Sandia National Laboratories has completed a two-year study of the potential health effects associated with accidental exposure to depleted uranium (DU) during the 1991 Gulf War.
The study, "An Analysis of Uranium Dispersal and Health Effects Using a Gulf War Case Study," performed by Sandia scientist Al Marshall, employs analytical capabilities used by Sandias National Security Studies Department and examines health risks associated with uranium handling.
U.S. and British forces used DU in armor-piercing penetrator bullets to disable enemy tanks during the Gulf and Balkan wars. DU is a byproduct of the process used to enrich uranium for use in nuclear reactors and nuclear weapons. During the enrichment process, the fraction of one type of uranium (uranium-235) is increased relative to the fraction found in natural uranium. As a consequence, the uranium left over after the enrichment process (mostly uranium-238) is depleted in uranium-235 and is called depleted uranium.

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...
