An instrument aboard NASAs recently launched orbiting infrared observatory has found evidence of organic molecules in an enormously powerful galaxy some 3.25 billion light years from the Earth. So powerful is the source, that it is equal to 10 trillion times the luminosity of the sun, making it one of the brightest galaxies ever detected.
The instrument on the newly named Spitzer Space Telescope (previously called the Space Infrared Telescope Facility, or SIRTF) is the infrared spectrograph, or IRS. James Houck, professor of astronomy at Cornell University, heads the scientific team on the $39 million IRS contract with the Jet Propulsion Laboratory, Pasadena, Calif., a division of the California Institute of Technology, manager of the mission for NASA.
Houck participated in a press conference at NASA headquarters in Washington, D.C., today (Dec. 18) at which the first observations and data from the half-billion-dollar observatory, launched Aug. 25, were released. Among the most spectacular details released were dazzling images taken with the space telescopes infrared-array camera and with its multiband-imaging photometer. The images include a glowing stellar nursery; a swirling, dusty galaxy; a disc of planet-forming debris; and organic material in the distant universe.

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...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
