Telescope Array detects second-highest-energy cosmic ray ever

In 1991, the University of Utah Fly's Eye experiment detected the highest-energy cosmic ray ever observed. Later dubbed the Oh-My-God particle, the cosmic ray's energy shocked astrophysicists. Nothing in our galaxy had the ...

Physicists trap electrons in a 3D crystal for the first time

Electrons move through a conducting material like commuters at the height of Manhattan rush hour. The charged particles may jostle and bump against each other, but for the most part, they're unconcerned with other electrons ...

Mysterious antimatter observed falling down for first time

For the first time, scientists have observed antimatter particles—the mysterious twins of the visible matter all around us—falling downwards due to the effect of gravity, Europe's physics lab CERN announced on Wednesday.

Are Weyl fermions truly massless?

The behavior of electrons' mass within a solid has a significant impact on the flow of electronic and heat energy. Weyl semimetals have emerged as a fascinating class of materials with unique properties. Physical and chemical ...
