A new analysis of adjuvant radiation therapy in women with breast cancer following mastectomy is associated with better survival as measured at 10 years when appropriate doses and fields of radiation are used. The study was published in the January 4 issue of the Journal of the National Cancer Institute . The finding helps resolve controversy over whether radiation therapy improves both survival and risk of recurrence in women with operable breast cancer.
Past studies of radiation therapy in women with operable breast cancer have led to the conclusion that radiation therapy reduces the risk of recurrence of breast cancer but the effects on overall survival have been less clear. However, in some clinical trials, radiation therapy was given in inadequate or excessive doses or did not target an appropriate amount of tissue, including the chest wall and lymph nodes.
Val Gebski, of the National Health and Medical Research Council Clinical Trials Centre in New South Wales, Australia, and colleagues reanalyzed results from 36 clinical trials in which the use of radiation therapy was the sole difference between treatments given to breast cancer patients. They divided trials into three categories: category 1, for studies that used optimal radiation doses delivered to an appropriate amount of tissue; category 2, for studies where patients received an inadequate or excessive dose of radiation; and category 3, for studies in which an inadequate amount of tissue was treated with radiation therapy.

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...
