One of the largest and most anticipated U.S. science construction projects of the past several decades has passed its most significant performance test. The Department of Energys Spallation Neutron Source, located at Oak Ridge National Laboratory, has generated its first neutrons.
Research conducted at the SNS will lay the groundwork for the next generation of materials research. Scientists believe that the greatly improved ability to understand the structure of materials could lead to a virtually limitless number of innovations, including stronger and lighter airplanes, a new generation of batteries and fuel cells, and time-released drugs that target a specific body organ.
Just after 2 p.m. Friday, a pulse of protons from the SNSs accelerator complex, traveling at nearly the speed of light, struck its mercury target. The protons "spalled" neutrons from the nuclei of mercury circulating inside the target. These first neutrons were recorded on equipment specially installed for the commissioning.

Diamond-like carbon is formed differently to what was believed -- machine learning enables development of new model
19.04.2018 | Aalto University
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...
