Metamaterials give sound a twist
The design allows researchers rotate a wave at precise angles so that it originates from the opposite direction, which could have implications for improving ultrasound imaging.

Catching Particle Fever
Interspersed with the plot of Particle Fever are artful explanatory animations and commentary by six articulate physicists. Through these characters, we learn that the Higgs is a stepping stone toward a deeper understanding of the universe.

Quantum timekeeping
Recent advances in controlling the quantum behavior of particles have inspired physicists to dream of a global clock that would tell the same time everywhere. It would be hundreds of times as accurate as current atomic clocks.

Making artificial muscles with a spin
Scientists have given ordinary fishing line and sewing thread a new twist. When coiled into tight corkscrews, the fibers can lift loads more than 100 times as heavy as those hefted by human muscles.

Einstein was wrong about spooky quantum entanglement
Einstein’s biggest blunder wasn’t about vacuum energy in space, but in confusing people about quantum entanglement.
