Femtosecond X-ray pulses were used to obtain diffraction data on photosystem II, revealing conformational changes as the complex transitions from the dark S1 state to the double-pumped S3 state; the time-resolved serial femtosecond crystallography technique enables structural determination of protein conformations that are highly prone to traditional radiation damage.
