Courtesy of Zhen Yan’s lab, this image shows scientists sailing the endless ocean to decipher the mystery of chloroplast protein translocation. The vast ocean and icebergs stand for nature’s infinite enigmas, while the telescope-bearing figure represents the unwavering pursuit of knowledge. The structures on the two islands align with the key discoveries of the two papers, revealing the assembly, function, evolutionary conservation, and diversity of chloroplast protein import motors.
