How much do you know about your own DNA beyond that you have quite a bit of it in your brain and body? Do you know that you may leave traces of your DNA wherever you go whenever you leave anything that might contain some of your cells? Have you ever spit out chewing gum on the street or dropped a cigarette butt? You might want to think again! Recently I learned about artist Heather Dewey-Hagborg, who creates faces from DNA samples. Potentially, this could change the “face” of life in the world as we know it. Just think of the implications for investigating crimes to say nothing of tracking a person’s visits to specific locations. I also wonder what else might be discovered from memories filed on protein strands in the nucleus of cells that have a nucleus (cellular memory)? If you are interested in learning more about how Heather does this, here’s the link. I find it fascinating!
