Previous studies suggested that emotional expressions related to morality (e.g., “hate” or “disgust”) increase the diffusion of political messages. A pre-registered direct replication and meta-analysis confirms this “moral contagion” effect. In PNAS Nexus: https://ow.ly/CPpx50Xq2G7

The triangle weaver spider has a spring-loaded web, which it holds taut with its body until prey lands. The spider’s genome has an expanded set of MaSp2 genes that encode silk proteins with high concentrations of the amino acid proline. In PNAS Nexus: https://ow.ly/8B7K50Xpuq0
