Spinning the light: The world's smallest optical gyroscope

Engineers create an optical gyroscope smaller than a grain of rice.

Study breaks Förster resonant energy transfer (FRET) distance limit

Using engineered nanocomposite structures called metamaterials, a research team reports the ability to measure a significant increase in the energy transfer between molecules.

Nanotubes may give the world better batteries

Scientists' method quenches lithium metal dendrites in batteries that charge faster, last longer.

Light-bending tech shrinks kilometers-long radiation system to millimeter scale

The DESY accelerator facility in Hamburg, Germany, goes on for miles to host a particle making kilometer-long laps at almost the speed of light. Now researchers have shrunk such a facility to the size of a computer chip.
