Scientists build a world in a grain of silicon

Abstract:
This new world is constructed of silicon -- the same material used for computer chips -- and the team's experience with nanotechnology and microfabrication techniques made it possible. Each of the 85 "neighborhoods" is a square chamber 100 micrometers to a side and 30 micrometers deep, providing enough elbow room for about 10,000 E. coli at most. Food and waste are introduced and removed through channels too narrow for the bacteria to pass through, and by varying the channels' flow rates, the team can make life easier or harder on a chamber's residents.
