China opens Juno lab to study neutrinos and tackle mass hierarchy problem

Summary: China has opened a new underground laboratory, Juno, in Kaiping, Guangdong province, to study neutrinos and address the mass hierarchy problem in particle physics. The facility, located 2,300 feet underground, cost $311 million and involves 750 scientists from 17 countries.

Juno aims to detect neutrinos from two nearby nuclear power plants, using the data to determine the heaviest and lightest neutrino states. This research is expected to take six years and could enhance understanding of fundamental physics and the universe.

Despite geopolitical tensions affecting international collaboration, some American scientists are optimistic about the project. They acknowledge challenges but emphasize the importance of scientific cooperation beyond political issues.
