Quite the bit of science going on - from Nature:
Single subatomic particle illuminates mysterious origins of cosmic rays
A single subatomic particle detected at the South Pole last September is helping to solve a major cosmic mystery: what creates electrically charged cosmic rays, the most energetic particles in nature.
Follow-up studies by more than a dozen observatories suggest that researchers have, for the first time, identified a distant galaxy as a source of high-energy neutrinos
This discovery could, in turn, help scientists pin down the still mysterious source of protons and atomic nuclei that arrive to Earth from outer space, collectively called cosmic rays. The same mechanisms that produce cosmic rays should also make high-energy neutrinos.
The Ice Cube observatory detected a muon which was the result of a Nutrino decay. They were able to secure data from other observatories to look for other subatomic particles from the same source and they found it. Some great science and detective work.
There is a fascinating book about the origins and the building of the Ice Cube Lab - read it about a year ago and really enjoyed it: The Telescope in the Ice: Inventing a New Astronomy at the South Pole
