The article reveals that scientists are now able to directly measure heat that moves from the molten metal of Earth’s core into a region at the base of the mantle, a boundary located halfway to Earth’s center, about 1,740 miles deep. Measuring heat deep inside the earth is important because the intense temperatures drive processes like the movement of tectonic plates.
For his contribution to the research, Michael S. Thorne, who holds a dual appointment with the Geophysical Institute and the Arctic Region Supercomputing Center (ARSC) at the University of Alaska Fairbanks, created 3-dimensional simulations of earthquakes, allowing scientists to see how seismic waves travel through the earth. These simulations are able to predict ground motion on earth’s surface producing what is known as synthetic seismograms. The simulations of wave behavior assist scientists as they identify how material is moving inside the earth, specifically at the core-mantle boundary deep beneath the Pacific plate.
Thorne put in an impressive 70,000 computing hours on the ARSC IBM supercomputer, “Iceberg,” for this project.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
