COVER False-color scanning electron microscopy image of a cluster of L-cystine crystals captured on a porous fi ltration membrane after growth in the presence of a growth inhibitor. The tapered needles result from binding of the inhibitor at the crystal surface, which reduces the crystal growth rate and the crystal size (the cluster is ~95 μm across). This suggests that inhibitors might be designed to prevent or limit the formation of L-cystine kidney stones. See page 337. Image: Zhihua An and Timothy G. Bromage/New York University
