Age, gender, body size are better predictors of aortic aneurysm; genetics are likely important
Contrary to long-accepted conventional wisdom and to current theories, high blood pressure and other risk factors for plaque buildup are not major factors in the dangerous ballooning of blood vessels near the heart, according to a Mayo Clinic study published in the Journal of the American College of Cardiology this week.
"Atherosclerotic plaques and the risk factors that cause them, including hypertension, classically have been considered important potential causes of the expansion of the aorta," says Bijoy Khandheria, M.D., a Mayo Clinic cardiologist and study author. "Intuitively, it makes sense that high blood pressure would stretch the vessel walls and make them more likely to become enlarged. This study shows that while these risk factors are highly important in a host of diseases and conditions, they are bit players when it comes to causing the dilatation of the aorta that can lead to aneurysm."

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
