Maureen Cavanaugh: As the saying goes, President Obama, "with a stroke of his pen," ushered in a new era in stem cell research. In March, the president lifted restrictions against the use of federal funding for embryonic stem cell research. That one act removed a huge barrier to what is a very promising area of medical science. Researchers have been telling us for several years now that stem cells may provide therapies and even cures for a variety of terrible illnesses including Parkinsons and Alzheimer's disease.
In this installment of our monthly series on Science and Ethics, we'll get an update on stem cell research - and hear about both the old and new ethical questions about that research.
