Erik Winfree, an assistant professor of computer science 
<javascript:loadBrain('Computer Science')> at The California Institute of 
Technology <javascript:loadBrain('Technology')>, has showed that it is 
possible to coax short strands of artificial DNA 
<javascript:loadBrain('DNA')> to spontaneously assemble into a Sierpinski 

The ability is a step toward embedding program 
<javascript:loadBrain('Program')>ming instructions in chemical processes 
and shows that there is no theoretical barrier to using molecular 
self-assembly to carry out any kind of computing and nanoscale fabrication, 
according to Winfree.
