Hype springs eternal in medicine, but lately the horizon of new possibility seems almost blindingly bright. “I’ve been running my research lab for almost 30 years,” says Jennifer Doudna, a biochemist at the University of California, Berkeley. “And I can say that throughout that period of time, I’ve just never experienced what we’re seeing over just the last five years.”
A Nobel laureate, Doudna is known primarily for Crispr, the gene-editing Swiss Army knife that has been called “a word processor” for the human genome and that she herself describes as “a technology that literally enables the rewriting of the code of life.” The work for which Doudna shared the Nobel Prize was published more than a decade ago, in 2012, opening up what seemed like an almost limitless horizon for Crispr-powered therapies and cures. But surveying the recent landscape of scientific breakthroughs, she says the last half-decade has been more remarkable still: “I think we’re at an extraordinary time of accelerating discoveries.”
The miracle of the vaccines wasn’t just about lives saved from Covid. As the first of their kind to be approved by the Food and Drug Administration, they brought with them a very long list of potential future mRNA applications: H.I.V., tuberculosis, Zika, respiratory syncytial virus (R.S.V.), cancers of various and brutal kinds.
