Who says science and art need to be opposites? Thereâs plenty of room for overlap in the two fields, and why shouldnât they be — theyâre both creative pursuits. And, when it comes to this latest science/art merger, thereâs really no better word than “creative.” The only other phrase that comes to mind is “this is amazing but humans are getting too goddamn smart for their own good.”
Scientists at Caltech have just recreated a tiny version of Van Goghâs Starry Night by folding DNA molecules. The creation marks the first time this technique, known as âDNA origami,â has successfully scaled up to build large number of DNA-based devices on computer chips. The Caltech team published their findings in Nature.
The “origami” name may make this work sound artsy, but there are real scientific implications for DNA origami, and itâs part of broader conversation that believes molecules to be âthe devices of the futureââas Caltechâs Paul Rothemund told Gizmodo. âBut how do you connect them? How do you wire them up into larger circuits? How do you do anything with them? You need an interface between the molecular and the macroscopic world, and thatâs what this is.â
Rothemund co-authored the Nature article and is regarded as a DNA origami pioneer. Heâs been folding DNA into interesting shapes for a decade now, and his minuscule artworkâwhich has included smiley faces (see above), snowflakes, and a map of the Western hemisphereâwas displayed at New Yorkâs MoMA in 2008.
The methodology behind DNA origami is, of course, incredibly complex. But, in short, Rothemund and Caltech postdoc Ashwin Gopinath developed a way of folding DNA and then tuned injected fluorescent molecules to specific wavelengths, leading to patterns of âhotâ and âcoldâ spots that can be fashioned into images. Gopinath had just watched the âVincent and the Doctorâ episode of Dr. Who and was inspired to design the test around an image of Starry Nightâknowing that successfully capturing the painting’s complexity would assuredly demonstrate DNA origamiâs power and potential. And voila! Here we have it.
DNA origami may have resulted in the most impressive recreation of Van Goghâs masterpiece thus far, but it is one of several similar recent pursuits, like this rendering of Starry Night in a bowl of water, and this one that uses a handful of bacteria-infested petri dishes. Which one do you like most? Let us know in the comments.
