Scientists from the New York-based Wildlife Conservation Society and other groups have developed a high-tech map that predicts where wolves will prey on livestock, which in turn may allow wildlife managers and ranchers to prevent attacks in the first place. The groups, which also included authors from the Wisconsin Dept. of Natural Resources and University of Wisconsin in Madison, published their results in the latest issue of the journal Conservation Biology.
Using geographic information system (GIS) mapping, the scientists looked at road density, farm size, availability of deer and other factors to develop statewide maps for Wisconsin and Minnesota. Despite dramatic differences in the two states wolf populations, hunting policies, and farm sizes, the maps revealed several similarities among the sites where wolves had preyed on cattle in the past.
Each town in the two states was assigned a color-code ranging from red (highest risk) to blue (lowest risk). Low risk townships included those with lots of cropland, wetlands and open water. Overall, just 0.3 percent of Wisconsins towns were classified as highest risk and none occurred in Minnesota. The two higher risk classes of townships (red and orange) were clustered in two areas that had not previously been identified as problematic.

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.

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...
