Powledge discusses the week's other major scientific conference (the one that isn't focused on climate change), the International Summit on Human Gene Editing, where scientists debated the ethics of their work: "At its conclusion, the scientists who organized the gene-editing summit came out against germline editing – editing human eggs and sperm – if its intent is to produce a gene-altered baby. But what they propose is really only a temporary prohibition."
