The length of time necessary to recover from a mass extinction may seem like a problem from the past, but a team of Penn State researchers is investigating recovery from the second largest extinction in Earths history at the end of the Ordovician 443 million years ago and sees some parallels to todays Earth.
"We are currently in an undeniable biotic crisis," says Andrew Z. Krug, graduate student in geosciences. "We are not just interested in what will disappear, but what will reappear and when the recovery will take place."
During the Ordovician, the majority of life was found in the seas. Scientists consider climate change, specifically widespread glaciation, as the trigger for this mass extinction.

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...
