Beyond the celebration of the 40-year-old lunar landing, the big science news this week came Thursday from a group of Chinese researchers who figured out how to grow healthy mice from mouse stem cells.
The breakthrough is a huge step for research into induced pluripotent, or iPS, stem cells, which is taking adult stem cells and converting them into embryonic stem cells. But the Chinese discovery is causing some to worry that we're a lot closer to human cloning than we should be.
This story in Friday's Los Angeles Times frames the debate well.
