Although the high-fat, calorie-restricted ketogenic diet (KD) has long been used to prevent childhood epileptic seizures that are unresponsive to drugs, physicians have not really understood exactly why the diet works. New studies by a research team at Emory University School of Medicine show that the diet alters genes involved in energy metabolism in the brain, which in turn helps stabilize the function of neurons exposed to the challenges of epileptic seizures. This knowledge could help scientists identify specific molecular or genetic targets and lead to more effective drug treatments for epilepsy and brain damage.
The research will be presented at the annual meeting of the Society for Neuroscience in Washington, D.C. by Kristopher Bough, PhD, a postdoctoral student in the laboratory of Emory pharmacology professor Raymond Dingledine, PhD.
"These findings support our hypothesis that a dietary regimen can dramatically affect the expression of genes and the function of neurons within the brain, which enhances the ability of these neurons to withstand the metabolic challenges of epileptic seizures," Dr. Dingledine said.

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...
