The biggest tech revolution of the 21st Century isn't digital, it's biological. A breakthrough called CRISPR has given us unprecedented control over the basic building blocks of life. It opens the door to curing diseases, reshaping the biosphere, and designing our own children. Human Nature is a provocative exploration of CRISPR's far-reaching implications, through the eyes of the scientists who discovered it, the families it's affecting, and the bioengineers who are testing its limits.
