The vortices observed in three rotating superfluids superimposed on the eye of a hurricane
Physicists at the Massachusetts Institute of Technology (MIT) have created the first example of a high-temperature superfluid: a new state of matter in which the atoms in a gas can move with no friction or slowing down whatsoever.
Reported in the June 23 issue of journal Nature, the work is closely related to the superconductivity of electrons in metals. According to Wolfgang Ketterle, the Nobel laureate who heads the MIT group, observations of superfluids may help solve lingering questions about high-temperature superconductivity, which has widespread applications for magnets, sensors and energy efficient transport of electricity.
"In superfluids, as well as in superconductors, particles move in lockstep," explains Ketterle. "They form one big quantum-mechanical wave." Such a movement allows superconductors to carry electrical currents without resistance.

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...
