Neutrinos, sometimes nicknamed “ghost particles,” are among the most puzzling components of the universe. They pass straight through planets, buildings and even our bodies without leaving a trace, and trillions of them stream through humans every second. 

Because they barely interact with anything, scientists struggle to study them. However, understanding how they behave could help explain how the universe is structured and where its matter comes from.

The new data suggests JUNO is working exactly as planned and is already measuring neutrino behavior with more accuracy than all previous experiments combined, according to scientists at the University of Mainz in Germany, who collaborate on the project. 

The results put researchers closer to answering a major outstanding question in physics: the order of neutrino masses, which determines how these particles transform from one type into another as they travel .

The observatory itself is enormous: a 20,000-ton spherical detector buried deep under a mountain in southern China. It took ten years to build and cost more than $350 million. It was designed specifically to track the subtle changes neutrinos undergo as they move, which earlier experiments could not measure clearly.

Although located in China, JUNO is a global effort involving more than 700 researchers from 17 countries, including the United States , Germany, Italy, France and Russia.

“Achieving such precision within only two months of operation shows that JUNO is performing exactly as designed,” project leader Yifang Wang said. 

He said the detector is now positioned to answer questions that have puzzled scientists for decades and to search for entirely new physics beyond current theories.

Field teams began with standard botanical documentation, which included mapping the vine’s footprint, photographing growth form, and recording dimensions such as height, basal diameter, and girth. Following this, researchers turned to ring analysis.

Deputy Director of the Institute of Fruit Trees at the Chinese Academy of Agricultural Sciences, Dr Wang Haibo, told Guinness World Records that finding a wild grapevine over four centuries old at an altitude of 2,400 metres is a testament to nature’s patience and life’s resilience.

Guinness World Records certified the vine in September, after reviewing the scientific documentation, site details, and methodological notes, and confirming it to be 416 years old.
