Stem cells from human embryos are seen as the future of medicine, but a major ethical question surrounds the research: Should federally funded scientists be allowed to extract the cells from embryos, a process which destroys them? Current U.S. laws clearly say &ldquo;no.&rdquo;  Ian Wilmut, who made history when he cloned  Dolly the sheep in 1996, is now calling on scientists to inject human DNA into animal egg cells as a workaround to ethical and legal roadblocks. His commentary appears in Nature Reports Stem Cells, an online stem cell resource created by the journal Nature. ...
