Memory’s Role in Social Anxiety, The First Synthetic Self-Replicating Genome, and Penguins Can Call Underwater

Learn about new research into how social anxiety works in the brain; how scientists developed the first synthetic self-replicating genome; and the adorable sounds penguins make underwater.
