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.

An electrical trigger fires single, identical photons

Secure telecommunications networks and rapid information processing make much of modern life possible. To provide more secure, faster, and higher-performance information sharing than is currently possible, scientists and ...

Laser pulses create topological state in graphene

Discovering ways to control the topological aspects of quantum materials is an important research frontier because it can lead to desirable electrical and spin transport properties for future device technologies. Now MPSD ...

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.

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.
