A broad review of current research on nuclear power economics has been published in the Journal of Renewable and Sustainable Energy. The report concludes that nuclear power will continue to be a viable power source but that the current fuel cycle is not sustainable. Due to uncertainty about waste management, any projection of future costs must be built on basic assumptions that are not grounded in real data.
"The goal of this study was to determine what assumptions are key to reaching conclusions about the relative costs of technologies," says author Sarah Widder, now at Pacific Northwest National Laboratory. She performed the analysis as a science policy intern in Washington D.C. sponsored by the American Institute of Chemical Engineers . "The increasing world demand for uranium and political considerations such as the fate of the Yucca mountain disposal site are two major elements that drive conclusions in one direction or another."
Reprocessing and recycling of spent fuel is an alternative to the "once-through" policy mandated by the 1982 Nuclear Waste Policy Act. While it would minimize high-level radioactive waste and recover additional value from the fuel, the option is controversial because of the risk of weapon proliferation and the significant cost of fuel recovery. Analyses supporting the once-through option assume a continuation in current waste management policies, although they rely on disposal at Yucca Mountain, which has now been deemed unsuitable by the current administration. Analyses supporting a closed fuel cycle, in which unused fuel is recovered and recycled, assume progress in developing new recovery technologies and an increase in uranium costs due to international competition for resources.

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.

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...
