An interdisciplinary collaboration of physicists, chemists, and materials scientists lead by the and the has invented a new ultrasensitive molecular sensing technique to monitor a nuclear decay reaction. With it, the collaboration could solve a decadeslong mystery about the nature of neutrino particles and address some of the fundamental questions about our universe.Neutrinos are subatomic particles that have no electrical charge and extremely small mass — some even think they could have no mass.
