Last month, Bloomberg reported on what seems to be the first child born following a new kind of genome-wide screening. Four embryos were screened, and the embryo selected for implantation was the one given the best genetic odds of avoiding heart disease, diabetes, cancer, and schizophrenia in adulthood. The news has been met with some concerns about the degree of control we may now have over future generations.

In late May, an international organization eliminated a 40-year prohibition against human embryo research beyond 14 days. The legal and scientific consequences will vary around the world.
