Stargardt Disease (STGD), the leading cause of inherited childhood blindness, is primarily caused by mutations in the ABCA4 gene, yet the underlying mechanisms of photoreceptor degeneration remain elusive, partly due to limitations in existing animal disease models. To expand our understanding, we mutated the ABCA4 paralogues, abca4a and abca4b, in zebrafish, which has a cone-rich retina. Our study unveiled striking dysmorphology and elongation of cone outer segments in abca4a;abca4b double mutants, alongside reduced phagocytosis by the retinal pigmented epithelium.

As populations decline, the probability of inbreeding increases, along with the potential for negative effects on individual fitness. Detecting and characterizing runs of homozygosity (ROHs) is a popular strategy for assessing the extent of individual inbreeding present in a population and can also shed light on the genetic mechanisms contributing to inbreeding depression.

When the public figure is a politician, it is possible that partisan differences may also influence emotional, attentional, and behavioral responses to health news. We empirically examined public responses to Democrat John Fetterman's disclosure of his treatment for depression shortly after he was inducted into the United States Senate as the junior senator from Pennsylvania in 2023.
