Physicists discovered neutrinos 70 years ago. The ghostly particles still have secrets to tell

Scientists have achieved groundbreaking advances in neutrino detection, using mechanical sensors to spot nuclear decays for the first time and creating ultra-sensitive microcalorimeter arrays that established the most stringent limits on electron neutrino mass. These innovations also enabled direct observation of coherent elastic antineutrino-nucleus scattering, opening new pathways to unlock the remaining mysteries of these elusive particles.
