Researchers at the University of Warwick have trashed the worlds biggest turbulence lab by turning a pleasant stream into a raging torrent - but they say their actions will lead to new understandings in one of the main unsolved problems in physics- turbulence.
Turbulence is one of the main unsolved problems in physics. Turbulent systems fluctuate wildly and understanding this will also help us understand (and put a number on the likelihood of) extreme events in other systems that look the same in terms of the mathematics, such as the weather, and stock market prices.
It is technically very challenging to study turbulence on earth, either in the laboratory or on even the largest computers that are available. A very large experiment is needed, and so researchers have turned to space to use the whole solar system as a turbulence laboratory. The solar system is filled by the suns expanding atmosphere - the solar wind, we see its effects directly here on earth as "space weather" (the northern lights). The solar wind also effects how cosmic rays reach the earth, which may have important consequences for earth weather and climate change.

On January 15, 2009, Chesley B. Sullenberger was celebrated world-wide: after the two engines had failed due to bird strike, he and his flight crew succeeded after a glide flight with an Airbus A320 in ditching on the Hudson River. All 155 people on board were saved.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...
