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."

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
