Taken from a microbe that thrives in the depths of a Yellowstone National Park hot springs pool, a newly discovered enzyme may be the key to transforming industrial bleaching from environmentally problematic to environmentally green.
Chemical engineer Vicki Thompson and biologists William Apel and Kastli Schaller from the U.S. Department of Energys Idaho National Engineering and Environmental Laboratory discovered that the catalase enzyme from a Thermus brockianus microbe flourishes in both a high temperature and high pH (basic or alkaline) environment.
Catalase enzymes chemically alter hydrogen peroxide into natural products – water and oxygen. Industry is increasingly using peroxide in industrial bleaching processes and needs an environmentally friendly process to handle process wastes. The T. brockianus catalase works well in the hot, alkaline process wastewater where commercially available catalase enzymes do not, so it could be an answer.

Researchers led by Francesca Ferlaino from the University of Innsbruck and the Austrian Academy of Sciences report in Physical Review X on the observation of supersolid behavior in dipolar quantum gases of erbium and dysprosium. In the dysprosium gas these properties are unprecedentedly long-lived. This sets the stage for future investigations into the nature of this exotic phase of matter.
Supersolidity is a paradoxical state where the matter is both crystallized and superfluid. Predicted 50 years ago, such a counter-intuitive phase, featuring...

A localization phenomenon boosts the accuracy of solving quantum many-body problems with quantum computers which are otherwise challenging for conventional computers. This brings such digital quantum simulation within reach on quantum devices available today.
Quantum computers promise to solve certain computational problems exponentially faster than any classical machine. “A particularly promising application is the...
