But a new study, already published as an article in press by Elsevier's journal Geomorphology (http://www.elsevier.com/locate/geomorph) and recently included in the Research Highlights of Nature, shows that there may be erosion of the crest.
Kurt Stüwe of the University of Graz, Austria, together with his colleagues, used a simple numerical landscape evolution model to explore the rate of erosional decay of the Yucca Mountain crest. The model they used is well established in the expert literature, but Kurt Stüwe and his coauthors used it for the first time for a subject of economic relevance.
The researchers predict that the crest could be denuded within 500.000 years to 5 million years, using conservative parameters as the local geology of the region. It may be even more rapid if other factors are involved. The erosion procession also have the potential to affect the long-term stability of this repository.
"In our research of the morphological imprint of tectonics in mountain belts around the world, it was exciting to be able to apply our numerical models to a subject of high interest to experts outside the narrow field of geomorphology or tectonics".commented Dr. K. Stüwe, the study's lead investigator.
The article "Erosional decay of the Yucca Mountain crest, Nevada" by K. Stüwe, J. Robl and S. Matthai appeared in Geomorphology, Articles in Press (28 January 2009), published by Elsevier.

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...
