Since the 1960s, it's largely been assumed that most of the DNA in the human genome was junk. It didn't encode proteins—the main activity of our genes— so it was assumed to serve no purpose. But Assistant Professor of Biology Nelson Lau is among a new generation of scientists questioning that hypothesis. His findings suggest we've been wrong about junk DNA and it may be time for a reappraisal. If we want to understand how our bodies work, we need to start picking through our genetic garbage.
