When planning a summer wedding, it does not really help to hear that "the probability of showers is increasing". A precision weather forecast will predict when the sun comes out or when the rain stops - or foretells if there is fog on the road or shipping lane.
Helsinki Testbed is a project designed to develop precision weather services. It consists of two parallel projects: a wide-ranging research project launched by the Finnish Meteorological Institute in 2005 that focuses on providing new weather services, and another project concentrating on the new observational systems developed by Vaisala Measurements Systems.
Precision weather data requires forecasting on a so-called mesoscale that in meteorological terms means a distance of 1 to 30 kilometres and time span of 0 to 3 hours. For this type of immediate forecasting the conventional observation networks and prediction models are too dispersed.

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...
