Portrait Sculptures From Genetic Material 32

rogue-girl writes "Artist Heather Dewey-Hagborg showcases portrait sculptures from genetic material collected in public spaces. DNA extraction and processing are done in a DIYbio-compliant fashion at the DIYbio hackerspace Genspace in Brooklyn, the collected information is then given as input to a 3D printer. The software developed and used for this project is awkwardly dubbed 'friendware', that is it is neither open nor closed, but only available to friends. Reconstructing faces from DNA is not new: scientists already successfully reconstructed Neanderthal man's face from ancient DNA back in 2008. At first sight, the artist's project may seem fun and quite impressive as high-voltage science proves once more feasible at home, but all the data one can have access to from totally banal samples leaves open worrying perspectives about how easy it is to use DNA collected in public spaces for "fingerprinting" people against their will and without their consent."

  • I notice that they took these samples from cigarettes and chewing gum. Seems to me that if you leave something like that in a public space, there's no privacy concern.

    Lifting off of a used glass/hair follicle/sweaty towel at the gym/etc. would be a bit more worrying.

    But since a person's features are more than their base structure, it's probably not too big an issue anyway. It's highly unlikely that they'll be able to model exactly what a person looks like at their current age/health.

    This method could definitely help with missing persons issues though, as an adult model could be created based on a child's DNA that would look "similar" to the actual person.

    I'd be interested if two runs on DNA samples from the same person would turn out faces that look the same....

    I don't believe this so called "artist", and think that she is, in reality, nothing more than a self-promoting B.S. artist.

    DNA testing isn't cheap under the best of conditions, when you can take a blood sample in an office, and in the case of recovering genetic traces from discarded cigarette butts, etc. that are full of environmental contamination, the obstacles to acquiring a usable sample are formidable. I would bet that this "artist" cannot provide any laboratory reports or paid receipts from an accredited DNA laboratory to back up her outlandish claims of having extracted and analyzed these supposed genetic samples.

    Moreover, her claim to have written custom software that can reconstruct facial features, and actually synthesize a 3D face from the results of testing two or three genetic characteristics is laughable on its face.

    I can only assume that she has personal connections with the media outlets that are promoting her fake art, or she has paid a PR firm to plant these ridiculous stories in willing press outlets.

    Obvious practical joke. Not even close to being believable.

    Other than single-gene diseases, we have a very poor idea of which QTLs influence which traits (assuming QTLs even exist). With billions of possibilities among all the alleles and haplotypes, one can make up whatever combination of DNA letters they want and "prove" its association with a given phenotype through a low p-value. One can also use "penetrance" to explain away deviations. One can build whatever Bayesian models they want, building a house of cards that will collapse very quickly as new data is introduced which contradicts the old. I was going to do my dissertation on statistical genetics, but the more I learned about it, the more I learned how intractable the problem is. I did my dissertation on a different topic.
