Journalist Stephen Hall discusses a surprising new finding concerning in vitro fertilization and the screening of embryos. In his cover story for New York Magazine, "A New Last Chance", Hall explores how our understanding around what counts as a "viable" embryo is changing, what this means for the many "abnormal" embryos doctors have discarded and how this may provide more opportunities for women hoping to become mothers.
