The Viruses That Could Cure Cancer (And Maybe Wipe Out Humanity)

Gideon Lichfield and Lauren Goode talk to Andrew Hessel, a scientist, writer and entrepreneur who is working to push forward the field of synthetic biology — the science of genetically modifying organisms for everything from vaccines to food production. They discuss how modified viruses can be used to treat a range of cancers, and the wide ranging, science-fiction-like implications of the field.
