Happy Birthday, Frances Arnold! You're the only person we know who can evolve enzymes faster than most of us can evolve our Netflix watchlists. Your groundbreaking work in directed evolution has not just earned you a rare triple crown—membership in The National Academy of Sciences, The National Academy of Engineering, and the Institute of Medicine—but also made biology labs everywhere jealous.Here's to another year filled with brilliant discoveries and enzyme adventures! May your birthday cake be perfectly evolved for maximum deliciousness—and may your celebrations mutate into something truly unforgettable. Cheers to science's favorite evolutionary pioneer!
