This innovative instrument is aimed to hunt the elusive gravitational waves using extremely sophisticated technological solutions.
On July 23rd in Cascina, near Pisa (Italy), the new Virgo interferometer will be inaugurated. The innovative Virgo gravitational-wave-detector is the outcome of more than ten years of collaborative research and development between the National Institute of Nuclear Physics (Infn, Italy) and the National Scientific Research Centre (Cnrs, France). Letizia Moratti, Italys Minister for Education and Research, and Claudie Haigneré, the French Minister for Research and New Technologies, will participate in the inauguration ceremony. Journalists are also being invited to tour the scientific infrastructure and interview researchers.
The existence of gravitational waves is one of the most fascinating puzzles of modern physics. They are predicted by Albert Einsteins general theory of relativity, and their existence has been demonstrated indirectly (Joseph. H. Taylor and Russell A. Hulse received the Nobel Prize for this discovery in 1993), but until now it has never been possible to observe them directly. "Gravitational waves are elusive perturbations of space-time curvature, produced by material bodies when accelerating, and can be considered similar to electromagnetic waves emitted by charged particles when they are accelerating. They are difficult to detect, however, because of the fact that they are extremely weak perturbations and, at the best, we can only hope to register those produced by huge phenomenona, like the explosion of a supernova, the interaction between a neutron star and a black hole, or the fusion of two neutron stars belonging to a binary system", says Enzo Iarocci, president of Infn.

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...
