Electric power is needed in remote regions difficult of access, settlements, expeditions and at timber-felling. Where can it be obtained from? Specially for such occasions, researchers from the Moscow Institute of Heating Engineering have invented a wind turbine, which can be delivered by car in a container or by helicopter, for example, MI-26 at external load. The developers promise that the device would supply energy without interruption. “What about dead calm weather?” – you would ask. In this case, the second part of the wind turbine will start working – Diesel generator.
The both devices ensure capacity of 30 kW each. When there is no wind, the Diesel is working, when the wind is gentle, both devices are operating. The LARK’s control algorithm is built in such a way that maximum of energy is collected by the wind turbine from the wind, and the missing part is added by the Diesel. The windwheel diameter is ten meters, it is able of whirling without interruption for twenty five years!
Moreover, the system is fully automated and does not require operations staff’s permanent presence. But the most interesting thing about it is that the device does not require building the foundation, in contrast to ordinary wind turbines. In the regions difficult of access, where stand-alone power sources are needed, construction of the foundation is comparable to the wind turbine itself in terms of cost.

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...
