Despite the rich knowledge scientists now have of the genes that constitute the human genome, researchers have yet to unravel the precise choreography by which they work – or malfunction – together in the cell in response to triggers from the outside world.
"There is a code we need to understand to determine what happens to a cell under many different conditions, and ultimately to make predictions of how an entire genome is regulated," explains Julia Zeitlinger, a postdoctoral associate at Whitehead Institute for Biomedical Research.
Key to cracking this code, she says, is a set of proteins called transcription factors, which bind to specific genes to produce proteins. Akin to computer programs that return different results depending on the input data, transcription factors can carry out multiple functions in the cell in response to distinct stimuli.

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...
