"We are trying to investigate what could be behind the accelerated expansion of the universe," Katrin Heitmann, one of the Los Alamos scientists tells "Our technique is based on data, and can be used to evaluate different models." (

ceCube's size makes it ideal for understanding completely new physical phenomena, says Bill Louis, a physicist at Los Alamos National Laboratory in New Mexico and co-spokesman for the neutrino experiment MiniBooNE.

As neutrinos travel, they may oscillate between three known types — electron, muon and tau — but results published last October suggest that MiniBooNE may have observed muon anti­neutrinos turning into a fourth type, called a sterile neutrino. (Full Story
