• Partial Fetus in Sister's Brain Supports Role of DNA Repeats in Development

    14 days ago - By DNA Science

    Startling images in the journal Neurology made the media rounds last week. CT scans show a partial fetus wedged within a space in the brain of its one-year-old sister. In photos, the removed potential sibling resembles a pink tadpole.
    The report, called a Teaching NeuroImage, is from four researchers at Beijing Tiantan Hospital, and entitled “Intraventricular Fetus-in-Fetu, With Extensive De Novo Gain in Genetic Copy Number.” That means the genome of the doomed fetus-within-a-fetus had lots of copies of certain short DNA sequences that aren't in the parents' genomes .
    With only two short...
