    Various Species' Genes Evolve To Minimize Protein Production Errors  Jul 26, 2008
    ScienceDaily (July 25, 2008) Scientists at Harvard University and the University of Texas at Austin have found that genetic evolution is strongly shaped by genes' efforts to prevent or tolerate errors in protein production. Their study also suggests that the cost of errors in protein production may lie in the malformed proteins themselves, rather than the loss of functional proteins. (Science Daily)

    The DISCOVER Interview: Francis Collins  Feb 21, 2007
    What are you finding about the importance of known genes versus the "junk DNA" in between them ... It's a coordinated effort among 30 labs to identify all of the parts of the human genome that have biological activity, including the so-called junk DNA. We have found that there is a lot more action. (Discover Magazine)

    'Regressive Evolution' In Cavefish: Natural Selection Or Genetic Drift  Feb 17, 2007
    Regressive Evolution' In Cavefish: Natural Selection Or Genetic Drift. "Regressive evolution," or the reduction of traits over time, is the result of either natural selection or genetic drift, according to a study on cavefish by researchers at New York University's Department of Biology, the University of California at Berkeley's Department of Integrative Biology, and the Harvard Medical School.

    What is junk DNA, and what is it worth?  Feb 13, 2007
    com: Ask the Experts: Biology: What is junk DNA, and what is it worth ... What is junk DNA, and what is it worth ... In 1972 the late geneticist Susumu Ohno coined the term "junk DNA" to describe all noncoding sections of a genome, most of which consist of repeated segments scattered randomly throughout the genome.

    Drug-resistant HIV Easier To Detect With New Test  Jan 9, 2007
    Some retroviruses are thought to be harmless ("junk DNA" forms a large part of the human genome), but in the case of HIV it gets into immune system cells like T- cells and alters their behaviour. HIV spreads from host to host via body fluids like blood, semen, vaginal secretions and breast milk. (Medical News Today)

    - Richard Buggs  Jan 9, 2007
    Intelligent design is a science, not a faith. If Darwinists distinguished between science and their religious beliefs, we'd all be wiser, says Richard Buggs. (Guardian Unlimited)
