We already knew that sleeping helped to reinforce what we’ve learned. But today, a study at the ULg demonstrates for the first time that the brain doesn’t wait until night to structure information. Day and night, the brain doesn’t stop (re)working what we learn.
Positron Emission Tomography (PET-scan) studies carried out recently at the ULg Cyclotron Research Centre have revealed the reactivation of cerebral activity associated with learning new information in humans while they sleep. (1,2) This supports the hypothesis of the role of sleep in memorizing.
Taking advantage of the new opportunities offered by 3 Tesla’s functional Magnetic Resonance Imaging (fMRI)(*), Philippe Peigneux and his colleagues at the University of Liege published findings this week in the international journal PLoS Biology (3). Their study revealed for the first time a phenomenon that occurs during active waking that is similar to reactivation of the cerebral activity linked to learning.

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...
