The announcement came in June. Berkeley Extension, the continuing education arm of UC Berkeley, was offering its first-ever introductory course—CRISPR Genome Editing: From Biology to Technology—on the revolutionary new tool that allows scientists to make precise edits in the genome. A lab and lecture course on CRISPR for anyone who has the interest (and money) to enroll? What a crazy idea. It seemed a bit like offering a workshop on how to enrich plutonium.
One of biology’s wilder facts is that we’re all family. You and me, sure, but also me and a mushroom. Triceratops shared genes with you. So does the virus that makes you cough, and a rosebush. Bacteria left us on the tree of life around 2.7 billion years ago, but the wet world they came from is still ours: One code runs all of life. The same proteins that imprint memories in your neurons, for example, do so in octopi, ravens, and sea slugs. This genetic conservation means tricks from one species can be hijacked. If you stick a jellyfish gene in a monkey, it’ll glow green.
Brave New World author Aldous Huxley came to Berkeley (his son’s alma mater) in 1962 and delivered a speech on campus entitled “The Ultimate Revolution.” It ended as follows: “Our business is to be aware of what is happening, and then to use our imagination to see what might happen, how this might be abused, and then, if possible, to see that the enormous powers which we now possess thanks to these scientific and technological advances be used for the benefit of human beings and not for their degradation.”
