In political speechifying, what goes unsaid can count just as much as what gets blurted out. So when President Bush blatantly ignored the topic of embryonic stem-cell research in his recent State of the Union address, it's no surprise that advocates considered his silence potentially significant.
Launching into a discussion of medical research with his stock catchphrase about preserving a "culture of life," the president announced that "we should all be able to agree on some clear standards," and then declared, "I will work with Congress to ensure that human embryos are not created for experimentation or grown for body parts and that human life is never bought or sold as a commodity."
