After re-analysing the plates, Dr Jain and Dr Singh concluded that they may have found axions that exist so fleetingly that they are not noticed by the modern electronic methods of particle detection that have replaced the use of photographic plates.

In July, a team from the European nuclear research facility at Cern, Geneva, announced the detection of a particle that fitted the description of the elusive Higgs.

Although physicists expected to find the particle someday, the actual detection is a highly significant discovery and completes an important stage in our understanding of what everything around is made.

Unlike the familiar three of length, breadth and height, these extra dimensions are curled up so tightly that they elude detection (though scientists are trying to prise them open in particle accelerators like the Large Hadron Collider near Geneva).
