timing. We have used a combination of live imaging, gene expression analysis, and physical theory to explore the organization and function of the segmentation clock, the synchronized oscillating gene network that underlies the dynamics of somitogenesis. I will discuss new experimental results identifying somitogenesis period mutants, and corresponding theoretical approaches that explain the col...

Kidney stones develop more frequently in individuals with a family history of kidney stones than in those without a family history; however, little information is available regarding whether the increased risk is attributable to genetic factors, environmental exposures, or some combination. In this report, the relation between family history and risk of kidney stone formation was studied in a c...
