Dear Reader, Check out some of today's top stories: scientists have crafted a trap for the dengue virus using a scaffold made from fragments of DNA; new findings might explain how childhood adversity paves the way for mood disorders during and after pregnancy; and the coronavirus pandemic has paused some climate research, which could threaten long-standing studies and imperil weather forecasts in the near term. Also, our main story explores an anti-aging gene that researchers say could lead to a new treatment in preventing Alzheimer's disease.
