Free-electron lasers provide femtosecond X-ray pulses with a peak brilliance 10 billion times higher than any previously available X-ray source. such pulses could outrun key damage processes and allow structure determination without the need for crystallization and would be sufficient to image HIV, influenza and herpes, and further improvements may soon allow researchers to tackle the study of single proteins

it would be a huge improvement if you don’t need to grow crystals.
