The next big way to clean up toxic sites may be coaxing plants to become janitors, a Michigan State University scientist says.
Clayton Rugh, an assistant professor of crop and soil sciences, explains that phytoremediation – using plants to remove contaminants from the soil – is evolving.
In the early stages of this technology, plants were used like sponges, soaking up toxic substances so they can be safely discarded. The next step, Rugh says, is plants that act like a green Mr. Clean, with roots that make detergents to break down toxins. "What were looking at now are kind of Mop & Glo plants," Rugh said. "These plants make detergents that secrete into the soil, making the plant a kind of site custodian."

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...
