Deep-sea ecosystems (at depths of >1000 m) comprise more than 60% of the Earth surface, and are the main reservoirs of global biodiversity.
Climate changes are expected to induce significant modifications in biodiversity on the global scale, yet little is known on the impact of recent climate changes on the deep-sea biodiversity. In the forthcoming issue of Ecology Letters, Danovaro, Dell’Anno and Pusceddu demonstrate that an extensive climate anomaly, which occurred in the Eastern Mediterranean, caused a significant deep-sea biodiversity change.
These results indicate that temperature shifts of 0.05-0.1 °C in the deep sea are sufficient to induce significant changes in species richness and functional diversity. They conclude that deep-sea fauna is highly vulnerable to environmental alteration, and that very minor temperature shifts in deep-water masses can rapidly and significantly alter both structural and functional deep-sea biodiversity. This study provides new elements towards a better understanding of the potential large-scale consequences of climate change.

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
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
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...
