Probing the last genomic frontier of higher organisms, an international team of scientists has succeeded in sequencing a little understood - but critical - genetic domain in rice.
In doing so, the group, led by Jiming Jiang, a professor of horticulture at the University of Wisconsin-Madison, and C. Robin Buell of the Institute for Genomic Research in Rockville, Md., has exposed a supposedly barren region of a rice chromosome known as the centromere. The work, published in the current (Jan. 11) online editions of the journal Nature Genetics, reveals for the first time that a native centromere, typically composed of enormous spans of indecipherable, non-coding DNA, contains active genes.
The feat promises to help fill in a key genetic void and enhance the scientific understanding of chromosomes, the molecular structures that are found in all animal and plant cells, and are the essential carriers of hereditary information, enabling the processes of cell division and replication.

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...
