Elderly patients taking the commonly prescribed blood thinner warfarin experience an increased risk for osteoporosis-linked bone fractures, according to a study at Washington University School of Medicine in St. Louis. The results suggest physicians should carefully monitor the bone health of patients placed on the medication and that their patients should take steps to decrease the risk of osteoporosis.
Warfarin, also known by the brand-name Coumadin®, is often given to patients with atrial fibrillation, irregular contractions of the upper chambers of the heart. By interfering with vitamin Ks role in clotting, the drug decreases formation of blood clots, which often accompany atrial fibrillation.
But because vitamin K also interacts with osteocalcin--a protein vital for bone formation--warfarins antagonism of vitamin K has the potential to affect bone strength as well. Osteoporotic fractures occur when the bones become so weakened that minor trauma causes breakage.

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...
