A bit of serendipity while carrying out a routine calibration led a researcher at Lawrence Berkeley National Laboratory's (Berkeley Lab) BELLA Center to discover a new method to measure the pressure of supersonic nozzles. ...

New 'soft' motor made from artificial muscles

The electrostatic motor, used more than 200 years ago by Benjamin Franklin to rotisserie a turkey, is making a comeback in a promising new design for motors that is light, soft, and operates without external electronic controllers.

Light makes write for DNA information-storage device

Researchers have demonstrated a write-once-read-many-times information-storage device, made of DNA embedded with silver nanoparticles, that uses ultraviolet light to encode data.

Certain doped-oxide ceramics resist Ohm's Law

For months, Anthony West could hardly believe what he and his colleagues were seeing in the lab -- or the only explanation for the unexpected phenomena that seemed to make sense.

Gallium nitride transistor could replace silicon
