In theory, the particles could reveal whether a reactor is building up plutonium for weapons. US energy experts are starting to take the idea seriously.
A team of young scientists paused their new physics searches to develop an innovative machine-learning tool, which is now helping them narrow in on a rare and messy decay of the Higgs boson.
Our visible universe is built mostly of glue, which generates roughly 98 percent of visible mass. Now, an experiment is gearing up to study novel manifestations of that glue.
