Researchers at the IceCube Neutrino Observatory in Antarctica have found seven signals that could potentially indicate tau neutrinos—which are famously hard to detect—from astrophysical objects.

About a trillion tiny particles called neutrinos pass through you every second. Created during the Big Bang, these “relic” neutrinos exist throughout the entire universe, but they can’t harm you. In ...

Add Yahoo as a preferred source to see more of our stories on Google. Neutrinos are the ultimate cosmic shapeshifters. They come in three “flavors”—electron, muon, and tau—and can morph from one type ...

Building experimental evidence suggests that the electron, muon and tau may feel different forces. When the tau lepton was discovered in the 1970s, it didn’t resolve any outstanding mysteries—it ...

For experimental physicists, the latest measurement of the muon is the best of times. For theorists there's still work to do. Colliding 300 billion muons over four years at the Fermi National ...

Millions of barely perceptible “ghost” particles called neutrinos fly through our bodies at every second. With almost zero mass and no charge, these particles don’t even so much as tickle us. They do, ...

Since the 1990s, physicists have pondered the tantalizing possibility of an exotic fourth type of neutrino, dubbed the “sterile” neutrino, that doesn’t interact with regular matter at all, apart from ...
