Beneficial bacteria have fast-tracked evolution to solve some of our pollution problems, according to an article in the November 2004 issue of Microbiology Today, the quarterly magazine of the Society for General Microbiology. Using the same mechanisms that have allowed hospital superbugs to survive in the presence of antibiotics, many bacteria have changed their behaviour and now use our toxic chemicals as a source of food.
Researchers at the University of Wales Bangor have studied the way that bacteria share DNA in order to adapt and survive by using, and so degrade, synthetic chemicals, like dyes and solvents, released into the environment. These moveable pieces of DNA, called plasmids, can be easily passed between bacteria of the same and often very different species.
“Modern industry releases many synthetic chemicals into the environment which are hazardous to us, our livestock and crops,” explains Professor Peter Williams. However, many bacteria are dealing with this problem and removing these substances. Bacteria are using genes that they already had for degrading natural waste materials and exchanging and rearranging them amongst themselves.

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...
