The breakthrough science of synthetic biology and its potential for helping solve humanity's existential challenges, from climate change to the health and feeding of millions, and fighting the next viral outbreak before it becomes a global pandemic.Synthetic biology is the promising and controversial technology platform that combines biology and artificial intelligence, opening up the potential to program biological systems much as we program computers. Synthetic biology enables us not just to read and edit DNA – the technique of CRISPR - but also write it. Rather than life being “a beautiful game of chance”, synthetic biology creates the potential to control our genetic destiny, to say “no” to bad genes and build a veritable genetic app store for downloading and adding new capabilities into any cell, microbe, plant, or animal. Amy Webb and Andrew Hessel’s riveting stories include: the work of scientists to develop plants that can be grown in sprawling indoor farms capable of feedin
