Almost half of lung cancers detected by a chest x-ray were early-stage cancers, according to baseline results of a large, randomized clinical trial that is testing the efficacy of a chest x-ray as a screening test for lung cancer. The study results are published in the December 21 issue of the Journal of the National Cancer Institute.
Lung cancer causes one million deaths worldwide every year. When patients begin to experience symptoms of lung cancer, the cancers are often advanced and treatment is rarely successful; 90% of newly diagnosed lung cancer patients die within 2 years of diagnosis.
In 1992, The National Cancer Institute launched the still-ongoing Prostate, Lung, Colorectal and Ovarian (PLCO) Cancer Screening Trial to evaluate screening tests for each of the four cancers. The PLCO Cancer Screening Trial is the largest trial ever conducted in the United States. The 155,000 men and women enrolled in the study were asked about past and present smoking habits, medical history of themselves and their families, and personal characteristics. For the lung cancer portion of the trial, participants were randomly assigned to a control group or to a screening group that received a single-view, posterior–anterior chest x-ray.

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...
