Utah State University researchers recently discovered a new bacteria that is a natural cleanser for contaminated soil. The bacteria, now being used around the world, is an inexpensive and highly effective solution to pollution.
“This project shows mother nature’s capability to be a master engineer,” said Ron Sims, biological and irrigation engineering department head. “Past disposal practices and accidental spills have put these carcinogens in our environment, and nature has figured out a way to cleanse herself. We want to be able to understand it better through genomic analysis.”
Engineers often use other human-made chemicals to clean up contaminated sites, but these microbes will provide a natural solution, said Sims. Bioremediation cleans up the environment by allowing living organisms to degrade or transform hazardous organic contaminants using natural biology. It offers an attractive solution to pollution cleanup because it can occur on-site and at relatively little cost compared to other alternatives, he continued. The team received a $1.5 million dollar contract from the U.S. Department of Energy to further study the bacteria. Sims discovered the microbes on a landsite in Libby, Mont. contaminated by chemical carcinogens called polycyclic aromatic hydrocarbons (PAH’s). The site had been used by industry as a place to apply preservatives to wood, yet Sims found the land to be relatively free of toxins and asked the question, why? After conducting soil analysis tests, Sims found microbes in the soil that had destroyed the toxic chemicals.

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...
