A failure of ethical imagination

Margaret Somerville
Some scientists cannot understand that our most treasured values are at stake in research on human embryos.
Human embryo stem cell (hESC) research has been making front-page news in both the United States and Canada for some time. This spring U.S. President Barack Obama lifted restrictions on this research so pluripotent stem cells, which can form all of the tissues and organs in the human body, can now be taken from embryos "left over" from in vitro fertilization. This kills the embryos.
