With a quarter of the Earths land surface affected, the United Nations Convention to Combat Desertification regards desertification as a worldwide problem. Delegates from the 170-plus signatories to the Convention currently gathered in Nairobi have been briefed by ESA representatives and national partners on how satellites are being used to track desertification in Europe.
The Seventh Session of the Conference of the Parties (COP 7) of the United Nations Convention to Combat Desertification (UNCCD) began in Kenyas capital on 17 October and is due to conclude 28 October. The COP is the main decision making group of the UNCCD, which meets regularly to further the Conventions objectives.
The UNCCD was established in 1994, in the wake of the 1992 Earth Summit in Rio de Janeiro which recognised desertification as a major social and environmental problem. Desertification does not so much as refer to the spread of existing deserts as the creation of new ones, through the reduction of productivity of vulnerable dryland areas by soil deterioration and erosion as well as the long-term loss of natural vegetation.

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...
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...
