From the Nobel Assemble press release: The Nobel Assembly at Karolinska Institutet has today decided to award The Nobel Prize in Physiology or Medicine for 2007 jointly to Mario R. Capecchi, Martin J. Evans and Oliver Smithies for their discoveries of "principles for introducing specific gene modifications in mice by the use of embryonic stem cells" Summary This year's Nobel Laureates have made a series of ground-breaking discoveries concerning embryonic stem cells and DNA recombination in mammals. Their discoveries led to the creation of an immensely powerful technology referred to as gene targeting in mice. It is now being applied to virtually all areas of biomedicine – from basic research to the development of new therapies. Gene targeting is often used to inactivate single genes. Such gene "knockout" experiments have elucidated the roles of numerous genes in embryonic development, adult physiology, aging and disease. To date, more than ten thousand mouse gen...

From a National Institutes of Health press release issued on the 29th: After a Decades-Long Search, Scientists Identify New Genetic Risk Factors for Multiple Sclerosis A pair of large-scale genetic studies supported by the National Institutes of Health has revealed two genes that influence the risk of getting multiple sclerosis (MS) — data sought since the discovery of the only other known MS susceptibility gene decades ago. The findings could shed new light on what causes MS — a puzzling mix of genes, environment and immunity — and on potential treatments for at least 350,000 Americans who have the disease. "These studies describe the first genes conclusively linked to MS in more than 20 years," said Ursula Utz, Ph.D., a program director at the National Institute of Neurological Disorders and Stroke (NINDS), a part of NIH. "This breakthrough was made possible through persistence, an elegant search strategy, and genomic data and techniques that were not available until ...
