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.

Levitating objects with sound
Physicists have levitated millimeter-sized objects. Now, the objects can levitate and move in all directions.

History affects superfluid’s flow, study shows
The speed to stop the stirring motion can be slower than what was need to set the fluid spinning in the first place, which shows that what happens to the current state of the superatom depends on what it has already experienced.

Making it work, on paper and just maybe in practice
Last spring, Science News reported on the lack of progress by the main U.S. nuclear fusion effort. As the researchers still contend, laser-initiated fusion should work. It works on paper. But in practice, even a set of extremely powerful lasers failed to trigger the fusion of hydrogen nuclei and the concomitant chain reaction and release of net energy expected.
