The Spin

Narrative A

This is a significant step forward in reproductive science, potentially offering new paths for endangered species conservation and advancing regenerative medicine research. The successful modification of imprinting genes shows that genetic engineering can overcome barriers to same-sex reproduction.

Narrative B

The high failure rate, developmental abnormalities, and sterility in surviving mice raise serious concerns about the technique's viability. Resources would be better directed toward helping existing children in the healthcare system rather than pursuing controversial genetic engineering technologies.
