The phylogeny of Prozac yogurt.
Christina Agapakis is a synthetic biologist and postdoctoral research fellow at UCLA who blogs about about biology, engineering, biological engineering, and biologically inspired engineering at Oscillator.
A few weeks ago, I saw a retweet that claimed “biohacking is easier than you think” with a link to a post on a blog accompanying a book called Massively Networked. The post included video of Tuur van Balen’s presentation at the NextNature power show a few months earlier. Van Balen is a designer whose work I’ve followed for a couple years now, and his most recent project imagines how synthetic biology might produce and deliver medicines in the future. He demonstrates—using homemade tools, equipment purchased on eBay, and online resources for finding and synthesizing DNA sequences—how someone could engineer a strain of bacteria to produce Prozac-laced yogurt. While he’s not actually making Prozac, his demonstration does show pretty accurately how someone could get DNA into a bacterium (without, of course, the frustrating months of troubleshooting that almost any experiment inevitably requires). I posted my own version of the story, writing that art projects like this can ask important questions about biological design.
The next day, my post was syndicated on the Huffington Post with a modified title that emphasized Prozac. Then a version appeared on Gizmodo, and it went on from there, spreading across the Internet. By the time its spread was complete, Van Balen, an artist interested in the implications of emerging biotechnologies, had mutated into a bioengineer at the forefront of synthetic biology research, creating Prozac yogurt in five days with just 860 base pairs of DNA. (If you were to actually make Prozac biologically, it would certainly take the action of many enzymes, each encoded by their own sequence of hundreds or thousands of base pairs).
How did an art piece, a design fiction that asks us to think critically about the possibilities opened up by synthetic biology, provoke an unskeptical acceptance of what bioengineering has made possible? Perhaps I should have been clearer in my post, or perhaps it’s the fault of sensationalized click-bait headlines. But I think it may be that we’ve become so accustomed to the hype surrounding the science of genes and DNA, so used to hearing about groundbreaking genetics, from the “gene for dry ear wax” to the “gene for Alzheimer’s” to the “gene for [common human behavior]” that we don’t think twice when we hear about mixing bacteria with the “gene for Prozac” to create antidepressant yogurt.
