Hey, it's Flora, and you're listening to Science Friday.
Today we're bringing back a conversation with an absolute all-star, and it's a conversation I've thought about a lot since we recorded it, so I hope you enjoy it.
In nature, enzymes are the catalysts that make much of biology work.
They jumpstart chemical reactions that either wouldn't happen or would happen super slowly.
They do a lot of basic biological jobs, breaking down food, building other molecules, extracting energy.
But what if we could harness evolution to engineer designer enzymes that do other jobs, specific jobs that benefit us?
Putting that idea into practice changed the game for chemistry and earned Dr. Frances Arnold the Nobel Prize in 2018.
She called it directed evolution.
And this is really big.
Today, thousands of labs use these methods to coax enzymes into doing things no one had ever thought of.
Dr. Frances Arnold is a professor at Caltech, and we'll hear about where she sees this approach going in the future and her own personal evolutions.
