The document discusses two studies: 1) A study that discovered a protein called Nova 1 that modulates gene expression involved in nervous system formation and structure, providing new insights into vertebrate brain evolution. 2) A study that found a link between obesity and insulin resistance, discovering that RNA splicing proteins are decreased in obese individuals, altering gene expression and predisposing them to insulin resistance and potential diabetes. The studies advance understanding of gene regulation and splicing in health and disease.
