What The If?

Scientists just used artificial intelligence to design the world's first AI-generated viruses capable of hunting down and killing drug-resistant strains of E. coli. These bacteriophages look like tiny alien pineapples with syringes that stab bacterial cells, and they're just the beginning of AI-created life. From Matt's dream of dish-cleaning bacteria that won't eat you (hopefully) to the accidental discovery that trying to make super purple petunias actually created white flowers instead, this episode explores what the if happens when computers start writing genetic code. Discover why we're running out of antibiotics, how a virus with only 11 genes works, and why your future dish soap bottle might say "now with AI inside." Plus, learn about the scientist who tried to engineer the most purple petunias ever and accidentally won a Nobel Prize instead.
