Part I — The story
The story
Jennifer Doudna, with Emmanuelle Charpentier, co-developed CRISPR-Cas9 — a revolutionary tool that lets scientists edit DNA with unprecedented precision, ease, and low cost, effectively giving humanity the ability to rewrite the genetic code of living things. The breakthrough, which won them the 2020 Nobel Prize in Chemistry, is transforming medicine, agriculture, and biology, opening the possibility of curing genetic diseases and much more.
Doudna's work is a study not only in scientific discovery but in responsibility. Recognising that a technology so powerful could be misused — to edit human embryos, for instance — she became a leading voice urging the scientific community to confront the profound ethical questions CRISPR raises, rather than racing ahead heedlessly. She is a study in a foundational, enabling breakthrough that empowers countless others, and in the responsibility that must accompany transformative power.
Part II — The playbook
The playbook
Build the enabling tool
CRISPR empowers countless other scientists — a foundational platform breakthrough.
Confront the responsibility of power
Doudna led the ethical conversation CRISPR demands.
Make the powerful simple and cheap
CRISPR's impact came from being precise, easy and low-cost.
In their words
The power to control our species' genetic future is awesome and terrifying.
Scientists have a responsibility to engage with the public about their work.
Nature is a far better engineer than we are.
