findings were released today in the advance online publication of the journal Nature Genetics.The variants most strongly...


Word of the Day
baudekin
  • A rich embroidered or brocaded silk fabric woven originally with a warp of gold thread.
'Baudekin' seems to be an alternative form of 'baldachin,' from the Italian 'Baldacco,' Baghdad, the city where the material was made.
