1 The Odyssey space probe Voyager 1 flies through unknown terrain at the edge of the solar system
Since 1977, two spacecraft flying through space, Voyager 1 and 2 Actually, they should just study the outer planets of our solar system. But they proved to be industrious and more durable than I thought. Meanwhile, they have long since left the orbits of all the planets behind and move inexorably to the boundary of the solar system. Your data is still received on Earth, and this week the U.S. magazine Science reported that out there on the edge of our solar system, but something approaching different than previously thought. With Merav Opher, assistant professor in the Astronomy Department at the Boston University Leonard Burlaga, an astrophysicist at the Goddard Space Flight Center, the U.S. space agency, NASA, Greenbelt, Maryland, Stamatios Krimigis, a physicist at the Applied Physics Laboratory at Johns Hopkings University in Laurel, Maryland / chief Scientists from Voyager 1, Susan Dodd, Voyager project manager 1, Jet Propulsion Laboratory, Pasadena, California, Ed St one, Caltech, Voyager Project Scientist.

2 Material wood in urban construction
A wooden building is therefore not only built from a renewable raw material, but also saves significant amounts of CO2 for many decades. Until about 150 years ago wood was the material in the cities have been, because behind the stone facade most Gründerzeithäuser hide wooden ceilings, staircases and pillars. Recently a conference at the University of Stuttgart dealt with “urban timber”, perhaps in our latitudes, a renaissance is imminent with Peter Cheret, Institute of constructions at the University of Stuttgart; Kurt Schwaner, Institute of Timber Biberach University; Arnim Seidel, architect and owner of the Agency of wood.

3. Sustainable timber harvesting: the importance of forest soils
forest soils are more than just a slot for trees: they are of great importance to the ecosystems of forests, water filter and have a decisive influence on the climate. And they are an important economic factor: the Austrian forestry and timber industry generates a production value of 12 billion euros per year, equivalent to about 4 percent of gross domestic product. The quality of the soil is crucial for the yield – You have to understand their delicate balance in order to use them sustainably. Ernst Leitgeb by the Federal Research Centre for Forests has come with his recent photographic atlas of the forest soil types in the German-speaking countries an important contribution to their understanding. With Ernst Leitgeb, ecologist, Ernst Leitgeb, head of the Institute of Forest Ecology and Soils on Federal Research and Training Centre for Forests, Natural Hazards and Landscape (BFW) in Vienna.

4 Rome, Moscow and Berlin: urban development in the capitals of the European dictatorships in the period between the wars.
In the 1930s, the Soviet government had plans to build a “Palace of Soviets”. The tallest building in the world would he be, this one blew, built to commemorate the victory over Napoleon Christ the Saviour Church, which was rebuilt with tremendous use of funds by Boris Jelizin then. “The Hall of the People” was a construction project of Adolf Hitler and Albert Speer, who wanted to transform Berlin megalomaniac “World Capital Germania”. Was modeled on Rome, where at the same time fascist architecture planners made the Colosseum to the center of town until today irritating transformation. At a symposium at the Biblioteca Hertz Liana in urban development in the European dictatorship main cities in the interwar period was. analyzed. Harald Bodenschatz, architecture sociologists, Berlin.
