NASA's Operation IceBridge got the 2012 Antarctic campaign off to a productive start with a land ice survey of Thwaites Glacier and a sea ice flight over parts of the Bellingshausen Sea.

During the first few weeks of a campaign, IceBridge typically concentrates on sea ice before it begins to melt as spring temperatures rise, but as often happens in the field, the weather had other ideas.
On Oct. 12, the IceBridge team met with meteorologists at the Punta Arenas airport to discuss weather conditions and make a final decision on where to fly. "The forecast for all sea ice science targets was hopeless," said IceBridge project scientist Michael Studinger. "We decided to take advantage of the unusually good conditions over the Thwaites Glacier area."
Thwaites Glacier is a rapidly-changing ice stream in West Antarctica that flows into Pine Island Bay. A high priority area, Thwaites has been the subject of repeated missions over the past several years by IceBridge and other organizations, such as the Institute for Geophysics at the University of Texas at Austin (UTIG). UTIG is one of IceBridge's partnering organizations, though their survey in this region was part of a project that occurred before IceBridge. Combining new measurements with these previously gathered data gives researchers a more detailed view of parts of Thwaites Glacier, and the resulting information will help with various computer models used to predict how ice sheets change over time.
On Oct. 13, the weather shifted somewhat, allowing for the first sea ice flight of the campaign, a high-priority mission in the Bellingshausen Sea along the west side of the Antarctic Peninsula. This marked the fourth year of data collection over this area. Repeated survey lines on both this flight and the previous one are vital for building a record of change in the Antarctic.
The DC-8 also flew over Burke Island in the Amundsen Sea. Using the DC-8's Coherent Radar Depth Sounder, IceBridge scientists were able to record ice thickness on the small island, something Studinger said is a subject of some interest in the science community.

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...
