The sediment sampler was hammered into the ground under the ice in order to recover sediment samples. It is here filled with a mixture of mud and ice.
People are pulling and pushing to guide the 3 ton winch up through the narrow passage to the surface from 8 meters depth. In the other end, the camp bulldozer is pulling hard.
A team of international researchers working on the North Greenland Ice Core Project recently recovered what appear to be plant remnants nearly two miles below the surface between the bottom of the glacial ice and the bedrock.
Researchers from the project, known as NGRIP, said particles found in clumps of reddish material recovered from the frozen, muddy ice in late July look like pine needles, bark or blades of grass. Thought to date to several million years ago before the last ice age during the Pleistocene epoch smothered Greenland, the material will be analyzed in several laboratories, said researchers.
The suspected plant material under about 10,400 feet of ice indicates the Greenland Ice Sheet "formed very fast," said NGRIP project leader Dorthe Dahl-Jensen, a professor at the University of Copenhagen’s Niels Bohr Institute. "There is a big possibility that this material is several million years old -- from a time when trees covered Greenland," she said.

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...
