Highway travelers view much of the Midwest as little more than barren flatlands. The formation of the region and its rich soils, especially tall grass areas that seemingly should support diverse forests, however, have long fascinated scientists. Newly available, long-term climate data now say the area is the product of weather extremes.
Compared with adjacent regions, the tall-grass area of the plains endures more frequent periods of severe drought, more lightning strikes and subsequent fires from frequent winter thunderstorms, dryer cold weather and more rapid plant and soil moisture evaporation, a team of researchers from the Illinois State Water Survey and University of Illinois at Urbana-Champaign says in the current issue of the journal Physical Geography.
"Beyond the 100 years of scientific curiosity is that these extremes of weather and their frequency or their non-frequency that we have found to be critical factors for the plains are actually very important issues as we face global climate change," said Stanley A. Changnon, a water survey scientist and professor of geography. "The long-term data weve gathered and are analyzing can provide us with very useful guidance as we talk about potential changes to our agricultural systems and to the way we as people live in general."

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...
