The Olympiad kick off marks the return of the Games to their ancient birthplace. In Ancient Greece the lands best athletes would test their skills in events like wrestling, and running. However, one constant of the Olympics is the significance of sporting superstars. Philosopher Dr Angie Hobbs from the University of Warwick contends that some top athletes fulfil a vital social function, as they can provide happiness, hope, inspiration, release from care and a sense of national identity.
Today, the Games are transformed into the worlds premier sporting event, but the ancient world also had huge sporting stars, just as we do now. In the next few weeks at least a few of the Olympic victors will be treated as heroes, particularly by their own nations. Likewise, their Ancient Greek Olympic forbears, such as the great wrestler Milo or the boxer Theogenes (unbeaten for 22 years), were lauded by their cities and the emerging Greek nation over 2,500 years ago.
Sports heroes act as a replacement for war heroes in times of peace. A communitys longing for heroes to cheer, motivate and unite them still continues in peacetime, and sport provides the chance for peacetime heroes to emerge.

In the field of nanoscience, an international team of physicists with participants from Konstanz has achieved a breakthrough in understanding heat transport
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...
