...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...
...fact, there may have been an evolutionary advantage to sluttiness. The females of our closest primate relatives, the chimpanzees and the bonobos, are not exactly paragons of sexual probity. A recent DNA study of chimp behavior in the Tai forest of Africa's Ivory Coast showed that despite the bullying of local males, the wily females were sneaking off so often that half their offspring turn out to be fathered by outsiders. Of bonobos, perhaps the less said the better, at least in a family magazine. These "pygmy chimps," as they are also known, share 98% of our genes...
Researchers aren't sure why chemotherapy boosts the effectiveness of radiation, though they have an idea. Radiation damages the DNA found in cancer cells. But all cells, including cancer cells, contain enzymes that repair broken DNA. Perhaps the drugs used in chemotherapy block the cellular repairmen from doing their job. The damaged DNA never gets fixed, and the cancer cells...
