Once viewed as reckless experimentation, germline gene editing is re-emerging as a serious scientific frontier. With base and prime editing now able to correct single-letter mutations with remarkable precision, researchers are beginning to demonstrate embryo edits that could one day eliminate devastating inherited diseases. The stakes, however, are profound: these are permanent, heritable changes passed to every future generation. This session examines the cutting edge of germline engineering—how far the science has advanced since CRISPR’s clumsy early days, what challenges remain around mosaicism and long-term safety, and where the ethical boundaries must be drawn. Should we consider germline editing only for rare, fatal conditions when no other reproductive options exist? Or is there a pathway to broader medical use under strict safeguards? Join leading scientists, ethicists, and policymakers as we debate whether rewriting inheritance is an act of compassion—or a step too far.
