Scientists and engineers have reported the direct detection of cyclotron radiation from individual electrons. They used a specially developed spectroscopic method that allowed them to measure the energy of electrons, one single electron at a time. The method provides a new way to potentially measure the mass of the neutrino, a subatomic particle that weighs at most two-billionths of a proton.
