Genetics causes some men to test higher on the blood test for prostate cancer – even when they don’t have the disease – report researchers from Wake Forest University Baptist Medical Center and colleagues in the July 16 issue of the Journal of the National Cancer Institute.
The discovery could lead to more accurate testing and fewer unnecessary biopsies, said Scott D. Cramer, Ph.D., lead researcher, from Wake Forest.
"Up to 20 percent of men may have genetic variants that cause levels of prostate specific antigen (PSA) that are about 30 percent higher than other men, which could result in needless biopsies," said Cramer. The research was in collaboration with St. Louis University and Washington University School of Medicine.

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...
