Story summary

Chinese scientists have made a groundbreaking leap by creating viable mice with two fathers, a feat once thought impossible. Under the leadership of Zhi-kun Li, the team harnessed CRISPR/Cas9 to modify 20 imprinted genes, enabling some mice to thrive into adulthood. Though these mice face sterility and shorter lifespans, the research paves the way for new insights into congenital disorders and regenerative medicine.
