    Ethics of humanized mice The recent stories “Human cells rev up mouse brains” (SN: 4/6/13, p. 16) and “Of mice and man” (SN: 3/23/13, p. 22) drove home to me that human-animal hybrids are now reality. In science fiction stories with such hybrids, a big part of the plot is the resultant ethical gray area: […]
