In recent years there have been quantum leaps in the development of calculational technology for field theory amplitudes, partly captured by the buzzwords in the title of this talk. Interestingly, most of these developments are rooted within field theory ideas of the sixties which centered around the 'analytic S-matrix'. This line of thought led to the birth of string theory with Veneziano's amplitude. It therefore seems a natural question if these recent field theory ideas can be found within the frame-work of string theory amplitudes. On the basis of three examples, I will argue that this is not only natural but profitable.
