State involvement will create a vast bioethical quagmire. Even if everyone magically agrees that improving a child's memory is as valid as avoiding dyslexia, there will still be things taxpayers aren't ready to pay for--genes of unproven benefit, say, or alterations whose downsides may exceed the upside. (The tendency of genes to have more than one effect--pleiotropy-- seems to be the rule, not the exception.) The question will be which techniques are beyond the pale. The answers will change as knowledge advances, but the arguments will never...

Says Marc Rayman of Jet Propulsion Laboratory, DS1's chief engineer: "We have an unproven propulsion system, powered by an unproven solar array, commanded by an unproven navigation system...
...explosive as it was last year. Linden, who had the second-most passing yards and touchdowns in school history last season, had three touchdown passes against Columbia in last year's opener. He has mastered Murphy's offense, and Harvard hopes that translates into continued success despite unproven receivers...
