In a finding akin to discovering pages missing from an antique car repair manual, researchers from The University of Texas M. D. Anderson Cancer Center have linked for the first time two biological processes crucial to cell survival.
The finding, reported in the Dec. 17, 2004, issue of the journal Cell, provides the first link between a cell’s DNA repair machinery and its DNA storage and retrieval machinery. The two processes have been studied independently, and each is essential for proper care and maintenance of the cell’s genetic material, but until now there was little evidence of how the two might work together.
"We have brought together two fields that are essential for proper maintenance of DNA," said Xuetong "Snow" Shen, assistant professor in the Department of Carcinogenesis at M. D. Anderson. "It was generally understood there must be a connection between the two, but no direct connection had ever been seen. We have bridged that gap."

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...
