Social structures form through group dynamics, not trait selection
From her work studying social insects, Arizona State University biologist Jennifer Fewell believes that these remarkable animals suggest a an alternate cause behind the development of complex societies. In a viewpoint essay in the September 26 issue of the journal Science, Fewell argues that complex social structures like those seen in social insect communities can arise initially from the nature of group interactions -- the inherent dynamics of networks.
The ability of certain animals to form complex social systems -- particularly humans and social insects like bees, ants and termites -- is considered by many biologists to be one of the pinnacles of biological adaptation and complexity. Social organization allows organisms to share labor, to specialize in tasks and to coordinate efforts. Through organization, social animals accomplish remarkable things - they build colonies supporting millions of individuals, maintain multi-layered social systems, manage complex farming and food production systems, and build elaborate designs and constructions, from giant self-cooling termite towers to skyscrapers.

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...
