The oldest ecological experiment in the world, set up almost 150 years ago to see whether inorganic fertilisers could produce more grass than traditional animal manures, is becoming an important source of evidence on the impact of climate change on genetic variation in plants.
Speaking at the British Ecological Society’s Annual Meeting, being held at Manchester Metropolitan University on 9-11 September 2003, Professor Jonathan Silvertown of the Open University will explain what the Park Grass Experiment has taught ecologists over the past century and how this uniquely long dataset has shed new light on many ecological problems, including the link between the genetics and population dynamics of species.
Set up in 1856, three years before Charles Darwin published his Origin of Species, the Park Grass Experiment is a hay meadow at Rothamsted Research to which a series of different fertiliser treatments have been applied annually. As well as measuring the yield of hay from each plot, ecologists have also measured the change in species composition in the meadow, and kept samples of the hay cut from it over the 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...
