As the future of the tropics unfolds, scientists must explain the dimensions and mechanisms of forest responses to rapid human-population increase and environmental changes
As human populations and their impacts on the world increase, tropical forests are changing in many different ways. Forests are being cleared, burned, logged, fragmented, and overhunted and an unprecedented pace, and they are also being altered in insidious ways by global climatic and atmospheric changes. "The evidence for global effects suggests that a massive reorganization of the structure and dynamics of tropical forests is already underway" writes ecologist S. Joseph Wright, "The tropics support over half of all species and over two-thirds of all people. Without an appropriate commitment from the scientific community, the two are unlikely to continue to coexist," concludes the scientist.
Tropical forest landscapes are changing rapidly in the eyes of scientists working on tropical monitoring plots around the globe, while human populations and their economic activities grow. Old-growth forests become agricultural lands, degraded land is abandoned, urbanization intensifies, and the populations of tropical countries will increase by two billion over the next 25 years.

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...
