“The Ontario elk restoration program has met with great success primarily due to the collaborative, multi-partnered approach to wildlife management,” says Dr. Rick Rosatte, author of the report and senior research scientist with the Ontario Ministry of Natural Resources. Although the transferred elk experienced a 41 percent mortality rate between 1998-2004, the majority of surviving elk were able to reproduce. According to the program’s 2004 data, 375 to 440 elk are currently living in Ontario.
Dr. Rosatte is quick to point out that the program faced many challenges. Many of the reintroduced elk did not survive long after being transferred, particularly due to wolf predation, illegal hunting and stress from the transfer process. However, the death rate is decreasing each year, suggesting that the animals are adapting to their new home.
Although pleased with the program’s success to date, Rosatte asserts that the work is far from over. “Our challenge for the future will be to develop accurate methods to estimate elk numbers and locations, so that elk can be managed in a sustainable manner, and in a way that minimizes conflicts between elk and humans.”

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.

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...
