Three of the worlds largest and fastest yachts are in the midst of a non-stop trans-global race, hurtling in excess of 25 knots - 46 kilometres per hour - through the Southern Ocean encircling Antarctica. Iceberg collision is a real risk, but ice-sensitive radar satellites are monitoring the area to provide advance warning to crews.
"It has been a huge tactical – and psychological - advantage to planning our track through the Southern Ocean," says navigator Will Oxley aboard trimaran Doha2006, current leader in the Oryx Quest race. "We have been very cautious with the knowledge of just how much ice is around and just how far north it is."
One million US dollars (€755 000) awaits the winner of the 40 000-kilometre Oryx Quest 2005. Three of the worlds seven multi-hull super-yachts are taking part (a fourth has just been forced out of the race due to structural problems), all of them exceeding 30 metres long and capable of maximum speeds greater than 40 knots (74 kph).

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...
