Dark matter hunt: US LUX experiment reaches critical phase

The quest to find the most mysterious particles in the Universe is entering a critical phase, scientists say.

An experiment located in the bottom of a gold mine in South Dakota, US, could offer the best chance yet of detecting dark matter.

Early results from this detector, called LUX, confirmed it was the most powerful experiment of its kind.
