Your breakfast this morning came at a cost not only to your wallet. Your bowl of Cheerios and cup of coffee and all the other meals for the other 6 billion people in our world cost the Earth a bit of its water, a bit of its ecological diversity, contributed to its pollution and may one day cost us our livelihood.
In the July 22, 2005 issue of the journal Science, co-author Terry Chapin, professor of ecology at the University of Alaska Fairbanks (UAF) Institute of Arctic Biology (IAB), and colleagues point out that modern land-use practices may be trading short-term increases in food production for long-term losses in the environment’s ability to support human societies. Part of the solution, according to Chapin, is the students in UAF’s Regional Resilience and Adaptation Program (RAP).
Local land-use practices such as clearing tropical and boreal forests, practicing large-scale agriculture, expanding urban centers and intensifying farmland production are so pervasive their effects are now observed globally. Fertilizer use, which has increased 700% in the past 40 years, and human-caused atmospheric pollution now negatively affect water quality and coastal and freshwater ecosystems. Biodiversity is lost due to modification, fragmentation and loss of habitats, soil, and water, and exploitation of native species. Land-use practices play a role in changing the global carbon cycle, and possibly, the global climate.

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...
