Washington University earth and planetary scientists say the present-day Missouri River is narrower and more prone to flooding because of extensive damming of the river, especially in the 20th century
Lewis and Clark Missouri River data reveal a broader, healthier stream
The oldest data available on the Missouri River - from the logs of Lewis and Clark - show that water flow on the river today is far more variable than it was 200 years ago. The data also show that the river is some 220 yards narrower at St. Charles, Mo., today at 500 yards across than in 1804 when it spread out some 720 yards.
These changes are due to modifications of the river by the Army Corps of Engineers, say Robert Criss, Ph.D., professor of earth and planetary sciences in Arts & Sciences at Washington University in St. Louis, and Washington University undergraduate student Bethany Ehlmann, an earth and planetary sciences major in Arts & Sciences.

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...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales

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...
