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.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
