An experiment at SLAC’s X-ray laser provides new insight into the ultrafast motions of a muscle protein in a basic biochemical reaction.
Image - This computerized rendering shows the 3-D structure of myoglobin, an oxygen-carrying protein found in many mammals’ muscles. The jagged green line represents a pulse of laser light that excites an iron atom (red sphere) at the core of the protein.

Scientists have assembled an exotic toolbox for experiments that tap into the brightest X-rays on the planet.
Image - This illustration shows a cutaway view of a type of sample system used at the Linac Coherent Light Source X-ray laser that jets samples in a superthin liquid or gel stream into its X-ray pulses. This system is known as a gas dynamic virtual nozzle
