The short film Diamond Light Source: Science in its Purest Form reports on the research by three scientists working at the facility. One scientist is using the synchrotron to study martian meteors in details so that they can correlate the rock material composition to data measured by satellites in orbit around Mars. A second research is studying catalysts to understand how they promote chemical reactions. A third scientist is studying protein crystals to better understand how they work in the body and to make better drugs.
