All of which is the basis of the new book I’m reading, The Code Breaker, by Walter Isaacson. A bit of a mix of People Magazine and Scientific American. The pure science is fascinating. The competition to commercialize and the patent wars, not so much. The bio-ethics or gene editing and designer babies stuff mind bending.

I think the last few chapters could be the best part—where RNA meets Covid 19. We’ll soon find out.
