This week in research news: teasing out genetic clues across the skeleton, a "missing mutation" in infant epilepsy, and studying soy-based baby formulas.
Bone mineral accrual doesn't keep pace with height growth prior to adolescence, according to a national study. After a teenager reaches adult height, bone mineral accrual tends to play catch-up: Roughly 10 percent of bone mass continues to accumulate after height growth is complete. The study findings also suggest that bone growth is site-specific, with bone mineral density developing at different rates in different parts of the skeleton.
