Every engineer is going to have a bad day, but only an unlucky few will have a day so bad that it registers on a seismometer. We’ve always had a morbid fascination with engineering mega-failures, few ...

HIDA, Gifu Prefecture—The cutting-edge elementary particle observation facility here where it is hoped proton decay will be observed for the first time is on track to open in 2028 with a giant ...

Neutrinos: They have no electric charge, pass through matter like a ghost and are so light they were initially thought to have zero mass. These are just some of the traits that make them so difficult ...

A kilometre underground, in the depths of a Japanese mine, scientists have built a tank of ultra-pure water inside a gigantic cylinder full of photomultiplier tubes. This is the Super-Kamiokande ...

A large neutrino observatory in Japan has been heavily damaged by a freak accident. The Super-Kamiokande Observatory was designed to detect neutrinos by using a vast array of photomultiplier tubes.

Hyper-Kamiokande (HK or Hyper-K) project is the world-leading international scientific research project hosted by Japan aiming to elucidate the origin of matter and the Grand Unified Theory of ...

Physicists have made the first detection of a neutrino which had traveled all the way under Japan from their neutrino beamline at the J-PARC facility in Tokai village (about an hour north of Tokyo by ...

Only three or four supernovas happen in our galaxy every century. These are super-energetic events that release neutrinos at the speed of light. At the Super-Kamiokande detector in Japan, a new ...
