Ten years ago this week, Jennifer Doudna and Emmanuelle Charpentier discovered how to use RNA to program CRISPR-Cas9 to precision edit DNA—and the possibilities for improving the health of humans, animals, and plants have been unfolding at a remarkable pace.
What is CRISPR? Short for “Clustered Regularly Interspaced Short Palindromic Repeat,” CRISPR describes repetitive DNA sequences that bacteria store naturally to “remember” the DNA of viruses that attack them. Cas9 is a natural mechanism by which bacteria defend themselves by cutting a piece of DNA from the virus.
On June 28, 2012, Jennifer Doudna and Emmanuelle Charpentier published their discovery in Science. They shared the Nobel Prize in 2020.

CRISPR-Cas9 unlocks a range of medical applications—especially in the exciting new field of gene therapy, with clinical trials underway for blood disorders, cancers, inherited eye disease, diabetes, infectious disease, inflammatory disease, and protein-folding disorders, according to the Innovative Genomics Institute.
Just a few examples include:
CRISPR-Cas9 can also improve the health of animals, and facilitate a One Health approach to animals, humans, and the environment. Examples include:
And CRISPR-Cas9 can dramatically speed up plant breeding, which has led to developments like:
