New research in mice offers clues to factors that promote the development of a relatively common problem in humans, kidney stones (Clark JS et al. J Physiol. 10.1113/jphysiol.2007.143222 [published online ahead of print January 3, 2008]). Kidney stones are virtually absent in mice, and scientists at Beth Israel Deaconess Medical Center in Boston found that a key reason relates to how the body eliminates the chemical oxalate, which is common in food.
