  2. Er, my very rough understanding of this is they were looking for dark matter, but their detector had so much Xenon in it that some of it just happened to be Xenon-124, and it just happened to decay while they were watching. Still an unbelievably unlikely event, but made more possible by the fact that they had tons of Xenon hooked up to sensitive detectors.
