A ghostly form bleeds through a painting, and another that could be a forgery. The National Gallery of Victoria is literally lined with secrets. Early attempts at solving these mysteries gave only a glimpse of what lay beneath the brushstrokes. It would take over 80 years in the makingand a giant leap in technology to uncover the hidden history. Catalyst goes behind the scenes at the National Gallery of Victoria to see how scientists from the Australian Synchrotronare revealing concealed gems with stunning clarity. In 2015, Catalyst took a remarkable road trip through Namibia in southern Africa, tracing the deepest roots of humanity’s family tree. From her mobile DNA lab, genomicist Professor Vanessa Hayes collected blood samples to search for the origins of modern society - the DNA evidence of when hunter-gatherers became farmers. We revisit this story to find out the results - what she discovered could rewrite human history.
