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.

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
