Hundreds of miles from the legendary California research centers where pioneering aircraft like the supersonic X-1 were put through their paces, National Aeronautics and Space Administration representatives are pushing the envelope in the Idaho desert with a very different, but equally unique aircraft. These space agency specialists are working with engineers from the U.S. Department of Energys Idaho National Engineering and Environmental Laboratory to test unmanned aerial vehicles as part of a NASA-sponsored program to evaluate potential fire-fighting support from small, robotic planes.
Todays big fires are mapped using manned aircraft, fitted with thermal sensors that fly at night over hot spots and fire perimeters. Data from the planes sensors are transmitted to staff at fire management operations centers who use the information to make decisions on when and where to send in equipment or firefighters. NASA teams from the Ames Research Center and Dryden Flight Research Center are investigating whether it makes sense to use flocks of small, inexpensive UAVs carrying a variety of sensors for such routine surveillance.
Last year, the INEEL UAV program team made history when it simultaneously flew five autonomous aircraft from a common ground station for a project sponsored by the Defense Advanced Research Projects Agency. It was this type of accomplishment, along with the hundreds of associated flight hours that led NASA to the INEEL.

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...
