The authors of a 30-year study suggest that declines in fish supply in Ghana can lead to regional increases in the hunting, trade and human consumption of wildlife in this West African nation. Declining fish stocks suggest marine resources are nearing collapse due to overfishing by regional and foreign fleets, most notably fleets subsidized by the European Union. A fisheries collapse would have widely felt consequences for regional economies, human food supply and efforts to conserve nature on land, a new study suggests.
These findings appear in the 12 November 2004 issue of the journal Science, published by AAAS, the nonprofit science society.
The authors call for improved fisheries management from local nations and from the European Union in order to protect biodiversity and promote both food security and poverty eradication. They also emphasize the need for ecologically sound, inexpensive protein alternatives to wildlife and better conservation measures to protect remaining wild animal populations.

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...
Nature does amazing things with limited design materials. Grass, for example, can support its own weight, resist strong wind loads, and recover after being...
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...
