As any dedicated video game player knows, the first requirement for using a weapon or tool is finding it. And it is no different for cell biologists and clinicians who want to take control of gene expression in cells to create therapies to treat disease. While cells have a variety of ways to control gene expression, the trick for players in this game is to recognize them amidst the incredibly complex background of cellular machinery.
Now, in a paper in the January 28th issue of Cell, Lynne E. Maquat, Ph.D., professor of Biochemistry and Biophysics at the University of Rochester Medical Center, and her team have identified a novel pathway for RNA degradation, a form of regulation that has garnered significant attention in recent years, and one that has the potential to produce a new set of tools for physicians to use to fight disease.
Most of the gene-control tools researchers have collected thus far involve the first step in gene expression, in which DNA is copied into RNA transcripts. However, recent discoveries have shown that many of the tools cells use to regulate genes work after transcription, by moderating the activity and the life span of the RNA itself.

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...
