The image describes a Chinese fairy tale, the “Magpie Bridge Meeting”. On the night of the lunar Double-Seventh Festival, magpies form a bridge across the Milky Way to reunite two separated lovers: The Cowherd and the Weaver Girl. Ddx3xb phase separation (Magpie bridge) promoted the degradation of maternal RNA (overcoming the obstruction of the Milky Way) and the activation of zygotic genes (the silk spun by the Cowherd and Weaver Girl after reunion).See page 715–728 by Boyang Shi et al. for details.
