Treating stroke is all a matter of timing: therapy delivered too late misses the critical window when neurons can still be saved. A report by Stanford University School of Medicine researchers shows that cooling the brain can lengthen the therapeutic window, giving doctors more time to protect brain cells.
The idea of cooling the brain isnt new. Study leader Gary Steinberg, MD, PhD, the Lacroute-Hearst Professor of Neurosurgery and the Neurosciences, said he started cooling brains during brain surgery in 1991. For some types of surgeries, a brain thats 4 degrees cooler than normal seems to resist injury better than a brain at normal body temperature.
In collaboration with Robert Sapolsky, PhD, the John A. and Cynthia Fry Gunn Professor of Biological Sciences, Steinberg has combined this cooling treatment with a form of gene therapy. Together the approaches work better than either technique on its own to save neurons after a stroke. Whats more, cooling the brains in rats slowed the neurons demise, giving researchers more time to administer additional treatment.

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...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
