Working memory and attention are closely related concepts. Working memory is defined as the ability to control attention, and distraction (e.g., irrelevant emails or text messages). WMC is critical ...

Engineers made a pneumatic RAM chip using microfluidic valves instead of electronic transistors. The valves remain sealed against a pressure differential even when disconnected from an air supply line ...

A sheet of graphene sandwiched between electrolytes can host independently tunable proton and electron currents — setting the stage for a device that serves both computer-memory and logic functions.
