...later admitted that he testified inaccurately about a key piece of evidence used at Cruz's trial. Cruz was freed in 1995, after 11 years in jail. Another man--a convicted murderer and rapist whose earlier confession to the murder had been ignored--was linked to the crime by DNA. After an independent investigation, seven prosecutors and law-enforcement officials were indicted on charges of fabricating and suppressing evidence to frame Cruz...
While Cruz was on death row, another young girl was killed. The man who confessed to that murder, Brian Dugan, was the man who had admitted killing Nicarico. When Marshall and a team of prominent lawyers stepped in, they collected DNA evidence proving Cruz couldn't have committed the rape. They also hammered away at the vision statement. At Cruz's third trial, Lieutenant James Montesano testified that he was on vacation in Florida on the day his detectives claimed they had called him about Cruz's vision. The judge angrily dismissed the case and set Cruz free...
...other great theoretical breakthrough of this century was the discovery by James Watson and Francis Crick of the self-replicating structure of DNA. Their thinking may make the 21st century a century of biotechnology, one marked by the manipulation of DNA in ways that produce everything from customized drugs to human clones...
Drexler was an M.I.T. undergraduate studying genetic engineering in the mid-1970s when he had his epiphany: if you could engineer DNA on a molecular level, why not build machines out of atoms, program them to build more machines and so on, until you had millions of infinitesimal nanobots, endlessly restocking the food supply, say, or swarming through the bloodstream eradicating disease, or building skyscrapers from industrial waste? If nanotech was viable, it promised a gleaming future of virtually limitless wealth and endlessly renewable resources...
Then, unexpectedly, he struck out when he proposed an implausible, three-chain helix for DNA. Several months later, in Cambridge, England, Francis Crick and I, apprehensive that Linus might bat again, found the double helix. Why Linus failed to hit this home run will never be known. His wife Ava Helen is said to have told Linus that he should have worked harder. I believe the decade following World War II may have had too many agonizing moments for the Pauling family...
