Scientists at Switzerland's CERN research centre say they have found signs of a theoretical sub-atomic particle believed to be the basic building block of the universe.

The scientists conducted two separate experiments to try to locate the so-called God particle, wherein protons were fired into each other inside a 27Km long tunnel.

They have stopped short of calling it an official discovery, but the research has got the science world buzzing.
