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 technique based on optical microscopy that can be used to create images of atoms on the nanoscale. In particular, the new method allows the imaging of quantum dots in a semiconductor chip. Together with colleagues from the University of Bochum, scientists from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute reported the findings in the journal Nature Photonics.
Microscopes allow us to see structures that are otherwise invisible to the human eye. However, conventional optical microscopes cannot be used to image...
On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
