An Italian team on Wednesday renewed its claim to have discovered evidence for the existence of dark matter, the invisible material that makes up the bulk of the universe.

"This is a Nobel Prize-winning result if it is proved," said physicist Richard Gaitskell of Brown University, who was not involved in the research. (source: latimes.com)
