How Economic Changes Affect Disease
“Plop!” You drop one in the pot of boiling coconut milk. The delicate aroma of wings and fur rise into the air. While not everyone’s ideal food choice, the Chamorro people of Guam regard the flying fox - a type of bat that can grow up to a four foot wingspan – as a delicacy. Mostly consumed by men, the entire animal, including the fur and all the insides, are eaten during social gatherings and certain important events. Women sometimes eat the bat as well, but only the breast meat. Yet, this delicacy may have been a leading cause of death for Chamorro adults in the 1940’s.
For many years Guam has been the focus of major studies, as a neurological disease known as ALS-PDC, which exhibits itself with symptoms and fatigues in common with Lou Gehrig’s, Alzheimer’s, and Parkinson’s disease. The presence of the disease in the population of the Chamorro increased at alarming rates, and then just as mysteriously, decreased. Investigations have looked at everything from the water they drink to the air they breathe, but no solid evidence has been linked to the disorders.

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...
