Have you ever wondered how humans can see? Or how plants produce oxygen? Well, all these processes start with structural changes in molecules present in human eyes and plants. However, these structural changes happen at a very fast timescale which make them impossible to be seen by the naked human eye. We need a powerful imaging technique to see all these changes. X-ray diffraction – the technique which has helped us to understand the structure of our genetic material, DNA, – is an excellent way to understand the structures. Time-resolved X-ray diffraction imaging of these molecular dynamics will help us unravel fundamental mysteries nature.<\/p>\n\n\n\n\n\n\n\n
