"Heating Up the Race to Weigh the Mysterious Neutrino"
Physicists are racing to weigh neutrinos, the mysterious elementary particles, with the KATRIN detector in Germany currently leading the effort. Alternative approaches are being developed at various laboratories, with the goal of building scaled-up versions to compete with or improve upon KATRIN. These efforts are driven by the need to measure the tiny masses of neutrinos, which could potentially challenge current estimates from cosmology. Techniques such as electron capture and the Project 8 experiment are being explored to achieve greater sensitivity in neutrino mass measurements.
