Scientists from the Flanders Interuniversity Institute for Biotechnology (VIB) have achieved a new breakthrough in cancer research. The researchers, connected to Ghent University, have discovered the function of an important mediator involved in suppressing the development of tumors. Using a mouse model, they have shown that absence of the mediator makes the mice susceptible to the development of cancer. Through this research, the scientists are contributing to a better understanding of the molecular mechanisms that control tumor development.
Cell cycle: a vital, controlled process in our body
Every day, the billions of cells that compose our body are being replaced: old cells die and new ones are produced. In the course of this process, each cell goes through a well-organized series of phases. First of all, the hereditary material, or DNA, in the cell nucleus is duplicated. Next, the nucleus divides itself in half; and then the entire cell divides, and the daughter cells grow into completely new cells. Because it is crucial that this cell cycle runs perfectly, various control points have been built in to enable the cell to control the stability of the DNA. If the DNA becomes damaged, the cell cycle will come to a stop.

Cells need to repair damaged DNA in our genes to prevent the development of cancer and other diseases. Our cells therefore activate and send “repair-proteins”...
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...
