But this is basically a review. The actual research in this week's Nature is not by this UT Arlington lab, but instead by Horie, et al, from Tokyo ( http://www.nature.com/nature/journal/v463/n7277/full/nature08695.html http://www.nature.com/nature/journal/v463/n7277/full/nature0... ) That 8% of human DNA comes from viruses is interesting, but not new; this has been known for at least a few years now. What is interesting about the new findings is that this is the first non-retrovirus found to insert DNA into the human genome.
