Dark matter is the mysterious substance that makes up roughly a quarter of the Universe. There is strong indirect evidence for its existence from measurements of cosmic primordial radiation, anomalies in the radial dependence of galactic rotational curves and gravitational lensing. Despite its apparently pivotal role in the Universe the physical origin of dark matter remains unknown. Scientists suspect that it is made of unseen particles that neither reflect nor absorb light, but are able to exert gravity. Two theoretical physicists at the University of York, UK, have a new candidate: a recently-discovered bosonic particle, the d*(2380) hexaquark.
