DNA isn’t just a building block of life—it can be a building block for other nano-size structures, too. These wonderfully intricate shapes are made by twisting and folding DNA into complex shapes using a newly developed technique, like a kind of advanced molecular DNA.
Molecular machines are nano-scale assemblers that construct themselves and their surroundings into ever more complex structures. Sometimes dubbed "nanotech" in the media, these devices are promising — but also widely misunderstood. Here's what separates the science fact from science fiction.
