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.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
