How do we search for alien life if it’s nothing like the life that we know? At TEDxUIUC Christoph Adami shows how he uses his research into artificial life — self-replicating computer programs — to find a signature, a ‘biomarker,’ that is free of our preconceptions of what life is. (Recorded at TEDxUIUC, July 2011, in Urbana-Champaign, Illinois. Duration: 18:52.)
