What are the most significant quantum field theory discoveries in recent years?

[JohnB]

Quantum field theory discoveries continue to push the boundaries of our understanding of particle physics and fundamental forces. Some recent quantum field theory discoveries have challenged established models and opened up new possibilities. I'm particularly interested in how these quantum field theory discoveries might relate to quantum gravity research and string theory evidence. What do you think are the most important quantum field theory discoveries of the past decade? And how might they impact quantum foundations research?
