Scraps of ancient viruses make up 40% of our genome. They could trigger brain degeneration.Our genomes are peppered with DNA segments called retrotransposons that can move from place to place. When unleashed, some can kill nerves and promote inflammation — a discovery that may inspire treatments for neurodegeneration.
