When a neutrino transforms a quark, a lepton is emitted.
Until now. A paper published last week in Nature Geoscience reports the results of recent work using neutrino detectors to quantify the radiogenic production of heat.
Swifter than a speeding neutrino they were not, but explanations for the news that subatomic particles apparently travelled faster than light have still arrived remarkably fast.
Called IceCube, it will work by detecting the flashes of light generated on those rare occasions when a neutrino hits one of the atoms in a molecule of water in the ice.
They wait for the flash of light that signals the rare occasion when a neutrino hits an ice molecule.
When a neutron inside an atom decays, it produces a proton, an electron, and a neutrino.
