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.

On the way to developing a new active ingredient against chronic infections

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
