In the steamy waters of Yellowstone National Parks hot springs lives a type of bacterium that could help make industrial bleaching cheaper and more environmentally friendly. Scientists have found Thermus brockianus bacteria produce a hardy enzyme that can be put to work breaking down hydrogen peroxide in industrial wastewater, producing only harmless oxygen and water as byproducts. Most important, the so-called extremozyme endures harsh industrial conditions better than currently available alternatives and lasts thousands of times longer.
R&D Magazine declared the isolation and production of the enzyme -- named the Ultrastable Catalase Enzyme by the Department of Energys Idaho National Engineering and Environmental Laboratory researchers who found it -- to be one of the 100 most significant technological achievements of 2004. Chemical engineer Vicki Thompson and biologists William Apel and Kastli Schaller from INEEL will be recognized at the R&D Magazine awards banquet in Chicago on Oct. 14, 2004.
"Its exciting that the R&D 100 chose a project involving extremophiles," Thompson says. "It will help spread the word about the practical applications and environmental benefits that can come from extremophilic research."

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.
We carry smartphones in our pockets, the streets are dotted with semi-autonomous cars, but in the research laboratory experiments are still being designed by...

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
