...Ginny got a letter from the medical examiner's office. George's toothbrush and dirty T shirt that she had submitted the previous fall did not have enough genetic material to make a match. The examiner needed additional DNA from a child or sibling. Ginny could not face taking her daughter to the Manhattan morgue where the parts of so many husbands and fathers were being stored in refrigerated trailers, so she opted to have the DNA kit sent to their home. It arrived on Valentine...
...comparing DNA from humans, chimpanzees and other animals, researchers from the Max Planck Institute in Leipzig, Germany, and the University of Oxford in England determined that FOXP2 hardly changed during the evolution of mammals. But their analysis, reported last week in Nature, indicated a subtle genetic shift in the human family tree within the past 200,000 years. "The gene seems to trigger the development of the ability to move the mouth, lips and tongue as well as certain neural processes," says Wolfgang Enard, one of the study's German authors...
...very loose grip on reality. And a man who turns 60 and tells you he never felt better is delusional. He has forgotten how it was when your whole being leaped and bounded, before you turned into a lumbering galoot. Nature is relentless; it programs degeneration into our DNA. Even if you're positive-thinking, hopped up on Viagra, and your face has been lifted and stapled to make you look like a feral woodchuck, nonetheless one day you'll look like something from the lost lagoon and have the sex drive of a smoked salmon. Nature doesn't care...
...unburied and posed in such a horrific way that the man who came upon it begged the police dispatcher he reached to let him flee the scene. "Please hurry. I'm scared, and I want to get out of here," he said. The body was also loaded with DNA evidence. Law-enforcement officials interpreted this as the killer's warning that the police couldn't stop him and that he was free to strike again...
...discovery that life can thrive under horrific conditions is a major scientific advance. But it could also turn out to be hugely profitable. Extremophiles survive by manufacturing all sorts of novel molecules. Some digest harsh chemicals; some protect DNA against destruction by radiation; some stave off searing heat or freezing cold. Entrepreneurs are racing to turn these molecules into products, just as was done in the 1980s with Thermus aquaticus, the Yellowstone bug exploited in the PCR technique widely used today to analyze DNA...
