The other half of the story: effect size analysis in quantitative research.

Statistical significance testing is the cornerstone of quantitative research, but studies that fail to report measures of effect size are potentially missing a robust part of the analysis. We provide a rationale for why effect size measures should be included in quantitative discipline-based education research. Examples from both biological and educational research demonstrate the utility of effect size for evaluating practical significance.

An essential role for cortactin in the modulation of the potassium channel Kv1.2.

Ion channels are key determinants of membrane excitability. The actin cytoskeleton has a central role in morphology, migration, intracellular transport, and signaling. In this article, we show that the actin-binding protein cortactin regulates the potassium channel Kv1.
