Scientists have fashioned perhaps the most elaborate piece of DNA origami yet: a tiny three-dimensional vase just 70 nanometers tall. For 5 years, researchers have been able to create nanostructures out of DNA, but until now most of the shapes have been fairly boring, like boxes or polygons, because they needed to be folded around a grid of DNA pegs or “pixels.” In their paper published online today in Science, researchers describe a new origami technique, in which they begin by forming rings of different radii with DNA strands.
