Researchers develop fast track way to discover how cells are regulated
Researchers at Huntsman Cancer Institute (HCI) at the University of Utah and a collaborator at the University of California at Santa Cruz report they have developed a unique computational approach to investigate a regulatory network for gene expression that is implicated in cell growth and development.

How preschool intervention leads to greater educational attainment
In the past decade, research on early intervention for high-risk children has expanded from a reliance on the main effects of the intervention to understanding the mechanisms of change.We investigated the contributions of five potential mechanisms on youths' educational and social well-being to explain the link between preschool and later well-being: cognitive advantage, family support, social adjustment, motivational advantage, and school support.
