There may be new treatments for stroke, migraine, Alzheimer’s and other brain disorders, thanks to the discovery of a mechanism for regulating brain blood flow made by researchers at the University of British Columbia.
Scientists found that astrocytes -- cells that surround nerve cells and all blood vessels in the brain -- have a primary role in regulating blood flow within the brain, and hold promise as a target for new therapies. The findings of the two-year study funded by the Canadian Institutes of Health Research (CIHR) and the Canadian Stroke Network were published this week in Nature by UBC post-doctoral fellow Sean Mulligan and Brian MacVicar, a professor in the Brain Research Centre and the Dept. of Psychiatry at UBC and an investigator with the Vancouver Coastal Health Research Institute (VCHRI).
Using a new technique that they developed to study brain blood flow, Mulligan and MacVicar found that a rise of calcium within the astrocytes instructs the blood vessels to constrict, which alters blood flow.

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...
