Researchers from the National Cancer Institute (NCI) have developed a mouse model of the premature aging syndrome known as Hutchinson-Gilford Progeria Syndrome (HGPS), according to a report appearing in the journal Nature. Researchers hope the mouse model will facilitate a better understanding of the fatal syndrome, as well as provide clues to the normal aging process.
Currently, there is no treatment for progeria, and children with the rare condition usually die of heart disease in their early teens. Although normal at birth, children with progeria begin to develop growth retardation, thinning skin, and fragile bones as young as 18 months.
"The similarities between mice with this particular mutation and patients with progeria are remarkable," said Colin Stewart, Ph.D., of NCIs Center for Cancer Research, the senior investigator on the study. "Now that weve identified the critical gene and have an animal model that mimics progeria, we have powerful tools for studying both the aging process and this devastating disease."

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...
