“A mysterious sub-atomic particle has been revealed that does not to fit any of the models currently used by physicists.

The discovery either suggests that a new family of molecule-like sub-atomic particles exists, or that theorists must substantially re-think their theory of the masses of sub-atomic particles.

‘If the molecular interpretation is correct, then it would be one of the first compelling cases for a new type of matter – it opens up a whole new realm of study,’ says …one of the team involved in confirming the existence of the new particle. There would also probably be more molecule-like particles to find, he adds.” —New Scientist
