Particle breakdowns beat expectations
A fresh analysis of 2002 accelerator data finds a third instance of a type of breakdown of subatomic kaons that's not supposed to happen so often, suggesting that shadowy, hypothetical particles predicted by a theory called supersymmetry may be influencing kaon behavior.

A New Form of Water: Melting ice turns oddly dense
The density of a recently made film of water far exceeds that of ordinary water, suggesting that the film may be the first isolated sample of a proposed form of water thought to contribute to ordinary water's odd properties.

Quantum link connects light, ions
By proving experimentally for the first time that an atom and a photon can become entwined in a quantum embrace called entanglement, physicists took a step toward teleporting quantum characteristics from one atom to another.

Complexity by way of simplicity
Researchers have demonstrated a new way to simplify some intricate patterns whose extreme complexity has convinced theoretical physicist Stephen Wolfram that traditional science can't explain many important natural phenomena.
