Radiation therapy is an effective way to treat localized prostate cancer. Proven successful treatments include brachytherapy (seed implants) where radiation sources are placed directly into the prostate and external beam radiation therapy where doctors give small daily doses of radiation to the prostate, five days a week, for eight weeks to give enough radiation to kill the cancer cells while sparing nearby healthy tissue.
External beam radiation therapy can be a very effective and minimally invasive treatment. However, the length of treatment can be burdensome for some patients, particularly those who live very far from a treatment facility. Doctors have been investigating ways to shorten the course of the treatment through a technique called stereotactic body radiation therapy, where radiation oncologists give a higher dose of radiation every day for five days. Growing biologic evidence also suggests that delivering radiotherapy in this fashion might be more effective for prostate cancer than conventionally protracted courses.
In this study, researchers from Stanford University treated 41 men with low-risk prostate cancer with SBRT. After a median follow-up of 33 months, no man in the study has seen his cancer return. Men in the study reported side effects, including urinary and rectal problems that were no better or worse than with other prostate cancer radiation treatments.
"There is great enthusiasm in reducing the length of treatment for prostate cancer while also possibly improving its effectiveness, and these early results are very promising for men with early-stage prostate cancer," Christopher King, Ph.D., M.D., an associate professor of radiation oncology at Stanford University School of Medicine in Stanford, Calif., said. "However, it can often take as long as 10 years to see late side effects and recurrences, so we will have to monitor these men closely and cautiously pursue these treatments further before we can confidently say that SBRT is as good as other proven prostate cancer treatments, like external beam radiation therapy, brachytherapy or surgery."

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...
