What does your hair say about you?
I’ve always found the world of forensics fascinating. Despite a seemingly rocksolid alibi, a single strand of hair that shouldn’t be there can speak otherwise. The ‘Stranger Visions’ piece by Heather Dewey Hagborg at the fascinating Big Bang Data exhibition in Somerset House highlighted how minute physical fragments of our presence are constantly being unwittingly left as genetic debris, in the form of skin, saliva and hair. The piece exposed the extent to how vulnerable, detectable and accountable we all really are. The artist collected used souvenirs from members of New York City public, unknown and anonymous to her, who had randomly discarded articles such as cigarette butts, chewing gum and strands of hair. Through the use of DNA phenotyping (predicting an individuals’ physical traits based upon their genetic makeup) in a molecular biology lab, she was able to make a 3D portrait of close replication to the individual to which the genes belonged.
In the world of forensics, DNA phenotyping can be critically utilised in tests such as ‘IrisPlex’ where DNA collected can be analysed to ascertain eye colour of the suspect. However on the flip side, do we want the data our bodies’ emit ending up in the wrong hands, identities being cloned and privacy encroached? There is also a terrifying possibility for the potential of genetic surveillance. With developing forensic technology, can ethics and individual autonomy keep up?
