The Borexino experiment research team has succeeded in detecting neutrinos from the sun's second fusion process, the Carbon Nitrogen Oxygen cycle (CNO cycle) for the first time. This means that all of the theoretical predictions on how energy is generated within the sun have now also been experimentally verified. The findings are the result of years of efforts devoted to bringing the background sources in the energy range of the CNO neutrinos under control.

"We already know how to shoot electrons ballistically through one-dimensional nanowires made from these oxide materials," explains Levy. "What is different here is that we have changed the environment for the electrons, forcing them to weave left and right as they travel. This motion changes the properties of the electrons, giving rise to new behavior."

Developing safe and sustainable fuels for nuclear energy is an integral part of Los Alamos National Laboratory's energy security mission.

Bringing huge amounts of protons up to speed in the shortest distance in fractions of a second -- that's what laser acceleration technology, greatly improved in recent years, can do. An international research team from the GSI Helmholtzzentrum für Schwerionenforschung and the Helmholtz Institute Jena, a branch of GSI, in collaboration with the Lawrence Livermore National Laboratory, USA, has succeeded in using protons accelerated with the GSI high-power laser PHELIX to split other nuclei and to analyze them.

Potential applications of research conducted at the University of São Paulo include high-precision metrology and information encoding.
