These tiny green crystals, measuring just millionths of a meter, preserve the molecular structure and activity of Photosystem II, which carries out the oxygen-releasing process in photosynthesis. The chlorophyll-containing crystals, which have a boxlike structure, were studied at room temperature using ultrashort X-ray pulses at SLAC's Linac Coherent Light Source X-ray laser. The image was taken with a light microscope. | Photo by Jan Kern, Lawrence Berkeley National Laboratory.

This Friday, March 8, marks International Women's Day, and the recognition of women's achievements all over the world. At the Energy Department and each of the National Laboratories, some of the nation's top women scientists and engineers attend events to urge girls to open their minds to careers in science, technology, engineering and math (STEM). In this Febraury 2012 photo, a group of eighth grade girls were invited to Argonne National Laboratory to participate in events during the annual Introduce a Girl to Engineering Day. Division director Amanda Petford-Long and other Argonne mentors are pictured observing a trial run of race cars built by the eighth grade students. | Photo courtesy of George Joch/Argonne National Laboratory.
