To test their algorithm, the researchers designed and built a system of 'smart pebbles' — cubes about 10 millimeters to an edge, with processors and magnets built in.

Self-sculpting sand

New algorithms could enable heaps of ‘smart sand’ that can assume any shape, allowing spontaneous formation of new tools or duplication of broken mechanical parts.

Testing unbuilt chips

A new software-simulation system promises much more accurate evaluation of promising — but potentially fault-ridden — multicore-chip designs.

A new test chip developed by Vladimir Stojanovic, Rajeev Ram and their colleagues, which monolithically integrates electrical and optical components and was produced on an existing IBM manufacturing line.

Microchips’ optical future

To keep energy consumption under control, future chips may need to move data using light instead of electricity — and the technical expertise to build them may reside in the United States.
