"We designed our studies to give doctors several possible treatment options because not all of these strategies may work in clinical applications," Turner said. "However, because vitamin D3 is already in clinical use, our findings show that it is quite promising with few risks. Further, NAP is currently in clinical trials to diminish the severity of other types of brain injury, so we feel this discovery represents a breakthrough for anesthesia-induced neurotoxicity. However, there may be a critical window of efficacy for NAP, which we need to explore further."Of all the approaches that our team studied, using a low dose of ketamine may be both the simplest and most cost-effective, as it suggests children can be pre-treated with the same anesthesia that will be used when they undergo general surgery," Turner added. "In essence, a low-level dose of ketamine primes the child's brain so that the second, higher dose is not as lethal, much like an inoculation."

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...
