Research from the University of Michigan shows that the current federal plan to reduce the "dead zone" in the Gulf of Mexico may not be enough to protect the regions half billion dollar a year shrimp industry.
Researchers from U-M, Louisiana State University, and Limnotech Inc, an Ann Arbor-based firm, used three different models to analyze oxygen depletion and to answer two key questions: Is the expanded dead zone human-caused? Will a proposed goal of 30 percent nitrogen load reduction be sufficient to reduce the zone to below 5,000 square kilometers, as agreed to by federal, state and tribal leaders in 2001?
The hypoxic region is an area where water lacks sufficient oxygen to sustain most marine life, and in the Gulf of Mexico it is caused by excess nitrogen---largely runoff from mid-west agriculture, said Donald Scavia, director of the Michigan Sea Grant College Program and professor in the School of Natural Resources and Environment.

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...
