Scientists with the Karlsruhe Tritium Neutrino experiment, or KATRIN, said Monday they'll be taking measurements "well into the next decade" and hope to produce "high-impact results."

Researchers say determining the mass of neutrinos is one of the most important open questions in particle physics and will help scientists better understand the history of the universe.
