Fast Bit-Switching in a Thermal Memory

Fast Bit-Switching in a Thermal Memory

August 15, 2014

Theorists propose a “thermal” memory—one based on temperature, rather than voltage—that could switch from zero to one faster than other designs.

Bargaining for a Better Helium Deal

Bargaining for a Better Helium Deal

July 17, 2014

A pilot program jointly run by the APS hopes to use the collective bargaining power of many researchers to negotiate a better price for liquid helium.
