In this week's social selection column, I look at three scientific papers that were extensively discussed on social media. First, is a study of biodiversity of arthropods in American homes, next, a report that suggests some of the most well-known fairytales date back thousands of years before the literary record, and finally, an investigation that suggests dogs view and understand facial expressions similar to humans. The full article was published on the Nature website.
