I have over a dozen new discoveries like this in my email backlog that I skimmed and saved as likely to be blogworthy here so expect more in the next few days as I work through it. I go into a political blogging frenzy for a few months once every four years and I’ve been derelict in posting science articles here as a result. It won’t happen again until 2012. I joined this blog shortly after the 2004 presidential election was over.
This science article is one those where the researchers variously describe themselves as “stunned”, “amazed”, “surprised” or something else that conveys the notion that theory didn’t predict whatever it is they found. I also watch for discoveries that are described as “unexpected” which conveys the same meaning – the underlying theory of evolution is deficient. Sound theories don’t result in unexpected observations.
Biologists Discover Motor Protein That Rewinds DNA
ScienceDaily (Nov. 2, 2008) — Two biologists at the University of California, San Diego have discovered the first of a new class of cellular motor proteins that “rewind” sections of the double-stranded DNA molecule that become unwound, like the tangled ribbons from a cassette tape, in “bubbles” that prevent critical genes from being expressed.
Read the whole article at the source above. Here’s the revealing part (my emphasis):
What this protein, called HARP for HepA-related protein, did astounded Kadonaga and Timur Yusufzai, a postdoctoral fellow working in his laboratory. The two molecular biologists initially discovered that this motor protein burns energy in the same way as enzymes called helicases and, like helicases, attached to the dividing sections of DNA. But while helicases use their energy to separate two annealed nucleic acid strands—such as two strands of DNA, two strands of RNA or the strands of a RNA-DNA hybrid— the scientists found to their surprise that this protein did the opposite; that is, it rewinds sections of defective DNA and thus seals the two strands together again.
