‘Ghostly’ neutrinos provide new path to study protons
Neutrinos are one of the most abundant particles in our universe, but they are notoriously difficult to detect and study: they don't have an electrical…

IceCube neutrinos give us first glimpse into the inner depths of an active galaxy
For the first time, an international team of scientists have found evidence of high-energy neutrino emission from NGC 1068, also known as Messier 77, an…
How ghostly neutrinos could explain the universe’s matter mystery
The answer to one of the greatest mysteries of the universe may come down to one of the smallest, and spookiest, particles.
Matter is common in…
Particle Hunters Can Spend a Lifetime Searching for Answers
IceCube is an example of how big science, and particularly particle physics, now often works on generational time scales. Getting from the idea of IceCube to…
How neutrinos could ensure a submarine’s nuclear fuel isn’t weaponized
Nuclear submarines might provide rogue nations with a path to nuclear weapons. But neutrinos could help reveal attempts to go from boats to bombs.…
High-energy neutrinos may come from black holes ripping apart stars
When a star gets too close to a black hole, sparks fly. And, potentially, so do subatomic particles called neutrinos.
A dramatic light show…
The Great Neutrino Mystery Could Point to Missing Particles
In 1993, deep underground at Los Alamos National Laboratory in New Mexico, a few flashes of light inside a bus-size tank of oil kicked off a detective story…
The already tiny neutrino’s maximum possible mass has shrunk even further
To understand neutrinos, it pays to be small-minded.
The subatomic particles are so lightweight, they’re almost massless. They’re a tiny fraction of…
In a first, neutrinos were caught interacting at the Large Hadron Collider
The Large Hadron Collider’s claim to fame is its ability to unveil elusive subatomic particles. But there’s one class of particle that it had never…
