...positive of the mechanism involved," say Drs. Arthur Neinhuis and Timothy Ley of the National Institutes of Health's Clinical Hematology Branch. The scientists speculate that, basically, the drug works by stripping genes of chemicals that have repressed their activity, allowing them to switch on again. The genes affected are those that produce hemoglobin for the developing fetus. These fetal genes turn off around birth as other genes take over to produce hemoglobin for human life outside the womb. Scientists still do not know why there are two sets of genes for making hemoglobin...

Though the sequence is as strong and beautifully detailed as the rest of Pakula's work, the events it depicts could have been narrated by Sophie in a few minutes, and should have been. (The film...
