Misbehavin’ Meson: Perplexing particle flouts the rules
The discovery of what appears to be a new subatomic particle with bizarre properties is challenging theorists' understanding of how matter behaves.
- Physics
New pass at neutrino mass
The first experiment to create neutrinos in an accelerator and then beam them a long distance has found a long-awaited, new form of evidence that those fundamental particles weigh something.

Teleporting Matter’s Traits: Beaming information quantum-style
Physicists have transferred a quantum state from one atom to another by manipulating a mysterious, atom-to-atom quantum link called entanglement.
- Physics
Squashed spheres set a record for filling space
Modestly deformed spheres can stack with unexpected compactness.
